摘　　要：针对城市交叉口存在的早晚高峰段交通流分布不均衡现象,为避免道路资源的浪费,提出在交叉口进口道设置逆向可变车道,利用信号灯的相位控制逆向可变车道的开闭,以缓解交通拥堵。并以淄博市张店区某一交叉口为研究对象,结合已有理论对逆向可变车道的长度、开闭时间及附属设施进行研究,具体阐述逆向可变车道的设置方法。基于Vissim仿真技术结果表明:设置逆向可变车道后该交叉口左转车辆的延误时间减少了34.2%,最大排队长度减少了41.5%,一个信号周期内通过的车辆数增加了67.6%。In view of the unbalanced traffic flow distribution in the morning and evening rush hours at urban intersections,in order to avoid the waste of road resources,a reversed variable lane is set up at the intersection entrance,and the reversed variable lane is controlled by the phase of signal lamp to alleviate traffic congestion.Taking an intersection of Zhangdian District in Zibo City as the research object,combining with the existing theory,the length,opening and closing time and auxiliary facilities of the reverse variable lane are studied,and the setting method of the reverse variable lane is expounded.The simulation results based on Vissim show that:after setting reversed lanes,the delay time of left-turning vehicles at the intersection is reduced by 34.2%,the maximum queue length is reduced by 41.5%,and the number of vehicles passing through a signal cycle is increased by 67.6%.
