地铁占道施工对交叉口通行能力影响分析研究

Analysis of the Impact of Subway Work-zone on Road Intersection Capacity

通过分析交叉口地铁占道施工对交叉口通行能力的影响,对交叉口提出采用单进口的放行方式代替原有对称放行方式来弥补车道数不足的方法,分析优化前后交叉口通行能力并进行比较。最后,以南京市北京西路与虎踞路交叉口为例,利用VISSIM软件进行仿真,通过车辆的平均延误、车辆的平均排队长度、停车率三个参数来衡量优化前后交叉口通行能力,结果表明,优化后的交叉口通行能力有很大程度上的提高。

Through the analysis of the intersection of subway lane construction influence on intersection capacity,to make up for the lack of lane number,the method of each phrase was used for an entrance instead of a method for symmetry phase design to analyze and compare the capacity of the intersection before and after the optimization. Finally,taking example of Beijing road and Huju road intersection in Nanjing,VISSIM software was used to simulate,through the average delay of vehicles,the average queue length of vehicles,parking rate of three parameters to measure the intersection capacity before and after the intersection optimization. The results show that the optimum intersection capacity is greatly improved.
