为了给公交线路车辆调度提供重要参数及给公交运营管理和居民公交出行提供决策依据,应用车辆自动定位系统数据对公共交通运行时间可靠性进行了分析.基于对公共交通运行时间的统计分析,提出变异系数、分布宽度、运行速度、堵率、规划时间、预留时间等6个指标,构建了公共交通运行时间可靠性评价分析框架.苏州市某公交线路实例分析结果表明,所提出的评价指标体系简单直观,能有效反映该线路公交车辆运行的效率和稳定性,且公共交通运行时间可靠性具有随不同时段变化的特征.

In order to provide important parameters for schedule designing, decision-making bases for transit operation management and references for passengers traveling by bus,bus transit travel time reliability is analyzed and evaluated based on automatic vehicle location (AVL) data.Based on the statistical analysis of the bus transit travel time,six indices including the coefficient of variance,the width of travel time distribution, the mean commercial speed, the congestion frequency,the platming time index and the buffer time index are proposed. Moreover, a framework for evaluating bus.transit travel time reliability is constructed.Finally,a case study on a certain bus route in Suzhou is conducted.Results show that the proposed evaluation index system is simple and intuitive,and it can effectively reflect the efficiency and stability of bus operations. And a distinguishing feature of bus transit travel time reliability is the temporal pattern.It varies across different time periods.
