Ten impact tests were carried out on alternative constructions of cable and chain-link barriers, similar to one originally developed in California in 1959 for use on central reservations at least 16 feet wide. In this American barrier, two steel cables are clamped one either side of a line of steel posts, the intention being that under impact loading the cables should press into the bodywork of the vehicle to redirect it, their initial height above the ground being maintained at the vehicle by virtue of the fact that they slide off the ends of posts which bend ahead of the vehicle. The tests consisted in guiding cars, usually by remote control, into barriers 200 feet in length, photographing the vehicle-barrier responses, and measurthe ing vehicle decelerations. Speeds up to 60 miles an hour, and angles up to 20 degrees to the line of barrier were employed. (Author)
