철도건널목 사고 위험도 평가를 위한 사고진전 시나리오 개발

초록

In this paper, initial hazard events which determine a probability for level crossing accident were defined from the analysis of accident history data as a form of FTA. The type of initial event were classified by stagnant type and violative type. And the accident proceeding scenario of initial events which estimate the severity of accidents was proposed as a form of ETA. Resulting risk assessment model of level crossing accident will be produced by a probability and severity of initial event.
