ABSTRACT:
A vehicle crash barrier for decelerating a vehicle that has left a roadway includes an elongated frame having a number of sections including a front section and at least one additional section arranged end to end along an axial direction. The frame is configured to collapse when axially struck on the front section by a vehicle. A wire cable extends generally parallel to the frame and has a forward end portion anchored independently of the frame and a rearward end portion. Friction brakes are mounted to the front section for engaging the wire cable to generate a retarding force to decelerate a vehicle as the brake moves along the wire cable during collapse of the frame following impact of the vehicle against the front section. Each section includes a pair of side panels, and axially adjacent side panels are connected by a flexible tension strap by fasteners. The tension strap operates to peel the fasteners out of the side panels during axial collapse. The front section is releasably secured to a ground anchor by a directionally sensitive breakaway assembly.
