In this paper, walking distance and diverting ratio from Shibuya station, Tokyo, where redevelopment around the station is planned, to all surrounding facilities are calculated using pedestrian path network in the neighbor of the station. We observe that walking distance is shorter in northern and western parts, whereas it is longer in southern and eastern parts, and that diverting ratio is high in circumference and southern part of the station where the influence of a pedestrian overpass to stride over Route 246. We also estimate that average walking distance decreases by 139 meters by the installation of the high-level pedestrian decks around the station, which is planned in a redevelopment plan in the neighbor of Shibuya station.
