서울시 POI 빅데이터를 활용한 도시활력과 영향요인 분석

초록

According to an urban theorist, Jane Jacobs, urban vitality only promotes regional economic development but also improves street safety and enhances the sense of community through human contact. In this context, the purpose of this study is to analyze the relationship between various neighboring environments influencing urban vitality based on Jane Jacobs’ theory using global positioning system-based de facto population data and point-of-interest (POI) big data. Based on the dependent variables from the de facto population data to represent urban vitality, the relationships between urban vitality and surrounding physical environments were analyzed using the POI data. In addition, the interaction effect of independent variables on urban vitality was analyzed. The results show that urban vitality is highly associated with POI-based land-use variables and other physical environmental factors. In addition, the factors affecting urban vitality are different from the commercial and residential areas. In particular, the level of de facto population in the residential area is more likely to be associated with neighborhood service facilities, such as education, transportation, sports, and leisure. Next, the building coverage ratio is negatively associated with the number of the de facto population regardless of land use zones. This finding indicates that various neighborhood open spaces are crucial in urban vitality. In addition, the density of the total floor area of a building has a positive impact on the de facto population but is only significant in the commercial area. Finally, this study recommends policy implications to promote urban vitality in residential and commercial zones.
