摘　　要：列车运行图与客流需求息息相关,当运行图提供的能力与客流需求相匹配时,城市轨道交通系统既可以充分地适应乘客的需要,还可以最大限度地利用自身的运输能力。通过对乘客出行路径选择影响要素的探讨分析,改进有效路径搜索算法,构建客流分配模型并利用MSA算法对模型进行求解。基于配流结果提出列车运行图能力与客流需求匹配程度的定量评价方法,利用多目标合成的方法进行计算。基于能力匹配度的计算结果,采取相应的分时段、分区段、分方向的优化方法,实现列车运行图能力与客流需求的协调匹配。最后以南京轨道交通为例进行实例计算,与能力匹配度进行对比,结果表明:本文采取的优化方法能够使城市轨道交通列车运行图与客流需求匹配度提高19.59%。The synchronization between rail transit train diagrams and passenger demand is crucial for urban transit efficiency.When the operational capacity aligns with the passenger demand,the system can effectively meet passenger needs while maximizing transportation efficiency.This paper explored factors influencing passenger route selection,constructed a passenger flow allocation model,and solved it using the MSA algorithm.A quantitative evaluation method was proposed to assess the degree of alignment between rail transit train diagrams and passenger demand,employing a multi-objective synthesis approach for computation.Based on the calculated degree of alignment,optimization strategies were implemented across different time periods,sections,and directions to achieve coordination between rail transit train diagrams and passenger flow demand.Using Nanjing’s rail transit system as a case study,the results indicate a 19.59%improvement in matching between rail transit train diagrams and passenger demand,compared with the degree of capacity matching.
