Optimization of Signal Timing for Urban Intersection Based on Vissim——Taking “Yue Hai Men Cun” Intersection for Example

Because of the frequent interferences among vehicles and signal timing are unreasonable,the average vehicle delay time and traffic capacity of signal control intersection cannot meet demands. TakingYue Hai Men Cunintersection for example,this paper applied the equivalent traffic improved signal timing program in optimization of signal timing based on a traffic flow survey.Using Vissim software to establish a traffic simulation,this paper analyzed the intrinsic signal timing and proposed signal timing.The results of the simulation indicated that the delay time of vehicles degreased 16.6%,the time of stop degreased 19.3%,the average he queue length degreased 10.6% and the traffic volume increased 2.4% in proposed signal timing model.
