Modeling and Simulation of Urban Traffic Network Using Colored Petri Nets

Management and control of vehicle traffic on the network of streets and cross-sections is part of urban traffic control system. The aim of this research is to propose an operations research method to model the urban traffic control system, in order to be used in improving urban traffic. Scientific contribution of this article is on the policy setting in scheduling traffic lights in lubricating urban traffic flow using colored Petri nets. In this research, Colored Petri Nets is used as a modeling and improvement tool. Part of Bushehr urban traffic network is modeled using the proposed method. In order to investigate different improving scenarios, discrete event simulation is applied. Results show that the proposed method is a suitable technique to improve the performance of urban traffic system. Based on the system performance measures, a suitable setting is proposed to improve the traffic flow.
