The article is devoted to the prospects of improving the quality of traffi c in the junction of the urban street and road network through the introduction of intelligent transport systems, especially automatic traffi c control systems (ATCS). The paper analyzes the problems of implementing intelligent transport systems in urban conditions, taking into account the current regulatory framework. The classifi cation of local automated traffi c control systems according to the adaptability of traffi c light regulation to the changing parameters of traffi c fl ows is given. For the decision of a problem of practicability of introduction of ACSDS, the technique including construction of imitation models for more exact forecasting of eff ect of introduction of local ACSDS on the considered site of an urban street-road network is off ered. The application of the methodology is demonstrated on the example of the intersection of Engels Avenue and Suzdal Avenue in St. Petersburg. Two variants of the organization of control of phases of traffi c light objects are analyzed: static and adapted according to the time of day. The infl uence of ADCS implementation on average speed of vehicles and characteristics of traffi c jams in the junction in question was estimated based on simulation modeling in PTV Vissim. In accordance with the analysis, the prospects of introducing adaptive local ACSDS in the considered transport junction are described

Time Information

Advanced automatic traffic control systems and various other ITS (Intelligent Transport Systems) applications and services rely on real-time information from the traffic system. This paper presents the overview and general functions of different information sources which provide real-time information that are used or could be used in ITS. The objective is to formally define the quality of information sources suitable for ITS based on formal models of the traffic system and information sources. The definition of quality encompasses these essential factors: traffic system information that exists or may be requested, user requirements and attributes that describe the information sources. This provides the framework and guidelines for the evaluation of information sources that accounts for relevant factors that influence their selection for specific ITS applications. KEY WORDS: information source, information source quality, Intelligent Transport Systems (ITS), automatic traffic control

Bus Services

Applications of information technology are expanding rapidly across all modes of transport, under the general heading of intelligent transport systems (ITS). For bus-based public transport, a cluster of applications has been developed that can help improve the efficiency and performance of buses on the street, thus helping to provide a real transport alternative to the private car. An initial summary of a range of such ITS examples in Europe is provided, including automatic vehicle location (AVL), bus priority in traffic control systems, automatic ticketing systems, automatic camera enforcement systems, and variable message signs. Then the focus shifts to one area where activity is most pronounced—the implementation of AVL systems and their integration with urban traffic control (UTC) systems. A review of typical AVL/UTC systems operational in Europe is then presented through the identification of some eight alternative architectures and associated system characteristics, such as the technologies used and the location of bus priority “intelligence.” This is followed by a summary of examples from cities in Europe that have implemented these architectures, together with typical results illustrating the effectiveness of these systems. The diversity of architectures, technologies, and systems is recognized as beneficial in providing customer choice, but can generate a significant difficulty for decision makers in local authorities wishing to invest in public transport ITS technologies. A concluding discussion lists some of the key issues involved in this investment process.

The Road

The national project “Safe and high-quality roads” is aimed at the development, creation and effective use of intelligent transport systems. Today, there are many technical solutions to improve road safety, as well as optimize the process of organizing traffic. Often, these solutions lie not only in the plane of design, in the use of technical means for organizing traffic, in reconstruction of the existing street-road network, but also in the use of intelligent transport systems. The article has developed a concept for the development of a road-road network in Khabarovsk, in connection with the adoption by the Government of the Khabarovsk Territory of a decision on the construction of a transport interchange at the intersection of Voronezh-Bolshaya Streets in Khabarovsk, as part of the national project “Safe and High-Quality Roads” in the Khabarovsk Territory. The collection and analysis of statistical data, over a five-year period, on the types of frequency of occurrence of reported road traffic accidents. Visual and grapho-analytical methods identified the focus of the concentration of traffic accidents at the considered site of the road network of the city of Khabarovsk. Based on the method of conflict points, factors that influence the accident rate of an existing section of the road are studied. Several options for improving the quality and safety of traffic are considered: changing the number of lanes, regulating the traffic light, building a multi-level traffic intersection. Using modern software systems, based on methods of mathematical modeling, for several options developed models of traffic flows, identified the maximum possible comfortable and safe traffic conditions. Substantiated recommendations are given for improving the quality and safety of road traffic by improving the existing road situation.

Map matching algorithms integrate positioning data with spatial road network data to support the navigation modules of intelligent transport systems requiring location and navigation data. Research on the development of map matching algorithms has significantly advanced over the last few years. This article looks at different methods that have been adopted in map matching algorithms and highlights future trends in map matching and navigation research.

Abstract Extension of European Union causes increase of free transfer of people and goods. At the same time they raised the problems associated with the transport, e.g. congestion and related accidents on roads, air traffic delays and more. To increase the efficiency and safety of transport, the European Commission supports the introduction of intelligent transport systems and services in all transport sectors. Implementation of intelligent transport systems and services in the road transport reduces accident frequency, increases the capacity of existing infrastructure and reduces congestions. Use of toll systems provides resources needed for the construction and operation of a new road network, improves public transport, cycling transport and walking transport, and also their multimodal integration with individual car transport.

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.
