고령인구의 보행속도를 고려한 공공서비스시설별 접근성 분석: 대전광역시를 사례로

다국어 초록 (Multilingual Abstract)

The main purpose of this research is to analyze the accessibility to public service facilities in consideration of the walking speed of the elderly population and to derive areas with vulnerable access. The focus is on the Metropolitan City of Daejeon, which has recently had an aging population. The analysis was done by utilizing the data of the elderly population aged 65 years and over, Open Street Map, and the representative address data of each public service facility. Considering the walking speed of the elderly population, the areas with vulnerable accessibility were derived through Arc GIS Service Area analysis and bivariate spatial autocorrelation validation. According to the analysis results, most of the elderly residing in Daejeon City are distributed in the original downtown area, where Jugong apartments and detached houses are concentrated, and Gwanjeo-dong, where many Jugong apartments are built. This area has weak access to facilities related to medical care and poor welfare for the elderly. When establishing an urban spatial and environmental plan for Daejeon through such research, it is necessary to first consider areas with weak access to the original downtown area.
