Abstract: An urban rail transit transfer station is the junction of two or more lines. The amount of transfer station (network node) is gradually increasing in rail transit network operation. We address its transfer efficiency from the perspective of an operator, analyze the utility of transfer efficiency, and propose the concepts of effective and noneffective transfers. We further divide effective transfer into higheffective and loweffective transfers. We then employ AFC data mining technology to explain the application as an example. We eventually state the significance and features of transfer efficiency assessment.The research provides theoretical surport for improving the management of interchange station and realtime monitoring of pass engers.

Key words: urban rail transit, interchange station, interchange efficiency, utility analysis
