【摘要】：为了更为准确地计算信号控制交叉口通行能力,在HCM2010方法的整体框架下,针对交叉口上游直线式公交停靠站对通行能力的影响进行了研究。运用交通流理论,分析了在不同到达时刻条件下,单辆公交车停靠对所在车道绿灯损失时间的影响。在此基础上,运用概率论,分别建立了公交停靠站所在车道为直右共用车道、右转专用车道和右转与公交共用车道三种情况的交叉口通行能力计算模型,并对影响因素进行了敏感性分析。研究结果表明,公交停靠站与交叉口的间距以及公交停靠站所在车道的车辆到达率对通行能力起主要作用,实践中应保证公交停靠站与交叉口的间距能满足该车道红灯期间车辆排队长度要求。
[Abstract]:In order to calculate the traffic capacity of signal-controlled intersections more accurately, the influence of the upstream straight bus stop on the traffic capacity is studied under the framework of HCM2010 method. Based on the traffic flow theory, the influence of single bus stop on the green light loss time of the lane is analyzed under different arrival times. On the basis of this, using probability theory, the capacity calculation models of intersections in which the bus stop is in the right lane, the right turn special lane and the right turn and the bus common lane are established, respectively, in which the bus stop is in the right lane, the right turn special lane, and the right turn and the bus common lane. Sensitivity analysis of the influencing factors was carried out. The results show that the distance between the bus stop and the intersection and the vehicle arrival rate in the lane of the bus stop play a major role in the capacity. In practice, it is necessary to ensure that the distance between the bus stop and the intersection can meet the requirements of the queue length of the vehicle during the red light of the lane.
