철도건널목 사고 위험분석 및 위험도 평가모델 개발

초록

The purpose of this study was to develop the hazard analysis and risk evaluation model for railway level-crossing accident. In this paper, hazard factors and hazard events on L/C accidents were identified by a review of accident history and engineering interpretation of accident behavior. The probability evaluation model which was based on accident progress scenario was developed through the ETA technique, and a standard code management system of causal factors was proposed for hazard events. Also severity assesment model was composed of effect factors on safety barrier and criteria of casualties estimation. Finally, validity of risk assesment model for L/C accident was reviewed by comparison with actual accident results.
