Abstract

The use of information technology in traffic management can increase the capacity of traffic intersections and reduce vehicle delays. In cities, adaptive traffic control at traffic lights intersections has been well established. Adaptive regulation is applied mainly on isolated traffic lights, where the traffic flow has a predominantly exponential distribution of intervals. It was established experimentally that the effectiveness of the method decreases with a supersaturated traffic flow, which makes it difficult to find a “cutoff point”, a convenient moment for switching the traffic light signal. The article shows that at isolated multi-band intersections, the search for a convenient signal switching time is difficult at low loading levels. At uninsulated intersections, the incoming flow will have clear periods of time without vehicles, which makes the operation of adaptive traffic control in these conditions at a multi-lane crossing more efficient. This suggests the need for further study of the patterns of distribution of intervals between cars in urban environments at the approaches to non-isolated intersections and at the approach to intersections operating without coordination with other traffic lights.

Highlights

  • At present, the development of transport infrastructure is not the construction of new road junctions and not the expansion of roads, but the search for more advanced road traffic management options, including the introduction of information technologies and intelligent transport systems

  • The organization of traffic mainly relies on the use of adaptive control of traffic lights, adapting to the changing parameters of traffic flows [2]

  • The transport infrastructure and methods of its organization should be harmoniously developed within the framework of the “Livable Cities” concept [3]

Summary

Introduction

The development of transport infrastructure is not the construction of new road junctions and not the expansion of roads, but the search for more advanced road traffic management options, including the introduction of information technologies and intelligent transport systems. This is the distribution of transport navigation systems on city streets, the introduction of automated traffic control systems, the synchronization of their data with the data of GPS navigators [1]. These systems include the Spektr 2.0, SCOOT and UTOPIA motion control systems
