Research on the Safety Evaluation Index of Urban Rail Transit Network Operation

The traditional safety evaluation of urban rail transit operation was limited to the station or line, not from the perspective of the whole network operation safety. Specific to the characteristics of the urban rail transit network operation in the new situation, based on complex network theory, the urban rail transit network model was established, and the formalized description of the network model was given. Based on above, from the passenger traffic, environment and other aspects, the safety evaluation index of urban rail transit network operation was established, which included hidden trouble indexes, accident indexes and safety economic index, aiming at to provide support for overall safety evaluation.
