Estimating the Walking Distances of Subway Users in Catchment Area according to Characteristics of Land Use

Subway areas must be developed by analyzing the characteristics of land use in their catchment area and reflecting them in order to efficiently use some limited land. Focusing on the reality, understanding the characteristics of land use in subway area in advance is important because they greatly influence human activities and travel patterns. Therefore, this study aims at verifying the differences in the range of catchment area by estimating the walking distances of subway users in subway areas having each characteristic of land use. The results of the study are as follows, the walking distances in residence-centered stations are different from them in non residence-centered stations. Catchment areas are estimated by cumulative distribution curve with the rate of subway users by distance. The results show that 60% of users are willing to walk up to 260m in Gangnam station, 270m in Isu station, 370m in Gireum station, and 370m in Hwagok station while 90% of them 410m, 450m, 600m, and 570m respectively. As a result, catchment area is up to 550~650m on average from station area which has residential characteristic, and 400~500m from station area having non-residential characteristic. This shows that catchment area is different according to its land use characteristic. This study differs from other studies that it proves the difference in catchment area according to the types of land use.
