Abstract

Among the driving information recorded in the event data recorder (EDR), the speed information of the vehicle before the traffic accident is a very important factor that determines the punishment of the driver of the accident vehicle, the identification of the offender and the victim, and the possibility of avoiding the accident. Also, by analyzing the EDR data, the deceleration of the accident vehicle can be analyzed. In this study, the results of the braking test of the previous study and the analysis of the EDR data of the traffic accident vehicle were compared to suggest an appropriate deceleration value applicable to the calculation of the stopping distance. As a result of the braking test of the vehicle equipped with ABS of the previous study, the average deceleration of the vehicle was 0.79g ~ 0.94g. In addition, the deceleration value was calculated from 0.92g to 0.94g in the recent automobile safety evaluation braking test conducted by the Korea Automobile Testing & Research Institute. In addition, the deceleration value of 0.55g ~ 0.71g was calculated through the analysis of EDR data performed in this study, and the value was smaller than the deceleration value measured in the braking experiment of the previous study.

사고기록장치(Event data recorder, EDR)에 기록된 운행정보 중 차량의 사고 이전 속도정보는 사고차량 운전자의 처벌, 가해자·피해자 구분, 사고회피 가능성 등을 결정하는 매우 중요한 요소이다. 또한 EDR 자료를 분석하면 사고차량의 감속도를 분석할 수 있다. 본 연구에서는 교통사고 분석에서 사고차량 운전자의 전방주의의무 이행 여부, 사고회피 가능성 등을 판단하는 주요요소인 정지거리 산출에 적용 가능한 적정 감속도 값을 제시하기 위하여 선행연구의 제동실험 결과와 교통사고차량의 EDR에서 추출한 자료를 분석한 결과를 비교하였다. 선행연구의 ABS 장착차량 제동실험을 분석 결과, 차량의 평균 감속도는 0.79g~0.94g로 나타났다. 또한 비교적 최근에 이루어진 교통안전공단 자동차 안전도평가 제동실험에서는 감속도 값이 0.92g~0.94g로 매우 높게 나타났다. 그리고, 본 연구에서 수행된 EDR 자료 분석을 통해서는 0.55g~0.71g의 감속도 값이 산출되었으며, 선행연구의 제동실험에서 측정된 감속도 값보다 작은 값이 나타났다.
