Abstract

The potential for rollover after a vehicle has collided with a roadside barrier is greatest for vehicles that have a high center of gravity, such as school buses, intercity buses, and trucks. There are various computer programs that can simulate vehicle-barrier interaction, but they can be expensive to run and do not address the phenomenon of cargo displacement during vehicle impact with a roadside barrier. A computer program that can be used to estimate the effect of cargo displacement on secondary-impact vehicle roll response is described. It is applied to delineate the rollover potential of a school bus carrying unrestrained children during a collision with a highway barrier.
