Several studies using graph theory have been conducted to analyze railway networks. However, train types such as express and rapid are not considered in the construction of the spatial network, and it is difficult to analyze the complex railway network in which various train types operate. In this study, we constructed a railway network model considering train types in the Tokyo metropolitan area, and proposed 11 indicators for station accessibility evaluation from OD data in the 2018 Tokyo metropolitan area person trip survey and timetables of each line. Stations were classified into five clusters by principal component analysis and cluster analysis. These classifications made it possible to visualize the accessibility and compactness of each station and to grasp the urban structure from the railway network.
