Abstract

In order to effectively reduce the risk of subway fires and to improve the safety of passengers, a review of the background to subway fires employing literature and comparative analyses, computer simulation, expert consultation, and other research methods has been employed to conduct an in-depth study of subway fire risk assessment and control measures. A subway fire risk assessment model based on analysis theory was established. Firstly, a subway fire risk evaluation index system was developed, and the weight values of each level were determined using the interval analytic hierarchy process (IAHP), then the evaluation was derived using the fuzzy evaluation method, and the passenger distribution simulation was introduced to improve the objectivity of the evaluation. The results show that the fire evaluation of this subway system is safe. The results show that a subway fire risk assessment model may provide a scientific basis for establishing prevention and control measures, extinguishing methods, passenger safety evacuation schemes, and carrying out fire safety management activities during subway operations.

Highlights

In recent years, with the advancement of urbanization in China, the number of people living in cities is continuously increasing
Since subway stations and trains are densely populated public gathering places, once a fire starts and if there is no timely and effective control, it is bound to pose a serious threat to the safety of people’s lives and property and has a significant impact on the smooth operation of urban transport. erefore, fire is the key point of subway emergency rescue
Li [21] conducted a simulation study on passenger flow guidance and small group effect in the evacuation process of subway stations, and the results showed that passenger flow guidance and small group have significant effects on evacuation time, evacuation efficiency, bottleneck area, and detour distance

Summary

Introduction

With the advancement of urbanization in China, the number of people living in cities is continuously increasing. Become a major problem that people must face when traveling, especially in some large and medium-sized cities, where congestion is more serious. Subways bring convenience to people when traveling and have the characteristics of safety, punctuality, speediness, environmental protection, and large carrying capacity, as well as the advantages of saving land, reducing noise, saving energy, and reducing pollution. Gradually becoming an important tool for alleviating urban traffic congestion with its many advantages. Since subway stations and trains are densely populated public gathering places, once a fire starts and if there is no timely and effective control, it is bound to pose a serious threat to the safety of people’s lives and property and has a significant impact on the smooth operation of urban transport. In order to avoid or minimize the casualties and material losses caused by subway fires, and to ensure the subway operates in a safe environment, it is urgent to carry out the research on subway safety
