In analyzing road accidents, it is important to estimate the vehicle behavior and the occupant movement according to the accident site conditions, such as the final vehicle rest position, damage profiles and tire scuffs. For this research, a two-dimensional car-to-car collision model, in which vehicle crash properties and tire forces are considered, has been developed to predict accelerations, deformations, trajectories and tire yawmarks of each vehicle. Further, a two-dimensional occupant model with one mass and three degrees of freedom in consideration of deformation properties of human body has been developed and incorporated in the vehicle collision model, in order to analyze the occupant crash victim.In this report, calculation formulas are described, and numerical solutions obtained by the model are compared with those of the crash experiments. It is found that a considerably good agreement exists between both data, and that this model may be used as a computerized accident analysis method.
