由于受上游交叉口信号控制的影响,高峰时间会有多辆公交车同时排队进站停靠,容易导致站点拥堵,影响车辆的正常运行.从受上游信控影响的公交车流的特性研究出发,采用排队论的方法,计算分析站点通行能力允许范围内的公交车辆发车频率与上游交叉口信控参数之间的协调关系.在公交优先的理念指导下通过对二者关系的研究提出减小站点拥堵的优化方法,并通过实例进行验证.%Under the condition of discrete flow, many buses come into bus stop simultaneously in rush hour, which result in interruption to vehicles in adjacent lane. Based on the research of traffic low influenced by signal control of upriver intersection, the paper analyzes the relation of bus service frequency attached bus station and signal parameters of upriver intersection by the method of queue theory. Meanwhile, an optimal method of deducing bus stop congestion is advised by research of the relation in guide of the idea of public transportation prior and a factual example is performed. So research of the relation provides a preference for the bus stop building and signal parameters designing of intersection.
