Since the introduction of PSD in 2005, the number of accidents involving passengers falling onto the tracks accidentally or intentionally have drastically decreased, but the number of PSD related passenger accidents is increasing. While existing papers on PSD have been devoted to systemic introduction and system improvement, papers on passenger casuality accidents due to deteriorated PSD have been limited. This paper proposes revising of the scenario model for passenger accidents using classified hazard sources of PSD.

도시철도는 1974년 1호선 개통이후 그 이용이 꾸준히 증가하는 추세이다. 이에 따라 도시철도 역사내에서 이용객의 안전사고의 위험이 높아졌다. 이러한 철도안전사상사고를 줄이기 위하여 철도운영시스템이 대부분 자동화되어 있다. 그럼에도 불구하고 여전히 철도안전사상사고의 사고의 가능성은 존재하고 있다. 본 논문에서는 서울메트로의 내부자료를 활용하여 철도안전사상사고의 유형, 연령별사고, 성별사고, 보행자 시설물별사고, 이용객별 사고, 그리고 철도안전사상사고의 사고원인을 분석하였다. 이를 기반으로 철도안전사상사고를 예방할 수 있는 대안으로서 철도안전교육프로그램 구축과 철도안전체험센터 구축방안을 제시하였다.

This study shows risk-based evaluation results of casualty accidents for passengers, railway staffs and MOP(Member of public) on the national railway in South Korea. To evaluate risk of these accidents, the hazardous events and the hazardous factors were identified by the review of the accident history and engineering interpretation of the accident behavior. A probability evaluation model for each hazardous event which was based on the accident appearance scenario was developed by using the Fault Tree Analysis (FTA) technique. The probability for each hazardous event was evaluated from the historical data and structured expert judgment. In addition, the severity assessment model utilized by the Event Tree Analysis (ETA) technique was composed of the accident progress scenarios. And the severity for the hazardous events was estimated using fatalities and weighted injuries. The risk assessment model developed can be effectively utilized in defining the risk reduction measures in connection with the option analysis.

Generally a road vehicle's wrong entry into level crossing gives rise to hazardous events, the eventual collision with a approaching train depends on the effective operation of safety barriers such a abnormal condition detecting or emergency braking. In this paper, the risk assessment models developed for the level-crossing accidents will be introduced. The definition of hazardous events and the related hazardous factors are identified by the review of the accident history and engineering interpretation of the accident behavior. A probability of the hazardous events will be evaluated by the FTA, which is based on the accident scenario. For the severity estimation, the critical factors which can effect on the consequence will be reviewed during the ETA. Finally, the number of casualty for the public(vehicle drivers) and the train passengers are converted into an equivalent fatality.
