Evaluation of New Rumble Strip Designs to Reduce Roadside Noise and Promote Safety

Noise from vehicles passing over rumble strips is a major source of complaints from residents living
adjacent to highways in Washington state. This project evaluated wayside noise levels from various
new centerline and shoulder rumble strip designs to determine overall sound levels and 1/3-octave band
frequencies. Results suggest that some designs can have lower exterior sound levels and sufficient
interior sound levels. This report does not recommend a specific design; WSDOT will determine how to
use the results of this research in future decisions about rumble strip design.
