Most railway accidents are due to human error. Therefore, safety of railway systems dependant upon reliable task performance of railway staff. In order to efficiently manage reliable task performance ability of railway staff, by conducting human reliability analysis(HRA), it is possible that identifying and assessing human failure events in the framework of the probabilistic risk assessment(PRA) of the systems. The purpose of this study is to manage human error failure events and to calculate the diagnosis human error probabilities and execution human error probabilities, by performing human reliability analysis applied RSSB-HRA methods for Signal Passed AT Danger(SPAD) In this paper, using the RSSB-HRA method, human reliability analysis for possible causes of SPAD events was performed. As a result of analysis, Human Error Identification(HEI) and Human Error Probability(HEP) for each causes of SPAD were derived

Railway accidents have caused tremendous casualties and loss of property. In order to reduce the rate of accidents, it is important for the railway operators to elevate their recognition and give effective training as a safety education and training. Through the previous study, we developed regulatory guidance for developing safety education and training program. Then, three educational technology specialists verified it primarily. In this paper, we investigated present condition for running education and training system of domestic railway through result of In-depth interview. And we verified actual reflection through result of Checklist. Finally, improved regulatory guidance for developing safety education and training program was suggested in this study.
