Listening to a sine: Minnesota digs deeper into a rumble strip design
Results of sound-level monitoring of four types of centerline rumble strips installed along Trunk Highway (TH) 18 in Mille Lacs and Aitken counties in Minnesota are presented from the Sinusoidal (Sine) Rumble Strip Design Optimization Study. The study, along with one that was completed in 2015 comparing three alternative longitudinal edge-line rumble strips along two roadways in Polk County, MN, was undertaken in response to objections raised by some landowners about unwanted noise created by vehicles when they drift over the edge or centerline of the roadway over rumble strips. The sinusoidal wave-shaped rumble strip creates the necessary noise and vibration to alert the driver, but exterior noise level is reduced due to a less abrupt design than the standard Minnesota Department of Transportation (MnDOT) rumble strip.
