EXPERIENCE TO DATE WITH IMPACT ATTENUATORS

LAST YEAR APPROXIMATELY 20,000 PEOPLE WERE KILLED IN ACCIDENTS IN WHICH THEIR VEHICLE LEFT THE ROAD. RECENT EXPERIENCE VERIFIES THAT OFF-ROAD ACCIDENTS ARE THE LEADING SOURCE OF FATALITIES ON INTERSTATE AND OTHER FREEWAYS. IN ADDITION, MORE THAN 40 PERCENT OF INTERSTATE FATAL ACCIDENTS INVOLVED A RIGID ROADSIDE OBSTACLE. AMONG THE EFFORTS TO REDUCE THIS TOLL HAS BEEN THE DEVELOPMENT AND INSTALLATION OF IMPACT ATTENUATORS (SOMETIMES CALLED CRASH CUSHIONS OR ENERGY-ABSORBING BARRIERS) IN A NUMBER OF STATES AT LOCATIONS SUCH AS EXIT RAMPS ON BRIDGES. THIS REPORT CONTAINS CURRENT INFORMATION ON RESEARCH IN THIS AREA. /AUTHOR/
