基于概率统计模型的公交停靠站车流特征分析

Study on Bus Traffic Flow Character at Bus Stops Based on Statistical Model

公交停靠站是城市公共交通系统的重要组成部分,公交停靠站不仅关系到公共交通运输的质量和效率,而且影响公共交通的运行质量和城市环境。本文采用人工计数法对哈尔滨市东大直街公交停靠站的公交车到达时间、服务时间、机动车流量进行统计,运用数理统计法整理调查数据,采用概率统计模型拟合了公交车辆到达和服务时间的分布特性,给出了分布拟合函数。

Bus stop is an important component of urban public transport system. The optimization design of the bus stop produces an effect not only on the quality and efficiency of the public transport, but also on urban environment. The paper makes statistics on bus arrival time, stopping time and traffic flow at Dong-da-zhi Street Stop in Harbin by human counting, makes data reduction with mathematical statistics, fits the distribution character of bus arrival time and stopping time by probability statistics, and provides with distribution fitted function.
