통행 특성별 OD 자료와 Community Detection 기법을 활용한 공간위계별 생활권 설정 연구: 2010년 수도권 가구통행실태조사 자료를 중심으로

Abstract

This study aims to designate the boundary of living zones by its spatial hierarchy, using the 2010 household travel survey data and the community detection technique. Community detection technique, one of the social network analysis methods, is a useful tool to analyze interconnected relationships between network nodes. Applying this technique, we propose a scientific method to determine the boundaries of living zones using the origin-destination trip matrices by travel characteristics. In our research, we consider the travel purpose, travel time and trip modes as travel characteristics. The results of our study indicate that we can identify the living zones of metropolitan area from daily living zones to regional living zones through the community detection technique. Furthermore, we also identify that the spatial boundaries of living zones does not exactly match with the existing administrative borders, when taking account of the actual movements of people’s activities. This study contributes to the development of spatial planning boundaries in urban and regional planning, providing the designation method of the living zones by spatial hierarchy in the metropolitan area.
