초록

최근 심각한 차대 보행자의 교통사고로 인명피해가 발생함에도 불구하고 사고원인에 대한 과학적으로 정확히 규명하지 못해 사고처리에 대한 논쟁이 끊임없이 발생하여 경제적 손실 및 정신적 고통이 가중되고 있다. 본 연구에서는 차대보행자의 교통사고분석을 위해 객관적인 교통사고관련 물적 증거자료를 토대로 차량공학, 주행역학), 충돌역학, 교통 및 도로공학 등을 검토하였고, PC-Crash 프로그램을 이용하여 충돌전 차량의 충돌초기속도, 진행궤적 및 충돌자세, 충돌전후속도, 충돌지점 등의 인자를 적용한 결과를 얻어 교통사고의 원인을 분석하였다. 그 결과로 스키드마크 및 보행자 충돌속도는 이론값과 비교할 때 각각 11.2%, 2.27%의 오차를 얻었다.

In spite of serious injuries caused by traffic accidents of car-pedestrian, the dispute is constantly occurring and economic losses and mental suffering is escalating since the cause of accidents is not scientifically identified. This study reviewed vehicle dynamics, driving dynamics, collision dynamics, traffic and road engineering for traffic accidents analysis based on traffic accidents related physically objective evidence and analysed the cause of accidents by getting results which applied vehicle initial collision velocity before collision, processing trajectory, collision stance, vehicle velocity before & after collision and parameter by using PC-Crash program. I found that skid mark and collision velocity of car-pedestrian had the error of 11.2%, 2,27% compared to theoretical values.
