Abstract: Based on the traffic characteristics of the residents around the city and the contradiction between the bus operation cost and the passenger waiting time, a bus flexible scheduling system based on the Internet technology and the idea of network car-hailing was proposed. The operation mode of the flexible bus scheduling system was expounded, and the overall structure, module function and workflow of the flexible bus scheduling system were designed. The departure time of off-peak hours was determined by constructing a flexible departure interval function based on the number of passengers ordered, and the shortest path of response time and the comprehensive benefits of passengers and buses were calculated by using the flexible scheduling decision support model. Finally, taking180 road bus in Chongqing as an example, the comparison analysis between three appointment ratios of flexible scheduling mode and traditional operation modes was carried out. It is concluded that the flexible bus scheduling system can reduce the waiting time of passengers and the operation cost of public transportation.

摘要： 基于城市外围居民出行的交通特点以及公交车运行成本与乘客等待时间之间的矛盾，提出了基于互联网技术和网约车思想的公交柔性调度系统，阐述了柔性公交调度系统的运行方式，设计了柔性公交调度系统的总体结构、模块功能以及工作流程。通过构建基于预约乘客数量的柔性发车间隔函数来确定非高峰时段的发车时间，利用建立的柔性调度辅助决策模型规划出响应时的最短路径以及计算乘客和公交车的综合效益。最后选取重庆市180路公交为例，用柔性调度模式的3种预约比例与传统运行模式进行对比分析，得出柔性公交调度系统能减少乘客的等待时间，降低公交的运营成本。
