The article is devoted to the prospects of improving the quality of traffic in the junction of the urban street and road network through the introduction of intelligent transport systems, especially automatic traffic control systems (ATCS). The paper analyzes the problems of implementing intelligent transport systems in urban conditions, taking into account the current regulatory framework. The classification of local automated traffic control systems according to the adaptability of traffic light regulation to the changing parameters of traffic flows 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 effect of introduction of local ACSDS on the considered site of an urban street-road network is offered. 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 traffic light objects are analyzed: static and adapted according to the time of day. The influence of ADCS implementation on average speed of vehicles and characteristics of traffic 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.
