考虑公交自行车的多层次公交协同调度研究

利用自行车实现公交线路之间换乘，可以有效扩大公交线路换乘范围. 实现不同层次公交线路间协同调度，可促进综合公交体系整体效益的发挥. 本文研究了考虑自行车换乘的、不同层次公交线路的协同调度问题，以乘客在线路间换乘的加权等待时间最小为优化目标，建立了相应的协同调度模型，基于遗传算法进行求解. 选取不同层次的实际公交线路，对所提协同调度模型进行仿真验证. 研究表明，所构建的协同调度模型及求解结果，能够有效缩短乘客在不同层次线路间换乘的等待时间.

Multilevel Bus Cooperative Scheduling Considering Public Bike

Using public bike for bus transfer can be an effective way to expend the service area of buses. The cooperative scheduling for multilevel bus lines would provide benefit for a comprehensive public transportation system. This study describes the concept of public bike, and then investigates the cooperative scheduling for multilevel bus lines considering the public-transportation bike. The cooperative scheduling model was developed with minimal weighted waiting time of passenger transfers. The genetic algorithm was used to solve the model. The effectiveness of the proposed model was verified by simulations with actual bus lines. The result indicates that passenger transfer waiting time was reduced significantly by using the cooperative scheduling model.
