Abstract

eCall system assists traffic accident victims by connecting emergency rescue institutions with accurate accident information, helping them to identify the on-site situation in the event of a traffic accident. The purpose of this paper is to develop a Korean eCall system that reflects the requirements of domestic emergency rescue institutions and to analyze the expected effects through an integrated demonstration. The results of an integrated demonstration indicated that the communication success rate between the eCall IVS and the call center was 99.25%, and the average location information error was 1.2 m. In particular, it has been confirmed that the average location information error is less than 21.6 meters, as assessed by the Korea Communications Commission when evaluating the accuracy of domestic emergency rescue location information. When the eCall system was introduced, it was confirmed that the time from traffic accidents to hospital arrival could be shortened by 3 m 38 s for highways and 1 m 22 s for general roads. By it to traffic deaths from 2005 to 2022, it was analyzed that the number of fatalities decreased by 82,662, resulting in a reduction of approximately social costs.

eCall은 교통사고 발생 시 긴급구난 기관과 현장상황을 정확하게 파악할 수 있는 사고정보를 연계하여 교통사고 피해자를 신속하게 구조·구급하도록 지원하는 시스템을 말한다. 본 논문의 목적은 국내 긴급구난 기관의 요구사항을 반영한 한국형 eCall 시스템을 개발하고 통합실증을 통해 기대효과를 분석하는 것이다. 통합실증은 전국을 대상으로 진행되었고, 통합실증 결과 eCall IVS와 센터 간 통신성공율은 99.25%, 위치정보 평균 오차는 1.2 m로 측정되었다. 특히, 위치정보 평균 오차는 방송통신위원회의 국내 긴급구조 위치정보 품질 측정 결과인 21.6 m 보다 우수한 것을 확인할 수 있었다. eCall 시스템이 도입 시 교통사고 발생부터 병원도착까지 시간은 고속도로는 3분 38초, 일반도로는 1분 22초 단축 가능하다는 것을 확인할 수 있었다. 이를 2005년부터 2022까지의 교통사고 사망자에 적용한 결과 교통사고 사망자 수는 82,662명, 사회적 비용은 약1,026,100천달러가 감소되는 것으로 분석되었다.
