The safety risk assessment system for urban rail transit operations has been studied to provide support and guidance for rail transit operations.Firstly, a risk assessment index system for rail transit operations is established from four levels: station train operation, station passenger capacity, station environment, and station equipment services, providing support for the safe and reliable operation assessment of rail transit.Then, a risk assessment model for rail transit operation safety is proposed, and an improved AHP method is used to determine the weight of the indicators.Then, evaluation scores of indicators at all levels are obtained based on the cloud model assessment method, in order to evaluate the risk level of rail transit operation, providing a judgment basis for rail transit safety operation.
