Optimization of Urban Road Intersection Based on VISSIM Simulation Software

Urban road intersection is a convergence of various types of traffic and the control point of the traffic organization.In this paper,channelization method and signal control are proposed as the focus of intersect-ion optimization design based on the analysis of the existing problems of the grade intersection.Relying on case study and combining with VISSIM simulation software,the paper compares the traffic efficiency before and after intersection improvement,and demonstrates the feasibility of optimized intersection content.
