Abstract

Uncertainty is one of the most important concepts for safety assessment. In this paper, uncertainty is introduced into the safety assessment of railway system. After some discussions on the safety assessment framework of railway safety, we examine what categories of uncertainty are necessary. Then we introduce a case study on an externally initiated accident sequence to discuss the usefulness and difficulty of uncertainty for railway safety.
