Abstract:Operation bottleneck diagnosis is of great significance to bus schedule adjustment and vehicle scheduling optimization. Based on 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. In the enterprise operation efficiency of bus, bus passenger travel based on the analysis of the factors such as efficiency, respectively from the aspect of site bus is put forward the headway, vehicle delay degree evaluation methods, such as, at the line level build bus travel time and transportation efficiency evaluation method, and based on the site, track line network level comprehensive analysis method of evaluation results. 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.
