Whenever some new measure to promote safety is being considered, one major input into the decision making process is to be some formal assessment of the costs and benefits involved. What levels of safety do many stake holders believe the railway should deliver? This paper is a contribution to the efforts to answer the question. In this study, under Willing-To-Pay(WTP) based value of preventing a fatality(VPF) approach, we will study how much people are willing to trade off safety against other desirable things, summarize accepted quantitative criteria for safety quantitative criteria for safety decision, describe differences between these criteria and some current risk control actions, and present an outline of work under way to address issues related to cost-benefit analysis(CBA).

The objective of this study is to devise an accident scenario analysis method adept at creating accident scenarios at the Preliminary Hazard Analysis(PHA) step of a hazard analysis for railway system. This approach was inspired by the Quality Function Deployment(QFD) method, which is conventionally used in quality management and was used at the systematic accident scenario analysis(SASA) for the design of safer products. In this study, the QFD provides a formal and systematic schema to devise accident scenarios while maintaining objective. The accident scenario analysis method first identifies the hazard factors that cause railway accidents and explains the situation characteristics surrounding the accident. This method includes a feasibility test, a clustering process and a pattering process for a clearer understanding of the accident situation. Since this method enables an accident scenario analysis method to be performed systematically as well as objectively, this method is useful in building better accident prevention strategies. Therefore, this study can serve to reduce railway accident and be an effective tool for a hazard analysis.
