The rapid development of social, economic and scientific technology has created favorable conditions for the improvement of the technical level of urban rail transit. The improvement of the technical level of urban rail transit has also made it more convenient for urban residents to travel and provided better services for residents. The application of driverless technology aims to explore reasonable solutions to reduce maintenance costs and improve operation efficiency. Based on the scene of full-automatic operation of urban rail transit, this paper explores the car washing scheme of full-automatic running trains and puts forward the solution, which provides a reference for the design of signal system and car washing system.展开更多
