With the vigorous development of the current e-commerce industry, China’s urban logistics business volume has achieved rapid growth and has gradually become the country with the largest express delivery industry. However, the parcel distribution problem caused by the surge in express logistics has gradually become one of the main bottlenecks restricting the sustainable development of urban transportation logistics. The metro has the characteristics of strong timeliness, low pollution, and large transportation volume. If the accessibility and excess transportation capacity of the existing metro network can be fully utilized, cooperating transportation of passengers and freight in express logistics is an important direction for the future development of urban logistics. Based on the existing stations, this paper proposes a freight transportation scheme of metro stations with a high degree of automation, and builds a simulation model to analyze freight efficiency and passenger- freight interference under the automatic scheme. The results show that the design scheme has little influence on passenger travel behavior in the station, and can promote the level of freight transportation service.
