摘　　要：运行瓶颈诊断对公交发车时刻表调整和车辆调度优化具有重要意义。从公交乘客和公交运营企业的不同关切点出发,结合公交GPS和IC卡等实时运营数据,提出一种公交运行瓶颈诊断方法。在公交企业运营效益、公交乘客出行效率等因素分析的基础上,分别从站点层面提出公交车头时距、车辆延误度等运行评价方法,在线路层面构建公交行程时间与运输效益评价方法,以及基于站点、线路评价结果的线网层面综合分析方法。最后,利用案例获取的公交车位置、行驶速度、公交乘客数量等实时数据,以及公交站点、线路、线网和调度方案等静态数据,对所提方法进行检验。结果表明,公交运行瓶颈诊断结果与公交实际运行状况具有较高符合度,能够实时、有效反应公交运行状态,具有较好的工程实用价值。Operation bottleneck diagnosis is of great significance to bus schedule adjustment and vehicle scheduling optimization.Considering the different concerns of bus passengers and bus operation enterprises,and combined with real-time operation data such as bus GPS and IC card,a method of bus operation bottleneck diagnosis is proposed.Based on the analysis of factors such as the operational efficiency of public transport enterprise and passenger travel,respectively from the aspect of site level,the evaluation methods of bus headway and vehicle delay are put forward,while the evaluation method of bus travel time and transportation benefit are constructed at line level,and a comprehensive analysis method of line network level is proposed based on the evaluation results of site and line level.Finally,the proposed method is tested with real-time data such as bus location,driving speed and number of bus passengers obtained from the case,as well as static data such as bus station,line,line network and scheduling scheme.The results show that the bus operation bottleneck diagnosis result has a high degree of conformity with the actual operation of the bus,and it can reflect the bus operation status in real time and effectively,and has good engineering practical value.
