In this study, the accident scene and vehicle damage data are used together with results from rollover tests and computer simulation and computer graphics to reconstruct the vehicle path and vehicle dynamics in three dimensions. The significant previous papers, which provide the scientific basis for rollover accident reconstruction, are discussed with regard as to how this knowledge can be applied using Human-Vehicle-Environment (HVE) and three-dimensional (3-D) Studio MAX2. The use of HVE and 3-D Studio MAX in conjunction with the traditional methods enables the reconstruction to be done in three dimensions with a detailed analysis of linear and angular velocities and accelerations. Using HVE it is possible to analyze driver inputs leading to the rollover and the occupant kinematics during the rollover. The methodology is illustrated with examples utilizing 3-D terrain and actual accident data to show how the simulation and graphics are utilized in the analysis and in the presentation of the vehicle's motion including tire forces and suspension dynamics in real-time. The understanding and visualization of these important characteristics is more easily achieved than by using traditional methods.
