ABSTRACT:
Flexible elongate web structures with reflective faces are fixed on opposing ends of a support arm which is centrally mounted over a highway barrier. Appropriate geometric structure and material selection provide a non-destructive bending response for the respective web structures during vehicle impact and provide for restoration to original orientation. The support or mounting arm is formed of polymer material having sufficient rigidity to support the web structure during static conditions and sufficient compliance and flexibility to bend and twist during the vehicle impact.
