城市轨道交通运营突发事件分级模型研究

Research on the classification model of emergencies in urban rail transit operation

对城市轨道交通运营突发事件的准确分级是城市轨道交通运营应急管理的基础。为快速、准确、便捷地对城市轨道交通运营突发事件应急响应进行分级,文章采用层次分析法,综合考虑城市轨道交通运营突发事件的事件属性、线网脆弱性、应急处置水平3方面的因素,建立多级递阶层次评价指标体系确定城市轨道交通运营期间的突发事件等级。研究成果采用重庆市轨道交通2019年度全年运营时段突发事件数据进行验算,并与企业现行的划分标准进行对比,结果表明采用层次分析法对城市轨道交通运营突发事件进行分级,方法可行且结果更精准。成果可用于城市轨道交通线网运营实际的应急指挥工作中,精准化、动态化判定应急事件的分级,从而高效指导应急处置工作。

Accurate classification of emergencies in urban rail transit operation is the basis of emergency management in urban rail transit operation.To classify the responses against emergencies in urban rail transit operation in a swift,accurate,and convenient manner,this article adopts the analytic hierarchy process(AHP)and comprehensively considers the three factors of emergencies in urban rail transit operations,namely event attribute,network vulnerability,and emergency disposal level,and establishes a multi-level and hierarchical evaluation index system to determine the grade of the emergencies that occurred during urban rail transit operation.The research results are calculated using annual operating hour emergency data in 2019 of Chongqing rail transit,and are compared with the current classification standards of the enterprise.The results show that the AHP method is feasible,and the results are more accurate for the classification of emergencies in urban rail transit operation.The results can be used in actual emergency command works of urban rail transit network operation,accurately and dynamically classify the emergency events to efficiently guide emergency disposal work.
