The invention provides an urban rail transit accident cause identification method and system and electronic equipment, and belongs to the field of rail transit management.The method comprises the steps that a suspected cause set of a to-be-identified traffic accident is acquired; based on the suspected cause set of the traffic accident to be identified and an HFACS model, establishing an accident cause classification model; calculating the influence degree between secondary causes in the accident cause classification model by adopting a decision test and evaluation test method to obtain a comprehensive influence matrix; according to the comprehensive influence matrix, performing hierarchical division on each secondary cause by adopting an interpretation structure model method to obtain a multi-level hierarchical network structure model; based on the accident cause classification model and the multi-level hierarchical network structure model, calculating the comprehensive weight of each secondary cause by adopting a network analysis method; and sorting the comprehensive weight of each secondary cause to determine the main cause of the traffic accident to be identified. According to the invention, the main cause of the traffic accident can be accurately identified, and the safety of rail transit operation is improved.
本发明提供了一种城市轨道交通事故致因识别方法、系统及电子设备,属于轨道交通管理领域,方法包括:获取待识别交通事故的疑似致因集合;基于待识别交通事故的疑似致因集合及HFACS模型,建立事故致因分类模型;采用决策试验和评价试验法计算事故致因分类模型中各二级致因间的影响程度,得到综合影响矩阵;根据综合影响矩阵,采用解释结构模型法对各二级致因进行层级划分,得到多层次递阶网络结构模型;基于事故致因分类模型及多层次递阶网络结构模型,采用网络分析法计算各二级致因的综合权重;对各二级致因的综合权重排序,以确定待识别交通事故的主要致因。本发明能够准确识别出交通事故的主要致因,提高了轨道交通运行的安全性。
