Computer simulations of occupant dynamics are ideal for conducting parametric studies evaluating injury countermeasures. A rollover accident was selected from the National Accident Sampling System (NASS) for simulation to validate the Articulated Total Body (ATB) model's capability to predict occupant dynamics during rollover accidents and to gain insight into injury mechanisms. Simulation of both the driver and the passenger occupants which may be used in future countermeasure studies were performed. In the selected accident, a pickup truck rolled multiple times, the belted driver had minor injuries, the unrestrained passenger was ejected with fatal injuries. The body properties for both occupants were obtained using the Generator of Body Data (GEBOD) program based on their weights, heights and sexes. The simulation successfully predicted the passenger's ejection and the driver's minimal impacts.
