摘要
停靠站泊位设计合理性是衡量停靠站设计合理与否的重要标志之一,合理的公交停靠站泊位数对于提高道路通行能力、减少交通拥堵具有重要意义.以公交车辆到达服从柏松分布、车辆停靠时间服从正态分布为前提,分析了公交车辆停靠过程,给出了停靠时间、清空时间、运营时间裕量的计算方法.根据停靠站通行能力计算模型给出了有效泊位数和设计泊位数的计算方法.并对南坪公交停靠站分别按港湾式停靠站和直接式停靠站两种方式进行了泊位设计,得出按两种方式设计均需设3个泊位的结论.
The reasonability of bus stop berth is an important standard to scale the reasonability of bus stops,and the scientific setting for bus stop berth is useful to improve the traffic capacity and reduce traffic crowd.Firstly,it is supposed that the arrival of buses follows Poisson distribution and the stop time follows normal distribution respectively.Secondly,the stop process of buses is analyzed.In addition,the computing method about the stop time,the eliminate time and the spare work time is also given.Moreover,the computing method about the effective berth and designing berth is supplied according to the traffic capacity of bus stops.In the end,the berth design blueprint of harbor-shaped and roadside bus stops is given for Nanping bus stop,and the result shows that it demands three berths for the two cases.
