Abstract: A computer simulation model of pedestrian-vehicle accidents was developed to analyze pedestrian-vehicle accident and vehicle safety research. The model was based on finite element method (FEM) and human dimensions and inertial parameters of Chinese adult human body. Human Body Model was set up for the men's 50 percentile which including 15 individual segments, and the vehicle model was simplified into the front-end outline structure which contact with the human body. The microscopic validation and the macro validation of the simulation model were verified compared with a real video of pedestrian-vehicle accident and theoretical results. Thus, the simulation model can estimate the vehicle velocity in pedestrian-vehicle accident and can be applied to a real traffic accident reconstruction.

Key words: pedestrian-vehicle accident reconstruction, simulation of finite element method, pedestrian dummy, parameters of Chinese human body
