In order to increase the utilization efficiency of urban rail transit data, improve the comprehensive efficiency of equipments and Adapt to the high safety development requirements of urban rail transit, an evaluation model of comprehensive efficiency of urban rail transit equipments based on super-efficient Data Envelopment Analysis(DEA) and Tobit model was established. Firstly, the factors affecting the equipment efficiency were Analyzed from the aspects of input resources and output capability, and the efficiency evaluation indexes and calculation formulas of equipments were determined. Secondly, combined with the super-efficient DEA and Tobit model, the comprehensive efficiency evaluation method of urban rail transit equipment and its influencing factors analysis method were proposed. Finally, the vehicle system equipments of a line in Shenzhen Metro was selected as the evaluation case, it was concluded that the comprehensive efficiency of vehicle moving device equipment was the best, and the comprehensive efficiency of on-board Automatic Train Protection(ATP) system equipment was the worst. The key factors affecting the comprehensive efficiency of equipment were the equipment maintenance cost investment rate and the equipment maintenance personnel investment rate, which was consistent with the actual situation. The result shows that the method can evaluate the comprehensive efficiency of different urban rail transit equipments and find out the key factors affecting the equipment efficiency, which can provide reference for equipment evaluation of urban rail transit operation unit.
