Критерий оптимизации параметров светофорного регулирования на улично-дорожной сети

Abstract

The digital transformation of the management of the transport complex and the growth of the pace of introduction of intelligent transport systems in the cities of the Russian Federation actualize the issue of finding a universal criterion for optimizing the parameters of traffic light regulation on the urban road network. In this article, as a criterion for optimizing network management, an average value of the travel time in the control area, weighted by the length of the path traveled, is proposed. The value of this criterion lies in the universality, as well as the fundamental technical feasibility of its calculation for a real section of the road network in terms of obtaining initial data. In addition, the article emphasizes the fundamental importance of determining this parameter for various conditions. In order to confirm the effectiveness of using the criterion considered in the article, a model experiment was conducted in the SUMO environment, involving a number of experiments for several control methods on the street network at different intensities of incoming traffic flows. On the basis of experimental data, the dependences of the proposed optimization criterion on control methods and the total volume of incoming traffic flows are obtained. The reliability of the criterion was evaluated. The application of the presented criterion in calculating the parameters of traffic light regulation allows you to select the optimal parameters and in the future provide feedback on the implementation of automatic traffic light control on the street and road networks of cities.
