基于VISSIM的北土城西路交叉口交通组织优化

VISSIM-based Traffic Organization Optimization of Beitu Chengxi Road Intersection

信控交叉口的渠化和信号配时直接影响交通的效率和安全。因此,如何对路口进行合理的渠化和信号配时使得车辆与行人安全、高效地通过信控交叉口具有重要意义。文章基于对北京北土城西路口相关交通数据的实地调查,分析了该路口存在的交通问题,并针对该路口的交通特性,使用交通仿真软件VISSIM对该信号交叉口进行了仿真研究,从路口渠化、信号配时等角度提出了三种优化设计方案。

The channelization and signal timing of signalized intersection directly affect the efficiency and safety of traffic.Therefora, how to carry out reasonable channeling and signal timing of the intersection so that vehicles and pedestrians can safely and efficiently pass through the signalized intersection has important significance.Based on the field investigation on the traffic data of Beitu Chengxi intersection in Beijing,this article analyzed the traffic problems existing at this intersection, then, re- garding the traffic characteristics of this intersection, it used the simulation software VISSIM to conduct the simulation research on this signalized intersection, and proposed three optimization design schemes from the aspects of intersection channelization and signal timing.
