SUMMARY OF CRASH CUSHION EXPERIENCE IN TEXAS--FOUR HUNDRED COLLISIONS IN SEVEN YEARS ON ONE HUNDRED THIRTY-FIVE INSTALLATIONS

Steel drum crash cushions (both fixed and portable) and the sand inertia barrier have made and will continue to make important contributions to the safety of our state's and nation's highways. Texas first installed the steel drum crash cushion in October 1968. As of July 1, 1975, 147 crash cushions of all types were in use on Texas highways. These crash cushions have sustained over 400 vehicle impacts since the first installation more than seven years ago. Researchers from TTI and the State Department of Highway and Public Transportation visited seven districts that had widely used the crash cushions to see if changes or improvements were needed. Discussions were held with traffic engineers, maintenance engineers, foremen and shop supervisors. As a result of these discussions and accident data gathered several changes or improvements were developed which should increase the safety and economy of the devices.
