The Modular Crash Cushion, composed of 55-gallon steel barrels, was developed to decrease the severity of vehicle collisions with these gore obstacles. Three concrete abutment gore locations were the scene of eight fatal accidents reported during the period from September 1965 through October 1968. Modular Crash Cushions were installed at these three locations as well as at two other gore positions in late October 1968. Records show there have been thirteen accidents involving these installations through October 1969 with no serious injuries nor fatalities at any of these sites. As a result of this study, the following general conclusions were drawn: The modular crash cushions performed as designed; they effectively reduced the collision severity, as indicated by the thirteen reported crashes, to the extent that no fatalities or serious injuries occurred. At existing elevated exit ramps the greatest portion of the total initial cost, site modification, can be greatly reduced on new freeway construction by designing elevated gores to accept the modular crash cushion during initial construction. Maintenance costs are minimal and repair costs are resonable. Appearance is unobtrusive. This safety device was readily accepted by the public, police, news media, and highway engineers. (Author)
