압축도시 특성이 지역별 교통에너지 소비에 미치는 영향 분석 : 수도권·비수도권간의 차이를 중심으로

Abstract

The purpose of this study is to investigate the impacts of compact city characteristics suggested for the sustainable urban form on transportation energy consumptions at the regional level, and to find the important factors for reduction of energy consumptions. The important reason to investigate the regional-level characteristics is that the characteristics of each city have different impacts on the energy consumptions. These include social, economic, and physical environments. To analyze the different factors affecting regional transportation energy consumptions, this study divides the 79 sample cities into two regional groups: Sudokwon and Non-Sudokwon areas. The correlation analysis at the regional level and the multiple regression analysis are typically used. The results show that the impacts of compact city characteristics on the energy consumptions are different between two groups. Specifically, compactness of job and mixed land use have strong relationship with the energy consumptions in the Sudokwon area, while size of population is the only factor for Non-Sudokwon area. The policy implications in this study are twofold: First, it is necessary to focus on different aspects of urban development and management for each city or regional district. Second, in case of the area with higher residential density, such as Sudokwon area,mixed land use should be more appropriate for the reduction of energy consumptions.
