双港湾式公交停靠站容纳线路能力分析

Analysis of Route Capacity for a Double Harbor-style Bus Stop

为了缓解因停靠站公交线路数过多而造成的拥堵,提出双港湾式公交停靠站。本文首先详细说明了双港湾式停靠站的平面形式设置,然后从常规港湾式停靠站的停靠线路数入手,运用排队理论分析常规港湾式停靠站容纳线路能力,得出其不适用于线路数较多的情况,并与常规港湾式停靠站通行能力进行对比分析,得出其可以有效降低停靠站的排队概率,适用于公交车流量大、线路多的主干道。最后利用排队理论给出了双港湾式停靠站停靠线路数的推荐值。

In order to alleviate bus congestion duo to too many bus routes inastop, adouble harbor-style bus stop was put forward. The article gave a detailed description about the form of the double harbor-style bus stop by comparing with the number of the bus routes in a normal harbor-style bus stop and analyzing the route capacity of a normal harbor-style bus stop using the queueingtheory. Through the comparative analysis of the capacity withthe normal harbor-style bus stop, we concluded that the double harbor-style bus stop could effectively reduce the queueing probability and was suitable for urban arteries with lots of bus routes and high bus volumes. Finally, based on the queueingtheory, the recommended bus routes of the double harbor-style bus stop were given.
