Listening to a sine

摘要

This study follows an extensive study completed in 2015 that compared three alternative longitudinal edge-line rumble strips along two roadways in Polk County, Minn., sponsored by the Minnesota Local Road Research Board. In the Polk County study, the California design provided adequate driver feedback while generating less exterior noise than the standard Minnesota Department of Transportation (MnDOT) design. The Pennsylvania design did not provide enough driver feedback even though it generated less exterior noise than either the California or Minnesota designs.
