摘要
为了解决信号交叉口进口车道功能固定分配方案不能满足各流向交通流的实时通行需求的问题,提出基于可变导向车道的进口道时空资源协同优化方法.以直行和左转方向车均延误最小为判别标准,作为可变导向车道功能是否切换的判断依据;设置预停车线、预信号与车道功能电子指示牌相结合的车辆诱导系统,并分别给出了预信号、电子指示牌信号与主信号间的切换时间差计算方法,引导直行和左转车辆按信号使用可变导向车道.以哈尔滨市黄河路某交叉口为例,利用Vissim软件进行仿真实验.结果表明:相比于现状情况下的交叉口控制方案,切换可变导向车道并进行信号配时优化的方案使交叉口车均延误降低了21.3%,说明采用时空资源协同优化方法对降低交叉口的车均延误有积极影响,提高了交叉口通行效率.
In order to solve the problem that the fixed allocation scheme of entrance lane function at signalized intersections can not meet the real-time traffic demand of all traffic flows,a collaborative optimization method of space-time resources of entrance lanes based on variable guide lanes was proposed.The minimum delay of vehicles in straight and left-turn directions was taken as the criterion to judge whether the function of the variable guide lane was switched.By setting the vehicle guidance system combining the pre-stop line,the pre-signal and the lane function electronic sign,the calculation methods of the switching time difference between the pre-signal,the electronic sign signal and the main signal were given respectively,so as to guide the straight and left-turn vehicles to use the variable guidance lane according to the signal.Taking an intersection in huanghe road,Harbin as an example,the simulation experiment was carried out by using Vissim software.The results show that,compared with the current intersection control scheme,the scheme of switching variable guide lanes and optimizing signal timing reduces the average vehicle delay at the intersection by 21.3%,which shows that the method of collaborative optimization of time and space resources has a positive impact on reducing the average vehicle delay at the intersection and is conducive to improving the traffic efficiency at the intersection.
