This publication focuses on the development of a regional system for monitoring and evaluating public bus delays in the Ústí nad Labem Region in the Czech Republic. The case study, through a questionnaire survey, addresses the issue of the value of time loss caused by delays in regional public bus transport in the Ústí nad Labem Region from both a societal and individual passenger perspective. The survey includes, in addition to opportunity costs, the necessity to use earlier buses due to uncertainty and the potential real financial loss of passengers, for instance, due to late arrival to work and p otential employer sanctions. Routes for the questionnaire survey were selected based on an analysis of the movement of the bus fleet to represent typical situations applicable to the entire bus transport network. The result is a financial evaluation of the losses caused by bus delays in relation to the number of passengers, the purpose of their journeys, and the value of their time. The findings reveal relatively high costs of time losses, which, when applying a co st benefit approach, allow for the return on larger infrastructure investments aimed at reducing these delays. The research results will contribute to the development of issues evaluating the economic efficiency of investments in transport infrastructure.

Autonomous vehicles remain a major topic in the automotive industry today, including assistance systems, cooperative communication, and other aspects that lead to full vehicle autonomy. This paper investigates vehicle autonomy with a focus on parking assistance. Along with a review of parking assistants, the paper presents a prototype parking assistant with an alternative distance display. The parking assistant prototype, compared to parking without an assistant and conventional parking assistant, was tested in a real-world experiment of a within-subjects study design. The user experience of the proposed distance representation was obtained, and the results indicated that the prototype parking assistant with an alternative distance display helps less experienced drivers get a better idea of the distance from the obstacle.

In recent years, the concept of smart cities, along with autonomous transportation, has emerged as a significant focal point for researchers, urban planners, and technological innovators. This growing interest is driven not only by technological advancements but also by the pressing need to address current urban mobility challenges such as congestion, air pollution, and the necessity to enhance road safety. Autonomous trams, as a pivotal element of intelligent urban transportation systems, offer a promising pathway towards more efficient, safer, and sustainable urban mobility.

Agricultural machines nowadays use advanced satellite guidance systems that allow not only autonomous parallel guidance of machinery on the field but also enable the control of agriculture implements based on the geographical location of the field. By using aerial photogrammetry images, it is possible to identify the spots of land that require chemical protection. This information can be used to create prescription maps for the control of specialised implements, allowing the identification of weed outbreaks that require herbicide for their elimination. Using spot-spraying technologies, up to 80% of the active substance can be saved compared to the current common broadcast strategy of applying it to the entire field. This technology automatically controls the sprayer nozzles on the booms only in the spots where it is needed. Using an Unmanned Aerial Vehicle (UAV) allows us to take a detailed picture of the ground. Two main possibilities exist for collecting imagery data with an RGB or multispectral camera. One of the key requirements is the appropriate resolution of the picture, which could be controlled by flying altitude. This paper focuses on comparing RGB and multispectral gathered data toward affected spot identification.

Protecting vulnerable road users (VRUs) remains an issue despite significant advances in the development of integrated safety, autonomous driving and cooperative environments. As part of accident/collision processes, the urban area of municipalities continues to constitute a risk environment with a relatively high frequency of serious injuries (VRU) even at relatively low speeds. In order to understand and increase road safety, it is necessary to analyse the causes of traffic accidents in more detail using video recordings, virtual reality (VR) and automated computer vision methods. The state of the art in the Czech Republic is limited due to the absence of high-quality and extensive data sets. This article constitutes a proof-of-concept solution for the digital reconstruction of selected accident/collision events in 4 cities of the Republic, specifically in Prague, Liberec, Česká Lípa and Jaromeř. It makes it easier to identify, parameterize and virtualize the results of a traffic conflict study and can provide input data for the testing and validation of sensors, interaction models of road users’ behaviour, and preparation of scenarios for a simulated environment; ultimately it reinforces prevention efforts.

This study explores the development and evaluation of external human-machine interfaces (eHMI) for communication between autonomous vehicles (AVs) and pedestrians. By employing advanced virtual reality (VR) simulations and leveraging behavioral data from 600 survey respondents, the research examines the intelligibility and effectiveness of seven eHMI prototypes. The experiments utilized eye-tracking and spatial analysis to measure pedestrian response to AV signals in realistic virtual environments. The findings emphasize the potential of LED strip-based communication interfaces, demonstrating their superiority in terms of visibility, clarity, and implementation cost. This research contributes to the broader field of artificial intelligence applications in transportation, with a focus on ensuring safety and trust in autonomous systems interacting with vulnerable road users.

The interaction between emergency vehicle drivers and surrounding road users is associated with risks. This study explored the application of geofencing to improve interactions between drivers and emergency vehicles to reduce the risk of collisions in high-risk scenarios. Two high-risk scenarios, an off-ramp collision, and an intersection scenario, were used in two driving simulator experiments with 64 participants in total. Half of the drivers received a geofence-based warning about the upcoming traffic situation. The results indicate that geofencing, when applied to provide warnings in specific locations, improves driver behavior. In the off-ramp experiment, all drivers who received a warning avoided the off-ramp and thereby avoided the collision site, whereas all other drivers took the off-ramp. In the intersection experiment, the warning led to earlier deceleration, allowing the emergency vehicle to pass safely and with minimal delay; whereas nearly half of those who did not get a warning failed to yield to the emergency vehicle. The drivers acted based on the warning they received, even when they had not yet seen the emergency vehicle. The findings suggest that geofencing can improve driver behavior by detecting emergency vehicles early and reliably, thereby improving traffic safety and minimizing delay for emergency vehicles on call.

This study aims to evaluate the viability of hydrogen fuel cell (FC) technology as a range extender in powered two-wheelers (PTWs), focusing on choosing efficient FC size and under a time-limited, constant power delivery FC control strategy. The analysis presented in this study sheds light on the feasibility of hydrogen FC technology as an alternative energy source for mobility applications. In this study, a 1D powertrain simulation model was created, which enables the efficient analysing of both fundamental and advanced behaviour of individual vehicle subsystems and control strategies, even at the early conceptual design phase. The simulation results show that hydrogen FCs are a promising technology for range extension in urban mobility.

Due to growing concerns about the climate change situation, an increasing number of restrictions are being introduced. One of them is the shift towards smaller and lighter vehicles that are less demanding to produce, operate, and subsequently recycle. These are specifically L6 and L7 vehicles (four-wheelers called quadricycles). In addition, even for these vehicles, there is an attempt to make their operation even more environmentally sustainable by introducing government regulations on the powertrain, which will have to be purely electric from 2035. However, the growing popularity of these vehicles has one major drawback: safety. In the framework of the urban electric vehicle project located at the Faculty of Transportation Sciences, CTU in Prague, from the already mentioned category, safety is one of the main topics we want to address. This paper discusses the passive safety of quadricycles and the role of FEM simulations throughout the design and development phase of vehicles. The main objective is to validate the main frame of the developed vehicle at an extensive range of impact velocities. In this way, the behavior of the proposed front crumple zone design and their roles in frontal impact can be determined. The metrics to be monitored are, for example, the maximum accelerations on the structure in each part of the frontal crumple zone or the preservation of the survival space.

CTU strives to be a leader in education, research and innovation, inspiring students, academics and the wider community to actively engage in building a sustainable society. The University aims to be an institution that creates conditions for innovative approaches, promotes the protection of the planet, and provides a space for professional and personal development of individuals. Each of the fifteen thematic areas contains 3-6 goals, which were defined through analysis and discussion in working groups across the CTU. Fuller's method of pairwise comparison was used to determine their importance. This method allows for a systematic assessment of the importance of each objective by comparing each objective with others within the given area. Based on the results of the pairwise comparisons, the objectives are prioritized and given weights that correspond to their importance to the domain. This weighting is visualised by graphical slices surrounding the icon of each key area. The cut-outs illustrate the relative importance of each objective, but also help document users quickly understand the key priorities of each area. This approach facilitates the next steps in implementing the measures.

Novice drivers between the ages of 18 and 24 have a higher risk of accidents, which results from long-term published statistical data. The goal of training at driving schools should be the comprehensive preparation of future drivers for all traffic situations under various weather conditions. Using vehicle simulators allows this practice and training of future drivers, which can be fulfilled and practiced in all weather conditions. Moreover, the vehicle simulator practice can be subsequently (machine) evaluated. Based on the analysis of such driving, complex erudition and readiness of the future driver behavior in real road traffic can be achieved. This article discusses the capabilities of simulator software that can be applied to the education and training of future drivers. The article aims to present possibilities of evaluation software and related practical use in driver education in driving schools. At the end of the article, the expected benefits in the design of the evaluation software for the vehicle simulator are discussed, emphasizing road safety in the education of future drivers.

The world is gradually moving towards green solutions in all industries. This is the case in the automotive industry as well and it is logical that vehicle simulators must follow this trend and functionally approach the increasingly widespread battery electric vehicles (BEVs). The differences in the parameters of vehicle simulators with alternative powertrains have already been covered. This paper deals with the modification of both the simulator hardware and software to improve the behavior of the physical vehicle model, representing all functions through a programmable human machine interface (HMI) and providing an approximation of the driving experience of a real vehicle. The topic of this paper first describes the functional scheme and physical model of the simulator adapted for HMI simulations of BEVs and hybrid electric vehicles (HEVs). A prototype design of the virtual cockpit is also described. Then, the design of the experiment is explained to validate the displayed and recorded values through a qualitative study by pilot testing on a vehicle simulator. A discussion of the measured results is concluded.

The present paper focuses on vehicle simulator fidelity, particularly the effect of motion cues intensity on driver performance. The 6-DOF motion platform was used in the experiment; however, we mainly focused on one characteristic of driving behavior. The braking performance of 24 participants in a car simulator was recorded and analyzed. The experiment scenario was composed of acceleration to 120 km/h followed by smooth deceleration to a stop line with prior warning signs at distances of 240, 160, and 80 m to the finish line. To assess the effect of the motion cues, each driver performed the run three times with different motion platform settings-no motion, moderate motion, and maximal possible response and range. The results from the driving simulator were compared with data acquired in an equivalent driving scenario performed in real conditions on a polygon track and taken as reference data. The driving simulator and real car accelerations were recorded using the Xsens MTi-G sensor. The outcomes confirmed the hypothesis that driving with a higher level of motion cues in the driving simulator brought more natural braking behavior of the experimental drivers, better correlated with the real car driving test data, although exceptions were found.

Traffic engineers have long sought to understand what encourages drivers to drive fast and to design road infrastructure to induce drivers to behave in a desired way. But what leads drivers to select a particular speed while driving is principally a psychological question. This paper aims to expand the understanding of the factors affecting driving speed in built-up areas of towns and municipalities. We analysed nearly 700,000 vehicles-driving on roads of regional and supra-regional significance near the Bohemian Switzerland National Park-in 20 surveys at 17 locations. A broad set of infrastructure attributes was defined and measured at each site. The collected data were analysed using statistical methods to draw general conclusions about driver behaviour that can be used to improve traffic engineering. Several of the presumed attributes were confirmed to influence driver speed choice, and several new factors were discovered and proposed for implementation in traffic engineering and mathematical modelling tools.

The paper deals with the possibilities of implementing dynamic tariff regulation of on-street parking spaces in the capital city of Prague. Achieving optimal results is conditioned by the implementation of advanced technologies, but at the same time the dynamic tariff regulation must follow the applicable legislation and, above all, be accepted by drivers. For this reason, the paper briefly discusses the technical and legislative possibilities of implementation, and most attention is paid to the conducted survey of user needs. The survey investigates the impact of parking prices on drivers' motivation to park their vehicle in the area.

Driving simulators are increasingly being incorporated by driving schools into a training process for a variety of vehicles. The motion platform is a major component integrated into simulators to enhance the sense of presence and fidelity of the driving simulator. However, less effort has been devoted to assessing the motion cues feedback on trainee performance in simulators. To address this gap, we thoroughly study the impact of motion cues on braking at a target point as an elementary behavior that reflects the overall driver's performance. In this paper, we use an eye-tracking device to evaluate driver behavior in addition to evaluating data from a driving simulator and considering participants' feedback. Furthermore, we compare the effect of different motion levels ("No motion", "Mild motion", and "Full motion") in two road scenarios: with and without the pre-braking warning signs with the speed feedback given by the speedometer. The results showed that a full level of motion cues had a positive effect on braking smoothness and gaze fixation on the track. In particular, the presence of full motion cues helped the participants to gradually decelerate from 5 to 0 ms(-1) in the last 240 m before the stop line in both scenarios, without and with warning signs, compared to the hardest braking from 25 to 0 ms(-1) produced under the no motion cues conditions. Moreover, the results showed that a combination of the mild motion conditions and warning signs led to an underestimation of the actual speed and a greater fixation of the gaze on the speedometer. Questionnaire data revealed that 95% of the participants did not suffer from motion sickness symptoms, yet participants' preferences did not indicate that they were aware of the impact of simulator conditions on their driving behavior.

This article is about assessing whether eye-tracking technology is feasible as a tool for evaluating external HMI technology, which is a topic that will gain importance once autonomous vehicles become ubiquitous. For this end, research about external HMI concepts was done. Based on this research, two main set-ups of external HMI were identified. First consists of placing some form of signaling device (LED strips, light panels, etc.) on the front of the vehicle (upper part of the windshield or the grill). The second one is based on projecting the information on the road between vehicle and pedestrian. Experiment was carried out, simulating a pedestrian looking for external HMI clues whether to cross the street at unsignalized crosswalks. For the experiment, Tobii Pro Glasses II were used for detecting scene in front of the participant and their eye movement and fixation. The aim of the experiment was to ascertain whether the eye-tracker is usable in this kind of experiment, and if so, in what conditions. It was found out that for low traffic and certain weather conditions, eye-tracker can be used to distinguish a single vehicle from about 50 meters and finer elements can be distinguished from about 25 meters, which should be sufficient for external HMI evaluation.

The subject of the research paper „EYETRACKING TECHNOLOGY IN AUTOMOTIVE INDUSTRY“ is to implement eyetracking technology into development of new vehicles and decision making process. This objective technology tracks eye movement of a participant, detects where the subject is looking during an interval of an experiment, and thus offers wide range of applications. It can be used to detect distraction while driving on simulator under a certain workload or to record objective data during otherwise subjective costumer oriented clinic. In this topic, we evaluate areas of the vehicle which are the most interesting for customers and therefore, provide support and recommendations for new vehicle designs.

The simplest method of regulating on-street parking (in the cities) is a tariff regulation plan, changing the price of parking usually requires the least amount of money spent and is not contingent on the introduction of new technologies. Getting it right leads to a redistribution of demand and an important aspect is the relative price levels for off-street and on-street parking. The paper deals with the design of an algorithm for dynamic on-street parking control. It describes the process and results of a model implementation of the algorithm in a selected area. The proposed algorithm is intended primarily for cities or larger municipalities where parking regulation becomes a necessity and operates on the principle of real-time parking price adjustment. In conclusion, the possibilities of implementing the algorithm in real operation are evaluated and the possibility of further development and future research is outlined.

The article analyzes the accident rate and causes of road accidents. It has been found that in most cases traffic accidents occur due to drivers' fault. This is due to the low level of professional training and limited psychophysiological condition of the driver of the vehicle. The project of an interactive simulator is proposed. The analysis of existing designs of car simulators is carried out. The concept of a car simulator is substantiated based on the analysis. The use of the described driving simulator will allow identifying and weeding out potential traffic violators at the very stage of training.

This book summarizes the theory of quality assurance methods applied at the product development stage and stresses the necessity of interlinking such methods and performing them in an appropriate sequence, as well as the necessity taking a scientific approach to such methods, i.e., applying them in compliance with the DoE principles (Design of Experiments). A significant part of the book deals with the QFD method (Quality Function Deployment) that makes it possible to proceed from a verbal description of product requirements to a description of the product's technical parameters. Special attention is paid to the DFMAS / DFx method (Design for Manufacturing Assembly and Services) where one of the primary objectives is to minimize costs. Last but not least, the book also describes FMEA methods (Failure Mode and Effects Analysis) the cornerstone of which is designing a new process of method application, as independent of the human factor as possible, and implementing an expert system on the basis of such application with the possible application of artificial intelligence (AI). The book contains numerous examples from the automotive industry and describes actual hands-on experience of applying the said methods.

Engine or battery powered two-wheeled vehicles are an essential part of the transport system. Its users are however more vulnerable in comparison to personal vehicles. In general, compared to four-wheel vehicles, even a small percentage of accidents including motorcycles causes a significant share of all fatalities in the Czech Republic. Two-wheelers nowadays face the challenge of electric propulsion and wider user adoption. This fact emphasizes the need for rider behavior assessment. One of the ways of examining rider behavior in a safe and scientific environment is an interactive vehicle simulator. In order to develop a complex semi-active motorcycle simulator, a virtual model in Unity platform was created. The main purpose of this paper is to verify the longitudinal dynamics of the physical model for emerging the interactive simulator. To achieve this goal, crucial parameters of the model were set. For validation of the model, we defined several riding scenarios. Based on the data measured during a track test experiment in a real environment, further needed model parameters were indirectly defined. The results show that the output of the longitudinal dynamics model closely correlates with the real data gathered on the track.

Autonomous Traffic Management (ATM) systems empowered with Machine Learning (ML) technics are a promising solution for eliminating traffic light and decreasing traffic congestion in the future. However, few efforts have focused on integrating pedestrians in ATM, namely the static programming-based cooperative protocol called Autonomous Pedestrian Crossing (APC). In this paper, we model a Markov Decision Process (MDP) to enable a Deep Reinforcement Learning (DRL)-based version of APC protocol that is able to dynamically achieve the same objectives (i.e. decreasing traffic delay at the crossing area). Using concrete state space, action set and reward functions, our model forces the Autonomous Vehicle (AV) to "think"and behave according to APC architecture. Compared to the traditional programming APC system, our approach permits the AV to learn from its previous experiences in non-signalized crossing and optimize the distance and the velocity parameters accordingly.

The paper deals with the problem of a communication interface between autonomous vehicles (AV) and pedestrians. The introduced methodology for assessing new and existing e-HMI(external HMI) contributes to traffic safety in cities. The methodology is implemented in a pilot experiment with a scenario designed in virtual reality (VR). The simulated scene represents an urban zebra crossing with an approaching autonomous vehicle. The projection is implemented with the help of a head-up display – a headset with a built-in eye tracker. The suggested methodology analyses the pedestrian's decision making based on the visual cues – the signals displayed on the autonomous vehicle. Furthermore, the decision making is correlated to subjects’ eye behaviour, based on gaze-direction data. The method presented in this paper contributes to the safety of a vehicle-pedestrian communication of autonomous vehicles and is a part of a research that shall further contribute to the design and assessment of external communication interfaces of AV in general.

Nowadays we are facing the transition from human-driven vehicles to the higher levels of automated driving, where the driver's primary role does not have to be the driving as in its classical meaning. As the driving task would not be the primary, we can expect driver and all passengers to perform new activities while being in the vehicle. In this article we analyse results of four crash tests. One of them has a specific configuration, where the driver crash test dummy is set to the situation of the level four of the automated driving as if were carrying out some activity on the notebook. The research focuses moreover on free objects and the risks that they represent during the accident for passengers. The results of all four tests are mutually compared and discussed to get the idea how the unusual driver position including working activity could influence the impacts on human passengers. Other three configurations represent standard lateral crash test, frontal impact into the rigid barrier and the crash of the motorcycle. The results measured on the rider show extreme situation to which we can compare absolute values of drivers from the rest of analysed crash test. In the assessment we follow the parameters linked to the acting vehicles and of course parameters describing the impacts on drivers.

Urban comfort and safety go along with travel and traffic management for the cities. Facing automatization of transport brings necessity for the ITS solutions to provide efficient communication between vehicles, infrastructure and other traffic participants. Parking in the cities is a daily travel related task. Efficient automated parking solutions can contribute to individual time management as well as to reduction of traffic flow that is connected with parking spot search - especially in big cities. User acceptance of new technologies that arise with automated driving depends on their usability and interface. This paper presents a pilot demonstration of automated parking function with a mobile app interface. Observation of visual behavior (eye tracking) provide analyses of automated parking function and mobile app of modified electric prototype of e-vehicle "Skoda Rapid".

Aim of this article is to introduce and present advantages and possibilities of using simulation tools to calculate energy flows of tractive vehicle in all phases of its ride. The focus is on the braking phase, especially on the braking energy recuperation that offers the highest energy saving potential. Energetic simulation was carried out as a part of a current railway reconstruction study, which is a good example of possible energetic calculation use. Energetic calculation in the simulation are performed using so called "exact method" developed at the Faculty of Transportation. The advantage of the method is that it provides a high degree of accuracy. Due to the simulation calculation being performed in real-time, the user can enter the calculation even during the simulation. Crucial part of every simulation are quality input data, such as vehicle braking characteristic (including all working points below the envelope line together with the efficiency characteristics of the power train parts (engine, transmission, convertor and others)). Also, sufficiently precise (with a precision of 1 meter) railway track details (detailed geometrical and other information on the current and reconstructed railway track or on the railway track proposal. To present savings during the ride, the railway track section on the track Montreál-Sherbrooke was chosen. On this track, (especially electrification and partial reconstruction of the superstructure) is planned. Reconstruction level will be dependant on the local economical and social conditions. However, in the most optimistic case, total electrification of the track will be undertaken, or lower level of the reconstruction when the vehicles that have very similar characteristics. The railway track section is located between the cities of Montreál and Sherbrooke, that are 160 km apart. To compare the current, and possible future, state, comparison of energy consumption of the vehicle was conducted on the same track with the same geometrical characteristics. We can assume that the overall energy intensity of the ride on the newly reconstructed track (eg. with greater radius of the arches) will be lower than the overall energy intensity of the ride on the track before reconstruction. Current data on energetic consumption are not available, therefore they were obtained by simulation and verified by calculations and considered sufficiently accurate. Presumably, the input simulation parameters required for the simulation will not always be delivered in the sufficient quality or will be partly missing completely. In these cases they will be substituted by various algorithms, that can be machine-processed and that are part of the simulation calculations. One of the crucial algorithms is so called "moment efficiency". Its machine processing is not entirely developed and therefore, this simulation will be conducted witho

This article is about a study of the heart rate of drivers in a vehicle simulator and its changes when the drivers are confronted with critical and potentially collision situations. The drivers' heart rate was measured while driving in a car simulator. After traversing a certain section of the created simulation route, a critical situation occurred in the simulation, which forced the drivers to react quickly. The aim of this study was to determine the probability of a significant increase in heart rate of drivers after the confrontation with this critical situation and to deduce from this whether the measurement of heart rate in driving simulators can be used as an indicator of critical or stressful situations. The Wahoo Tickr X chest strap was selected to measure the heart rate of the drivers and 30 drivers of different sexes and ages were measured. A total of three minutes of heart rate recordings were evaluated per driver, two minutes before the start of the critical situation and one minute after the start of the critical situation. Three different methods were developed to identify a significant increase in heart rate after the start of the critical situation, and a comparison between the parameters of the section before the start of the critical situation and the section after the start of the critical situation was also performed. The first main result of this study is the probability of a significant increase in the heart rate of drivers in a vehicle simulator in critical situations. The second main result is a comparison of the extent to which this increase in heart rate is unique to the critical situation, i.e. whether similar or greater increases in heart rate occur even before the critical situation. The results of this study are generally applicable on any vehicle simulators including simulators developed for smart city vehicles.

Communication interfaces of autonomous vehicles have extended the human-machine interaction to the streets of the cities. This brings into picture the necessity of efficient infrastructures and cooperative systems and consideration of multiple human agents in the system. For efficiency of interface design process, there is a need of automated assessment tools to deliver part of testing through simulations, based on known parameters - physical, geographical and biological. Diversity of available external interfaces and absence of standardization in them give freedom for creative search of related technologies. This paper suggests a tool for assessment of various types of visual eHMI with the help of graphical method applied in a microsimulation model. The proposed method allows testing of different scenarios and adjustment of parameters for different vehicle design, interfaces and human behavior scenarios. The presented method is demonstrated on several types of visual interfaces. The paper provides introduction to the concept of vehicle external interfaces in the context of autonomous driving with relevant challenges of user communication described in related research. The methodology is then presented on a demonstration scenario with description of measured parameters that define efficiency of communication interface. The results show how placement of an interface affects its visibility to observer.

Electric powered motorbikes nowadays rapidly increase ratio across micro-mobility shared services. This trend is in addition supported with smart city development. The electric powered bikes bring specifics for the riders in sense of motorcycle control. Electric powertrain has different complex features that rider has to deal with and it is not primarily trained for. Current research typically copes with challenges such as route planning, travel range, daily recharging etc. Therefore, the research deals not only with external characteristics, but also with internal factors which can be affected by rider. This article aims to the specifics of riding the electric motorcycle compared to the conventional petrol powertrain. It is important to define crucial parameter trends to follow these specifics to increase safety of users and thus the traffic safety in the smart cities.

With increasing demands on green farming, the price of industrial fertilizers is also rising. For these reasons, the use of organic fertilizers is becoming more important, but due to the inhomogeneous nutrient content, it is not possible to apply them precisely. However, the development of modern sensors makes it possible to determine the nutrient content directly on the application tanker and thus to achieve the required nutrient application by changing the fertilizer dose.

The aim of the paper is to define the method to objectively evaluate rider behaviour for the future possibilities of modification assessments in the scope of Human Machine Interface. The advantage of the rider performance description is in the possibility of evaluation of applied measures in the rider-motorcycle system. In the paper there are presented techniques and methods of data collection with the focus on the parameters influenced by the rider. The rider and the motorcycle are the inseparable system. The inspiration in this field of study we can find in the motorsport application. The approach for the rider performance assessment is based on the experimental study performed on the race track. The obtained knowledge is applicable for the riding skills improvement as well as for the assessment of powered two wheelers users of micro-mobility smart cities platforms and, above all, for the safety increase.

Decrease of vigilance caused by sleep deprivation affects driving behaviour and results in delay in reaction and loss of vehicle control. This behaviour leads to increase of road accidents. The effect is typical at long commutes and monotonous roads with tedious landscape and is especially noticeable in so called vulnerable diver population groups, namely novice and senior drivers, shift and overtime workers. Prediction of such a behaviour shall contribute to vehicle safety systems through improvement of driver-car interface for prevention of sleepiness at wheel and decrease number of accidents caused this factor, where timely detection of a driver loss of vehicle control is crucial. Current study represents an experimental research on driving simulator with sleep deprived subjects from two age groups (senior, experienced drivers and young, novice drivers) and compares the vehicle control and lateral position ability based on analysis of vehicle lane position, deviation of speed, lane departure time and lane departure area in subject’s two state (fresh, rested state and induced sleep deprived state), while performing a car following task with speed-change cycles.

Variable applications of fertilizers have been applied for a long time and a number of works have been written about the requirements of applications. Nevertheless, technological advances bring new possibilities for applications accessing. An environmentally friendly approach, or legislative restrictions or requirements in addition to production and economic aspects are also being monitored today. The scale for decision-making is also reduced, leading to the need for more detailed monitoring. The need to search for deeper connections between factors also increases. All possibilities for application technology are significantly supported by sensor technology, GIS applications, data compatibility, telematics and GPS technology. The paper provides an overview of the application of modern technical elements or knowledge for the rational application of fertilizers.

The paper summarizes exhaust emissions measurements on two diesel-electric locomotives and one diesel-hydraulic railcar, each tested for several days during scheduled passenger service. While real driving emissions of buses decrease with fleet turnaround and have been assessed by many studies, there are virtually no realistic emissions data on diesel rail vehicles, many of which are decades old. The engines were fitted with low-power portable online monitoring instruments, including a portable Fourier Transform Infra Red (FTIR) spectrometer, online particle measurement, and in two cases with proportional particle sampling systems, all installed in engine compartments. Due to space constraints and overhead electric traction lines, exhaust flow was computed from engine operating data. Real-world operation was characterized by relatively fast power level transitions during accelerations and interleaved periods of high load and idle, and varied considerably among service type and routes. Spikes in PM emissions during accelerations and storage of PM in the exhaust were observed. Despite all engines approaching the end of their life, the emissions per passenger-km were very low compared to automobiles. Tests were done at very low costs with no disruption of the train service, yielded realistic data, and are also applicable to diesel-hydraulic units, which cannot be tested at standstill.

This document defines key terms and parameters applied in the analysis of driver visual behaviour focused on glance and glance-related measures. It provides guidelines and minimum requirements on equipment and procedures for analysing driver visual behaviour including assessment of TICS to: — plan evaluation trials; — specify (and install) data capture equipment; and — validate, analyse, interpret and report visual-behaviour metrics (standards of measurement). The parameters and definitions described below provide a common source of reference for driver visual behaviour data. It is applicable to on-road trials (e.g. field operational tests or naturalistic studies), and laboratory-based driving studies. The procedures described in this document can also apply to more general assessments of driver visual behaviour. Data collected and analysed according to this document will allow comparisons to be performed across different TICS applications and experimental scenarios.

There is no methodical approach suitable for definition of the periodical or non-periodical, stationary or nonstationary curves of brain signals with a help of amplitude, frequency, phase etc. values. It is difficult to determinate the wave shape, i.e. the problem is how to solve the respective pattern recognition. Therefore, we tried to propose a simple method for praxis by help of measurement two main wave time components, interpreting a sinusoidal alpha wave as a triangle, where there is an anterior and a posterior part of wave ascending and descending abscissas in a hope that the sufficient measure are presented by the "legs" only or distances between upper and bottom peak of the wave. All the values of total ascendants are divided by all values of total descendants. For the method validity estimation it was made for this computation separately in two different psychical states - the relaxation and the calculation activity, both with eyes closed. Results are presented as quotient (quotus alpha) which means alpha waves symmetry. If the quotient is equal to 1, or is near to 1, is the alpha wave full or almost symmetrical. When the quotient is lower than 1 the ascendant is shorter than descendent, then alpha wave is asymmetric and has inclination to the left side. In contrary if the quotient is higher than 1 the ascendant is longer than descendent, alpha wave is again asymmetrical, but inclination is oriented to the right side. During mentation is usually quotient lower one and the ascendant is still more lover, alpha waves are sheer, the inclination to the left is more expressive.

Artificial systems play an extremely important role in human life. Each day, almost all people on the Earth have to interact with various complex systems, which are of a very different nature and target application. These all system structures and their whole sets can be of various degrees of complexity and can be discriminated into many categories. These three can be considered as their main kinds: • artificial systems, • living systems, • natural systems. All of them could have very various behaviours but some aspects – as well as their theoretical backgrounds – are universal. Artificial systems are those created by the human, so mostly by human will and decisions.

One of the major ways to achieve reduced energy usage in transportation and associated financial benefits is to reuse the energy obtained when a vehicle is braked by an electric motor. Such recovery of energy is called recuperation and is only possible in the case of driving the vehicles with an electric propulsion. The most effective and most frequent method to gain energy this way nowadays is its recuperation in form of electric energy with the help of electro-motors. In our country, the extension of electric motors in operation is only in railway transport, which this article will be devoted to.

The aim of this work is to present Real-Time Driver Advisory System (RTDAS) for improving energy economy of Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV). System relies on a road map data provided in accordance with the second version of Advance Driver Assistant Systems Interface Specification (ADASIS v2) Protocol. Road map data is then transformed into Electronic Horizon (EH). The Electronic Horizon provides a preview of the road characteristics ahead of the vehicle, which is used for development of a predictive energy economy algorithms. The system is focused on static characteristics of the road ahead such as road slope, curvature, superelevation, speed limits and the traffic signs. Based on this data and vehicle parameters, the system is using algorithms to define if and when to send a message to the driver to release the gas pedal and to achieve higher energy economy, comfort and safety of driving. The releasing of gas pedal triggers an algorithm to adjust the speed using controlled regenerative braking without using mechanical brakes that leads to optimization of vehicle kinetic energy recuperation.

During experiments on vehicle simulators a large amount of data is stored. On these data, it is possible to trace some similarities in the behavior of drivers in certain areas or when performing the same task. We can assume that if the driver performs a certain type of experiment, his behavior exhibits certain traits. These elements of common behavior can be used to create virtual track for experiments. Which elements and how they can be used is described in this article. The algorithm for automatic creation of virtual track based on type of experiment is provided. It will help us to define the purpose of measurement and the track could be generated automatically

One of the modern methods of testing new systems and interfaces in vehicles is testing in a vehicle simulator. Providing quality models of virtual scenes is one of tasks for driver-car interaction interface simulation. Nowadays, there exist many programs for creating 3D models of road infrastructures, but most of these programs are very expensive or canÂtt export models for the following use. Therefore, a plug-in has been developed at the Faculty of Transportation Sciences in Prague. It can generate road infrastructure by Czech standard for designing roads (CSN 73 6101). The uniqueness of this plug-in is that it is the first tool for generating road infrastructure in NURBS representation. This type of representation brings more exact models and allows to optimize transfer for creating quality models for vehicle simulators. The scenes created by this plug-in were tested on vehicle simulators. The results have shown that with newly created scenes drivers had a much better feeling in comparison to previous scenes.

The article considers a possible improvement of road vehicle safety by using eCall – a system which initiates an emergency call in case of traffic accident. A possible way of better description of a frontal impact accident of a vehicle is examined and enriched by the information from the onboard e-call unit. In this article, we analyze results of frontal crash tests with different types of barriers and overlapping area and look for the correlation between the individual vehicle and collision parameters in order to provide a better description of the severity of the accident by the eCall system. The relation among the selected parameters is described using the correlation analysis.

By means of a development of an e-bike sharing system the Electromobility Project wants to provide an alternative way of comfortable transportation for students and staff of the CTU, primarily to commute between different campuses. The research for this project contains at least three different fields of study, namely electric vehicle and docking station development, intelligent transport systems and management and economics of transportation and telecommunication. After briefly stating general requirements for the sharing system, this paper focuses on the development of the electric bicycle. First an ideal bike design is defined. Then necessary motor power and battery capacity are calculated by estimating characteristics of cycling in Prague. A prototype was developed by converting a normal bicycle to an electric bicycle. Being equipped with devices for e-bike monitoring, controlling and data recording for a post trip analysis, this prototype is also intended to have an educational value for future students in the project. Results consist of an electrical bicycle configuration that matches the requirements and a sketch of an ideal e-bike for this project.

A specialized simulation system, which allows a detailed examination of individual cases specified by the parameters of the track used vehicles and transport technological conditions, satisfies the requirements set. Specific cases should be examined variable enabling the optimal solutions selection. The mentioned simulation system represents the core of an energy simulatortrainer, which is being developed at the Laboratory of transport energy in Institute K616 at the Faculty of Transportation Sciences. Sub-themes of the development are subjects of doctoral and other study projects (see below references to some publications devoted to this topic). A concept of the energy simulator is based on a newly conceived computational algorithms based on special input data sets that characterize traction and energetic characteristics of driving vehicles. This is necessary in order to achieve the highest possible accuracy of the calculations, which is a necessary assumption for variant solutions. The concept of energy simulator-trainer allows the study of rail and road vehicles with electric propulsion system and also of vehicles with combustion engines. A significant feature of the concept is the possibility of a functional connection to the vehicle's educational trainer developed also at the Faculty of Transportation sciences.

The model car transport system is a laboratory intended for a practical development in the area of the motor traffic. It is also an important education tool for students’ hands-on training, enabling students to test the results of their own studies. The main part of the model car transportation network is a model in a ratio 1:87 (HO), based on component units of FALLER Car system, e.g. cars, traffic lights, carriage way, parking spaces, stop sections, branch-off junctions, sensors and control sections. The model enables to simulate real traffic situations. It includes a motor traffic in a city, in a small village, on a carriageway between a city and a village including a railway crossing. The traffic infrastructure includes different kinds of intersections, such as T-junctions, a classic four-way crossroad and four-way traffic circle, with and without traffic lights control. Another important part of the model is a segment of a highway which includes an elevated crossing with highway approaches and exits.

This article focuses on the application of the Quality Function Deployment (QFD) method and shows how we can use this method in the automotive industry. The cockpit of the modern car is still developing and changing according to technical progress and customers’ requirements. The QFD method enables the setting of the customers’ requirements and then puts them into technical expression. The matrix of QFD sets those technical expressions that are the most important properties customers expect. These chosen properties can be tested during the technical development. The testing of new HMI concepts goes through a driving simulator and can suggest which one is suitable for being used in a real car.

In this article, we propose a software solution to study HMI of electric and hybrid electric vehicles in vehicle simulators. We will start from the description of a development process of a physical model for HEV simulation in IGNITE software and equation based language Modelica. A short introduction to the language, its possibilities, and explanation, why it is more suitable for the development of such models (vehicle powertrain), are presented in the first part of the article. A fusion mechanism of physical engine with the model by means of FMU (Functional Mock-up Interface) [3] is also described in this part The second part is dedicated to the description of the model constructed in third party software IGNITE. This model has a detailed calculation of energy consumption and energy flow based on the selected control strategy. The last part of the article describes a possible experiment methodology.

The paper deals with the issue of fatigue and sleepiness behind the wheel, which for a long time has been of vital importance for the research in the area of driver-car interaction safety. Numerous experiments on car simulators with diverse measurements to observe human behavior have been performed at the laboratories of the faculty of the authors. The paper provides analysis and an overview and assessment of the subjective (self-rating and observer rating) methods for observation of driver behavior and the detection of critical behavior in sleep deprived drivers using the developed subjective rating scales.

Energy costs impact directly or indirectly economic balance of urban transport. There are not only economical influences, but also other - amount of energy consumption affects the world from energetic or ecological side. It is around 30 percents in economical sheet of urban transport companies. Due to this fact it is very important to look for possibilities of savings. Nowadays there is a strong social demand for sustainable transportation; development and producing of system and subsystems of (mainly rail transportation as backbone) transportation and to become a pillar of sustainable multimodal mobility as a carrier. Actually, current trends are mainly the following: decarbonisation of mobility (to relieve the transport of fossil fuel dependence), mobility without emissions (to eliminate such type of transports which have unfavorable influence on life environment), less hard work transport (replacement of routine human labor by machines) and other trends not directly related with the issues this article focuses on. The energy resources exhaustibility as well as the increased ecological load that is inseparably connected with energy consumption represents a very important social issue. A solution of the environmental load problem is acute particularly in densely populated urban areas. It is therefore advisable to pay an attention to the energy consumption issue and its rationalization. The means of this rationalization effort are the knowledge of all relevant decisive factors specific to the transport system, respectively for its organic part and for its particular transport technological conditions. A simulation of the specific operations and technical and technological situations represents a tool for the detection of relevant connections and their quantification. A method of investigation of alternative cases is appropriate for purposes of an analysis and subsequent rationalization of decision-making processes.

This document describes the evaluation of the platform for studying problems associated with HMI for vehicles with alternative propulsion developed as a part of the grand Advanced assisting systems and their UI for future EV and HEV. This evaluation is based on design and analysis of two experiments on interactive vehicle simulator. First experiment deals with the evaluation of user acceptance of the HMI for EV based on the VW eGolf concept, including regenerative braking and second experiment evaluates user acceptance and practical benefit of the Driver Advisory System which aim is to increase EV range by advising driver when to release an acceleration pedal to reduce the speed before next limitation, with heavy usage of regenerative braking. Both subjective and objective data were used to evaluate not only particular experiments but also the platform as a whole.
