Basic Requirements for the Application of Risk Concept on Railway Safety Improvements

철도안전관리에 위험도개념 적용을 위한 기반 요건에 대한 연구

In railway system, the first step of safety managements is the identification of current safety level. Among many safety indexes, risk concept is the prevailing and most effective one in many developed countries for the safety management. But many requirements such as, accident classification rule, risk levels or broadly acceptable regions, safety cost benefit analysis, VPF, equivalent fatality and failure database are needed for the application of risk concept in railway. Basic requirements for the application of risk concept on railway safety improvements are derived in this study.
