两种典型公交站点候车时间模型对比研究

乘客候车时间可直接反映公交运输系统的运营状态和服务水平.将常规公交站点分类为是否与轨道交通有衔接,对27路、111路白石桥东站,以及运通105路和87路城铁西直门站进行实地调研,获取各线路晚高峰的乘客候车时间数据,对数据进行拟合与分析.结果表明,客流到站时间分别服从对数正态分布和伽马分布.基于客流到站时间分布函数,反推出乘客候车时间模型,同时对模型进行对比分析,并得出相应结论.

Classification Comparing Research on Waiting Time Models of Two Typical Conventional Bus Stops

Passenger waiting time can reflect the operation of public transport systems and service levels directly.Waiting time models for different two categories of conventional bus stops have been proposed,a field survey on bus line 27,line 111,line 105,and line 87bus lines are conducted to collect the passenger flow data for these four lines during evening peak hour,based on these data,the passenger arrival time are analyzed,the results show that passenger arrival times obey lognormal distribution for conventional bus stops which is connected with the urban rail transit system and passenger arrival times obey gamma distribution for conventional bus stops which is not connected with the urban rail transit system.According to the distribution function of passenger arrival time,the passenger waiting time model for bus stop connected with versus without the urban rail transit system has been proposed.The differences between these two models are obtained,and draw corresponding conclusions.
