摘　　要：为了分析设置逆向可变车道对交叉口拥堵治理的效益,以通行能力、车辆延误及排队长度作为交叉口逆向可变车道交通效益的评价指标,并建立数值计算模型。结合实际案例,采用VISSIM仿真软件对逆行可变车道设置前后,交通效益指标进行对比分析。结果表明,逆向可变车道的设置使交叉口通行能力提升了26.00%,平均排队长度下降了46.34%,最大排队长度降低了39.42%,车辆停车次数减少了25.00%,平均延误降低了16.61%,平均停车时间减少了18.92%。由此可见,逆向可变车道的设置对缓解交叉口交通拥堵,提高服务水平效益显著。In order to analyze the benefits of setting reverse variable lanes on congestion management at intersections,capacity,delay and queuing length are used as evaluation indicators of traffic efficiency of reverse variable lanes at intersections,and a numerical calculation model is established.Combined with actual cases,VISSIM simulation was used to compare and analyze the traffic efficiency indicators before and after the setting of retrograde variable lanes.The results show that the setting of reverse variable lanes increased the capacity of the intersection by 26.00%,the average queue length decreased by 46.34%,the maximum queue length decreased by 39.42%,the number of vehicle stops decreased by 25.00%,the average delay decreased by 16.61%,The average parking time was reduced by 18.92%.It can be seen that the setting of reverse variable lanes has significant benefits in alleviating traffic congestion at intersections and improving service levels.
