基于综合评价指标的公交线路时间控制点优选方法

为了合理设置公交线路的时间控制点，本文首先提出了设置时间控制点应遵 循的3 个原则，分别为站点流量较大、公交车辆运行时间差异较小、两个控制点不宜相邻； 之后考虑站点服务乘客数量、公交车辆行程时间差异、站点分布均匀性等因素构建服务 状态指标、站点分散度指标对3 个原则进行量化；基于熵权法确定两个指标的权重系数， 建立了综合评价指标计算方法，以及基于该指标的时间控制点选择流程.最后以哈尔滨市 63路公交线路为例对所建立的方法进行具体阐述.

A Method for the Selection of Bus Route Time Control Points Based on Comprehensive Evaluation Index

To set the time control points of a bus route more reasonably, three setting principles that should be abided are brought forward. They are stops with heavy volumes, minor difference among bus travel times and control points should not be adjacent stops respectively. Then considering the number of passengers serviced, the differences in travel times of the buses at the stops and the uniformity of the control points, the stop service status and control point uniformity are developed. These two indices can be used to quantify the three setting principles. The weighting factors of the two indices are determined based on entropy weight method. The comprehensive evaluation index is developed and then the selection flow for the time control points is constructed based on the index. Finally, route 63 in Harbin is taken as an example to explain the method developed in this paper.
