基于VISSIM仿真的城市道路交叉口优化设计

Optimization of Urban Road Intersection Based on VISSIM Simulation Software

城市道路交叉口是各类交通汇合、转换的地点,是组织道路交通的控制点。通过对平面交叉口存在的主要问题的分析,提出了以交叉口渠化以及信号控制为重点的优化设计方案,并以案例研究为依托,结合VISSIM软件仿真,对交叉口改善前后的通行效率进行对比,论证了平面交叉口优化设计内容的可行性。

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- 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.
