摘　　要：左转交通流一直是城市道路交叉口中影响交叉口整体运行效率的关键,为了比较左转交通流不同组织方式对交叉口延误的影响,本文研究了专用相位左转和远引掉头左转两种左转交通组织方式下的车辆运行特性,并选取某典型交叉口为例进行基于Vissim的两种组织方式的实施效果评价。最终得出,在该交叉口情况下,采用远引掉头方式可明显减低车辆延误,提高交叉口运行效率。The left-turn traffic flow has always been the key to affect the overall operation efficiency of the intersection at the city road intersection.In order to compare the influence of the different transmission modes of the left-turn traffic flow on the intersection delay,this paper studies the special phase turn left and the Straight-U turn-turn right.Two kinds of left-turn traffic organization mode,and select a typical intersection as an example to evaluate the implementation effect of two kinds of organization based on Vissim.Finally,in the case of the intersection,the way of Straight-U turn-turn right can significantly reduce delays and improve the running efficiency of the intersection.
