인구격자 셀 버퍼공간 설정에 의한 기반시설부담구역경계 검토방안 연구

인구격자 버퍼 분석으로 기반시설부담구역 경계 설정 방안을 검토했다.

Recently, the Korean government has amended the “National Territory Planning Act” by adding criteria to designate the Impact Fee Zone on the basis of the population increase rate. Taking the Dongtan Newtown in Hwasung City as the case, the study first tries to apply a grid analysis method to figure out the cells that exceed the legal population increase rate criteria. Then, the study, for rather a practical purpose, introduces a scenario analysis that tries to envelope the cells into a spatially contiguous groups based on their degrees of stepwise adjacency by cell buffer formation.

By overlapping the selected cell groups chosen by such stepwise scenarios over the actual zoning map of land-uses for the vicinity, it seems clear that the chosen areas rationally coincide with those residential blocks and commercial areas with the high population density in the Newtown.
