세종시 개발에 따른 세종시와 인접지역 간 인구이동 및 통행 변화

Abstract

The development of massive newtown generally brings about various changes in pre-established urban structure, function, population change, and supply and demand of houses. The establishment and development of Administrative City Sejong where central public administrative offices are located started to spark tremendous changes in the neighboring area as expected. The first stage based on the relocation of governmental offices and formation of infrastructures was completed in 2015. Currently the fundamental premise of the second stage development project, undertaken from 2016, is to expand self-sufficient functions. This study attempts to examine not only population migration but daily trip patterns. First, the move-in population in Gongju showed a constrictive square pyramid compared to neighboring areas, although the characteristics of immigrated population in Sejong revealed a star-shaped (urban type) population pyramid commonly represented in cities or new developed areas into which young adults move. Second, Cheongju and Cheonan are overflowing cities, while Yuseong and Gongju are over-outflowing cities as interlocal daily trip patterns showed. Third, for the change of daily traffic amounts between Sejong, the connected rank of traffic amounts between cities was shifted from Cheongju-Gongju-Yuseong-Gongju to Cheongju-Cheonan-Yuseong-Gongju amid the rapid increasing total traffic amounts after establishing Sejong. Lastly, traffic amounts in accordance with trip objectives and main directions showed different characteristics according to regions. Therefore, Sejong must consider the development plans of Neighboring Area even though Sejong aim for Self-sufficiency.
