Samenvatting
A comprehensive program of full-scale automobile crash tests of highway appurtenances and evaluations of their performance was conducted. 2250 and 4500-Ib automobiles were used. The median barrier consisted of two standard corrugated sheet steel beams mounted on the ends of spacers which were in turn mounted on the top of weak posts. This barrier was developed in Europe and has been referred to as the SWOV or NEHER barrier. Four, full-scale, head-on impact tests were conducted on this terminal. Results of the first test showed that a design modification was necessary to prevent snagging of the vehicle on the foundation of the break-away end post. The remaining three tests were conducted on the modified design.
