Abstract

Since spatial accessibility of 119 emergency services is affected by road traffic conditions, temporal variability should be considered in spatial accessibility analysis. This study analyzed the temporal change characteristics of the spatial accessibility of 119 emergency services for the elderly population in Daegu by reflecting real-time traffic conditions in the 2SFCA (2 Step Floating Catchment Area) accessibility measurement. As a result of analyzing the spatial accessibility index by dividing it into 4 grades, the spatial accessibility of the 119 emergency service for the elderly population showed a similar spatial distribution at the morning/afternoon peak. As a result of the analysis applying the Accessibility Time Index (ATI), which reflects the degree of change in traffic conditions during the day, the ATI grade 1 and grade 4 areas show different spatial distributions in the morning and afternoon. In this study, it was confirmed that the 4th grade area was spatially more widely distributed at the peak of the afternoon. Since the ATI information is an index that analyzes the changes in spatial accessibility of 119 emergency services by time, it can be evaluated that it provides useful information for setting up customized supplementary measures for each time period.

119구급서비스 공간적 접근성은 도로 교통상황에 영향을 받기 때문에 공간적 접근성 분석에는 시간적 변동성을 고려해야 한다. 이 연구는 2SFCA(2 Step Floating Catchment Area) 접근성 측정에 실시간 교통상황을 반영하여 대구시 고령인구의 119구급서비스 공간적 접근성에 대한 시간적 변화 특성을 분석하였다. 공간적 접근성 지수를 4등급으로 구분하여 분석한 결과, 고령인구의 119구급서비스 공간적 접근성은 오전/오후 첨두시에 비슷한 공간 분포를 보여주었다. 지역별 교통상황이 하루 중에 변화하는 정도를 반영하는 접근성시간지수(Accessibility Time Index: ATI)를 적용한 분석 결과, ATI 1등급 지역과 4등급 지역은 오전첨두시와 오후첨두시에 각각 다른 공간 분포를 보여주고 있다. 이 연구에서는 오후 첨두시에 4등급 지역이 공간적으로 더 넓게 분포하는 것을 확인할 수 있었다. ATI 정보는 119구급서비스의 공간적 접근성이 시간대별로 변화하는 양상을 분석하는 지표이기 때문에 시간대별 맞춤형 보완 대책을 세우는데 유용한 정보를 제공한다고 평가할 수 있다.
