摘要

随着城市轨道交通的发展，地铁成为市民公共交通出行的首选对象。为提升乘客出行体验，实现运力与运输需求的匹配，同时降低城轨站台候车区拥挤度，文章基于运行图的均衡性指标对站台客流密度的优化进行了研究。首先利用排队论基础方法和理论，建立了以城轨站台候车区客流密度为研究对象的计算模型，分析出列车运行图均衡性与站台候车区客流密度的关系。然后，通过创建峰期、创建过渡期、连接任务线、冲突处理、均衡处理等过程，实现了城轨均衡运行图的自动编制。最后结合长沙轨道交通4号线客流数据，通过仿真验证了方法的有效性。仿真结果表明基于该方法的自动编制的运行图比人工编制的运行图其站台候车区最大客流密度更低，因此算法具有更好的实用价值。

Abstract

With the development of urban rail transit

metro has become the preferred mode of public transportation for citizens. In order to improve passengers' travel experience

realize the matching of transport capacity and transport demands

and reduce the congestion in waiting areas of urban rail transit platform

in this paper

the optimization of the passenger flow density on platform was researched based on the balance indexes of running chart. Firstly

based on the basic methods and theories of queuing theory

a computation model which takes the passenger flow density in waiting areas of urban rail transit platform as the research subject has been established

and the relationship between the balance of running chart and the passenger flow density in waiting areas on platform has been analyzed. Then

through the process of creating peak periods

creating transitional periods

connecting task lines

conflict resolution

and balance treatment

the automatic generation of the balanced running chart of urban rail transit has been realized. Finally

combined with passenger flow data of Changsha metro line 4

the effectiveness of the method has been verified by simulation. The simulation results show that the automatically compiled running chart based on this method has a lower maximum passenger flow density in waiting areas on platform in respect of the manually compiled running chart. Therefore

the algorithm has a better practical value.
