A Decision Method for the Catchment Area of Subway Station Under the Difference of Connection Modes

: There is an interaction between subway station and the catchment area around the station, the catchment area of subway station on surrounding land is closely related to the connection modes. At present, subway passengers mainly reach subway stations by walking, cycling and bus, and the catchment area of the three connection modes is different. In order to clarify the catchment area of subway stations, it is necessary to study the catchment area of the three connection modes of subway stations. This study starts with a generalized connection cost for each connection mode, constructing the generalized connection cost models, especially considering the psychological changes of passengers with the increase of connecting distance. On this basis, we use Logit-SUE model to construct the probability density curve of the superior connection distance of different connection modes in different types and different area subway stations. Taking Beijing Metro Line 4 as the research case, through analyzing the probability density curve of each station of Line 4 we calculate the advantageous connection range of each subway station with different connection modes, and take the advantageous connection range as the catchment area for each type of connection mode.
