摘要
为了提高快速公交(BRT)系统的运行效率,对BRT停靠站在交叉口的布设位置进行了研究.针对BRT停靠站设置在交叉口进口道和出口道两种情况,分别建立了车均延误模型(该延误包括信号控制延误、停靠站上下客时间以及车辆在停靠站等候服务的延误)和绿灯末排队长度模型,并通过仿真验证了模型的准确性.一系列算例分析表明,车流量较小时,停靠站设置在进口道和出口道就延误而言没有区别,但当车流量较大时,应将停靠站设置在交叉口进口道.
In order to enhance the operation efficiency of the bus rapid transit （BRT） system, the optimal layout of BRT stops at intersections was discussed. Theoretical models were established for estimating the delay and queue length at the end of the green time with the consideration of signal control delay, dwell time and the waiting time for boarding and alighting service. Two scenarios of BRT stop locations, near- side and far-side bus stops were taken into account. The models were tested by VISSIM simulation. Results of extensive numerical analysis show that the position of the BRT stop has no effect on delay when the volume of BRT vehicles is low and the bus stops should be disposed at the intersection approach when the volume is high.
