How to use the advantages of the subway to a greater extent, make the subway and other modes of travel more effective, planning multi-mode combined travel connection facilities based on subway stations, is to integrate urban transportation resources, expand the radiation range of the new subway, and reduce the overall travel cost of the city Useful exploration. This paper combines the cutting-edge travel demand theory to study the planning of multi-mode combined travel connection facilities, which has certain theoretical value and practical significance. In this paper, a number of logistics models are constructed and the models are calibrated to obtain the connection sharing rate prediction method. Based on the relevant facility construction standards, the scale of the connection facilities is matched with the passenger flow data to obtain the scale demand forecast model of each connection facility and perform parameter calibration. Finally, take the Dongfang Square Station of Changchun Metro Line 2 as an example to make a specific analysis and give a planning scheme.
