Vissim交通仿真软件在地铁施工交通影响分析中的应用

地铁施工对周边交通产生了极大的影响,以广州6号线长湴地铁站为例,在交通流量数据调查的基础上,利用Vissim交通仿真软件建模交通仿真模型,分析地铁施工对周边交通影响的情况,提出缓解交通拥堵的改善方案,并为后续地铁施工制定交通组织方案提供参考。仿真结果表明:改善方案使得长湴地铁站周边交通的车辆延误时间降低18.7%,停车次数降低26.2%,行程时间减少4.8%。

Traffic Impact Analysis of Subway Construction Based on Vissim Traffic Simulation Software

Subway constructions cause a great impact on the surrounding traffic.This paper used construction of the Changban station in line 6 subway in Guangzhou as an example,using Vissim software to establish a traffic simulation model based on a traffic flow survey,this paper then analyzed the surrounding traffic impact of the Changban station construction.Next it proposed a improved plan to ease traffic congestion,and this plan would provide a reference to develop transportation organizations,followed up by subway construction program.The results of the simulation indicated that the delay time of vehicles increased 18.7%,the number of stops increased 26.2%,and the travel time of vehicles increased 4.8%.
