摘要
为增加提前进入交叉口停车线的车辆数,设置左转弯待行区的做法逐渐在许多城市平面交叉口中盛行。本文利用冲突点法[1],详细分析了左转弯待行区工作原理,解释了本向左转车辆与对向直行车辆通过冲突点附近时的相互关系,归纳了设置待行区的适宜条件。
To maximize the number of vehicles passing by the stop--line in a cycle, the settlement of left--turn lane Waiting one is becoming much prevailing. Based on conflicting--point method, this paper analyses the internal mechanism of left turn flow after stopping line. Meanwhile, a relation is expounded between the first left turn vehicle and the last opposing through vehicle front and back at the conflicting point.
