A Study on the Development of Fatality Accident Scenarios of Railway Workers for Risk Assessment

초록

The objective of this study is to develop fatality accident scenarios for railway workers and assess the risk for each scenario. In this research, we develop accident scenarios using the Quality Function Deployment (QFD) method to analyze systematically and evaluate quantitatively fatality accident scenarios for railway workers. This approach was inspired by the Quality Function Deployment (QFD) method, which is conventionally used in quality management and is used at the systematic accident scenario analysis (SASA) for the design of safer products. In this study, QFD provides a formal and systematic schema to devise accident scenarios while maintaining the objectivity. The accident scenarioanalysis method first identifies the hazardous events and explains the hazardous conditions that surround the accident and cause railway accidents. 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 to be performed systematically as well as objectively, this method is useful in building better accident prevention strategies. Therefore, this study could serve to reduce railway accidents and could be an effective tool for a hazard analysis. To manage a large amount of accumulating accident/incident data, this study develop the framework of a railway accident analysis program. The program is an application running on the web which links organizations throughput the county to a central database. The database stores all of the information on each hazardous event in a single record, which can be accessed rapidly by every organization involved in the safety event. Also, Main hazardous events and conditions for railway workers in South Korea's railway system have been represented.
