ABSTRACT:
An energy absorbing guardrail crash attenuator system comprises a row of two or more compressible sections comprising left and right curved, metal side panels. The row of compressible sections extends in an axial direction from a front end and terminates in a back end that is engagable with a rigid backup. When the row is impacted by a vehicle in the axial direction, the compressible sections bend outwardly and absorb energy. When the row is impacted in a direction that is off of the axial direction, the row redirects the vehicle so as not to hit the "coffin corner" of the rigid backup. The front ends of the left and right metal panels are flexibly joined while the back ends are pivotly joined to the rearwardly adjacent section. The panels may have panel bending modifications for facilitating the axial compression of the sections. The row may have an axial movement guide to restrict lateral movement of the row of compressible sections. The front of the row may extend into an array of containers of particulate mass, such that the attenuation system performs gating and redirecting functions.
