JAUE2020-058: Research on migratory activity of pedestrians using betweenness centrality-A case study around Hakata station and Tenjin

Abstract

In this study, the streets around Hakata Station and Tenjin station in Fukuoka city are evaluated by using betweenness centrality. Betweenness centrality is a type of centrality that is a network index, and represents the ease with which a point in a network can be selected as the shortest path. This study is about the correlation between the pedestrian amount and the betweenness centrality, comparison of the betweenness centrality around Hakata Station and around Tenjin station, and qualitative analysis of those betweenness centrality. The purpose of this is to clarify the street characteristics around Hakata Station and around Tenjin station. As a result of simple regression analysis using the betweenness centrality and pedestrian amount around Hakata Station and around Tenjin station, the coefficient of determination is low in both areas and no clear correlation is observed. However, comparing the centrality of Hakata station and Tenjin station, it is confirmed that the centrality of Tenjin station, which is the terminal station, has a smaller variance value. Furthermore, it has been confirmed by qualitative analysis that some street shapes affect the betweenness, and it is expected to contribute to future street plans and facility layout plans.
