Abstract: In order to reduce damage to the pedestrians in the pedestrian-car collision process and discuss the mechanism by which the multiple factors influence pedestrian injury, a platform of vehicle crash simulation was established and a model was built. The effectiveness of the model was checked through real accident case information. The simulation platform was used to calculate pedestrian kinematics response and damage degree after collision under multivariate factor conditions. The research shows that injury caused by collision between the pedestrian head and the earth is the main cause of the pedestrian death, that there is a positive correlations between the shin acceleration or the bending angle of knee joint and closeness of height of the bumper to height of the shin, and that reducing the bumper incline angle can decrease the risk of pedestrian leg injuries.

Key words: pedestrian-car collision, kinematics response, pedestrian injury, multiple factors, simulation parameters design
