In the event of a pedestrian accident, the pedestrian is at high risk of severe injury that may result in death due to lack of safety equipment. In a pedestrian accident, both the impact position of the pedestrian and vehicle velocity just before the impact are important factors that need to be calculated. The accident is reliably recreated through the MADYMO simulation by using the speed before the impact, the injured area of the pedestrian, and the damaged state of the vehicle. However, the reliability and utilization of MADYMO are not yet confirmed. Therefore, this paper recreated the accident by using MADYMO in order to demonstrate the reliability and utilization of the simulation results under the situation where the accident video exists. The initial impact position and dummy posture were set by using accident videos and photos of the damaged vehicle. Furthermore, vehicle speed was calculated by investigating the accident video and considering the thrown distance of the pedestrian. Through the MADYMO simulation, the thrown distance of the human dummy model was compared with a real accident. In addition, the difference between the pedestrian behavior and dummy model’s behavior was compared. This study indicates that the MADYMO is reliable in using simulation results based on thrown distance, physical evidence, etc. |
