SIMULATION OF CAR-PEDESTRIAN CRASH: INJURY ASSESSMENT AND IMPACT POSITIONS

In car-pedestrian collisions, pedestrian fatal injuries account for a great number of health risks in the world. A real-world accident case with a medical examination record would improve the reliability of simulation of car-pedestrian accidents but is rarely captured. The goal of this report was to assess the pedestrian injuries, and impact positions. A case of a pedestrian impacted by a car traveling at a speed of 22 km/hr was simulated using the MAthematical DYnamic MOdel (MADYMO) program. The results showed that Abbreviated Injury Score one (AIS1) head injury and Abbreviated Injury Score two (AIS2) toe fracture are caused by pedestrian impact with windshield and wheel. The maximum head linear acceleration and right foot force that led to head injuries and toe fractures are 1688.61 m/s2 and 15799.00 N, respectively. The results obtained in terms of head impact location, left forearm impact, and the right foot impact positions are comparable with the real-world road accident. This report can help in the future design of automobiles that are friendly to vulnerable pedestrians.
