Rumble Strip Noise Evaluation

Status:  Complete
Report Date:  02/18/2015

California's wave-shaped design produced less external noise than MnDOT's current design, and generated tones that are likely to be less abrupt in a rural environment, while producing an adequate amount of sound inside a vehicle to alert drivers.
