철도교통은 기술적, 사회적, 문화적 환경의 변화 및 고속철도의 확장과 철도 구조개혁 등으로 현장에서의 인적요인으로 인한 오류가 증가로 안전을 위협하는 요소가 날로 증가하는 추세로 안전신뢰성 확보는 절대적이다. 따라서 인적오류를 근절하기 위한 안전시스템의 적정성 및 신뢰도에 대한 분석과 해외 선진철도의 안전정책 및 안전시스템의 변화와 발전 추세를 분석하여 국내 철도안전의 방향을 제시하고자 한다.

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.
