Abstract

Emergency Medical Service(EMS) has become focused due to all kinds of disaster and a great number of casualties. The 119 emergency vehicles' dispatching methods are now being focused, for travel time of ambulances are the critical components in terms of saving human lives. Therefore, this study tried to rearrange 119 EMS regions more efficiently. For this study, Daejeon Metropolitan City's real call cases were analyzed. In order to rearrange the regions, OD Cost Matrix analysis was performed between 800 thousands random points and 26 departments in the Daejoen Metropolitan City. By creating Thiessen Polygon from the random points, a new region was created. As a results, average areas of the regions were reduces from 32 square kilometers to 20 square kilometers, and average time of arrivals are were also improved. Hence, if related organizations plan to rearrange EMS regions, they may utilize this study.

최근 각종 재난재해로 인해 인명피해가 증가함에 따라 응급의료서비스의 중요성이 더욱 부각되고 있다. 이러한 응급의료서비스의 기본이 되는 119구급대의 이동 시간은 인명 구출의 핵심 요소라고 할 수 있으며, 이로 인해 119구급대의 효율적인 출동 방안에 대한 관심 또한 높아지고 있다. 따라서 본 연구에서는 GIS 네트워크 분석을 활용하여 119구급대의 출동 권역을 효율적으로 재조정하고자 하였다. 새로운 권역을 형성하기 위해 대전지역 경계 내에서 무작위로 생성한 약 80만 개의 가상 신고 위치와 26135개의 소방관서 위치를 기점으로 기종점 OD 행렬 분석을 실시하였으며, 이를 바탕으로 Thiessen Polygon을 생성함으로써 새로운 권역을 도출하였다. 그 결과, 각 소방관서로부터 신고 위치까지의 평균 이동 시간이 9.93분에서 5.53분으로, 4.4분이 단축되었으며, 면적의 경우 평균 $32.07km^2$에서 $20.72km^2$로, $11.35km^2$가 감소된 것을 확인할 수 있었다. 따라서 유관 기관에서 소방관서의 관할권역을 재조정하고자 하는 경우 본 연구가 유용하게 사용될 수 있을 것으로 보인다.
