| 초록 |
Demanding excessive settlement or claim for medical expenses when a victim is injured by WAD (Whiplash Associated Disorders) in a minor traffic accident that collided at low-speed comprises a social problem. Experimental studies on the possibility of injury on a rear-end collision at low-speed had been conducted in and out of the country. As the results of these studies showed, the change in speed of the struck vehicle is the most important factor determining whether the occupants are injured or not. In order to estimate the change in speed of the struck vehicle, one needs the coefficient of restitution that fits the low-speed rear-end impact cases. In this study, we used five vehicles to measure the speed changes in the vehicles in line with six low-speed rear-end collision cases with about 8 km/h speed change in the struck vehicles. We obtain the coefficient of restitution in low-speed collision situations and verify the reliability of the coefficient of restitution by applying this to PC-Crash simulation, a traffic accident analysis program. |
