摘要
[目的]针对目前城市轨道交通(以下简称“城轨”)线网客流分配计算过程重复性工作较多的问题,基于对城轨线网客流分配过程的研究,开发了城轨线网客流分配自动化计算程序。[方法]梳理了城轨线网客流分配自动化计算程序的开发需求。介绍了基于VISUM软件的城轨线网客流分配自动化计算程序的主要技术流程。基于需求分析,将该程序划分为线网供给方案建模、线网需求方案建模、交通分配计算及数据输出等4个主要功能模块。阐述了该程序中4个模块的操作内容以及参数传递过程。重点介绍了线网供给方案建模模块的计算过程与实现方法。[结果及结论]经实例验证,采用该程序进行城轨线网客流分配的计算,不仅可以满足客流分配所需的复杂的分析计算要求,亦能提高客流分配工作的效率。
[Objective]In view of the much repetitive work in the calculation process of passenger flow assignment in urban rail transit network,an automatic calculation program is developed on the basis of the research on the passenger flow assignment process.[Method]Requirements of developing automatic calculation program for passenger flow assignment in urban rail transit network are reviewed.The main technical process of the program based on VISUM software is introduced.Based on demand analysis,the program is divided into four main functional modules,i.e.network supply scheme modeling,network demand scheme modeling,traffic assignment calculation and data output.The operating content of the four modules in the program and the parameter passing process are described.The calculation process and realization method of the network supply scheme modeling module are emphasized.[Result&Conclusion]Examples verify that the program can not only meet the complicated analysis and calculation requirements of passenger flow assignment,but also improve its efficiency.
