摘　　要：平交路口远引是解决路口流向禁限后车流转向问题的有效方法。通过对掉头地点的选址规划以及交叉口之间的协调控制进行研究,提出最佳掉头位置应满足的条件以及交叉口协调控制的相位差计算方法。通过对掉头通道通行能力的分析,提出实施掉头信号控制条件和具体实施方法。Indirect left turn with U-turn at intersection is one of effective measures to solve vehicle turns after restricting turns at intersection. This paper focus on location of u-turn median opening and coordinated control of upstream and downstream signalized intersection. A working model was developed to guide u- turn median location and offset of upstream and downstream signal timing. The condition and measure of signalized control at the median u-turn opening were pointed out by analyzing the capacity of u-turn at the median u-turn opening.
