Abstract
An energy absorbing roadside barrier includes an elongated container configured to receive and hold a volume of water. The container defines a pair of sidewalls having sufficient rigidity to stand alongside a roadway and sufficient resilience to deform upon an impact by a vehicle and to recover their shape after at least some impacts. The barrier also includes an internal frame positioned within the container. The frame includes first and second axial braces positioned adjacent respective sidewalls of the container, and the axial braces are secured together by at least one cross brace. The frame and container are formed of different materials, and the frame increases the rigidity of the barrier and strengthens the barrier against bending.
