In the event of an outbreak of fire in an underground subway station, the speed of movement slows down as many people try to evacuate at once and bottlenecks might begin to occur in some locations, potentially resulting in catastrophic accidents. This study aims to analyze egress routes depending on, among other factors that influence evacuation in the event of an outbreak of fire, the characteristics of occupants and the initial points of fire using the GongEgress simulation program. The simulation result shows that the evacuation time of the vulnerable users is found to take 18% longer than that of ordinary people, and the transfer passageways have lower survival probability compared to that of the platforms. Through the analysis of the results, the structural features of the underground subway station and the points of fire are proved to be the major factors that determine the survival probability of the occupants. Therefore, safety training for passengers through conducting fire drills at the station or fire accident simulations can be established in the evacuation route and plan for reaction at the station or fire accident simulations.
