Understanding travel demand patterns is crucial for effective traffic management, policy-making, and transportation evaluations. Digital twins have emerged as a significant tool in tackling this challenge, where accurate traffic simulation outcomes depend on high-quality data. Essential to most transportation analysis is the knowledge of road users’ origin and destination (OD), enabling route planning, traffic pattern assessment, and system optimization. This information is typically represented in an Origin-Destination (OD) matrix. However, direct observation of every traveler’s origins and destinations is impractical, necessitating the estimation of time-dependent OD flows from available data — a persistent challenge in the field. Direct methods like measurements, interviews, or surveys are often too costly and challenging to implement. Instead, aggregation methods using traffic counts and other data sources offer reasonable estimates. This paper reviews several approaches for estimating OD matrices for vehicles, bicycles, and pedestrians. This review considers various data sources, methodologies, and preprocessing techniques tailored to each mode of transportation. Subsequently, we propose an integrated framework for OD estimation across these modes, factoring in the unique travel demand influencers and available data for each. We acknowledge practical constraints and provide a meaningful contribution to demand modeling that serves as a baseline for digital twins

In this study, we conducted a comprehensive survey involving a substantial sample size (n = 6,405) of urban daily commuters across four European nations (Germany, the United Kingdom, Poland, and the Czech Republic). Our investigation contributes to an enriched comprehension of the user dynamics associated with Mobility-as-a-Service alternatives and their interrelation with public transit modalities in the context of travel preferences. Specifically, we researched the responsiveness of participants to variations in pricing and travel durations. Additionally, we examine the tendencies of various participant categories, stratified into distinct segments based on shared attributes, toward the adoption of public transportation, MaaS solutions, or private vehicular transport. Our findings highlight the essential role fundamental mobility determinants, such as price and travel time, play in influencing the likelihood of opting for a specific transportation modality. This phenomenon was particularly discernible within the "Unspecified Users" group, which gives us options to alter their behavior. The analytical framework used in our study that combined several mathematical modeling tools provided insight into the choices people make when choosing between different travel options, and our findings may be used by decision makers to create better and more informed approaches to promote sustainable alternatives to the use of cars in urban settings.

This study investigates the effect of meteorological conditions on the traffic flow and its speed in Prague, with a focus on variations in temperature and precipitation. Using data from strategic traffic detectors operated by the municipality of Prague and sensors from the Czech Hydrometeorological Institute, it explores the correlations between weather fluctuations and traffic flow parameters. The findings reveal an influence of weather on traffic flow behavior, revealing that extremes in temperature and precipitation significantly affect both traffic flow and speed. This research contributes to a deeper comprehension of the mobility of humans and goods (city logistics) within urban settings. Importantly, it underscores the necessity of integrating meteorological data into transport management and planning, particularly in the context of ongoing climate changes.

Understanding individual travel behavior is crucial for developing effective travel demand management strategies and informed transportation policies. This study investigates the factors influencing individuals’ mode choices by analyzing data from a comprehensive travel survey. We employ a deep neural network model to explore the relationships between survey variables and respondents’ transportation mode preferences, focusing on both observable and latent factors. The SHAP method is applied to interpret the model’s outputs, providing global and local explanations that offer detailed insights into the contribution of each variable to mode choice decisions. By identifying the key determinants of mode selection and uncovering the complex interactions between these factors, this research provides valuable insights for designing targeted policies that can better address transportation needs and influence sustainable travel behavior.

There is a raise in public awareness on environmental and health issues in recent years, therefore many municipalities changed their transport policy direction to become more sustainable, especially active mobility based. This study makes use of an activity-based demand model to simulate urban mobility and policies for sustainable transport modes in the Usti nad Labem district using an agent-based model simulator driven by a co-evolutionary algorithm. Two policy scenarios were created by considering the transport literature and analyzing the characteristics and behaviors of citizens as well as the properties of the study area. Three scenarios—the actual situation, a cycleway-infrastructure case, and a bus priority case—were simulated for the study area with MATSim software. Both policy scenarios resulted in a decrease in car usage, with a higher drop seen in the cycleway-infrastructure scenario. 9.11% higher public transport ridership and 2.45% more of public transport modal share are observed in the bus priority compared to the actual situation, however the car-related emissions did not decrease. 6.36% more of cycling modal share was also noticed in the cycleway-infrastructure scenario which, the transport modal shift is enhanced by 2.6 more times than in the bus priority scenario. Car driving hours were significantly reduced in the cycleway scenario (5535 h less in a day) where 445.3 tons of car-related CO2 emissions would be saved annually, therefore environmental benefits of cycling modal share increase in the study area is undoubtable in long-term.

Traffic congestion is one of the most significant impacts of constantly increasing mobility demands in cities. In this paper, we conceptualize a complex multi-aspect algorithm for quantification of the socioeconomical impact of congestion. This algorithm can be a very powerful tool to evaluate recurrent congestion in cities in terms of quality of life (QoL) and economic assessment justifying investments. It is also a forecasting tool evaluating planned interventions into urban transportation systems such as constructions, reorganizations, and various special events. The proposed preliminary algorithm takes into consideration the value of time, the fuel consumed, and the cost of produced CO2 emissions. With the provided example, it was shown that in case of Prague city daily congestion related cost can exceed and overwhelming 800.000 EUR/day. This is a considerable amount when considering its daily base repetitiveness.

This work summarizes results and findings of a Czech national scientific project “SMART City – SMART Region – SMART Community” that took place between years 2018 and 2022. Its objective was to understand decision making processes related to the travel mode choice (travel behavior research). Particular focus has been put on shared mobility, micro mobility and mobility-as-a-service (MaaS) in general. Main driver of the study was the need to understand reasons why people choose cars as their preferred travel mode in order to propose and deliver policies leading to increase attractiveness of other transport modes.

With the constant and ever-growing pressure from governing bodies for increased sustainability of transportation systems, the need for changes in the travel behaviours of the inhabitants of suburban and urban areas seems inevitable. Thus a shift from cars to vehicles with higher occupancy rates or other more environmental friendly travel modes needs to be a priority. This requires understanding the reasons why people choose cars as their preferred mode of travel for commutes in order to make informed decisions about how to encourage changes in commuter travel behaviors. This paper presents a case study of four medium-sized Czech towns, including a survey concerning pre- and post-COVID-19 travel habits focused on identifying and understanding the willingness of car-dependent commuters to change their mode of travel choice. This three-stage survey revealed a small, COVID pandemia -based effect on the habits of respondents and helped to identify sensitivities survey participants had to particular travel parameters and characteristics that might be used by municipalities to implement informed policies that could lead to changes in travel behaviours.

Wastewater treatment is a process to improve the water quality making it suitable for discharge back to the environment. Since wastewater majorly comes from humans, wastewater treatment plants are required in urban areas to improve the quality of the environment and life in cities. In Ecuador, wastewater treatment is frequently solved by a waste stabilization pond system which offer completely natural purifying processes. Unfortunately, most of the ponds are not in optimal conditions and show deficiencies in hydrodynamics and sediment removal. The objective of this work was to demonstrate how a hydraulic improvement of a maturation pond can be achieved by applying Computational Fluid Dynamics. Ansys Fluent software was used to perform a two-dimensional hydrodynamic simulation of the maturation pond in the Playas canton. Several interventions in the pond design were proposed and studied from the hydraulic efficiency point of view. It was generally concluded that the use of the Computational Fluid Dynamics is beneficial to design, analyze and optimize complex waste stabilization pond systems, resulting in an increased quality of life in cities.

In a world in which Intelligent Transport Systems (ITS) are increasingly being installed on highways, the proper calibration of ITS algorithms is emerging as an essential component of such systems. The key to calibration is profound and correct understanding of reactions by drivers to ITS interventions. Speed compliance is a special kind of driver behavior, highly related to resultant road safety. This paper, using data gathered from a representative sample of 39 research participants in a dynamic driving simulator experiment in the Czech Republic, presents an approach for modeling driver speed compliance based on socio-demographic characteristics. In this approach, logistic regression model was applied to understand the factors influencing driver speed compliance. The results of this study support the goal of establishing optimal speed limits for drivers on Variable Message Signs on the Prague Ring Road by addressing issues related to driver speed compliance. These findings provide the basis for policy development aimed at ensuring the consistent and practical design of Variable Speed Limit systems on Czech highways and beyond.

In this study, an activity-based travel demand model of the Ústí nad Labem district (Czech Republic) is created. To do this, an advanced travel demand synthesis process is presented by utilizing the Eqasim framework, which is a pipeline-processing, initial raw data to simulation step. The framework is extensively modified and extended with several algorithms in order to utilize multiple data points for increasing realism in mobility for travel demand models. Two major extensions are provided. First, the pipeline framework is improved to estimate inbound and outbound trips of the study area, comprising a main city and 23 surrounding municipalities. The extended framework assigns synthetic gates for the study area as hubs for the inclusion of inbound and outbound trips. Second, the pipeline framework is advanced to provide a more compatible match of travel destination and activity location state. To do this, the extended framework assigns a capacity for each facility identified for the study area, the expected number of visitors to each facility, and the number of residents in each building. The resulting demand model is presented and the generated trips are evaluated based on locational, transport mode, and sociodemographic characteristics with origin–destination (OD) bundling. Additionally, distribution analyses of the present model are conducted to understand the matching results on a detailed level. The results demonstrate that the present model provides a reasonable output for transport researchers when testing different mobility scenarios and the provided extensions helps them to reduce implausible reflections of the distribution of travel and activity characteristics in household travel surveys while creating demand models, thus increasing realism. Lastly, open-source playground and code repository for further future improvement of synthetic travel synthesis methods are created, which enhances a deep understanding of the preparatory and methodological backgrounds required for complex activity-based simulations in order to inspire transport planners.

Road construction and maintenance activities cause traffic congestions and delays and present challenges for ensuring the safety of both motorists and road workers. While urban areas are well-equipped with traffic devices, in the case of highways our chances to collect traffic data and control traffic flows may be limited. Then the use of a temporary Highway Traffic Management System seems to be a suitable solution. Although the impacts of its deployment are addressed by many theoretical studies and demonstrated on traffic simulation models, there are not many references dealing with field tests. We provide results of the practical evaluation of the temporary Highway Management System installed and tested on the main highway in the Czech Republic during the road works period. Before-after analysis of collected traffic data was performed to prove the importance and positive impact of the proposed solution. We demonstrate an over 20% increase in the capacity of the roadwork zone and an almost 30 seconds decrease in average delay for one vehicle Highway administrators can use the results to justify investments into the temporary deployment of mobile traffic management systems.

Smart Cities seek to optimize their systems by increasing integration through approaches such as increased interoperability, seamless system integration, and automation. Thus, they have the potential to deliver substantial efficiency gains and eliminate redundancy. To add to the complexity of the problem, the integration of systems for efficiency gains may compromise the resilience of an urban system. This all needs to be taken into consideration when thinking about Smart Cities. The transportation field must also apply the principles and concepts mentioned above. This cannot be understood without considering its links and effects on other components of an urban system. New technologies allow for new means of travel to be built, and new business models allow for the existing ones to be utilized. This Special Issue puts together papers with different focuses, but all of them tackle the topic of smart mobility.

Urban areas are growing all over the world. As a consequence, a larger volume of people and goods has to move to a larger number of different locations on a daily basis. This leads to more traffic congestion, longer commutes, use of different travel modalities, and increasing pollution. There is thus a need for more intelligent transportation and smart infrastructure, as well as changes in travel behavior.

Urban mobility is currently facing a variety of challenges. Increasing emission levels in cities, growing numbers of private vehicles and constantly changing needs and requirements of the population are only some of them. New mobility concepts and business models are currently emerging in response to these volatile conditions, primarily through improvements in IT infrastructure and the profitable collaboration of various players. Mobility as a Service (MaaS) is one of those innovative mobility concepts trying to cope with the current challenges. This paper provides first insights on the characteristics and attitudes of potential MaaS users in order to understand the drivers for a higher willingness to use. The results are gathered with an online survey based on a sample of n = 6000 regular commuters within England, Germany, Czech Republic and Poland. Additionally to the development of a User Behavior Model, the focus also lies on the analysis of undecided users. Comparing the attitudes of participants who show a high willingness to use MaaS with those who are still undecided provides important insights on how to attract a specific audience and increase the usage of Mobility as a Service. The data provides information that the average undecided user is of higher age and has a lower income. Furthermore, the results show significant evidence that the personal opinion towards shared economy, environmental friendliness, and social influence does impact the willingness to use MaaS. Contrary to existing research, travelled distance does not influence the likelihood to use MaaS.

In the last years, with new topics such as smart cities emerging, there is a lot of progress with respect to gathering new data, transforming them into information and knowledge and to share and enhance such knowledge among different fields. This is true also for traditionally closed environments such as railway stations. We can see many new sensors emerging. They do not monitor only the movement of the trains. A lot of attention is newly paid to the movement of people. For this different video detection systems, ultrasonic technologies, even weight sensors installed in vehicles are often used to learn more about travelers’ behavior. Such data can be used for many different aspects, such as safety, security or even control and optimization. In this paper, we do not look primarily at the different technologies used in sensors to monitor presence and movement of travelers (automated people counting – APC systems). Our aim is to define the possible usage of such data. System engineering approach is used to utilize the findings from literature and project review. Based on a state-of-the-art analysis, we identify the major actors and prepare use cases defining the way how they can use and benefit from the data. A classification of the technology is provided to better explain the needs of particular use cases. The use cases are also further classified according to strategic, tactical, and operational control level.

Carsharing is a relatively new and growing mobility service in many cities. Although there are numerous carsharing initiatives in operation around the world, it is still not clear how they will affect overall travel behavior. Understanding the effects of carsharing when combined with other existing travel modes is an important pre-requisite for decision-makers for them to be able to positively utilise the benefits of carsharing services. Such new mobility services need to be incorporated into existing modelling tools to reliably evaluate the impact of specific measures and policies. The presented study provides an insight into one aspect of such models: the use of carsharing for various trip purposes by users with different socio-demographic characteristics and attitudes. We identify variables that should be used for computing the utility function for users with different backgrounds, perceptions, and preferences. In this study, existing users of a carsharing company operating in various Czech cities participated in a survey and their responses were paired with records of their real carsharing usage patterns. To reduce the number of variables, principal component analysis was used, mainly with attitudinal and perception questions. The principal components based on survey respondents' attitudes towards carsharing and socio-demographic and other variables were used in logistic regression to identify parameters that most significantly influence various purposes for trips. The results confirm the hypothesis that trip purposes differ significantly among carsharing users and need to be incorporated into macroscopic carsharing usage models. These findings can assist municipality representatives and transport companies in considering carsharing as a valid and sustainable travel mode in traffic models and studies.

The field of smart cities and the latest problems in this area of expertise accent the need for interaction among different areas, such as transportation, energy management, education, buildings and others. New technologies and new methods allow for a fast development of each of the areas and of the city itself. At the same time, there is a need for further involvement of citizens and different stakeholders in the decision-making process within cities. In order to demonstrate the impact of a new policy (e.g., building a new shopping center) on certain city aspect (e.g., transportation), simulation models have been recognized as probably the best approach. Unfortunately, there is still no tool that would allow the stakeholders to evaluate the impact of such a policy on a city as a whole and from multiple perspectives. Dedicated simulation frameworks should be used in cooperation, one for transportation, one for energy grid management, another for its impact on the environment until all important aspects are covered. This paper describes a complex tool aiming on overcoming such complicated demands and giving the policy makers one tool to assess impact on different interconnected fields. It combines existing dedicated simulation frameworks into a complete software suite that can combine even contradictory results into one or more performance indicators. This can be used as a decision support system and help in involving citizens into the city government and planning. This article focuses on the utilization of mobility modelling in such a software.

owadays, urban road tunnels are considered to be independent entities within a city. Their interactions with the rest of the city and vice versa are usually not considered and, if they are, are only considered in a limited way (for example, through the nearest traffic controller). Typically, only the traffic parameters and not the environmental impacts are considered. This paper has two major objectives. First, we provide a systemic view on a road urban tunnel. The major focus is on the interfaces between the tunnel and the rest of the city and the way they will be managed. We are providing a tool to take into consideration a sustainable development of a tunnel (i.e., not only traffic flow parameters such as average speed, but also environmental and societal characteristics). This model expresses the actual traffic situation in a monetary form (i.e., cost of congestions). The second objective is to provide a new road urban tunnel control approach that follows the original methodology and systemic view described in the paper. If the tunnel is controlled autonomously, which corresponds to the current state-of-the-art in many cities, the algorithm decides to close it based on only local parameters. However, the proposed new algorithm takes into consideration not only the traffic situation in the tunnel (expressed by the parameter traffic density), but also the actual traffic situation within the city (expressed by its level of service (LOS)). This allows more environmentally, socially and economically sustainable oriented road urban tunnel management. The described algorithm is demonstrated on a specific example of the tunnel complex Blanka in Prague.

An analysis of survey data is a fundamental part of research concerning various aspects of human behavior. Such survey data are often discrete, and the size of the collected sample is regularly insufficient for the most potent modelling tools such as logistic regression, clustering, and other data mining techniques. In this paper, we take a closer look at the results of the stated preference survey analyzing how inhabitants of cities in Thailand, Poland, and Czechia understand and perceive "smartness" of a city. An international survey was conducted, where respondents were asked 15 questions. Since the most common data modelling tools failed to provide a useful insight into the relationship between variables, so-called lambda coefficient was used and its usefulness for such challenging data was verified. It uses the principle of conditional probability and proves to be truly useful even in data sets with relatively small sample size.

While there are several partial solutions to model some aspects of cities (e.g. transportation or energy), there is no framework allowing modelling of a complex system such as a city. This paper aims on providing a solution that can be used by practitioners to model impact of different scenarios and smart city projects encapsulating different subsystems, such as transportation, energetics or, for example, eGovernment. The term “smart cities” is classified into Systems Theory, particularly focusing on Cyber-Physical Systems. This classification is further elaborated to define a new term, so-called Smart City Agent (SCA). The SCA is considered as the main building block for modelling smart cities. The approach within this paper however stresses the interconnection of different systems within a city. Its’ strength is in better exchange of data and among heterogeneous agents. This information management approach is the missing key in the growing market of partial smart city solutions as it will allow simulation of solutions in complex systems such as a city. The suitability of usefulness of the proposed approach is demonstrated on a use case dealing with charging of electrical vehicles. The results show that the approach is suitable for modelling of dynamic behaviour.

The European Union (EU) has set rather ambitious goals for reducing emissions and improving related environmental concerns. The majority of EU effort towards reducing emissions is aimed at vehicle manufacturers, mandating development of more efficient engines in order to reduce emissions. We propose a complementary approach to help reach the EU goals. Due to the need for motorists to repeatedly stop and accelerate while driving in urban areas, overall emission rates are observed to be higher in these environments than on open motorways. As a result, management algorithms that focus on harmonising the flow of traffic in urban centres have the potential to greatly reduce urban emission rates. In this paper, we propose a set of functionalities in form of ”use cases” in order to illustrate the inefficiencies of urban traffic flow by utilising cooperation between vehicles and infrastructure. The major contribution of this paper is in addressing the potential positive impact of such measures. The results and the expected effects of the algorithms were determined using a microscopic traffic simulation model. Importantly, this approach also addresses the transition phase, when only a limited number of cooperative and automated vehicles1 (CAVs) will be introduced into traffic, resulting in a mix of automated and non-automated vehicles on the roadways. We demonstrate that introducing CAVs into traffic can lead to significant progress towards EU emissions targets, even for lower penetration levels. According to our models, full use of CAVs on roadways would lead to a CO2 emissions decrease of 10–19%.

With ever-changing cities and growing populations it becomes progressively more difficult to assess which infrastructural changes are beneficial and which are possibly destructive long-term. It is almost impossible to find experts that understand the wide range of aspects surrounding smart cities as well as their interrelationships. Decision makers need a tool that helps them to set certain policies and evaluate their impact on key performance indicators (KPIs). This paper presents a multicriteria evaluation method based on assessing infrastructural changes in the city combining different modeling tools to gather sufficient data to assess and evaluate different alternatives. The proposed approach is demonstrated on a case study from Prague 6, Vitêzné námêsti.

Cooperative and automated vehicles (CAVs) are often considered a mean to improve quality of life in cities, the traffic flow parameters in particular. This paper provides some evidence based on microscopic traffic simulation on how the effects can really be. Important is that the particular use cases are not built in vehicles only. We focus on so called cooper-ative environment and advanced traffic control measures. This paper describes the impact of CAVs on a cooperative urban environment, resulting from a European research project - MAVEN. We clearly demonstrate that a proper integration of CAVs into city traffic management can, for example, help with respect to the environmental goals and reduce CO2 emissions by up to 12 % (a combination of GLOSA and signal optimization). On corridors with a green wave, a capacity increase of up to 34% was achieved. Already for lower penetra-tion rates (20% penetration of CAVs), there are significant improvements in traffic performance. For example, platooning leads to a decrease of CO2 emissions of 2,6% or an impact indicator by 17,7%.

Transport creates an integral part of people's lives and significantly affects the quality of life and the environment in cities. Because of the increasing number of cars in cities, it is not sufficient to focus just on an improvement of traffic control algorithms or other intelligent transportation systems and solutions. It is necessary to significantly decrease the number of cars in cities, i.e. to decrease the demand for travel using personal vehicles. In order to do that, researchers try to understand the process of how travel choices are made and to learn about the potential of travel mode change. A lot of research exists in this field. A common approach adopted also in the presented work uses discrete choice experiments as a mean to learn about travel behavior. Scientific results indicate that differences among different countries and cultures must be taken into consideration and research methods cannot be simply adopted without understanding the local context. For such reasons, this paper demonstrates the importance of understanding the local perceptions and their impact on the experiment design. To optimize the experiment design, three focus groups took place in Ústi and Labem Region (Czech Republic) during November 2019 with the aim to analyze local specifics and attitudes of local inhabitants towards different transport regulation measures. This case study proved the importance of pretesting experiments before performing them, the usefulness of FGs when designing the experiments and an important role of local specifics.

Tato disertační práce se zabývá problematikou makroskopického dopravního modelování. Cílem práce je rozšířit standardní postup výpočtu makroskopického dopravního modelu o model, který pro každou zónu dopravního modelu určuje podíl jednotlivců vlastnících předplatní jízdenku na veřejnou dopravu nebo disponujících osobním automobilem. Využívání těchto nástrojů mobility není uvažováno jako pouhý vstup do dopravního modelu, ale používání těchto nástrojů je uvažováno jako závislé na různých faktorech popsaných v této práci. Hypotézy byly ověřeny multinomiálním logitovým modelem, nested-logit modelem a smíšeným logitovým modelem. Disertační práce představuje nový postup, který zahrnuje tyto faktory do makroskopického dopravního modelu.

Smart city has several definitions. Typically, it is an alliance of subsystems that have following objectives: improvement of quality of life of citizens, better use of limited resources and best use of existing infrastructure. Transportation as one of the most important subsystems shall be thus understood as one player working together with energy management, economy, eGovernment, and others. Synergy is the key to successful implementation. In order to be able to aim at the joint objective function and any synergy, the different subsystems must “understand” each other. Ontology has been acknowledged to be the most common tool to do that. To prepare an ontology for a domain (for example transportation) is a complicated task. In order to do that in a city, where there are several subsystems with complex behaviour is even more challenging. It is very difficult if not impossible to get experts from different fields to prepare a common ontology. In this paper we address the issue of Smart City Design and propose a pragmatic method to prepare an ontological knowledge system using the knowledge of various expert groups. A new concept, so call a knowledge matrix, is defined and used to enable cooperation of experts from different fields. We believe this can further help in implementation of any smart city projects. In order to demonstrate the approach, transportation domain is used as an example for the ontology design. The approach will be further validated within two case studies that are also introduced within this paper: Smart Evropská street in Prague and within a project Smart City – Smart Region – Smart Community, where a transport behavioristic model is being developed based on the ontology described within this paper.

Complexity of cities has for centuries been a research question across a wide range of disciplines. Cities are live organisms evolved by interactions of various heterogeneous subsystems. They are not only dynamic but also spatially distributed. Additionally, they involve humans interacting with the physical subsystems (so called cyber-physical systems). Urban planners today face a difficult task of designing new and redesigning the current urban spaces in a way to make them more liveable and walkable (the key objectives of smart cities). Yet those responsible, the city planners or urban designers still only guess about an optimal street design. This paper provides an overview of literature and discussion of potentials of space syntax, technique developed during the last 35 years that proved itself effective in city planning procedures. Space syntax provides a set of theories and methods for analysis of spatial configurations. It allows us to link human societies and space and to describe relations between them. These methods showed immerse potential to a wide range of disciplines and their integration is crucial for the field of smart cities.

Smart Cities become a phenomenon that is strongly linked to people and their quality of life, technologies, data, information and automation. All these will be present in future transportation that is expected to be connected and automated. While advances in vehicle automation can make cities smarter, safer, cleaner, or more energy efficient, it can also make traffic management increasingly more complicated. As a result, current traffic management tools and policies may become inefficient. Since we already experience systematic growth in Smart City technology around the world, new sets of rules and policies to protect cities and their citizens in the emerging digital and automated era must be developed and enforced. Solutions such as automated driving introduce new challenges and opportunities for climate change mitigation and improvement of traffic conditions in densely urbanized city centers. There are different approaches to integrate autonomous vehicles and their novel functionalities into the traffic management. In this paper we demonstrate such functionalities and their impact on different traffic and environmental parameters based on traffic microscopic simulation adopted to such connected functionality. The results clearly show the need to carefully and individually analyze and prioritize the impact of the CAVs functionalities for each city and each traffic situation individually, as they might have contradictory effects on traffic. The key performance indicators must be defined and the functionalities carefully integrated into the existing traffic management. This is true for the mixed traffic during the early introduction of CAVs in cities even more.

In the paper, the new vision of “Smart City 5.0” is presented. It is based on a previously developed model of Smart City 4.0 and implementing the concept of the complex adaptive system for balancing conflict interests of different city actors. These actors can include business, transport, energy and water supply providers, entertainment and other services and can be unified based on resource and demand model. The paper describes the general principals, functionality and the architecture of the digital multi-agent platform for creating eco-system of “Smart City 5.0”. It is designed as holonic p2p network of smart services and technological components for supporting demand-resource relations. It is shown that in proposed eco-system smart services can interact both vertically and horizontally supporting competition and cooperation behavior on the basis of specialized protocols of p2p network. In the future, each smart service is considered as an autonomous cyber-physical multi-agent system which can be decomposed on a lower level of smaller services recursively. The first prototypes of smart services and their interaction are presented, the next steps for future research work are outlined.

A city ring road with the parameters of a highway forms a part of the infrastructure of a modern city. The introduction of automated highway management to the city ring road moves it towards a smart city. This paper presents the framework model which was created with the aim of developing an agent-based control within the highway management in the future. The model was created in the multi-method simulation tool Anylogic since it allows the testing of both traditional rule-based algorithms and agent-based control. It is universal enough, thus, it can be used to compare different approaches to highway management. In this paper, a literature review focusing on the Multi-Agent Systems and their application in traffic and transportation is performed. Based on the above mentioned review, a system architecture for agent-based traffic control is proposed and the framework model is described.

Autonomous driving is a very important topic aiming on changing mobility in smart cities. A lot of research has been dedicated to development of vehicles without drivers and quite many tests and real world demonstrations have been reported especially in the last years. The first expectations were very optimistic. Researchers as well as general public expected high positive influence in the congestions, travel time and other mobility aspects. However, the latest research questions these purely positive expectations and suggest that autonomous driving might have positive or negative effect based on city policies in place.In order to gain a better understanding about the current expectations of general public about the impact of autonomous driving, a survey has been conducted as part of a European project MAVEN. This paper provides a short description of the survey design and then summarizes the main findings and results of this survey. The results can get us a better way to understand the feeling of citizens about autonomous vehicles and the transition to full automated cities.The results confirmed the general trends and at the same time gave us more insight into the special questions related to MAVEN use cases. These findings will be further validated in simulation experiments.

The main objective of this paper is to demonstrate a novel method for modeling smart cities and to introduce a use case study related to charging of electric vehicles. This use case is focusing on the research question: how many charging stations are needed to fulfill the dynamic demand for charging of electric vehicles. If electric vehicles become a mass product, it will be necessary to build many charging stations. On the other hand, the charging time will be significantly different from conventional cars and hardly as fast as conventional cars have (at least in the near future). In case of trucks, this will be even bigger difference. We can expect significant improvements in the speed of charging of batteries in the future. In this paper, we do not want to predict what will be the future, but rather demonstrate what will be the impact if we consider the number of charging stations, electric vehicles and charging time. This is a dynamic problem and the usage of a novel SMACEF framework using Multiagent systems is proposed as a suitable tool for this use case, as well as other smart city related problems.

Nowadays the term Smart City is widely used and almost every city aims to become “Smart”. Unfortunately, the definitions of what Smart means differ and there is not a single accepted one. Often a technocratic view is adopted and the actual goal—make city more liveable—is not kept in mind. In this paper, a new approach to initiate and develop Smart City model is provided. A unified model is one way to describe the processes within such complex and heterogeneous system as Smart City. It is based on the similarity to the well-established framework called ITS (Intelligent Transport System) architecture. First, an overview of the Smart City initiatives and key principles that often require change of the way how we think of projects is provided. Further, the objectives and approach to national ITS architectures are described and discussed, mainly aiming on its limitations for the practical use especially in the context of Smart Cities. Finally, this paper provides a guidance on how a Smart City Architecture shall be established to overcome the system complexity and to reduce its dimension in terms of volume of required data flow. The new approach is based on decentralized intelligence, where a number of processes are carried out at the level of so-called building blocks. Multi-agent systems are proposed as a design tool for the particular building blocks.

Travel behavior is certainly an important study area in the field of smart cities. Influencing travel behavior or changing travel patterns (for example by motivating travelers to use alternative travel modes) has the potential to lower congestions and thus significantly affect the quality of life as well as the environment – the key objectives of smart city projects and initiatives.This paper provides a review of existing research into data collection methods dealing with the topic of travel behavior, mainly with changes towards using alternative travel modes. First, a theoretical classification of survey methods is provided. Next, their advantages and limitations are demonstrated on real-world examples. Finally, the findings of this analysis are formulated into recommendations for new research into the potential of smart city measures to influence transport behavior in the Ustí nad Labem Region of the Czech Republic.

Preparing the next generation of engineers, scientists and decision makers requires the development of new teaching strategies that follow smart cities philosophy: collaborative, inclusive and focused on specific needs of the region. The University of Texas at El Paso (UTEP), USA and University of Guadalajara (UdeG), Mexico, addressed the challenge of creating a new international course on smart cities study abroad program that leverages the long-term relationship of UTEP with Czech Technical University (CTU), Czech Republic, and industry partners in El Paso and Guadalajara, especially IBM Mexico. This program is highly interdisciplinary, involving four departments in the College of Engineering at UTEP and the Department of Information Systems, Centro Universitario de Ciencias Economico Administrativas at UdeG. Input from city officials in Guadalajara and El Paso along with industry partners was key in designing this novel program. Thirty-two students from UTEP and 32 from UdeG have successfully completed this program which will launch again on its third edition this year. The program included problem-based learning strategies as well as cultural, industry-led activities, culminating in a Smart Cities Hackathon competition. This articles reports on the planning, development and results of this study abroad program, challenges and lessons learned.

V poslední době se téma takzvaných autonomních vozidel stává velmi populárním. Většina výrobců automobilů se věnuje rozvoji technologií podporujících kooperativní či autonomní vozidla. Pokročilá senzorika či např. matematické modely pro plánování trasy vozidel v rámci jízdních pruhů jsou témata zpracovaná poměrně detailně a spolehlivě výrobci automobilů. Zároveň se v novinách často setkáváme s informacemi o pilotních testech či autonomních vozidlech v reálném provozu. Může se tedy zdát, že existuje velká připravenost na rozvoj autonomních vozidel. Autonomní vozidla ovšem nepochybně změní i pohled na management a řízení dopravy ve městech.

The proper functioning of critical points on transport infrastructure is decisive for the entire network. Tunnels and bridges certainly belong to the critical points of the surface transport network, both road and rail. Risk management should be a holistic and dynamic process throughout the entire life cycle. However, the level of risk is usually determined only during the design stage mainly due to the fact that it is a time-consuming and costly process. This paper presents a simplified quantitative risk analysis method that can be used any time during the decades of a tunnel’s lifetime and can estimate the changing risks on a continuous basis and thus uncover hidden safety threats. The presented method is a decision support system for tunnel managers designed to preserve or even increase tunnel safety. The CAPITA method is a deterministic scenario-oriented risk analysis approach for assessment of mortality risks in road tunnels in case of the most dangerous situation – a fire. It is implemented through an advanced risk analysis CAPITA SW. Both, the method as well as the resulting software were developed by the authors’ team.

Satellite technologies are widely used in many areas of modern society in general and in smart cities in particular. Improved traffic management, air quality monitoring, emergency management, geospatial distribution, management of critical energy infrastructure are examples of the tasks where using satellite technologies can give significant contribution to sustainability and safety. Proper operation of satellite systems is needed to achieve that. This requires solving a number of tasks, one of which is scheduling tracking, telemetry and command (TT&C) ground stations to carry out communication sessions with satellites. Service actions and transmitting a plan for payload operation such as Earth observation or radio broadcasting are performed during that sessions. In this paper, the authors discuss mathematical formulation of TT&C ground stations scheduling problem in order to analyse possibilities to increase the quality of schedule and efficiency of its adaptations. Possible approaches to achieve the goal, and factors influenced on parrying emergency situations are demonstrated. Approaches for monitoring the current situation and preparing data about it are proposed. Possible ways of its improvement are discussed, basic idea of decision support system to determine state of ground stations is proposed. Evaluating the efficiency of changing schedule of TT&C ground stations using proposed approaches and tools is given. The proposed approaches can help to ensure performing both planned and emergency tasks of satellite systems in order to ensure normal work of many services in smart cities.

The topic of Smart Cities is nowadays very broadly discussed. In order to be able to move beyond theory and make some practical progress, the concept of building blocks shall be adopted. In this paper, we address one particular building block - Smart Campus - and try to understand its key features. University is typically a part of most big cities and forms a unique environment. Smart city theory clearly states that improving the quality of life of particular citizens shall be the main objective. Even though a university has also different stakeholders, students form a homogenous group with often common objectives. The objective of this paper is to propose a method to learn about student preferences and perception of different smart cities with respect to university campuses. For this reason, design of a survey which can be used by different universities to learn about the expectations of the end users - students - with respect to the smart concept is presented and discussed. Additionally, results of two pilot evaluations are presented. On purpose, two universities with rather different background and different cultural background were selected: Czech Technical University in Prague (Czech Republic) and Thammasat University in Thailand. A pilot survey was executed and the analysis of the results using basic econometric methods, inferential statistics and logistic regression is provided.

Driver behaviour is a crucial factor not only with respect to trac safety but also when considering trac management systems. Modern Intelligent Transport Systems (ITS), such as Variable Speed Limit (VSL) system, enable real time dynamic trac management using actual trac data. However, in order to achieve an eective system, it is crucial to provide its speed limitation decision algorithm that is based on actual driver behaviour and not on theoretical expectations. Proper understanding of the driver decision making process and driving psychology is a key to eective and resultful trac management systems of the future. In this paper authors describe their study aiming to create a driver behaviour model with respect to VSL system based on data from driving simulator experiment. The resulting model is to be further ap- plied to data of Czech drivers' population in order to create background for future microsimulations of trac and wide range of objectives connected to calibration, analysis and deployment of future VSL systems in country.

Automated driving has become an important research trend in the field of cooperative intelligent transportation systems and their applications in smart cities. Automated driving both increases road capacity and eliminates human errors, one of the most common reason of traffic accidents. Both these aspects influence significantly the quality of life, which is a major goal of smart city initiatives. Management of automated vehicles by urban road infrastructure is a rather new subject and not so much practical development has been reported yet. Unfortunately, the available information is spread over fragments within other resources dealing with automated vehicles. In this paper, we provide an overview of major functionalities that have to be provided by both road infrastructure and an automated vehicle so that the vehicle can optimally navigate through an urban network with signalized intersections and we review the state-of-the-art publications providing approaches relevant to these core functionalities.

Safety is one of the most important aspects when designing a road tunnel system. Apart from the general design of a road tunnel, different technological safety systems can contribute to increased safety. There is, however, no agreed methodology on how to evaluate such systems prior to their design and installation. In this paper, it is recommended that the time required to detect a fire and warn people about it in the tunnel be used as a quality criterion since it has a direct effect on the probability of saving lives. In their previous paper, the authors proposed a fuzzy system called SAFECALC for effectively evaluating fire sensors and warning systems in tunnels, even in the early design phase. The biggest challenge in designing a fuzzy system is the original identification and calibration of such a system. For that reason, this paper focuses on the identification stage and, using the example of a linear fire sensor, it suggests a new methodology for performing such early level calibration. This methodology consists of several steps and, after the original design of the system, it uses inputs provided by experts in the field (via surveys and brainstorming) for fine tuning of the system. A physical model is used to simulate the propagation of a fire in a tunnel. The results of such the process are then evaluated on a real world case study from Lochkov tunnel near the city of Prague.

Driving is the most universal and ordinary task people perform every day and in the same time the most complex and dangerous. It requires a full range of sensory, perceptual, cognitive, and motor functions, all of which can be affected by a wide range of stressors and experience levels. Therefore exploring of human behaviour while controlling vehicle is a crucial task in improving traffic safety. Experimental studies can always be conducted with on-road tests, however using a simulator is safer and more cost effective. The main goal of this paper is to demonstrate if, and under what conditions, driving simulator provides results sufficient to provide insight to the behaviour of drivers. It discusses its limits and advantages. Overall, the researches reviewed in this paper indicates that simulator driving behaviour approximates (relative validity), but does not exactly replicate (absolute validity), on-road driving behaviour.

This paper deals with the changeover from the decision tree (bivalent logic) approach to the fuzzy logic approach to highway traffic control, particularly to variable speed limit displays. The usage of existing knowledge from decision tree control is one of the most suitable methods for identification of the new fuzzy model. However, such method introduces several difficulties. These difficulties are described and possible measures are proposed. Several fuzzy logic algorithms were developed and tested by a microsimulation model. The results are presented and the finest algorithm is recommended for testing on the Prague City Ring Road in real conditions. This paper provides a guidance for researchers and practitioners dealing with similar problem formulation.

The outputs of many large EU research projects that are aimed at improving life in cities and that of their residents, such as those funded under the Horizon 2020 programme, are often delivered by technology-oriented partners or research institutions that, although they are often a part of a heterogeneous consortia, may not be aware of the real-life dimension of the problem they are solving. This could be particularly troublesome in case a holistic solution should be delivered and is especially valid in case of Smart Cities related problems. In this paper we are proposing a methodology to overcome this issue while using the example of a real Horizon 2020 project MAVEN – Managing Automated Vehicles Enhances Network. The methodology is based on the system engineering approach and its application is illustrated on the first MAVEN stakeholder consultation workshop including its evaluation using the online tool Mentimeter. The proposed template can be used in other EU projects.

Satellite Earth remote sensing data are widely used in Smart Cities in various areas, such as energy industry, transportation area, or disaster monitoring. Real time remote sensing data from some region could help to parry various extraordinary (emergency) situations (forest fires, floods, emergency situations on roads, etc.). It could be used in control centers to support decision making able to promptly inform citizens about current situation. In order to have the actual data, it is necessary to perform Earth observations as soon as possible after an emergency situation arises. But before the data from a satellite can be provided for its processing, a number of tasks must be solved. One of such tasks is changing a schedule of tracking, telemetry and command (TT&C) ground stations to carry out a communication session with remote sensing satellite for sending on it program of target equipment work (to observe the region and downlink sensing data to receiving ground stations). In this paper, the authors propose approaches to increase the efficiency of changing a schedule of TT&C ground station in order to increase the efficiency of getting satellite remote sensing data. Such issues as organization information exchanges between subscribers, prompt notification of planning department specialist about changing the current situation, increase efficiency of including in schedule additional communication sessions, the informative representation of data about current situation are discussed. The proposed approaches can increase the efficiency and reasonableness of the decision making in control centers to parry various extraordinary (emergency) situations. In turn, it can make cities more sustainable and safe, in other words smart.

Crowdsourcing is one of the most fundamental elements in so called sharing economy. This type of economy enables sharing of unused resources in the community, which is a key concept in Smart City initiatives. This paper focuses on the field of crowdsourced logistics, where many startups have emerged in the last years. Also companies, which provide other crowdsourced services, such as Uber, are often creating their logistics spin offs. However there is no well-known market leader yet. The aim of this paper is to find common key denominators of the most successful crowdsourced logistics companies. It should provide a lead to nascent companies and future research, where to pay attention. Crowdsourcing started to be studied after 2006 when the term was first used. Nowadays papers about this topic are appearing more frequently. However there has not been a clear comparison of crowdsourced logistics companies according to their revenues and raised funds. Such research can help future companies to identify the most important key features to cover.

Technology has undergone rapid development in the past several decades and we are now at a point where many technologies are available to help create smart cities. Many technology companies and research institutions as well as political organizations are currently discussing this field with the highest priority. One can say that the biggest challenge to smart cities is not technologies themselves, but the merging of all available technologies into one symbiotic unit that fulfills the expected objectives. Smart cities are about connecting subsystems, sharing and evaluating data, and providing quality of life and satisfaction to citizens. We have various models of transportation systems, optimizations of energy usage, street lighting systems, building management systems, urban transport optimizations, however currently, such models are dealt with separately. In this paper, we provide an overview of the smart city concept and discuss why Multi-agent systems are the right tool for the modeling of smart cities. The biggest challenge is in connecting and linking particular subsystems within a smart city. In this paper, a modeling of a smart city building blocks is provided and demonstrated with one particular example -- a smart street lighting system. Focus will be on the decomposition of the system into subsystems as well as a description of particular modules. We propose to build models and since each individual entity can be modeled as an agent with its beliefs, desires and intentions, we suggest using Multi-agent systems as a tool for modeling systems` connections within the smart city and assessing how best to use the data from those systems.

Jedním z trendů 21. století v oblasti elektronických produktů a informačních technologií je jednoznačně připojování jednotlivých zařízení do internetu a jejich vzdálené monitorování a ovládání. Taková zařízení jsou většinou označována anglickým slovíčkem smart, které do českého jazyka nejčastěji překládáme jako chytré. Do všeobecného povědomí se tak dostávají označení jako chytré město, chytrá ulice, chytrá budova, chytrá televize, chytrý termostat, chytrá lednička nebo dokonce chytrá žárovka. Odvrácenou stranou, o které se zatím příliš veřejně nemluví, je kybernetické zabezpečení těchto zařízení proti útokům hackerů z internetu.

There are currently presented ”smart city” solutions from the biggest worldwide corporation through start-ups up to the universities. It is indisputable that some of them are for sure very interesting and beneficial for citizens and cities themselves. Nevertheless, there are too many provided solutions that make it very hard to evaluate which are really beneficial and which are not. A simple and understandable framework that would allow cities to evaluate a proposed smart city solution is currently missing. The aim of this paper is to provide an approach for evaluation of particular smart city solutions and to determine whether it is suitable and beneficial for the city. Cities are dynamic, non-linear, complex systems and the evaluation cannot be done by static and deterministic program in most cases, but dynamics and non-linearity of cities must be considered. While modeling is widely used in transportation or energy management, in the field of smart cities, no modeling approach has been used. In this paper, SMACEF (SMArt City Evaluation Framework) is proposed and its contribution is shown on a case study.

One of the basic ideas in the field of smart cities is inter-connectivity. Proposed solutions must put together solutions from different fields (sensors, transportation, economy, legislation, energy, IT and many others) and integrate them in order to serve the citizens needs and to ensure sustainability. Additionally this is not done once by buying certain technological tools, but it must be an ongoing process. Thus, not only technological view, but also social aspects must be integrated into services aiming on improvement of the quality of life and sustainability. This is in general a very difficult task, not addressed well by existing methodologies or real world projects. In this paper, we propose a solution to this problem. First, we propose an alternate way of demonstrating the expected outcome of a solution for smart cities. It aims at addressing scenarios from the perspective of the end users rather than ”just” providing an overview of technology and its capabilities as it is mainly done in the technological companies serving as a solution provider. While this is a small change, it has big effect from the customer (municipality) perspective as they can better support the effects on the end users. Second, this paper demonstrates SMACEF - SMArt City Evaluation Framework. This is a modeling tool suitable for evaluation of Smart City Initiatives. On an example of an important square (Charles Square) in Prague, the capital city of the Czech republic, certain buildings blocks, and their interconnections and the possible effects are discussed.

The paper attempts to explain the impacts of large transport structures on the traffic quality and urban environment, in terms of the sustainability of these structures in the long term decades. Such effects can be expressed e.g. via travel time and speed, the length of congestions and time delays, number of stoppings, fuel consumption, location and amount of pollutants produced. The rating is based on the application of mathematical models working with data measured throughout the city, using strategic detectors and floating cars, or test drives. One of the models is the estimation of fuel overconsumption due to reduced travel speed e.g. in congestions, as well as a model determining the delay costs due to traffic situation. Models and measurement data enable to compare the situation before the construction and after implementation of the structures. The method is demonstrated in the case of the Blanka tunnel complex on City Ring Road, which was opened in September 2015.

In this paper, a pragmatic and goal oriented system for risk analysis in road tunnels is described. It is particularly focusing on mortality risks in case of a road tunnel accident. It is a deterministic approach combining three major components: a) vehicle distribution in a tunnel; b) smoke propagation in case of a fire; and c) people evacuation (escape) component. The major improvement of this approach is in capturing the knowledge often provided only by experts into a robust and pragmatic system available to all decision makers. This is achieved through a large number of scenarios combining different configurations of road tunnels (e.g. different number of lanes, different speed limits) and the travel demand (e.g. different structure of the flow, different volumes of traffic) which were prepared and evaluated through microscopic traffic simulation. The resulting scenarios with the information about the number of vehicles in different tunnel sections were obtained. The results describe most of the existing tunnels and situations and can be used universally. Similarly, the people evacuation component can be evaluated in a general form. The results can be manually updated to suit any particular road tunnel which can differ for example by the availability or quality of warning and information systems. The remaining task is to create a physical model of the real tunnel and to model the smoke and fire propagation. All these components were combined into the CAPITA software that was developed as a part of the research project HADES (supported by the Technology Agency of the Czech Republic). The CAPITA software is presented in the last chapter of this paper. The scenarios available off-line are in fact a knowledge base available to experts as well as decision makers and lead to a higher level of comprehension of the developments in case of fire and significantly speed up preparation of a risk analysis.

An important part of the smart cities of the future are surely autonomous vehicles as they have a direct effect on the quality of life of its citizens. The possibility of deployment driverless vehicles introduces not only possible improvement of safety due to limitation of human errors, but also a potential utilization of unoccupied cars. This paper describes principles of operating and applicability of one of the technologies allowing the operation of autonomous cars - the Lane Assistant System (LAS) in conditions of the Czech Republic. The properties of road markings on road network were measured on the D5 motorway. Furthermore this information were compared with the data acquired from CAN bus about activation and parameters of LAS in an instrumented vehicle. Finally, suitability analysis was performed to estimate future applicability of such system on the tested roads.

This paper focuses on an important topic – on evaluation of various transport structures. It is a typical situation that a decision maker must choose from various alternatives and with respect to different, often contradicting criteria. In this paper, a method adopted from the field of risk management, SAFMEA, was adopted. This is a novel approach that however introduces statistical evaluation of expert feedback to provide a robust decision support materials. Here, in a structured way, the expert know how is extracted and processed. In this approach, not only average aggregate values are evaluated. An important contribution of this approach is in looking into the variances in the answers from particular experts in order to capture the consensus or the lack of it. The method was validated on a case study from the Czech Republic, particularly on evaluating four different approaches to modernization of a highway D1. The method provided a recommendation that has been as a result actually implemented by the ministry of transport. The results confirm that the approach is worth consideration.

Smart City is a phenomenon of the last years with a lot of researches been conducted in the past. Smart City is an interdisciplinary field and requires a high level of cooperation among experts from different fields in order to achieve the best results in the six key areas: economy, environment, mobility, people, living, and governance, with the contribution of the latest technologies. Following a system development methodology is in general a necessity for a successful implementation of a system or a project. Smart City projects introduce additionally new challenges. There is the need for cooperation across many fields, from the technical or economic through legislation to humanitarian, together with sharing of resources. The traditional system engineering methodologies fail with respect to such challenges. This paper provides an overview of the existing system engineering methodologies and their limitations. Next a new, so called Hybrid-Agile approach is proposed and its advantages with respect to the Smart City projects are discussed. The approach however expects change of our thinking. The customers in a Smart City projects (typically municipality or governmental organizations) must become active and engaged. It is demonstrated, that a city cannot be smart without Smart Government.

In this paper, we propose the conjunction of the Smart City Initiative and the concept of Industry 4.0. The term smart city has been a phenomenon of the last years, which is very inflected especially since 2008 when the world was hit by the financial crisis. The main reasons for the emergence of the Smart City Initiative are to create a sustainable model for cities and preserve quality of life of their citizens. The topic of the smart city cannot be seen only as a technical discipline, but different economic, humanitarian or legal aspects must be involved as well. In the concept of Industry 4.0, the Internet of Things (IoT) shall be used for the development of so–called smart products. Sub-components of the product are equipped with their own intelligence. Added intelligence is used both during the manufacturing of a product as well as during subsequent handling, up to continuous monitoring of the product lifecycle (smart processes). Other important aspects of the Industry 4.0 are Internet of Services (IoS), which includes especially intelligent transport and logistics (smart mobility, smart logistics), as well as Internet of Energy (IoE), which determines how the natural resources are used in proper way (electricity, water, oil, etc.). IoT, IoS, IoP and IoE can be considered as an element that can create a connection of the Smart City Initiative and Industry 4.0 – Industry 4.0 can be seen as a part of smart cities. Interconnection of these systems can be expected to change -transport processes from design logistic processes through to their online optimization with respect to the chosen objective function and the latest information from the transport infrastructure. Linking information from process-based Industry 4.0 with intelligent transport systems of the smart city could create very effective, demand-oriented and higher productivity of manufacturing enterprises as well as sustainable development of society.

Nowadays, the term smart city is often used as a selling argument for projects. Unfortunately, it is often degraded to a simple use of advanced technology. However, it was demonstrated in several scientific publications as well as for example in Amsterdam city that the citizen’s quality of life shall be one of the main objectives in any smart city project. In order to enhance this topic, we provide a clear view on the implementation of smart city projects from the citizen’s perspective. In this paper, we first describe the importance of citizen’s participation and different forms of such participation in different smart city project phases. Two case studies are presented as well to demonstrate the benefits of participation in municipal projects. Additionally, we propose a formal solution to this topic. In general, Systems Engineering methodologies are used in order to ensure the right project outcome. There are different methodologies, mostly adopted from the information technology field. Unfortunately, they focus mainly on the relation between a customer (in the case of smart cities it is typically a municipality) and a solution provider. They also do not take into account the new challenges which occur in smart city projects, such as focus on interdisciplinary teams, sharing of resources, or even involvement of citizens. In this paper we enhance this topic by demonstrating how a Hybrid-Agile Methodology (HAM) can used to involve citizens in the different project phases. This is certainly a novel approach not addressed by the current methodologies and not properly addressed in smart city projects. It has been mentioned several times that we cannot have a smart city without smart citizens.

This paper focuses on an important topic – estimation and prediction of pollutants in road tunnels as an input for ventilation control systems. It demonstrates that using estimated pollutants level computed from traffic data is not only possible, but even introduces diverse advantages. Next to the ability to predict future values of the pollutants level, lower investment costs (installation of rather costly pollution sensors is not needed any more) and lower maintenance costs (minimizing costly turning on and off of the ventilation system) must be mentioned. Two different methods based on regression models and decision trees are presented and their results compared in this paper. The developed models were evaluated on data from tunnel Mrazovka located on the Prague city ring. The results clearly confirm the suitability of the proposed solution for given task.

In the last 30 years, there is visible trend of performing traffic experiments with use of Driving Simulator. As an example of such studies we can name researches focused on driver behavior in various traffic situations where safety and economic concerns significantly limit use of naturalistic driving studies. An inherent part of such experiments is proper design and implementation of experiment scenario, including surrounding traffic. In the following paper, the authors describe and compare the key properties of three most common approaches to the generation of surrounding vehicles for the needs of driving simulator experiments.

Anglické slovní spojení Smart City se posledních několik let skloňuje ve všech možných směrech a patrně každý z nás se s ním již v nějakém významu shledal. Na zahraničních serverech existuje velké množství různých publikací, které se zabývají právě touto problematikou. Bohužel v českém jazyce dosud neexistuje ucelený přehled o současném stavu v tomto velmi mladém oboru. Tento úvodní článek si dává za cíl čtenáři osvětlit pojem Smart City a seznámit jej s obecným konceptem a motivací pro jejich vznik. V návaznosti na tento článek vyjdou další pokračování, která se budou podrobněji zabývat jednotlivými aspekty publikovanými v tomto článku. Samotný termín Smart City vznikl v průběhu 90. let ve Spojených státech. Existuje několik dalších termínů, např. „Digital City“, „Inteligent City“, „Information City“, které v podstatě nazývají jiným způsobem to samé, co se skrývá pod označením Smart City. V českém překladu se tento termín překládá jako chytré město.

Many previous studies have confirmed the strong relationship between speed compliance and the frequency and severity of traffic accidents. Variable speed limit (VSL) system as a measure to improve traffic safety enables the freeway system to change its posted speed limit based on various traffic and environmental conditions. Such system helps drivers to recognize the upcoming events, to adjust their driving style and in such way to address speed variation of the traffic flow. This is called speed harmonization. Although many studies researching the effect of VSL system on the traffic stream can be found, there are only few addressing its influence on the drivers behavior, particularly focusing on their tolerance limit and compliance, which has crucial meaning for future design of controlling algorithms. This study was prepared to inspect this grey area by studying the data from the VSL system at Prague city ring, describing the influence of the highway management system and its influence on drivers.

A smart city is characterized by its ability to integrate people, technology and information to create a sustainable and resilient infrastructure that provides high quality services for residents. Transforming a city into a smart city requires collaborative efforts between government, industry, practitioners, residents and researchers. This paper describes how researchers in a recently formed consortium of three universities are developing a smart cities innovation network, with an emphasis on smart mobility, smart buildings, and smart bridges. The consortium is applying a semantic-based approach to address the initial challenge of building an effective interdisciplinary network of university researchers located in different parts of the world, in three cities with different sizes and stages of economic development.

Mnohé předchozí studie potvrzují silný vztah mezi dodržováním rychlosti a frekvencí dopravních nehod (či závažností dopravních nehod). Systém Proměnného omezení rychlosti (VSL) je nástrojem ke zlepšení bezpečnosti silničního provozu, který umožňuje změny rychlostního limitu na základě stávajících jízdních podmínek. Na základě automatické detekce událostí dojde k přizpůsobení rychlosti jízdy - tedy k harmonizaci rychlosti. V současné době je v České republice první VSL systém instalován na Pražském městském okruhu, a to s cílem zvýšení bezpečnosti a pozitivního ovlivnění dalších parametrů dopravního proudu. Ačkoli můžeme nalézt mnoho studií, které se zabývají vlivem VSL systému na dopravní proud, existuje však jen velmi málo odborných prací, které popisují vliv na chování řidičů, zejména se zaměřením na toleranci a dodržování rychlosti. Přitom má tato informace zásadní význam pro návrh budoucích algoritmů VSL. Tato studie byla vytvořena za účelem popisu problematiky, jež ukazuje vliv liniového řízení dopravy na chování řidičů.

Highway management systems are used to improve safety and driving comfort on highways by using control strategies and providing information and warnings to drivers. They use several strategies starting from speed and lane management, through incident detection and warning systems, ramp metering, weather information up to, for example, informing drivers about alternative roads. This paper provides a review of the existing approaches to highway management systems, particularly speed harmonization and ramp metering. It is focused only on modern and advanced approaches, such as soft computing, multi-agent methods and their interconnection. Its objective is to provide guidance in the wide field of highway management and to point out the most relevant recent activities which demonstrate that development in the field of highway management is still important and that the existing research exhibits potential for further enhancement.

Smart city covers a wide range of topics. In this paper, we introduce a basic building block able to address already on a fundamental infrastructural level several of the key user functions of a smart city. This is done on a scale that can be rather easily managed. So called “smart street” is defined and introduced as a basic building block for any smart city architecture. It does not focus on transportation only (for example through signal control and management), it covers also other aspects, such as data connectivity, safety of citizens, energy consumption and many others.

The term Quality of Life is essential in understanding the outcome of smart city initiatives. According to several definitions, it is one of the major objectives of activities in the area of Smart Cities. Different studies presented in this paper aim at classifying a city with respect to “smartness”. The results of all such studies however look at a general index. As discussed in this paper, quality of life is highly individual. It is not true that one measure has the same impact on the quality of life of different individuals. To understand perception of all individuals within a city is difficult but necessary, if we want to model the impact of different measures on different groups of citizens. In this paper, the authors propose a way to gain understanding on the issue of individual perception of Smart Cities. This supports the researchers not only in modeling efforts, for example using multi-agent systems, but also in selection of projects. First, so-called life stages (life cycles) are defined to address the individuality in perception. Next, an IPSCS survey is designed and mathematical tools for survey evaluation are proposed to allow for learning more about such perception. In this paper, a survey was conducted to proof the proposed concept and methods.

Společenský význam role manažerů v byznysu roste tak, jak roste význam jejich pivotálního postavení v trojúhelníku zájmů vlastníků, zaměstnanců a zákazníků. Napětí v uvedeném trojúhelníku roste nebývalým tlakem vlastníků na co nejrychlejší a největší dividendu, tlakem nových generací zaměstnanců na zohledňování jejich požadavků na work-life balance, často při poklesu jejich výkonu i kvality práce, a nebývalou konkurencí na trhu a bojem o zákazníka. Manažerské „řemeslo“, které se lze naučit, je v současné době zmapováno a široce popsáno; k dispozici je celá řada známých postupů a best practice. Problém však spočívá ve schopnosti jejich aplikace v konkrétních případech, neboť každý doporučovaný postup či každý vybraný úspěšný případ jsou vázány na zcela specifické vnitřní a vnější podmínky firem, a proto nejsou zcela přenositelné. Rozhodující schopnost manažera spočívá právě ve výběru, pro jeho situaci, nejvhodnějších postupů a metod a ve flexibilním způsobu jejich aplikace. Manažer dneška musí být nejen leader, ale i vizionář, který je schopen anticipovat jak možnosti budoucího technického a technologického rozvoje, tak především budoucích požadavků trhu. A k tomu je potřeba mít hluboké znalosti o zákonitostech vývoje společnosti. Manažerské rozhodování je umění a obsahuje racionální i intuitivní komponenty a určité rozhodovací činnosti. Přes všechny dílčí i obecnější prognózy vývoje fenoménu business intelligence v kontextu manažerského rozhodování je vysoce pravděpodobné, že kreativní lidský činitel, zejména pokud jde o strategické rozhodování, zůstane nenahraditelný.

In this paper a new pragmatic framework covering the different challenges of smart city initiatives is provided. The authors build a theoretical foundation and formulate its consequence i.e. the needed shift from the traditional perspective into new research directions. There are many research projects addressing the different aspects of smart city initiative. The authors aim on further enhancement of this framework, to suit directly the different projects from the real life while maintain the theoretical soundness. Additionally, multiagent systems are proposed and discussed as the approach able to address the different constraints and challenges.

In this paper we discuss the paradigm shift that has to be understood by the decision makers as well as societies in the field of transportation. It is not sufficient to focus only on mobility as the current strategies do, but we need to look at citizens quality of life as whole. It is affected through different aspects, and only one of them is transportation. We need to provide a better way to participate in activities - increase accessibility of goods and services. This cannot be done with look at transportation only. We need to understand the entire organism of a city. This has been recently understood by the Smart cities initiative. A smart city is defined within this paper as an alliance system, i.e. a system where particular subsystems use the common resources in a synergic way. In order to make this concept work, an objective function following the above mentioned principles must be provided. In this paper, we offer entropy of a city as a promising candidate for such objective function.

The development of highway management systems is a current topic in the Czech Republic. At this moment, three generations of highway management systems can be delimited. The first generation laid the foundations for further development and is based on the common rule based approaches. The second generation, which is nowadays being developed, represents an improvement and extension of the first one introducing fuzzy logic. The third generation is a question of a future development. The authors believe that the multi-agent systems represent a promising approach. Thus, the basic principles, advantages and reasons for the application of multi-agent systems for highway management are respectively treated and discussed.

In this paper, the authors provide a discussion about technological systems in road tunnels and their effect on the overall time needed for people witnessing a fire to escape. Prompt identification of a fire, together with an optimal deployment of relevant information to the trapped people significantly increases their awareness and reduces the response time, thus speeding up the entire evacuation process. The fire identification and warning systems are in nature heterogeneous technological systems, composed of different sensors and actuators. The major objective of this paper is to introduce a methodology of assessing awareness and response times in relation to such heterogeneous technological systems. The resulting estimated time does not only refine a scenario oriented risk analysis, but also optimizes the design as well as the price of the systems installed in a real particular tunnel. The theoretical foundations are also applied by the authors in a fuzzy evaluation system – CAPITA, which is also briefly described in this paper.

Traffic telematics systems have been used to increase road capacity as well as safety. On highways, this is accomplished with the usage of so called highway management systems, which among others through speed harmonization, ramp metering, informing about weather conditions or danger on road addresses these issues. Such system was recently implemented for the first time also in the Czech Republic. In this paper, the results from the first months of operation will be provided. First, the expected theoretical effects of such system on traffic flow characteristics will be provided and discussed. These effects follow the theoretical foundations of traffic flow theory, represented for example by fundamental diagram or changes to road capacity due to speed harmonization. Based on the measured data, the results of the particular implementation in the city of Prague, Czech Republic will be provided. The results will be discussed and compared to international experiences.

Highway management systems belong to modern methods enhancing capacity and increasing safety on highways, while using strategies such as variable speed limits, ramp metering, information about alternative routes or danger on road and others. Typically, they use static infrastructure, i.e. fixed sensors and gantries with variable message signs, which are not very effective in case of constructions. In this paper, a mobile telematics system (mRLTC) aiming on enhancing the common static highway management system in work zones is presented. Its objective is to inform drivers about the traffic situation ahead and warn them in case of traffic instability. This is essential primarily to increase the safety on roads and secondly also the driver’s comfort. The system, its major components and the different modes of operation are presented as well. In order to be able to place the system into operation under real world conditions, an evaluation within microsimulation environment has been performed for an existing work zone on the major Czech highway, D1. In this way, the algorithms and settings of the system can be optimized and its performance and effect on traffic can be determined for different traffic scenarios without any disruption to traffic. The simulation process and its results are discussed within this paper as well

Fuzzy logic has been a popular tool to address advanced control tasks lately. This is true even in transportation, where it has been used for tasks such as ramp metering, control of traffic lights as well as, for example, within highway management. In this paper, we demonstrate that PTV VISSIM can be used for the evaluation of advanced control algorithms, even without usage of API. In this way, even without knowledge of classical programming languages such as C ++ or Java, any fuzzy control algorithm can be implemented directly in the microsimulation tool and its effect on traffic directly evaluated.

In this paper is demonstrated, how a fuzzy control system can be implemented and verified directly in a microsimulation tool from the company PTV, VISSIM. A new fuzzy algorithm for speed harmonisation is developed and its implementation is explained in details. The main advantage of this solution is in the direct implementation of the control algorithm in the microsimulation tool without the need to deal with an API and external software. Additionally, the configuration and optimisation of the control algorithm is performed quickly in the tool and directly responds to the microsimulation results. This has an impact on the time to implement such a solution as well as the overall cost, since a single resource able to work with the microsimulation tool can do the work and no programming experience are required.

Aby bylo možné ověřit kvalitu nových algoritmů LŘD před vlastní implementací a nebylo nutné testovat nové algoritmy na reálné dopravě (což je zjevným bezpečnostním rizikem), je třeba vytvořit simulační dopravní model. S ohledem na úroveň detailu, nutnost zahrnutí chování jednotlivých řidičů (např. reakce na informaci na informačních tabulích o snížení maximální povolené rychlosti) se bude jednat o mikrosimulaci dopravy. Vzhledem k tomu, že mikrosimulačních systémů existuje celá řada, součástí řešení bude i výběr konkrétního SW nástroje splňujícího požadavky na projekt.

This book covers an important topic from the field of intelligent transportation systems - highway management and control. It introduces a concept of highway viewed as a controlled system and describes the significant features from the superordinate control theory. Next, a modular control system is proposed, which follows the theory described above and aggregates interdisciplinary research into one advanced management system. The proposed structure can be used in different scenarios and enables optimal usage of particular modules. The proposed modules are described as part of the next section and for each, author's experiences are used to demonstrate its focus. Finally, the next steps and author's future research are described to demonstrate the long term validity and usability of this original concept.

Electronic payment for using road infrastructure is gaining importance in the realm of intelligent transportation systems (ITS). While preparing such an electronic fee collection system, the level of enforcement needed must be determined. This is not a trivial task, because it is affected by many technical and monetary factors. At the same time, it cannot be expected that all decision makers are deeply involved in this field and are able to make an optimal decision depending on the recommendations of external experts. This paper describes a fuzzy expert system for determining the optimal level of enforcement-FESOLE. It bridges a missing part in the research concerning ITS. A fuzzy expert system is used to approach this problem. It can extract and exploit the knowledge of human experts and convert it to a robust computational model.

Systémy liniového řízení dopravy doposud nejsou v podmínkách České republiky instalovány, a přestože je několik projektů s tímto zaměřením v přípravě, neexistuje metodika pro identifikací excesů ani požadavky na algoritmy řízení. Výzkumná zpráva naplňuje poslání projektu pro rok 2009. V úvodu byly popsány metody pro management dálnic, jejíchž je liniového řízení důležitou součástí. Pro aplikaci v zahraniční používaných algoritmů do tuzemských podmínek je důležitá část popisující situaci na komunikacích v ČR. Následuje dokumentace výzkumu metod sběru dopravních dat na dálnicích, v zahraniční používaných algoritmů a jejich zhodnocení. Výzkumná zpráva popisuje také algoritmy pro řízení provozu pomocí systému liniového řízení dopravy a navrhuje základní postupy pro jejich uplatnění v ČR. Výstupy této zprávy budou použity v následném roce jako podklady pro modelové ověření na konkrétním úseku dálnice v ČR.

This work aims to propose an algorithm that belongs to the field of activity-based approaches to travel demand analysis. Its objective is to simulate individual's daily activity-travel patterns, and to incorporate the interactions among members of particular household. This model uses several tools to simulate the activity patterns. A lot of effort has been dedicated to cluster analysis of activity patterns. The methodology has been studied and an approach that suits this problem is suggested. Decision trees, particularly the CHAID algorithm, are used to take into account the personal and household characteristics. The individual's daily activity patterns that carry information about activity participation on a detailed temporal scale are the output of this model. These patterns respect individuals' constraints that are implicitly embedded. The model was evaluated using data from the Centre County, Pennsylvania that were collected during fall 2002 and spring 2003.

A new system for deployment ITS standards to the praxis which is end user oriented ha been developed in the frame of STANDARD project. It provides more than just a known search engines. This approach is based on so-called semqantic web which basically adds meaning to data, so that it can be processed by human as well as machine agents. This mechanism is described in the following part of this paper. The secont part is dedicated to real application to standards and describes practical directions how to start with implementation of the proposed method.

This paper provides a very brief introduction to computational intelligence and its application to transportation. The paper complements the many interesting reviews of existing literature and applications, such as in Teodorovic and Vukadinovic, 1998; and Avineri, 2005. This paper has different objectives. It provides guidance for transportation practitioners who are facing real word problems and are interested in applying nowadays popular methods from the field of artificial intelligence or soft computing. It provides a short introduction to this field and basic overview of the theory behind these methods. The major focus of the presentation is on showing the strong and weak points of each of these methods and a proper application field.

Transit of heavy, especially overloaded trucks is a problem in many countries. It is true also for the Czech Republic. This is proven, for example, in a feasibility study prepared for the ministry of transport, CR [1]. For this reason, so called weight in motion (WIM) systems become today justly quite a lot of attention. The major objective of this paper is though to introduce the concept of weight in motion. Rather than discussing the principles of WIM, the reasons for such systems are provided and their need justified. Another important objective is to discuss possible usage of WIM systems within the scope of Intelligent Transportation Systems (ITS), with focus on EFC systems. The name WIM refers to systems, which automatically measure weight of passing vehicles without the need for stopping them. However, nowadays it is not generally true. In most projects, the WIM system does not ensure sufficient precision to provide exact weight measurement. Rather, it is used to detect potentially overloaded trucks, which are then asked to stop for a stationary check.

Electronic fee collection (EFC) systems require knowledge of vehicle category in order to determine the fee. An automated classification system is always needed. In this paper such classification system is introduced. The input data of such system measured in real conditions on a highway are analyzed and their relationship to the resulting vehicle classes is demonstrated. This analysis is very important since it helps to find a proper modeling tool. The modeling tools recommended for such application, together with result of a decision tree model are provided as well. Our major objective is to discuss all core topics related to vehicle classification and provide guidance in the first steps of preparation of such system.

Even though activity-based approaches to travel demand analysis have gained increasing attention in the field of transportation planning, there are still many topics that require further study. An important issue with respect to understanding the decision making process in activity scheduling is the study of interactions among members of a household. It has been recognized in the literature that models belonging to this filed should reflect these interactions. This paper addresses the question what is a recommendable representation of the within-household interactions in activity patterns? Six different representations of these interactions are provided and compared in this paper. In order to provide a numerical evaluation, a microsimulation model, which is also briefly described in this paper, is used.

V České Republice v současné době probíhá příprava na vybudování systému pro výkonové zpoplatnění komunikací, tzv. elektronického mýtního systému. Existuje řada technologií, které se mohou pro takový systém využít, ale v tomto příspěvku o jejich výhodách či nevýhodách diskutovat nebudeme. Hlavním cílem je popsat dohledový systém, který je součástí každého systému pro elektronický výběr mýta. Článek se věnuje jeho hlavním modulům a komunikaci mezi nimi. Zvláštní důraz je kladen na zajištění bezpečnosti a ochrany dat. Jsou využity zkušenosti společnosti ELTODO dopravní systémy, s.r.o., která vybudovala na pátém kilometru dálnice D5 v Rudné u Prahy zkušební portál, kde v současné době probíhá intenzivní testování dohledového sytému v podmínkách reálného provozu na českých silnicích.

The complicated traffic situation in Prague is not only due to a rise of the number of cars in the last few years, but also due to historical formed streets which are not able to fully satisfy present traffic performances. Also the ratio of motorization is higher here than, for example, in Vienna or Cologne. Using standard methods cannot solve the enormous traffic problems - a new approach should be used.

V tomto příspěvku představujeme dohledový systém, který byl vyvinut pro potřeby elektronického mýtného v České Republice. Společnost Eltodo dopravní systémy postavila na pátém kilometru dálnice D5 ve směru na Prahu portál a osadila ho potřebnou technologií. Jedná se o modulární systém, jehož velkou výhodou je, že není vázán jen na jediné řešení elektronického mýtného systému. To znamená, že je zcela autonomní a má přesně nadefinovaná univerzální rozhraní. Je plně automatický a mimo jiné obsahuje moduly pro automatické rozpoznávání registračních značek vozidel, klasifikace typu vozidel, čtení obsahu palubních počítačů (On Board Unit) či komunikace s centrální databází. Cílem této prezentace je demonstrace jeho základních hardwarových modulů a logických funkčních bloků, společně s praktickými výsledky. V neposlední řadě zde diskutujeme i možnosti dalšího využití či rozšíření popsaného systému.

In this paper a methodology for developing of a microsimulation model of individual's daily activity-travel patterns is presented. The model outputs are the individuals' daily activity patterns on a detailed temporal scale. It is innovative in the way it deals with constraints. It was developed in order to fill in the gap in existing research, where majority of models cannot easily be used in praxis. This approach is rather simply and straightforward and suiting the needs of practitioners.

Activity-based approaches to travel demand analysis have gained attention in the past few years and rapidly created the need to develop alternative microsimulation models for comparisons. In this paper, one such example simulates an individual's daily activity-travel patterns and incorporates the interactions among members of households. This model uses several tools to simulate the activity patterns, including a new method to extract activity patterns from data and decision trees to take into account personal and household characteristics. The model outputs are the individuals' daily activity patterns on a detailed temporal scale. These patterns respect individuals' constraints, which are implicitly embedded in the simulated activity and travel schedules via the intrahousehold interactions. This model was evaluated with data from 1,500 persons in Centre County, Pennsylvania, collected during fall 2002 and spring 2003.

n this article, the relationships among technology ownership and availability, Advanced Traveler Information Systems (ATIS) awareness, and ATIS frequency of use are examined. The four main media considered are the Internet, television, radio, and telephone/other. Awareness and use of ATIS through the four media considered here are different for different users. They also change as household and person characteristics change over time. Since Information and (tele)Communication Technology (ICT) adoption is changing rapidly, this has a significant positive effect on Internet-based ATIS but not a clearly negative effect on all other media. The relationship between awareness and use appears to be nonlinear and dependent on the medium considered. Evidence of substitution between television and Internet and enhancement among other media were also found in this study.

The main objective of this workshop is to provide an overview of methods that belong to the field of computational intelligence and their suitability for transportation planning and modeling. The following methods will be addressed by this workshop: Fuzzy Logic, Artificial Neural Networks, Adaptive Neuro-Fuzzy Inference Systems (ANFIS), and Genetic Algorithms. The basic principles of these methods will be described and their practical applications will be illustrated with examples. Often the methods of computational intelligence suffer criticism about their performance due to inappropriate use to problems that they are not meant to serve. This workshop will offer the strengths and weaknesses of each method and describe the appropriate problems for each. The workshop will focus mainly on applications to data analysis and data mining.

V cizích zemích došli k zjištění, že se v současnosti musí čelit otázce přilišného používání osobních automobilů v moderní společnosti. Má to negativní vliv na kongesci ve městách a ve velké míře i na životní prostředí. Proměna směrem k jiným možným způsobům dopravy jako je veřejná doprava, kolo, chůze nebo cestování autem s větším počtem pasažérů, by mněla být prioritou ve sféře dopravního plánování. Tento článek má za cíl demonstrovat důležitost této otázky a ukázat několik příkladů úspěšného aplikování proměny v cizích zemích.

A relatively new method for data analysis called the adaptive neuro-fuzzy inference system (ANFIS) is illustrated with an example from travel behavior modeling. The options offered by this data analysis technique are illustrated by using data from Australia. In addition, an experiment was performed to identify the optimal split of data into an estimation sample and a validation sample. Comparisons of ANFIS and the more traditional regression methods such as ordinary least-squares linear regression and negative binomial regression were performed by using the mean square error and correlation coefficients. ANFIS is shown to be a useful tool, and its further use in travel behavior research and applications in transportation planning is recommended. However, many additional issues require further scrutiny and experimentation, which are discussed.

The Center for Intelligent Transportation Systems within the Mid-Atlantic Universities Transportation Center at the Pennsylvania State University assisted the Pennsylvania Turnpike Commission in a study to understand how motorists and truckers on the Turnpike obtain and use travel information. To accomplish this goal, a mail-back survey was distributed to 5,510 motorists and 3,584 truckers on the Pennsylvania Turnpike between October 22, 2001, and November 7, 2001. A total of 1,528 (27.7%) motorists and 889 (24.8%) truckers returned completed questionnaires. Key findings of the study include: More than 50% of the motorists sought some type of travel information before making their trip. The most common types of travel information sought were traffic conditions, weather conditions, and route maps. Just over one-third of motorists used information provided by a variable message sign (VMS) during their current trip. In general, the motorists felt that the VMS displays were clearly visible and easy to read and understand, and that the information provided by the VMS was of good quality. The majority of motorists using the VMS would use VMS-provided information again.

Four critical aspects on the use and preferences for traveler information systems are examined in this paper. They are the type of information used by motorists, media used to seek and receive information, the importance ratings assigned to various types of information, and the perceived usefulness of the media in providing the information needed. Data from a survey conducted in 2001 on the Pennsylvania Turnpike aiming at assessing a variety of perceptions and information needs are used to study these aspects. In the survey two major groups of users, the private automobile drivers and passengers (motorists) and the commercial vehicle drivers (truckers), are engaged in a mail-back survey providing a rich amount of indications about their information and technology preferences.
