Abstract

Due to the recent widespread of COVID-19 in South Korea, the Korean government runs the multiple permanent COVID-19 testing sites and has added temporary testing sites throughout the Seoul Metropolitan area. Such testing sites, however, are spatially unevenly distributed. It may be responsible for spatial inequality of the access to the testing sites for people. To address this issue, this study measures the spatial accessibility to the COVID-19 testing sites in Seoul based on an enhanced two-step floating catchment area method. It extensively considers not only multiple transportation modes(i.e., driving and walking) but also the characteristics of population(i.e., daytime and residential population). As a result, it is shown that the temporary testing sites help to increase the overall accessibility and its spatial inequality for people. However, the increase in the spatial accessibility is neglected in the peripheral regions and the inequality persists. Therefore, the results indicate that the temporary testing sites should be maintained in the regions where a high level of differences exists. This study highlights that measuring spatial accessibility would help the spatial allocation of testing sites for preparedness and controls of the future pandemic.

우리나라 정부는 국민들의 코로나-19 감염여부를 확인하기 위해 상설선별진료소를 운영하고 있다. 2020년 11월, 코로나-19의 3차 대유행으로 인해 12월 중순 임시선별진료소를 추가로 배치하였다. 하지만 이러한 진료소와 검사소의 분포는 공간적으로 불균등하게 분포되어 있어 사람들의 진료소･검사소에 대한 공간적 접근성 또한 공간적으로 불평등할 것으로 판단된다. 이에 본 연구는 E2SFCA 방법을 활용하여 공간적 접근성에 대한 임시선별검사소의 추가적인 배치의 영향을 확인하고자 한다. 이를 위해 두 가지 교통수단(자가용, 도보)과 인구 분포의 특성을 고려하였다. 결과로써, 임시선별검사소의 추가적인 배치로 인해 서울시 전역의 접근성이 전반적으로 향상되었고, 불평등 또한 해소된 것을 확인하였다. 또한 추가적인 임시선별검사소의 배치에 따라 접근성 차이가 큰 지역을 대상으로는 임시선별검사소가 지속적으로 배치될 필요가 있다는 것을 보여준다. 따라서 본 연구는 앞으로 코로나-19와 같은 감염병의 대유행이 발생했을 때의 검사소 배치에 대한 공간적 관점의 중요성을 강조하고 있다.
