Risk Assessment Based on Accident Theory in Urban Railway Transportation

The paper analyses accident type of urban railway transportation, including fire, trains accident, platform train interface, station area accidents, explosion, power failure, structural failures, according to the statistic data, the risk assessment model based on accident theory is established. Our understanding of safety risk should not be based just on perception, but on past evidence and data, and the best information on potential future risk that can be derived from them. The Total Risk Assessment Model is a vital tool in providing this risk insight. It provides a structured representation of the causes and consequences of potential accidents arising from operations and maintenance on the mainline railway. The models could lead directly to injury or fatality to passengers, workers or members of the public. These events include hazardous event train accidents, movement accidents and non-movement accidents. The risk results are presented as a measure of the absolute risk and should only be used as an input to, and not as a substitute for, decision-making. The emerging thinking on safety decision-making within the railway industry has recognised the need to consider the distribution of risk in terms of fatalities, major and minor injuries, as well as equivalent fatalities.
