Abstract

Accident records were compiled over a 5-year period (1971-1975) to evaluate performance of light-post guiderail and median barrier, slipbase sign posts, frangible-base luminaire supports, and impact attenuation devices. Guiderail and median barrier injury rates were very low, with only eight serious injuries and no fatalities recorded in 392 accidents. Penetration of the barrier occurred in only 4 percent of mid-section accidents. Based on only 10 accidents, slip-base sign supports appear to be performing satisfactorily. Based on 78 accidents, performance of aluminum frangible-base luminaire supports is excellent. Of 393 impacts recorded on four types of attenuators, only six severe injuries and one fatality occurred; most serious accidents were related to specific problems with individual attenuators or with secondary collisions.
