The paper provides an overview on mobility challenges in the tunnel environment, it summarizes requirements on safety and emergency response that are negatively affected by limited availability or even lack of Global Navigation Satellite Systems in tunnels. The paper provides an alternative way on how to enable positioning in tunnels by using additional Bluetooth Low Energy (BLE) infrastructure with a focus on emergency response. The BLE infrastructure supports advanced systems such as Cooperative-Intelligent Transport Systems (C-ITS), and therefore it is possible to disseminate locally relevant information among the cars and to the tunnel operators. The paper considers various scenarios and provides use case definition supported by testing of C-ITS and functional validation from the Blanka tunnel in Prague. The proposed solution improves usage applications that require accurate positioning data to ensure proper functions, and therefore enables use of navigation in the tunnel environment. These could help to general use for wide range of drivers, however, the main goal is to efficiently assist during the rescue and recovery, or even smooth pass of emergency vehicle. The presented outcomes support preparation of strategic documents for Czech legislation and standards for the gradual installation of technologies in the tunnel, leading to better dissemination about emergency and other unexpected events to improve driver awareness through vehicular communication and reliable navigation.

The aim of this paper is to present the possibility of applying the preference of electric vehicles at light-controlled intersections in terms of positive and negative aspects. To increase the usage of electric cars in cities, various supportive efforts are arising. The authors aimed to answer the question when and under what conditions it is worthwhile to install the preference of electric vehicles at light-controlled intersections. The proposal was tested on a case study of a real intersection through microsimulation. The results confirm the positive effect of electric vehicle preference, especially in terms of reducing the relative delay of preferred vehicles compared to the delay of all vehicles on the network. With increasing penetration of electric vehicles, the results also show a slight increase in the overall delay of all vehicles. However, the negative effect of increasing penetration is significantly lower than the effect of increasing overall vehicle flow.

The main objective of this article is to provide an evaluation of appropriate technologies for positioning in road tunnels. In tunnels, there are even more strict requirements for operation and safety compared to regular road infrastructure. The operation, traffic efficiency, and safety could be increased by using technological equipment, intelligent transport systems, smart traffic solutions, navigations, etc. However, these require location information to run smoothly with their proper functionality. Positioning is based mainly on the Global Navigation Satellite System (GNSS) approach and is very common because of its availability. However, in tunnels, the GNSS signals are shielded by the tunnel structure, and thus the GNSS approach is inappropriate. The article points out that the alternative way of localization could have a profound impact and could be considered by policy makers, tunnel infrastructure directors, safety regulators, etc. In the article, the evaluation of alternative positioning approaches in the GNSS denied environment is presented. The evaluation was carried out using a comprehensive analysis with multi-criterial decisions based on the combination of the Saaty and Metfessel methods. According to the stated criteria, the Bluetooth Low Energy (BLE) based approach received the best overall evaluation score, and is 1.62 times more appropriate compared to other on average. The selection of BLE is caused mainly by its relatively low investment and operational costs, together with low requirements on its applicability in tunnels without any intervention or modification of existing or already deployed systems. The BLE based positioning is also available for a wide range of users. Therefore, the BLE based solution is proposed and presented by practical examples of experimental measurements in the Blanka tunnel.

This paper provides an overview of the current challenges that occur within the design of the urban mobility concept and urban development concept. These challenges are discussed in view of the unique ELABORATOR project, which brings together different approaches and measures in a total of 12 European cities to improve micro mobility and sustainability and prove a concept toward climate-neutral cities. The main goal of the paper is to clearly describe the current state of mobility in the city of Liberec in the Rochlice housing estate area with the main objective focused on parking availability and identification of undesirable phenomena (incorrect parking, exhausted parking capacity, difficult passage for rescue services etc.). Therefore,the definition of ongoing problems is described from default to design and propose strategic interventions towards efficient parking supporting local mobility needs. Parallelly, the evaluation methodology is defined according to the requirements of strategically defined goals in sustainable urban mobility plans and the goals of the project. The proposed methodology reflects in situ measurement, identification of large-scale impacts based on quantitative analysis, and qualitative feedback collection from public events and applied interviews with city residents, and last but not least, the use of shared experiences of cities within the ELABORATOR project. This complex solution is defined to improve parking availability and to measure the real impact of proposed interventions on traffic on dedicated housing estates.

An integral part of modern cities within Smart City concepts is the development and related innovations in traffic control systems. New proposals need to be carried out in accordance with the applicable legislation and at the same time on a sufficient data base. This paper reflects the first conclusions of the research project SENDER, the aim of which is to develop, using deep learning methods, such a system that will warn drivers of impending danger in front of selected traffic intersections based on recognized data in the image from installed cameras. The paper mainly describes the process of selecting traffic situations in the area of intersections, which it is appropriate to warn the driver about. As part of the research, a state-of-the-art analysis was first carried out, which summarizes knowledge from current traffic control systems and the possibility of identifying collision situations, then the expert team defined collision situations that may occur in the node, including accompanying prioritization. On the basis of this identification, a specific intersection in the city of Brno was selected, which was fitted with cameras, and a test was conducted to determine whether the defined collision situations at the intersection actually occur. For the purposes of the developed system, this results in the specification of preferred collision situations, and these will then be simulated in variants with minor changes in the input parameters, in order to create a large enough database for learning the neural network.

Navigation services and other traffic applications are nowadays widespread, and their use is very common. These applications have an impact on traffic flow, driver awareness, and driver safety; however, a determination of the actual position of the end device is required. Most of such applications use Global Navigation Satellite Systems (GNSS), which cover a significant part of the transport infrastructure. However, in a GNSS-denied environment, these commonly used methods are either unavailable or significantly limited.For example, in road tunnels, signals are blocked by the tunnel structure itself. Nevertheless, tunnels are part of critical infrastructure and, in addition, have higher requirements to ensure safety compared to other transport routes. This article proposes an alternative method to determine position using data from additional Bluetooth Low Energy infrastructure. Furthermore, the localization approaches are presented together with the evaluation and its accuracy and stability assessment. The localization infrastructure was tested at various speeds during tunnel closure and during the real traffic scenario. The median positioning error ranges between 15-20m and decreases with distance, providing a stable, reliable, and cost-effective solution, particularly suited for long tunnels with varying curvatures. Therefore, it offers a practical use with significant impact on traffic safety and efficiency.

This article addresses the challenges operators face in decision-making during the operational management of tunnels and other transport systems. Operators of complex systems must process vast amounts of information and suggestions from various devices, subsystems, and both internal and external sources. In addition, they receive requests from multiple entities. This overwhelming influx of data and demands places significant pressure on operators to evaluate and respond swiftly and accurately, which is often crucial to ensuring smooth operation of the entire transport system. To assist operators in making better decisions, new approaches are being introduced, such as expert systems and artificial intelligence.

This article focuses on the use of predictive diagnostics and maintenance of technological equipment and systems in tunnels. Based on data analysis and new conditions for equipping urban and highway tunnels with new ITS technology such as C-ITS, there are new methods of vehicle detection and deployment, and operation of already existing systems (ventilation, fire alarms, traffic signs, control systems), a range of requirements increase together with specifications for maintenance and tunnel inspections. Predictive diagnostics is required to ensure the reliability of data and information of the equipment and particularly systems implemented in the tunnels. The goal is to operate an effective and reliable maintenance with targeted service interventions. The maintenance requires a well-defined documentation which is being prepared and applied in a BIM approach and overall digitization that significantly helps with orientation in the tunnel and its technological systems. There are descriptive technical documents that pointedly specify proper equipment functions as well as detection of reliability and life cycle prediction based on the actual states of equipment. Using SCADA in the tunnel control system allows simulations of system behavior, including fault detection and alarms. The article analysis various inputs, data acquisition, combination of parameters, and information, furthermore a methodical approach for supplementary predictive maintenance of road tunnel technologies on highways or cities roads. The analysis of an essential contribution to the maintenance and refinement of the equipment life cycle will be presented on an example, including the prediction of future states. The article includes examples of potential failures that are being solved during the operation with an impact on the entire predictive maintenance system. For data transfer, its redistribution, including information from systems, the provision of information about the state of the device, and the calculation of the subsequent life cycle, it will represent the basis for new approaches ensuring secured data transfer, i.e., the application of cyber security and other new approaches, where the continuity and application of new trends will be indicated.

A number of Czech and European cities are dealing with growing volumes of traffic and the increasing degree of motorization. One of the important issues that cities must address in the future is sustainable urban mobility. There are many approaches to solving sustainable mobility, they can be measures of a construction, technological or organizational type. Based on current European and Czech trends, this paper summarizes research into the possibilities of applying new approaches to solving urban mobility with a focus on the use of intelligent transport systems, including C-ITS. On the basis of the research, quite specific possibilities of applying these approaches are proposed for the real identified problems of selected Czech cities, which in their localities are currently solving the problems of transit transport, electromobility, parking, the application of new trends in vehicle detection, the use of public transport and its preference. The goal of the paper is always to show the possibilities of applying new ITS technologies for sustainable mobility, depending on the safety and flow of traffic. Another trend in cities is autonomous mobility, where the use of C-ITS can be a suitable prerequisite for the application of autonomous systems. Last but not least, it is necessary to address the issue of cyber security and the continuity of other subsystems in the framework of design, implementation and evaluation in transport management and information. The issue of the paper is solved within the framework of research projects SGS22/079/OHK2/1T/16 and TAČR CK01000163, CK03000179, CK04000027, CK04000082, FW03010458

The article summarizes the results of an EEG validation study following the proposal of a methodology for identification and monitoring of air traffic controllers’ fatigue level based on layered-voice analysis (LVA) described in the initial study (Kouba et al., 2020). 10 licensed air traffic controllers from APP Prague participated in the experiment that enabled the comparison of the state of vigilance during certain parts of the shifts rostering cycle. Methods for subjective assessment (Karolinska Sleepiness Scale) of fatigue were used as well as objective methods (Psychomotor Vigilance Task, Oddball Task and EEG power spectra analysis) to compare with the outputs of voice analysis. Our results indicate that the method of voice analysis reacts to changes in a person's mental state. Based on the results of current study, voice parameters marked as Stress and/or Energy levels seem to be the most suitable candidates for fatigue detection as shown by comparative statistics and correlations. The change in these parameters best reflected changes observed in EEG power in different band both during the cognitive testing and during the simulation exercise. According to our research voice analysis is able to identify differences in wakefulness and fatigue, as its results correlate with changes in brain activity. As our experiment likely induced not only fatigue but also changes in other mental states such as perceived stress which could have been reflected in the changes of other voice parameters, this could be the focus of the following studies.

The operation and maintenance of each technological system are essential parts of the life cycle. This article describes the result of the analysis of diagnostic data from tunnel equipment and its use. The analysis was carried out with the main objective of finding relations that could be further applied as a specific approach for the diagnostic procedure and possibly for future predictive maintenance of tunnel equipment. The article summarises the research of the project focused on the suitability of diagnostic data for potential use of predictive data-driven maintenance of technological parts in road tunnels. Data records were captured in the technological and tunnel control systems deployed in the Czech tunnels. The relations between warning and failure notifications were analysed together with the selected physical conditions of tunnel equipment during the operation by using measurements of technical parameters such as undervoltage, temperature, etc. Additionally, the impact of these parameters was monitored and evaluated according to the life cycle of the equipment. This resulted in a sequence analysis of states and events detected on particular equipment. In the article, the relations between measured technical parameters and failures are presented, together with the solution proposal that could be applied for failure prediction and enhancements of road tunnels operation and its technological systems by applying predictive maintenance of tunnel equipment. The presented outputs show that the cause of VMS failures can be the reaching of a critical device temperature or undervoltage, that are measurable, detectable even before the failure itself, which can be potentially predicted in this way.

As part of the development of new technologies and approaches, there are innovative solutions for intermodal transport, especially at the interface between road and rail. Among the basic trends in the development of the transport system, with a focus mainly on progressive areas that complement each other and are also newly developing, such as the requirement to obtain data and information for information modelling. Information modelling can obtain data using various methods that are presented in the article, where in particular the HD mapping method seems to be a very progressive approach, as well as obtaining data from technologies and smart approaches using connectivity using optical cables, IoT or the future 5G network with cyber security. The mapping of objects using 3D, the use of BIM (building information modeling) in design for the precise description of a given object or device for the subsequent provision of a complex cycle of a given system, is also an essential input for information modelling. The article concentrates in a comprehensive manner on the development of the transport system with a focus on the road and railway interface from the point of view of providing data and information for the design, implementation, and subsequent maintenance. An important aspect of the transport system is its user, the passenger, who uses and provides data and is offered for multimodal and intermodal transport, especially the application of the so-called Mobility Hub with the prospective provision of autonomous mobility, which in the future can be an important connecting element in multimodal and intermodal transport at regional or city level.

Smart cities and smart mobility necessitate the development of newly adapted approaches and applications that ensure data connection among their particular parts; thus, the complex systems of smart technologies can be applied. Especially in the field of transport, mobility, and smart solutions, many of these applications require precise localization. Global navigation satellite system (GNSS) localization is used mainly because of its availability, reliability, and sufficient precision. However, there are also blind spots in smart cities where the GNSS is not available, e.g., in tunnels. This article presents an approach to fixing the issue of localization in road tunnels based on telecommunications with Bluetooth low energy (BLE) based infrastructure equipment. This approach enables us to ensure sufficient data resources for localization, and thus, smart applications can also be applied in the tunnels. At the same time, this approach also allows the fulfillment of individual needs according to the specifications of each tunnel or smart application. The outputs from testing and measurements are presented and discussed.

The article presents two significant localities in Prague, Czech Republic, where new complex approaches of urban and transport engineering in public space will be applied. The paper will present important urban planning measures and specific proposals for the solution and incorporation of transport into public spaces, which will lead to the calming of the automotive transport and also its fluidity will be maintained. Furthermore the requirement for public transport, bicycle transport and above all to necessary pedestrian relations will be reflected. Integral part of the basic preparation is the economic and transport-engineering analysis, which generally fits into urban planning in given localities. Results of these analyses would be projected to prepared plans and actual projects from praxis. The text of the article would be focused mainly on the localities in the phase of project studies in Prague, specifically in Vyton and Hlavka bridge. The Vyton area is a busy set of intersections and tram transport and adjoining public transport stops, as well as important transfer and pedestrian connections. The reconstruction of the railway bridge is being prepared in this territory and the construction of new railway station with transfer relation to tram transport and ferry is also related to it. There should be also a pedestrian zone, which will contribute to the urban character of the area and safer connections for pedestrian destinations and transfer relations. Within the project, it was necessary to address not only all the present means of transport – automotive, trams, railway, bicycle, ferry and pedestrian movement, but also static transport that has an impact on the character of the district. The second locality, which was dealt with from the economic and transportation point of view was northern forecourt of Hlavka bridge, which is significant traffic intersection. At the same moment, there is an important public transport hub with transfer relation between underground line C and the trams. Apart from the maintaining the transport function of this node, the challenge of the urban approach is to deal with pedestrian connections and bicycle transport in two height levels, which means elevation in very cramped conditions. In the future there should be built a new building of Philharmonic, which will completely change the transport functioning of the area. These new heavy relations would be essential to resolve with the complex point on view and with wider impacts to the closest surrounding of local roads, but even to the through road of the city from north to south and contrariwise according to the traffic requirements. The goal and focus of this article is to present issue of two significant localities from several points of view – from economic to transport-engineering and urban applications within public space, which has fundamental impact on the

Cooperative Intelligent Transportation Systems (C-ITS) aim to increase safety, optimise traffic flow, reduce traffic congestion, improve economic efficiency of transportation, and operate the telematic systems implemented in the infrastructure. The main goal is to increase the awareness of road users. These aforementioned indicators are crucial not only on conventional transport infrastructure but especially in tunnels, which require even stricter criteria and requirements for traffic safety and especially response to unexpected emergency situations (accident, traffic jam, fire, movement of people, etc.). The article focusses on the application of C-ITS in urban and highway tunnels, which could significantly contribute to the ease of orientation and guidance of road users, the elimination of unsafe drivers' behaviour, fluidity of traffic, and integrity of the control system in relation to vehicles and other technological systems that are widely used in tunnels. However, a major limitation in tunnels, and especially in complex urban tunnels with junctions, is the absence of a GNSS signal, which is the common source of positional data for a significant part of traffic applications for drivers. This makes tunnels a blind spot in the transport infrastructure, although the use of C-ITS in tunnels would be justified and would make even more sense than on other transport routes such as common highways. However, C-ITS itself can also be used for positioning through communication between the infrastructure and equipped vehicles. This article reports on the possibilities of using C-ITS communication for automatic positioning and thus making C-ITS applications operational in tunnels, which can provide new use cases that meet the specific needs and requirements of tunnel structures. Some data are important for the tunnel control system and the determination of even potential faults and the link to the service and maintenance, where equipment fault behaviour may occur, tracking of maintenance vehicles and the transmission of information through the tunnel control system, and many other data and information that can lead to a reduction in the economic intensity of the operation and maintenance of the tunnel, the reduction of damage caused by traffic excesses, as well as the increase of traffic flow and its efficient use. This paper will focus on specific C-ITS solutions applicable in practice in road tunnels, including safe and secure data transmission

This article presents the use of the combination of the object detection method and feature detector in an infrared video on traffic infrastructure and in tunnels. The theme of the paper is the validation of vehicle detection and its classification using infrared video streams. In addition, the article focuses on the use of a feature detector and object detection to distinguish between vehicles with electric and combustion motors. The method suggests the use of a low-resolution thermal camera as an inexpensive extension of installed thermal camera technologies. The developed system has been verified for the applicability of vehicle detection and classification using object detection methods and their application in transport infrastructure and tunnels. It also presents a method for distinguishing propulsion units into electric and internal combustion; both systems’ conclusions are then statistically verified. The application of the system is evident in regional traffic management systems, including safety applications for traffic control in tunnels. Categorizing vehicles provides valuable information for higher levels of traffic management, toll systems, and municipal database systems, as well as for a preventive system for estimating vehicle conditions and their potential of fire in tunnels

With the development of intelligent transport systems in cities, the efficient use of big data is becoming increasingly important. The aim of this paper is to focus on specific sources of Big Data and specific outputs that can be obtained from these data in the conditions of the Czech Republic and then use these to propose recommendations for traffic solutions in a specific traffic area in Prague using the Pelc-Tyrolka area as a case study. In the research part, good examples of practice in the use of Big Data for transport solutions in the area abroad are found. These are then confronted with the real situation within Prague. In the methodology part, the procedure for effective processing and evaluation of different data sources (detector data, FCD data, data from information systems) is defined. Based on this procedure, data from the Pelc-Tyrolka area was evaluated to assess two specific traffic solutions in the area, and based on the results, recommendations were then proposed for future solutions in the area. Finally, the conclusions from the case study are generalized for the future use of Big Data in transport in the conditions of the Czech Republic.

Článek popisuje možnosti využití revitalizace průmyslových areálů pro bydlení. Tyto záměry se postupně více rozšiřují tak, jak jsou rušeny některé průmyslové brownfieldy zejména v centru města, jež vznikla transformací různých průmyslových odvětví v 90. letech minulého století. V centru měst se tak vytváří nedostatečně využívaná plocha, která je zanedbaná, často může být kontaminovaná. Nejsou to jen průmyslové areály, ale například i vojenské nebo zemědělské usedlosti. Cílem je na těchto revitalizovaných plochách vytvořit obytné centrum nebo obchodně-kulturní zázemí, popřípadě kombinaci komerčního, obchodního a kancelářského centra. V dané lokalitě definovaného území se pak prolíná nová výstavba s možností využití historických objektů s požadavky na kvalitní dopravní obslužnost a celkovou úprava veřejného prostoru s orientací na aktivní zázemí pro obyvatele se zelení.

Der Artikel beschreibt die Möglichkeiten, die Revitalisierung von Industriegebieten für den Wohnungsbau zu nutzen. Diese Pläne werden schrittweise erweitert, da einige Industriebrachen abgerissen werden, insbesondere im Stadtzentrum, das durch die Umwandlung verschiedener Industrien in den 1990er Jahren entstanden ist. Dadurch entsteht ein ungenutzter Bereich im Stadtzentrum, der vernachlässigt und oft kontaminiert werden kann. Dabei handelt es sich nicht nur um Industriestandorte, sondern beispielsweise auch um militärische oder landwirtschaftliche Anwesen. Ziel ist es, auf diesen revitalisierten Flächen ein Wohnzentrum oder ein Gewerbe- und Kulturzentrum oder eine Kombination aus Gewerbe-, Geschäfts- und Bürozentrum zu schaffen. In der gegebenen Lokalität des abgegrenzten Territoriums vermischt sich der Neubau mit der Möglichkeit der Nutzung historischer Gebäude mit Anforderungen an eine hochwertige Verkehrserbringung und der allgemeinen Umgestaltung des öffentlichen Raums mit der Ausrichtung auf einen aktiven Hintergrund für die Bewohner mit Grün. Der Artikel stellt zwei geeignete Beispiele aus der Praxis vor, die sich auf die Revitalisierung von Industriegebieten in der Gegend von Zličín und Pragovka konzentrieren, wo neue bauliche Ansätze, Änderungen des öffentlichen Raums, die Verkehrserreichbarkeit und die insgesamt angemessene Entwicklung der gegebenen Lokalität für das Leben angewendet werden .

The widely accepted body, The World Road Association (PIARC), has published research that up to 60% of future road tunnel operating costs can be saved by optimizing the tunnel design at an early stage of project implementation [1]. The paper shows the paradigm of recent years – more and more innovative technologies for tunnels do not necessarily mean that the functions for which tunnels are built are performed more efficiently. A road tunnel is a complex system created as a pragmatic alliance of several subsystems and many devices from different suppliers. Tunnel documentation usually has several hundred pages prepared by specialists in ventilation, lighting, safety, etc., and it is difficult for the investor or administrator to optimize the equipment without a detailed model of this complex system. There are two models for describing a complex system: a process model and a knowledge model. The paper shows that a more suitable model for describing a tunnel system is an ontology-based knowledge model and gives an example of such a model.

The review discusses the possibilities of different driving mechanisms and sensors of spherical robots, and a special kind of mobile robots is introduced and discussed. The sensors discussed can expand robots’ sensing capabilities which are typically very limited. Most spherical robots have holonomic characteristics and protect the inner environment using a shell. Today, there are a diversity of driving mechanisms. Therefore, this article provides a review of all of them and identifies their basic properties. Accordingly, many spherical robots have only inner sensors for moving, balancing, driving, etc. However, a few of them are also equipped with sensors that can measure environmental properties. Therefore, in this paper, we propose the possibility of using such sensors as cameras, LiDARs, thermocouples, and gas sensors, which can be used for special purposes underground, for example, in mines, underground tunnels, or road tunnels. After combining all components are combined, it is possible to design a special type of spherical robot designed for underground exploration, such as accidents in mines or road tunnels.

Největším rozvojem státu jsou města a navazující dopravní infrastruktura, a to zejména ve vyspělých částech světa, kde se klade důraz na zajištění veškerého komfortu v rámci veřejného prostoru. Nové trendy požadují digitalizaci, nové materiály, environmentální neutralitu, spolehlivé zajištění zdrojů vody, energie, plynu. Do těchto požadavků spadá i zajištění dostupné a zejména udržitelné dopravní obslužnosti (udržitelné mobility), zajištění komplexních služeb až po zajištění zaměstnanosti, sportovního a kulturního vyžití. Města se tím stávají mnohem složitější na organizaci, řízení a údržbu s větším přesahem do svého nejbližšího okolí, jež se dále stává rozsáhlejším s postupnými silnými vazbami na městské centrum a u velkých měst přechází do aglomerací města. Města se tím na jedné straně stávají závislá na technologiích, dopravní obslužnosti, energetických zdrojích a digitalizaci, a na druhé straně se významně posouvají do vlastní svébytné funkce a jsou základním motorem ekonomického bohatství, jež pomáhá k dalšímu růstu nejen vlastního města, ale i dané aglomerace, regionu a státu.

Featured Application This article provides a general overview of technological aspects and limitations of tunnels with respect to smart technologies such as C-ITS. Many smart city applications work with calculated position and time using the Global Navigation Satellite System (GNSS) signals for enhanced precision. However, there are many places where the availability of GNSS is limited, e.g., road tunnels, which are an essential part of transport infrastructure. Tunnels also require greater attention and greater importance of approaches to ensure the safety and security aspects of traffic. The safety, distribution of information, awareness, and smooth traffic can also be ensured by V2X applications, but the current position is also needed. An experimental analysis of data connection and communication availability was performed in the Blanka tunnel (Prague) and its surroundings. The main objective of the work was to find and clearly describe the tunnel blind spots, with an emphasis on communication between cars and potentially between cars and infrastructure. This article summarizes the evaluation results of the V2X tunnel experimental test, the outputs from the analysis of these blind spots, and it provides a future perspective and suggestions that make tunnels smart by using advanced positioning approaches.

The purpose of the presentation is to present intelligent transport systems (ITS) as a field integrating telecommunications and information technologies for control systems in the city and on highways, as well as from the point of view of using 5G networks for predictive diagnostics of faults in those systems. The requirements and needs of administrators of transport and technological infrastructure are mainly the optimization of operating costs and maintenance, which form a significant part of the financial costs after the introduction of ITS systems. Intelligent transport systems are often distributed over larger areas, from which you need to obtain not only basic control and information data in high quality, reliability and low latency, but also diagnostic data. An example can be obtaining traffic data from drones, information from light-controlled intersections, parking systems, but comparing data with the digital twin of the given traffic system or applying it to urban Mobility Hubs. This information and data from ITS lead to the processing of a large amount of transmitted data, where 5G fulfills the demanding requirements of customers and administrators of ITS technology. New trends in the extraction of data from real traffic and online diagnostics extended by predictive algorithms are beginning to be significantly applied in Industry 4.0, where faster transmissions in practice using 5G using simulation, system interconnection, visualization in add-on applications and their mutual interconnection and optimization lead to higher efficiency of activities for planning, determining the life cycles of equipment and fulfilling the needs of the circular economy. This knowledge is being successfully gradually adopted precisely in the transport systems. The application of 5G networks for diagnostics in ITS fulfills the essential needs for data transmission, the necessary data security and the necessary real-time processing that transmission technology can offer. The presentation approaches all these topics from the perspective of telematics systems that are used in transport and we encounter them every day not only in road and rail transport, but also in air and water transport.

The main aim of this paper is to present a new possibility for detection and recognition of different categories of electric and conventional (equipped with combustion engine) vehicles. These possibilities are provided by use of thermal and visual video cameras and two methods of machine learning. The used methods are Haar cascade classifier and convolutional neural network (CNN). The thermal images, obtained through an infrared thermography camera, were used for the training database. The thermal cameras can complement or substitute visible spectrum of video cameras and other conventional sensors and provide detailed recognition and classification data needed for vehicle type recognition. The first listed method was used as an object detector and serves for the localization of the vehicle on the road without any further classification. The second method was trained for vehicle recognition on the thermal image database and classifies a localized object according to one of the defined categories. The results confirmed that it is possible to use infrared thermography for vehicle drive categorization according to the thermal features of vehicle exteriors together with methods of machine learning for vehicle type recognition.

Automatic parking services can make a significant contribution to saving time, reducing emissions, increasing safety and increasing the mental well-being of drivers. Thanks to automated parking, it is also possible to optimize the use of parking spaces. The article deals with the issue of automated parking in urban areas. The aim is to present a proposal for the application of smart solutions in the form of a Mobility Hub for parking, along with subsequent control and enforcement that falls within the areas within Smart City. Mobility Hub is an important attribute for the future functioning of mobility. An integral part of the verification of parking options is the users' own interest in automatic elements in the vehicle and thus the connection to mobile applications, other systems, and involvement in the Mobility Hub for the use and sharing of information. The survey, the results of which are reflected in this article, examines the interest of potential users.

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".

The paper proposes a method for detection of a fire inside the road tunnel without direct view on the fire, using on-board vehicle technologies. The system is based on comparing the measured development of temperature and smoke with model scenarios precomputed for a given road tunnel. The fire scenarios are computed by HW/SW tool TuSim regarding the parameters of the real road tunnel and then the results are presented to the vehicles via car-to-infrastructure communication link. The proper detection of the fire allows early evacuation of the vehicle passengers, which will significantly increase chance of their survival. The computed scenarios also provide supporting information for the rescue teams.

Many modern vehicles today are equipped with an on-board e-call system that can send information about the number of passengers in the event of an accident. However, in case of fire or other major danger in a road tunnel, it is very important for rescue services to know not only the number of passengers in a given vehicle that has an accident and called help via e-call but how many people are in the tunnel in total. This paper deals with the issue of passenger detection and counting using the TPH3008-S Thermal camera and the VIVOTEK IP7361 IP Cameras noninvasively, i.e., the cameras are placed outside the vehicle. These cameras have their limitations; therefore, we investigated how to improve conditions and how to make detection better for future work. The main goal of this article is to summarize the achieved results and possibilities of improvement of the proposed system by adding other sensors and systems that would improve the final score of passenger detection. The experimental results demonstrate that our approach has to be modified and we have to add additional sensors or change methods to achieve more promising results. The results, findings and conclusions might be later used in tunnels and highways and also be applied in telematics and lead to better, safer road transport and improvement of existing tunnel systems sustainability by utilizing resources in a smarter way.

The paper presents a draft of a possible detection and classification system of vehicle propulsion systems working with thermal analyses. The differences in thermal features of different vehicle categories were found out and statistically proved. The thermal images were obtained using an infrared thermography camera. They were utilized to design a database of vehicle class images of passenger vehicles (PVs), vans, and buses. The results confirmed the hypothesis that infrared thermography might be used for categorizing the vehicle type according to the thermal features of vehicle exteriors and machine learning methods for vehicle type recognition.

The article deals with the proposal of a methodology for identification and monitoring of traffic operators' fatigue level, with focus on the air traffic controllers. Many scientific methods of fatigue detection are not applicable in the traffic operators' environment due to significant disruption of the normal traffic operators' comfort. Research focuses therefore on a method of voice analysis that does not interfere with normal operation but has not yet been sufficiently scientifically verified. The currently realized project uses a scientifically validated EEG method for validating the voice analysis method for designing a voice analysis methodology for the purposes of identifying and measuring the current fatigue level of operators in traffic, specifically in the air traffic management environment but with potential for use in all modes of transport.

This paper describes predictive diagnostics used in a process of telematic systems maintenance focusing on the checkup and potencials for improvements in road tunnel constructions. For this we have chosen the tunnel constructions as the most suitable ones from the telematic systems as they contain huge amount of technologies, systems and subsystems. Tunnel constructions is from its nature complex system providing large amounts of data and many device status and other reports. Actual tunnel status is fundamentally influenced by the operation, the state of technological equipment and, last but not least, by the activity of the operators responding to emergencies, solving normal operation states and planned or operative maintenance. Each part of the tunnel technological equipment requires for its correct operation specific actions, which are planned as a coherent set of rules and operating regulations based on alarms from the technical equipment, evaluation of traffic data and operators' knowledge. This is also applicable to any telematics system that consists of several subsystems or is a larger system based on a distributed diagnostic system.

The article deals with the current issue of road traffic management in the urban area during an emergency, which can be triggered in the event of traffic congestion, extraordinary events, or other unexpected situations in the area. If this situation arises in the city, the aim is to propose meaningful traffic management solutions to decrease the impact of society-wide losses. The main requirements are then early identification and classification of the cause of the emergency, finding and quick application of a suitable alternative control solution and rapid ability to resume operations in the area of congestion restricted. The main idea of the research is the use of traffic lights in crisis management of transport. First the article carries out a review of current foreign solutions in the event of emergencies, then it summarizes the methodological proposal for the use of traffic lights in the Czech Republic in the event of emergencies. The proposal also contains a list of necessary legislative adjustments and changes in technical solutions of currently installed traffic lights. Finally, the methodical procedure is applied to a specific example of the urban area in Uherské Hradiště.

The prediction of traffic accidents in urban networks is one of the key future theme in the areas of traffic control and navigation. Early identification of the risk of a traffic accident can lead to an increase in the safety and smoothness of road transport. Neural networks belong to the expert methods for modeling of complex systems. The issue of their use in the transport sector is scientifically quite progressive. The article describes the design of prediction model based on available traffic data from town Uherské Hradiště. Traffic data was collected from many sources, e.g. junction detectors, meteorological stations or traffic accident portal. Appropriate parameters for the model were selected from the traffic data. The model was then tested on a 2-month data sample. The aim of the article is to confirm the suitability of using neural networks to predict traffic accidents

Problems of the stationary traffic are solved today by almost every larger town. Most of the towns suffer from an insufficient number of parking spots in the street network. It is at the same time very complicated and economically demanding to create new parking areas, so the towns try to use the existing parking areas as efficiently as possible. The objective is thus to apply systems and technologies for efficient use of existing parking spaces, and also to monitor parking occupancy, distribute information to drivers, and apply various payment systems (parking meters, SMS payments an mobile applications) in order to facilitate the collection of payments from drivers. Within Smart City applications, it is necessary to consider not only parking aspects but also organisational aspects. Installation of Smart parking components is senseless, unless these components are accepted by user/driver and unless continuous traffic surveys are performed oriented in parking checks in the town.This article monitors the course and results of an extensive traffic survey oriented mainly in respecting the parking rules. In the centre of Uherské Hradiště, there are many specific parking spaces, 3 major paid parking zones, designated spaces at selected institutions, designated spaces for time-limited free parking, etc. The article describes in details the experience from the traffic survey oriented in respecting the parking rules in the town and subsequently proposed measures and suggestions how to make the existing state in the town more efficient with respect to the Smart City concept.

This article describes the results of using new approaches in the implementation of intelligent road traffic control algorithms applied in smaller city areas. As a solution of designed traffic-dependent model was the application of different data from the sensor network, which have and can impact on increasing throughput of fully loaded roads in the city but also makes traffic behavior more accurate in the defined area with wider overhead for controlling. The systems outputs optimize traffic parameters of the defined node as well as interconnected intersections with traffic lights and other subsystems according to the traffic situation in the wider area. The article describes not only methodology but also general recommendations that are the result of experience in testing and deploying of adaptive traffic control algorithm in real conditions.
