The passenger traffic of rail transit has increased year by year, and the passenger traffic of the ground bus has been declining year by year. The coordination and connection between the subway station and the bus station have been strengthened, and the transfer efficiency of the subway station has been improved. This paper analyzes the transfer efficiency of Beijing subway stations. Firstly, based on the infrastructure, operational characteristics and passenger flow characteristics, the index system is built. Then, based on the grey relational degree theory, the transfer efficiency evaluation index model is established, and the cause analysis is carried out. Finally, Taking the Beijing subway station as an example, the cause analysis is carried out from two aspects: the indicator system and the spatial distribution characteristics of the station. This paper scientifically evaluates the transfer efficiency between urban rail transit and ground bus, and provides a theoretical basis for improving the connection between subway stations and bus stops.
