摘要
地铁郊区线路是城市通勤的重要方式,在早高峰期间可将郊区通勤乘客快速运送至中心城区的工作地点.由于通勤客流的巨大需求以及目的地集中性,即早高峰期间大多由郊区各站流向中心城区若干站点,导致列车和车站站台的过度拥挤,尤其是靠近市中心的地铁车站.据此,本文构建了列车运营计划与客流控制协同优化模型,列车运营计划包括大小交路和非等间隔时刻表服务.优化目标为降低最大站台滞留人数、站外总限流人数以及列车的总走行公里.为保证方案的可行性,模型考虑了列车车底的衔接以及最大可用车底数限制.针对所提出的大规模非线性模型,设计了嵌套暴力搜索的遗传算法进行求解.北京地铁房山线案例表明,本文提出的站外限流和小交路计划可有效降低靠近市中心的地铁车站的滞留乘客数,缓解高峰期拥挤现象.与现实无限流方案和本文无小交路方法相比,本文综合优化方法可提升目标函数的优化率超过14.8％.
Abstract
Suburban metro lines play an important role in daily commuting, which transport passengers from suburban areas to the city center in the morning peak. However, the excessive commuting demand leads to oversaturation on trains and platforms, especially at the stations near the city center. To ease the oversaturation of suburban metro lines, an integrated optimization on inbound passenger control and train service planning including short-turn and non-periodic services has been proposed. The proposed approach aims to reduce the maximum number of stranded passengers at the platforms while the total number of waiting passengers outside stations and the running kilometers of all train services are also minimized. To ensure the feasibility of solutions, the train connections and available rolling stock fleet size have been formulated. A genetic algorithm embedded with brute force is adopted to efficiently solve the proposed large-scale nonlinear model. Finally, a real case of Beijing subway Fangshan line shows that the inbound passenger control and short-turn services help to evidently reduce the stranded passengers at the stations near the city center. Compared with the practical train services without inbound passenger control and the integrated model without short-turn services, the integrated model is able to improve the sum of three objectives by more than 14.8％.
