Abstract
본 연구의 목적은 서울시를 대상으로 평일, 주말, 일주일(전체) 생활인구 자료를 활용하여 도시활력에 영향을 미치는 물리적 환경요인을 주거지역과 상업지역으로 나누어분석하고 도시활력 증진을 위한 정책적 시사점을 제시하고자 한다. 우선, Jacobs(1961)가 제시한 도시활력의 개념에 기반하여 도시활력을 해당 도시공간에서 사람들이 집중하는 정도로 정의하였으며, 이에 따라 2018년 집계구 단위의 낮 시간대의 생활인구 자료를 활용하여 도시활력을 측정하였다. 또한, 해당 건축물의 시설이용을 미시적으로 측정하기 위해 카카오 지도(Kakao Map) 웹에서 API를 이용하여 POI 자료를 수집하여 활용하였다. 나아가주거지역과 상업지역을 구분하여 도시활력에 영향을 미치는 물리적 환경 요인의 차이를 확인하고자 하였다. 나아가 본 연구는 도시활력을 측정하고 모니터링하기 위한 POI 자료의 활용방안뿐만아니라 서울시 주거지역과 상업지역의 도시활력 영향요인을 도출하고 도시활력 증진을 위한 정책적 시사점을 제시하고자 하였다.;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.
