Abstract:

It is of great significance to study the spatial form of the catchment area of metro stations and their influencing factors for establishing a long-term interaction mechanism between rail transit and the built environment and guiding the development of land use around metro stations based on the TOD development model. In order to more accurately express the form characteristics of the catchment area of the stations, this paper takes Xiamen as an example, obtains the spatial distribution of the actual passenger flow source of each station of the metro through the Amap commuting OD data and the Amap route planning data, and uses the Standard Deviation Ellipse (SDE) method to establish the oblateness, relative distance, angle, and offset along the line to describe the form of the catchment area of each station. Based on the index system, the spatial form types of the catchment area of metro stations are summarized, and the influence mechanism of each station and the surrounding built environment, and station attributes under various form categories are revealed. The results show that: ① There are obvious differences in the eccentricity and aggregation direction of the catchment area of the metro stations inside and outside the island in Xiamen. The catchment area direction of most stations tends to be vertical to the line, and the source center tends to shift to the vertical direction of the line; ② According to the importance of the four indicators to measure the homogenization of the service scope of the station, the stations are divided into three categories: coupling service, eccentric service, and complete centrifugal service, and further divided into eight spatial forms. Among them, the coupling service stations are closest to the homogenization mode of theoretical TOD; ③ There is a certain aggregation phenomenon in the spatial distribution of various stations. The coupling service stations are mainly distributed in the west and south of the island. The eccentric service stations are mainly distributed in the north of the island and outside the island. The completely centrifugal stations are mainly distributed outside the island and in the east of the island; ④ The scale and location of factors such as land use layout and development degree, station density and layout, and location environment will make the station form different catchment area forms. The results are of great significance for supplementing the research methods of the catchment area of metro stations and improving the comprehensive benefits of rail transit.
