基于VISSIM交通仿真的交叉口信号配时优化研究

Research on Signal Timing Optimization of Intersection Based on VISSIM Traffic Simulation

城市信号交叉口拥堵问题一直是制约路段整体通行效率的主要因素。本文以昆明市日新中路与前卫西路交叉口为例,根据交叉口高峰时段交通流量调查数据,通过实用信号周期法与Webster算法两种方法对交通配时进行优化,并利用VISSIM交通仿真软件对优化前后的交叉口进行模拟分析,论证交叉口配时优化的可行性。

The problem of congestion at urban signalized intersections has always been the main factor restricting the overall traffic efficiency of the road section.In this paper,taking the intersection of Rixin Middle Road and Qianwei West Road in Kunming as an example,according to the traffic flow survey data during the peak hours of the intersection,the traffic timing is optimized by the practical signal cycle method and the Webster algorithm.This paper uses VISSIM traffic simulation software to simulate and analyze the intersection before and after optimization,and demonstrate the feasibility of intersection timing optimization.
