Abstract
Subway infrastructure is a representative urban infrastructure for sustainable urban development as part of its policy to harmonize with economic growth. As the transportation infrastructure of large cities develops with high speed and intelligence, more attention will be paid to its safety. The main cause of death in subway fires is asphyxiation, due to the closed specificity of the underground space. Therefore, smoke exhaust facilities should be capable of minimizing the effects of smoke to ensure the safe evacuation of passengers in the event of fire. In this study, three kinds of fire locations are adopted to analyze the distribution of platform temperature, CO, and visibility in connection with the smoke exhaust system operation method. We evaluate the performance of the applicable smoke exhaust system from ASET-based untenable area analysis. Fatality evaluation by escape analysis according to the smoke exhaust system estimates the fatality based on the tenability performance evaluation. Moreover, the FED method was used to evaluate tenability performance. Therefore, the result of this study suggests a solution for sustainable subway Disaster response from the performance evaluation of the subway platform smoke exhaust system for safe evacuation of passengers, which is essential for subway construction or remodeling.

To improve livability, subways are spotlighted as an alternative to solve traffic problems and environmental pollution problems of big cities in terms of mass transportation, low pollution, and low energy transportation
Wu et al [15] applied the comprehensive model based on the Bayesian network (BN) and the Delphi method to raise the accuracy of the fire extinguishing process and results against fires in subways, and quantified the factors impacting consequences of fires, of causes of fires, and of preventive measures against fires to propose methods for emergency decision-making

Summary
Subways are spotlighted as an alternative to solve traffic problems and environmental pollution problems of big cities in terms of mass transportation, low pollution, and low energy transportation. In order to secure passenger safety in subway fires, various kinds of studies have been carried out to maintain the platform as a safe evacuation environment. The most important factor in the case of subway fires is to ensure the safety of evacuees as well as to create a safe evacuation environment in the event of a fire from the construction of an optimized design of the smoke control system and the associated disaster preparedness training [21,22].

It was set conservatively so that the fatality occurs when the accumulated FED sum exceeds 0.3 [63,64]
