Dynamic behavior of guard rails intended to resist vehicle impacts is discussed; by means of simple theoretical model, average lateral decelerations for car incident at 60 mph and 20° are estimated to be 6.7 g for rigid barrier, and 2.2 g for barrier which deflects 4 ft; measured vehicle decelerations against concrete and metal guard rails show peak values about 3 times average values.
