This article briefly describes some 'reusable' crash cushions that have been developed in response to the escalating costs which are limiting the use of conventional crash cushions in the USA. Although they are second only to seat belts in preventing road fatalities in the USA, conventional crash cushions have very high repair and replacement costs. At the same time, compensation payable for a fatality can exceed $1 million. Early in 1995, Roadway International introduced its REACT 350 (Reusable Energy Absorbing Crash Terminal), a cushion that uses 'indestructible' high-density polyethylene barrels to absorb the energy of frontal collisions, and steel cables to redirect a vehicle in high-speed side impacts. It was tested to the demanding NCHRP 350 (National Cooperative Highway Research Program 350) specifications, a new testing format defining recommended procedures for the safety performance evaluation of highway features in the USA. Another American company, Energy Absorption Systems, recently introduced Cushionwall as a road safety device designed for high-frequency lateral impact areas. Each of Cushionwall's sections contains 12 energy-absorbing reusable elastomeric cylinders supported by a steel framework and by steel cables.
