有轨电车平交路口停站方案对延误时间的影响

有轨电车的站台一般设于道路平交路口附近,其形式以岛式、侧式站台为主。不同的站台布置形式对应不同的停站方式,其产生的延误时间也不同,而延误时间与信号周期、绿灯时长、平交路口宽度、发车频率、停站方式等因素有关。结合算例对分离岛式站台两种停车方案的运行过程及延误时间进行了计算分析,利用概率论的观点理论上证明了分离岛式站台采用上游停站方案平均延误时间比下游停站方案少。

Influence of Modern Tram Intersection Stop Strategy on the Delay Time

Modern tram platform is usually set up near a road intersection, and adopts mainly the island type and side type forms. Different platform types correspond to different stop modes and delay times,and the latter are relevant with signal cycle,the length of green light, the intersection width,service frequency and stopping mode. Combined with practical calcu-lations,two stopping modes at the isolated island platform are analyzed,including the tram operation and delay. Finally, based on the probability theory,the average delay time of iso-lated island platform (side) that adopts upstream stop strategy is proved shorter than that of the downstream stop strategy.
