In the current urban rail transit, the minimum inter-vehicle interval of a signal system is 2 minutes, and the traffic volume cannot meet the traffic volume even if the inter-vehicle interval of 2 minutes is adopted due to the fact that the traffic volume of the early peak and the late peak is large. To further increase the passenger capacity of a subway train, large marshalling subway trains, such as 6, 8, 10 marshalling trains, are typically used to increase the total passenger capacity by increasing the passenger capacity per train. However, as the passenger flow is small in non-early and late peak hours, if a large marshalling train is continuously adopted, the train basically has no load, and the energy consumption is increased; and the adoption of a large marshalling train and the increase of the running interval can cause that passengers need to wait for a long time to get on the train, thereby causing the reduction of service quality. On the other hand, the number of passenger flows of stations passing through the subway line is different, the passenger flow of the stations in the urban area is larger, and the passenger flow of the suburban area is smaller.
