Summary of PMC indices for URTOEPs.

Emergency response plans play a crucial role in mitigating safety risks associated with urban rail transport operations and effectively responding to emergencies in underground spaces. This study evaluates and analyzes the emergency response plans for rail transit operations in 33 cities in China, focusing on the consistency and completeness of the plans. The evaluation index system for Urban Rail Transit Operation Emergency Plans (URTOEPs) consists of 9 primary variables and 42 secondary variables, constructed based on the text analysis and the Policy Model Consistency (PMC) index model. It fills the gap of more fragmented analysis and less holistic quantitative assessment in the research of established urban rail transit emergency plans. The results indicate that URTOEPs are well-designed, but there is still room for improvement. The mean PMC index value for 33 URTOEPs is 7.83, which reflects a good grade overall. Of these, 11 URTOEPs achieved an excellent grade while 22 were rated as good. Meanwhile, based on the mean PMC index of first-level variables and the PMC-surface diagrams of six representative plans, the emergency plans need significant improvement in restoration and reconstruction, plan application, and preventive preparedness. This study enriches the research related to text quality assessment of emergency plans, identifies structural deficiencies in the plan system through quantitative assessment, and provides empirical references for the optimization of urban rail transit emergency plans and the formulation of policies related to urban risk management.应急方案对于降低城市轨道交通运营相关的安全风险、高效应对地下空间突发事件至关重要。本研究针对中国33座城市的轨道交通运营应急方案开展评估与分析，重点考察方案的一致性与完备性。本研究基于文本分析与政策模型一致性（Policy Model Consistency, PMC）指数模型，构建了城市轨道交通运营应急方案（Urban Rail Transit Operation Emergency Plans, URTOEPs）评估指标体系，该体系包含9项一级变量与42项二级变量，填补了当前城市轨道交通应急方案研究中分析较为碎片化、整体定量评估不足的空白。研究结果显示，当前城市轨道交通运营应急方案设计整体良好，但仍存在优化空间。33份应急方案的PMC指数均值为7.83，整体评级为良好；其中11份方案获评优秀，22份评级为良好。同时，通过一级变量PMC指数均值与6份代表性方案的PMC曲面图分析可知，当前应急方案在恢复重建、方案应用与预防性准备环节仍存在显著优化空间。本研究丰富了应急方案文本质量评估相关研究，通过定量评估识别了方案体系的结构性缺陷，可为城市轨道交通应急方案优化及城市风险管理相关政策制定提供实证参考。
