摘要
随着城市群、都市圈的逐渐形成,市域铁路与地铁的贯通运营在未来轨道交通的规划建设中需要广泛考虑,其不仅能够为乘客提供直达的便利,还能够降低运营成本。为了满足跨区出行的通勤客流需求,提高乘客的直达率,并通过采用编制周期运行图以减少运营公司的工作量,需要对市域铁路与地铁贯通运营下的列车周期运行图与车底周转计划进行一体化优化。以最小化列车总旅行时间、列车总折返时间、均衡性总偏差和乘客总等待时间为目标,建立多目标混合整数非线性规划模型。对模型中的非线性约束将其线性化,并采用拉格朗日松弛算法以松弛目标函数,从而降低问题规模,使得模型易于求解。基于京雄R1线与大兴机场地铁线的“一”字形贯通线路的基础数据,设计仿真测试案例,验证模型和算法的可靠性。研究结果表明:早高峰时段内,相比于独立运营,开行贯通列车不仅能够很大程度提高跨线直达率,同时还能减少运用列车数量;贯通列车的开行使得跨线乘客的直达占比69.86%,有效提升了乘客的出行效率;在可接受时间内能够得到有效的周期运行图,并保证乘客等待时间合理。通过对市域铁路与地铁贯通运营下运行图与车底周转一体化编制的研究,为我国发展“四网融合”提供周期运行图与车底运用方面的参考。
As urban agglomerations and metropolitan areas continue to develop,the through operation of suburban railways and subways is increasingly considered in future rail transit planning and construction.This not only provides passengers with the convenience of direct journeys but also reduces operational costs.To satisfy the cross-regional commuting demand,enhance direct travel options,and reduce the workload of rail operators by compiling a cyclic timetable,it is necessary to optimize the integrated cyclic train timetabling and rolling stock circulation for through operation of suburban railways and subways.In this paper,a multi-objective mixed-integer nonlinear programming model was developed to minimize total train travel time,total turnaround time,total deviation of equilibrium and total waiting time for passengers.The nonlinear constraints in the model were linearized,and a Lagrangian Relaxation algorithm was applied to simplify the objective function,thus reducing the problem size and improving solvability.Based on the fundamental data of the through line of Beijing Daxing Airport Line and Jingxiong R1 Line,simulation cases were designed to verify the reliability of the model and algorithm.The results indicate that during morning peak hours,the introduction of through trains,compared to separate operations,significantly increases the cross-line direct travel rate and reduces the number of required trains.Specifically,the proportion of direct cross-line passengers reaches 69.86%,enhancing travel efficiency.An effective cyclic timetable can be generated within an acceptable time frame,ensuring reasonable passenger waiting times.This research on integrated timetable and rolling stock circulation for suburban railway and subway through-operation can provide valuable insights for the“four-network integration”development in China,offering practical references in cyclic timetable and rolling stock utilization.
