Using intelligent transport systems in cities is gaining popularity. The fundamental aim of their existence is to improve safety and traffic flow and prevent congestion in city centres. All people moving around the city, such as public transport passengers, as well as truck and emergency vehicle drivers and drivers of passenger vehicles, are users of intelligent transport systems. Research which was carried out for the article entirely concerns functioning and utility of intelligent transport systems from truck drivers’ experience. The main aim of the research was to evaluate services and tools within intelligent transport systems in European cities which are visited by Polish truck drivers. Our research indicates that most drivers (almost 98%) stated that they find intelligent transport systems useful and 92.5% of interviewed pointed that intelligent transport systems help with their everyday work duties. Of all the tools in the survey drivers agreed that variable content signs, accommodative traffic lights, and extra road illumination have most influence in road safety. Identifying the most useful and helpful tools of intelligent transport systems will allow to define their preferred development directions from truck drivers’ point of view.

AbstractThis paper is concerned with the assessment of future applications of CASE (Co-operative, Autonomous, Shared, and Electric) mobility—a term that is also taken to include the more traditionally known applications of ITS (Intelligent Transport Systems). It sets the objective of making such assessments more holistic and horizontal in nature because future CASE mobility applications will include many technologies and service concepts as an integrated whole serving specific mobility objective. Traditional evaluation methodologies will therefore have to be modified to account for this situation, and to this end, the paper focuses on assessing and adapting such “traditional” methodologies. It draws from the experience gained in Greece in the last decade when a substantial number of ITS applications were implemented and assessed, especially in the second largest urban area of the country, the city of Thessaloniki (part of the EU’s European Network of Living Labs). Four basic methodologies are selected: the use of KPIs (Key Performance Indicators), focused interviews, the CMME (CASE Mobility Matrix Evaluation), and the use of safety audits before and after the CASE mobility application. For the first three, the paper suggests specific indicators and/or content. It also gives an example of the use of CMME based on a use case from Thessaloniki. The contents and recommendations of this paper provide a better understanding of the emerging situation as regards CASE mobility applications and point to the need for establishing a timely and comprehensive CASE mobility evaluation framework at both national and European levels, for future implementations.

The Intelligent Transport Systems (ITS) wireless infrastructure needs to support various safety and non-safety services for both autonomous and non-autonomous vehicles.The existing wireless infrastructures can already be used for communicating with different mobile entities at various monetary costs.A packet scheduler, included in a shim layer between the network layer and the medium access (MAC) layer, which is able to schedule packets between uncoordinated Radio Access Technologies (RATs) without modification of the wireless standards, has been devised and its performance evaluated.In this paper, we focus on the influence of mobility type in heterogeneous wireless networks.Three cases are considered based on the mobility in the city: walking, cycling, and driving. Realistic simulations are performed by generating mobility traces of Oxford from Google Maps and overlaying the real locations of existing WiFi Access Points. Results demonstrate that the shim layer approach can accommodate different user profiles and can be a useful abstraction to support Intelligent Transport Systems where there is no coordination between different wireless operators.

The article presents threats related to broadly understood cybersecurity, encountered in modern public transport, especially in cases of increasingly introduced Intelligent Transport Systems (ITS). Experience to date has shown strong links between the technical sphere and IT system of public transport, ensuring its protection against unwanted externa l interference from people (or organizations) trying to disrupt its functioning. The following - inter alia - are of a key importance: the system of existing bus network as well as organization of bus work on routes (schedule) and its IT links, monitoring and system protection against external interference. The main goal of cybersecurity in public transport is to increase the level of cybersecurity in city agglomeration by increasing the availability of hardware and IT tools, included in intelligent transport systems, protecting safety and reliability of operation of public transport.

By making changes in the regulations on road signs there should be specified a date for which the road manager should adapt an existing signs. The existing rules significantly changed the rules for the use of road signs. Some of these modifications concerned the traffic lights. According with that document these changes should be made up to 31 December 2008. As seen in Polish cities, not all managements have managed to adjust the traffic lights to the new rules. The following article presents results of analyzes to adapt 45 traffic lights to the current rules. Those traffic lights were redesigned to create Intelligent Transport Systems in Bydgoszcz.

This article is devoted to the process of modeling dynamic systems of city intelligent transport systems (CITS) with the help of information technologies. The proposed means of fundamentally new integrated subsystems CITS, simultaneously covers arrays of heterogeneous data and use modern neural network technologies to provide information support for the management of transport systems. The safety of the ecological state as a result of the influence of urban traffic in the conditions of industrial centers was formalized for information technologies. Descriptions are executed as mathematical models of complex particles of objects of the city intellectual transport network with the use of heterogeneous fragments. Strategies and methods of systematic management are analyzed for solving complex problems of reducing the ecological load of the city. Ontological descriptions in basic model forms that are focused on ensuring the safety and ecology of urban applications to overcome contamination, risks and threats. This direction involves the creation of systems for automated management of transport infrastructure, which at the moment requires the solution of a range of scientific and technical tasks.The built-in neural network models of dependence will effectively solve planning problems with controlling influences on the infrastructure of urban intelligent transport systems, which will improve the characteristics of the traffic flow and reduce the environmental burden on the environment. The analysis of transport infrastructure and the activities of organizations that have a direct influence on it, has allowed us to propose a scheme for the use of heterogeneous information in the information support of the management of environmental safety and the throughput of the street-road network of urban intelligent transport systems. Keywords: information technology, transport system, situational management, risks, models of the situation.

Intelligent City

Road congestion has become one of the major problems of urban cities due to the growth in the number of vehicles and the limitation of road infrastructure. The consequences of this congestion can be seen through a difficult movement of vehicles, an increase in CO2 emissions, increasing energy consumption, and stress for drivers. Intelligent Transport Systems (ITS) based on wireless sensor networks (WSN) have emerged with new solutions and application potentials in the context of the Intelligent city.  In this article, we study an approach of using a wireless sensor network to control the traffic lights of several intersections and optimize their performance by reducing the average waiting time of users. the proposed adaptive traffic light controller determines the traffic lights sequence in real time based on the current traffic situation at the local intersection, the expected arrivals and the degree of congestion at destination intersections. To evaluate our approach, we construct an intersection network of twenty-four intersections with high traffic intensity using the SUMO simulator, the results of the simulation demonstrate the efficiency and practicality of the proposed algorithm.

Current challenges in mobility and sustainable development are closely related to increasing travel safety, optimizing the use of transport infrastructure, reducing operating and maintenance costs and making public transport more attractive. The proposed solutions to these major challenges depend to a high extent, on political decisions, development of good practices, and also on the innovation and technology introduced through on-going Intelligent Transport Systems (ITS) programs and initiatives. This chapter provides an overview on the communication architectures able to support these ITS programs. In order to do so, this chapter presents the current standardization initiatives in the vehicular environment, a description from the telecom point of view of the different ITS services, and finally, a survey on the radio access technologies capable of dealing with such a demanding scenario.
