城市轨道交通网络末班车衔接优化模型

Optimum Model of Last Train Connection for Urban Mass Transit Network

城市轨道交通网络运营结束阶段,末班车在路网换乘站内能否实现合理地衔接,最能体现出以人为本的客运服务以及科学高效的运营秩序。根据城市轨道交通网络特点,提出了城市轨道交通网络末班车衔接编制的原则。从站间列车运行时间约束、线间列车换乘衔接、末班列车线间衔接目标等角度,研究了轨道交通网络末班车衔接优化量化方法,建立了网络末班列车衔接优化模型。以北京轨道交通城区1号线、2号线和5号线局部路网为实例,编制了网络末班列车的优化时刻表。算例结果表明,模型及其优化算法可行,对路网运输计划编制工作有较强的实用性。

At the end of everyday rail transit operation,the rational connection of last trains at interchange stations on rail transit network can reflect directly the people-oriented service level,and the efficient operation order. Firstly,based on the complexity of urban rail transit network,the principles in last train connection system are proposed. Secondly, from angles of inter-station running time constraint,interchange connection and objectives of last train linkage on different lines,the optimum quantitative method for last train linkage is studied, and an optimization model is set up. Taking parts of Beijing rail transit Line 1, Line 2 and Line 5 as the research targets, an optimized timetable for last trains in network is produced. The algorithm result shows that the model and optimization algorithm is feasible and practical for the network transport planning.
