A paper which analyses accidents involving train-person collisions on the national railway of South Korea. These accidents account for more than 40% of railway accidents in South Korea and 80% of injuries. Research into train-person collisions uses accident scenarios developed using the quality function deployment (QFD) method to analyse systemeatically and evaluate quantitatively fatality accident scenarios for passengers, railway staff and members of the public. In this study, the QFD method provides a formal and systematic schema to devise accident scenarios while maintaining the objective.
