Samenvatting
Pedestrian accidents raise the major problem of the severity of impacts from the head against the vehicle, the severity committed to the velocities of vehicle- pedestrian accidents. But the estimation of the velocities is delicate. The stopping distance of the vehicle just as the pedestrian projection give a first indication for the estimation of the velocity of the collision. Experimental reproductions of the subsequent deformations due to the impacts of the head found on the bonnet or the mud guards of the involved vehicles give, exept a comparison of criteria of injuries to the severity, of the delivered injury to the pedestrian, a complementary evaluation of the velocity of the collision.
