轨道交通客流特性分析及安全风险评估研究综述

Review on Characteristics Analysis and Risk Assessment of Urban Rail Transit

整理分析前人在城市轨道交通客流特性分析、安全风险评估方面研究的侧重,从现有需求出发归纳出了有待研究的要点.已有研究更多地从宏观层面研究客流的运行状态,有待从微观角度深入挖掘乘客行为规律,剖析大客流演化机理、客流冲突致因机理.此外,当前对于轨道交通运营风险评估研究较多,从客流群体角度出发研究客流风险、疏散风险的研究相对较少.如何实现客流风险的动态分析、准确辨识与主动防御是目前亟待完善的内容,对于保障轨道交通系统运行安全具有重要意义.

This paper sorted out the previous studies on characteristics analysis of passenger flow and risk assessment of urban rail transit.The existing studies were reviewed and analyzed and the key points to be studied from the existing needs were summarized.It was found that more studies have been done on the operation of passenger flow from the macro group level.In the later stage,it was necessary to examine the passenger behavior regular pattern from the micro individual level,which was conducive to further analyze the evolution mechanism of large passenger flow and the cause mechanism of passenger flow conflict.At the same time,the research focused on the risk assessment of urban rail transit operation.There are relatively few studies on passenger flow risk assessment of urban rail transit.How to realize the dynamic analysis,accurate identification and active prevention of passenger flow risk is the area that needs to be improved urgently,which is of great significance to ensure the safety of rail transit system operation.
