Abstract
A traffic control device, such as a traffic signal light housing, with a resiliently deformable back plate assembly. The backplate assembly comprises side flanges that bend or deform in response to external forces such as high winds and blowing debris. In one embodiment, rigid side flanges include a hinge or joint formed of an elastomeric material. This multi-directional wind-dampening backplate renders the housing more aerodynamic and benefits the entire signal structure, including mast arms, poles, and span wire systems.
