Development of accident scenarios for the risk assessment in railway system: focused on the train collision

초록

The risk assessment is increasingly emphasized for the prevention of accidents in recent years. The objective of this study is to develop accident scenario models for the quantitative risk assessment of railway accidents likewise train collision. To develop these scenarios, hazardous events and hazardous factors were identified with analyzing various accident information and legal requirements. Each accident scenarios consists of an occurrence scenario and a progress scenario. The occurrence scenario refers to the occurrence process of the event before the hazardous event. The progress scenario means the progress process of the event after the hazardous event.
