Ten actual highway accidents have been mathematically reconstructed in a process comprised of two parts. First, trajectories of the vehicles were reconstructed from physical evidence observed at the scene, using a computer simulation of a two-vehicle, planar collision. Next, the responses of the right front occupant of the subject vehicle were reconstructed from observed internal vehicle damage and passenger injuries, using the predicted vehicle crash history and a nonplanar mathematical model of the crash victim. Following this analytical effort, the ten accident cases were physically reconstructed on an impact sled, using a sled pulse corresponding to the predicted vehicle deceleration history and an anthropometric crash test dummy to represent the accident victim. The results of most of the sled tests agree generally with observations from the actual crash and the results from the analytical reconstructions of crash victim responses. A correlation is shown to exist between observed injury and predicted vehicle speed change. (Modified author abstract)
