A Railway Transportation Safety Assessment Method Based on Safe State Index

摘要

In order to make a better railway transportation safety system and reduce the number of railway accidents, we establish a safety status index to assess the railway transportation safety level. We calculate the risk value by classifying the safety information provided by the China Railway in accordance with the risk factors of consequence. The combinations of risk value and the level of index weight are used to grasp the overall situation of safety management at all levels. The final result is represented in the form of a safety level which can be used to guide the decisions making during the safety warning.
