城市轨道交通安全风险监管与治理双闭环机制
Double Loop Mechanism for Safety Risk Supervision and Governance of Urban Rail Transit

为了研究建立城市轨道交通运营中的安全风险与隐患排查治理闭环体系，分析城市轨道交通行业的垄断特征表明其PDCA循环动力源主要来自政府监管、市场压力与乘客，构建了集运营单位安全管理PDCA环和运营主管部门安全监管PDCA环于一体的双重预防闭环机制模型。这一机制有助于全面识别、评估和控制安全风险，提升城市轨道交通的安全运营水平，确保乘客出行安全。
In order to study and establish a closed-loop system for identifying and managing safety risks and hidden dangers in urban rail transit operations, an analysis of the monopoly characteristics of the urban rail transit industry shows that its PDCA cycle is mainly driven by government regulation, market pressure, and passengers. A dual prevention closed-loop mechanism model was constructed, which integrates the PDCA cycle of safety management by operating units and the PDCA cycle of safety supervision by operating supervisory departments. This mechanism helps to comprehensively identify, assess, and control safety risks, improve the safe operation level of urban rail transit, and ensure passenger travel safety.
