Abstract：Reducing the traction energy is one of the efficient methods to cut down the energy com-sumption of subway systems.The traction energy is determined by the driving strategy of trains. This paper introduces the energy-efficient driving strategy research in Beijing Yizhuang line.The research starts with the investigation of the data about the infrastructure,operation,vehicle, power supply system,and the energy consumption such that the energy-efficiency background of the Yizhuang line is known.Considering the operation characteristic of subway,we present three key index to evaluate the energy consumption of Beij ing Yizhuang line.Taking the ant colony op-timization approach as the core algorithm,the research develops a simulation system for the train driving.The simulation system can optimize the target speed and the control strategy of the ATO system with the collected data.Finally,the night experiment is implemented with the optimized algorithm of ATO applied in the practical system.The results show that the energy consumption of a single train is reduced by 5 .6 7% with applying the proposed approach.
