Performances evaluation of the traffic control in a single crossroad by Petri nets

Abstract

Minimizing the queue length and vehicle delay time at crossroads is a major problem in the regulation of the traffic urban networks. This paper deals with two formal approaches based on Petri nets for a single crossroad. On one hand, these approaches make it possible to study the traffic behavior at crossroad in a microscopic point of view and in a macroscopic one. On other hand, the developed models provide a tool for the performance analysis of the different traffic signal's control. For this purpose, we show the performance indices of the vehicle interval control, which are obtained from simulation examples.
