Abstract:
A barrier system is provided for absorbing the forces generated during collisions with vehicles. The system includes a plurality of interconnectable modular blocks that have a controlled rate of compression. The blocks connect with one another while allowing pivotable movement. In addition, an anchor system is provided that allows one or more blocks to be secured to the ground or to the floor, while still allowing the secured blocks some degree of pivotable movement.
