Simulation-based Traffic Organization Optimization for Irregular Intersections

At irregular intersections there are usually more conflict points and traffic safety problems.Traffic organization and management of irregular intersections is,in general,more difficult.This paper firstly analyzes the main features and problems of the irregular intersections and summarizes the optimization methods for traffic organization at the irregular intersections.Then,it uses the intersection of Weiguo road-Beixin Road-Jianhua West Road in Tangshan City as an example and evaluates the implementation effect of the implemented schemes with a traffic simulation software Vissim.This paper concludes that such traffic organization optimization methods as traffic channelization,traffic signal control,and changing the intersection to a regular one,can significantly improve traffic movements and increase its efficiency.
