<p>Acrashworthy traffic noise barrier system (10) for use alongside a path of traffic (12), the crashworthy traffic noise barrier system (10) comprises a crashworthy longitudinal barrier (14) extending substantially parallel to the path of traffic (12) and a crashworthy traffic noise barrier wall (16) supported by the longitudinal barrier (14). The crashworthy traffic noise barrier wall (16) includes a plurality of upstanding posts (24) attached to the traffic noise barrier wall (16), at least one panel (26) supported between each adjacent pair of posts (24) in the plurality of upstanding posts (24), and at least one longitudinal beam (32, 34, 36)s spaced above a top surface (22) of the longitudinal barrier (14) and extending across the plurality of upstanding posts (24) for redirecting a portion of an errant vehicle away from the at least one panel (26). The longitudinal beam (32, 34, 36)s redirect energy of the errant vehicle away from the panels (26),such that the panels (26) and any fragments of the panels (16) remain attached to the traffic noise barrier wall (16). The panels (26) may be transparent and may be reinforced with plastic bands, plastic threads, or a plastic net (27).</p> |
