To improve the transfer efficiency of local network including rail transit and bus station, local transfer network was described based on space P and a reasonable network size was determined. Considering the capacity of the station and station spacing as the constraints, optimization model was established to minimize the travel cost and model algorithm was proposed based on community structure of complex network. The model is applied to local transfer network including some station of Changchun light rail No.3 and bus stations around it. The results show that the overall transfer efficiency of the local network can be increased by 16％, and total system costs can be decreased by 6.16％ considering the case of the time value.
