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.

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

Crisis traffic management is one of the current topics that current cities are addressing within the Smart City concept, as a properly set-up system should serve to increase the safety and fluidity of traffic and reduce driver delays on the road network. This paper focuses on the investigation of the design of a new crisis management system using traffic lights in the simulation program AIMSUN NEXT by comparing three basic scenarios with similar inputs. Based on the evaluation of the measurable parameters, it can be concluded that the proposed crisis management system helps to reduce the total delay of vehicles in the network and also the total number of stops of individual vehicles in the network. However, the specific limits and expected inputs to the crisis management system need to be taken into account, which is discussed in this paper.

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.

As part of the implementation of the Smart City concept in cities, there is an effort to use efficient, economical and sustainable solutions that should contribute to increasing the quality of life in cities. LoRaWAnis one of the IoT technologies that offers a solution for wireless data transmission, when the main goal is low energy consumption at low acquisition costs. Cities are currently building this network, but they often do not have a clear purpose in advance for its versatile use. The aim of this review paper is mapping the possibilities of using the LoRaWAnnetwork for (not only) Czech cities. First, it analyzes and describes the current state of knowledge in the field of LoRaWantechnology, then, based on examples of good practice from various cities across the several countries, it defines the areas of use of the LoRaWannetwork for streamlining processes in cities, and then gives specific examples of elements - sensors that can be used in the LoRaWannetwork. Finally, we propose specific recommendations on the example of a case study for Hradec Králové, which is a medium-sized city in the Czech Republic that currently has a LoRaWannetwork built. All the recommendations are in line with the concept of sustainable mobility and the SMART Hradec Králové project.

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.

In the context of nature protection, there is an effort to regulate individual car traffic in protected areas. In the framework of the research, a pilot testing of a vehicle detection and identification system in the Krkonoše National Park was carried out using two selected technologies (license plate recognition and Bluetooth token detection). The research was carried out under conditions of poorer availability of mobile signal for transmission of measured data, lack of electrical power supply, and in challenging climatic conditions in the mountains. The main objective was to verify the applicability and limits of the mentioned technologies under these difficult conditions. For this purpose, two test sites were built: a fixed and a mobile point. Testing at both points was carried out using two basic methods, namely online through continuous data collection from the detectors and on-site through a local survey during the summer of 2022. The parameters evaluated were the reliability of the vehicle identification itself and the reliability of the operation of the individual detection subsystems and the tested system as a whole. The results show that the license plate recognition system using two cameras for the checkpoint shows a high recognition reliability, but it is reduced for some types of vehicles (especially motorcycles and four-wheelers). At the same time, this technology is demanding on energy resources. Detection using a Bluetooth scanner has proven to be highly reliable up to 50 km/h. A reliable power supply is necessary to achieve high reliability, which was a problem at the mobile point. Evaluation of images from cameras with motion detection showed the limits of this technology, which increased with increasing vehicle speed. The system can be used to detect traffic in protected areas, taking into account the limits specified in this article.

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.

Almost every city deals with the problem of lack of parking spaces. Vehicles looking for a place to park cause noise and pollution. Appropriate parking regulation can increase safety for all residents, save drivers time and money, save the City funds, and have a positive impact on air quality in the City. There are many different approaches to parking management, one of the simplest is to adjust the amount of parking fees. This paper deals with a general proposal for dynamic parking regulation based on variable pricing and what it should be based on. The aim of real-time dynamic parking regulation is to evenly distribute vehicles. The main idea of the research is to propose the use of financial motivation of drivers to optimize parking. The aim of this paper is to present a proposal for real-time variable-price parking regulation.
