随着我国城市轨道交通快速发展,运营规模不断扩大,客流量与日剧增,对城市轨道交通安全保障等提出了更高的要求。本文总结阐述城市轨道交通运营系统安全风险特性,提出了系统识别城市轨道交通运营安全风险的相关定性、定量方法与技术流程,并基于运营调度日志数据运用Apriori关联规则算法实现了关键运营安全风险因素的定量化识别与分析。

英文摘要：

Nowadays,The aim of the ＂Type of Proactive Accident Prevention＂ in modern safety risk management poses greater challenges for the urban rail transit safety system. The issue of the research in this paper is to identify and analyze the risk sources and risk elements in the process of the operation organization for the benefit of building up the Apriori model for analyzing the inter dependent relations of the various risk factors from the perspective of mass transit operation management.
