Abstract
A crash cushion includes a number of spaced-apart supports or bulkheads; energy absorbing modules positioned between the supports; overlapping side panels that interconnect the supports and envelop the energy absorbing modules; front and rear fixed anchors; and reinforcing cables extending between the anchors. The cables extend through cable guides formed in the supports so as to stabilize the supports and facilitate controlled collapse of the supports during vehicle impacts.
