The purpose of this study is to develop a methodology for producing a map of walkbicycle-access time to the stations of the Seoul Metropolitan Subway using GIS. Walking has its own peculiarities defined by access routes and time. They are to be affected by the obstacles such as crosswalk, underpass and pedestrian overpass. Walking could also be discontinued by other reasons. The methodology was developed in this research to calculate the access time using a shortest-path algorithm in consideration of the walking conditions. For its application, a pedestrian network was built for the Gangnam area of Seoul. On the basis of the network access routes and time were calculated using the methodology. And the so-called unfavorable areas in using subway were identified, where the access time to subway station exceeds 10 minutes. The methodology can also be applied to make a pedestrian accessibility index, which is to be compared with land prices, building uses, or sales.
