Transfer Efficiency Evaluation Method of Urban Rail Transit based on the Generalized Cost Function

This paper gives out a method to evaluate transfer efficiency of urban rail transit using a new built mathematical model for transfer streamlines and the generalized cost function. We take Sihuidong Station, one important transfer station in Beijing urban rail transit network, as an example. As for this example, we at first give out basic information of Sihuidong Station including its platform layout, transfer mode and transfer paths. Then the transfer efficiency is evaluated by using the generalized cost function, where we take consideration of some main influence factors such as walking time, transfer waiting time. We also analyze the effects of different crowding levels in peak and off-peak periods.
