公交车中途停靠站停靠能力及设计站长计算初探

本文主要分析了影响公交车中途停靠站的停靠能力的诸多因素,从中选出相互独立的四个影响因素,即在站消耗时间、公交车到达率、站长和路段交通状况,由这四个影响因素引出四个量化的变量,即平均停靠车辆数、在站平均消耗时间、公交车流量、路段机动车流量,来研究设计站长的计算模型。拟定调查方案,对南京市市中心区典型的14个公交车中途停靠站进行调查,对数据进行统计处理,得到关于以上四个变量的14个样本。分别进行非线性和线性回归分析,得到两组计算公式,且统计检验结果表明拟合很好,可以用来计算设计站长。

THE STUDY OF THE PARKING CAPABILITY AND DESIGN LENGTH OF PARKING SPACE OF BUS STOP

The paper analyses many factors that influence the parking capability of bus stop. Four separate influential factors are selected from them, such as bus spending time at bus stop, bus arrival rate, length of parking space and road traffic status. Four corresponding quantified variables are average parking vehicle number, average bus spending time at bus stop, bus flow and road traffic flow. They are derived from four influential factors to establish the compute model of the design length of parking space. Studied out the survey plan and carried it out at fourteen bus stops in the center district of Nanjing city. Handle the data by Stat. to get fourteen samples about these four variables. Two compute formulas are gained from separate linear and non-linear regressive analysis and the coefficient of determination R2 indicates the degree of fitting is high. They can be used to determine the design length of parking space of bus stop.
