Development of a Novel Aerodynamic Solution to Mitigate Large Vibrations in Traffic Signal Structures

Structural supports of signs, luminaires, and traffic signals are an integral part of the transportation system. The promising results in this analysis present an opportunity to address the longstanding issue of fatigue-related failures in traffic signal structures.

The TRB Highway Innovations Deserving Exploratory Analysis (IDEA) Program's Development of a Novel Aerodynamic Solution to Mitigate Large Vibrations in Traffic Signal Structures considers “aerodynamic damping” as an active means to mitigate the large amplitude vibrations of these structures.
