For an effective design of crash cushion, understanding vehicle motion during impact and mechanical properties of the cushion is essential. In this paper, structural parameters affecting on the occupant safety have been identified and studied using 2-DOF System model describing vehicle crash against cushion with various mechanical properties. From the study two design equations have been developed, which can be used for the design of any crash cushion system with design conditions of 1.3ton vehicle head-on impact with 60km/h and 80km/h impact speeds.
