摘要
交叉口合理的信号配时对车辆的运行有很大影响,本文以西安市五路口为研究对象,该交叉口在地铁四号线在建范围内,道路围挡使原本交叉口的信号配时有待优化。为了使信号配时得到合理优化,结合实地调查情况首先对交叉口车辆运行现状进行分析,找出信号配时存在的问题,并结合信号配时模型对信号配时进行优化,进一步利用Vissim仿真对配时前后车辆延误、停车次数等进行对比,以图形形式直观地给出优化方案的评价结果。
Reasonable intersection signal timing has a great influence on the operation of the vehicle. In the paper Wu Lukou of Xi＇an, which is in the scope of under construction in the subway line 4, was taken as research object. Because road is closed, originally inter- section signal timing need to be optimized. In order to make the signal timing achieve optimization, combined with field investigation, first of all, vehicle running status are analyzed in the intersection, and the problems about signal timing are found out, next the signal timing is optimized considering with the signal timing model. Finally, traffic simulation software Vissim is used to evaluate the running status of before and after optimization, and evaluation results of optimized scheme are put forward.
