摘要
公交调度是公交立体综合车场(简称立体车场)运营中的关键问题.不同于以往公交调度问题,立体车场公交调度需要同时安排各车的场内停车位置、发车时间与行驶路径.基于立体车场公交"早出晚进"特征对立体车场调度问题与调度模式进行研究,进一步分析立体车场公交车辆的交织条件;基于整数规划构建以立体车场公交车辆交织次数为目标的公交调度优化模型,求解立体车场公交调度方案.研究结果表明:立体车场公交调度存在同层集发和异层分发两种调度模式,且异层分发模式优于同层集发模式;此外,车辆交织条件是空间与时间同时发生重叠.通过案例验证了研究结论的正确性及调度优化模型的可行性.
Bus scheduling plays a key role on the operation of the stereoscopic and function-integrated depot(SFID or stereoscopic bus depot,SBD).Being different from previous bus scheduling,bus scheduling for SBD needs to determine the parking location,departure time,and driving path.This study focuses on the SBD bus scheduling considering the attributes of buses like departure in the morning and return at night.The condition of vehicle interweaving is also considered in the analysis.An optimization model is developed to solve the bus scheduling scheme based on the integer programming,and the weaving times between buses are set as the objectives of the model.The results indicate that there are two modes of bus scheduling for the SBD:the mode that dispatches buses at the same floor,and the mode that dispatches buses at different floors.The different-floor dispatching mode performs better than the same-floor dispatching mode.The interweaving condition is the doubleoverlapping of route space and out time.The case study was also conducted to verify the accuracy of the results and the feasibility of the proposed method.
