ABSTRACT:
A roadway impact attenuator adapted to be installed between lanes on a highway or in advance of a barrier on the highway includes a number of substantially identical units each of which has a framework slidably resting on the ground or pavement, and spaced from the barrier or from a similar framework. An energy converting means is disposed between the barrier and the framework. The framework is related to the ground by a ground anchor secured thereto and releasably connected to the framework. Additionally, overlapped side panels are mounted generally horizontally along the sides of the framework, being secured thereto and being secured to similar panels on other frameworks in a telescoping relationship.
