Abstract

In order to stop a moving vehicle without injury to occupants, a vehicle barrier is provided having a pair of platforms disposed on opposite sides of a roadway, and a capture net extending across the roadway between the platforms. Each platform has a rotatably mounted spool attached to a different end of the net, and a dual acting extension-compression shock absorber pivotally mounted to the spool, such that when the force or energy of an impacting vehicle on the net is applied to the shock absorbers, via rotation of the spools. Rotation of spools operate the shock absorbers in compression, and if needed, in extension. In railroad crossing application, two of the vehicle barriers are provided on either side of the railroad tracks to prevent vehicles from crossing the railroad tracks.
