Study on traffic control simulation system based on VISSIM

Based on the problem of the current shortfall for urban traffic simulation system,in order to ensure smooth traffic to the adoption of the intersection to reduce vehicle collisions and other safety problems occur,a research design of multi-junction traffic control simulation systems is present.This design,which is based on the traffic flow simulation technology of VISSIM to analyze control system of traffic flow,realizes traffic control system simulation in the successive intersection.The results show that: it can effectively improve the accuracy of the simulation parameters and reduce the error rate test simulation,so that under different circumstances the control of traffic lights has good improvement.
