Abstract:

WSDOT began installing rumble strips on undivided highways in 1999 as a countermeasure for roadway

departure crashes. Installations on the shoulders were intended to reduce run-off-the-road crashes, while

centerline rumble strips targeted reductions in cross-centerline crashes. A March 2011 report detailed the

performance of centerline rumble strips on Washington State highways. This study:

• Examines the combined effects of centerline and shoulder rumble strips.

• Details the performance of rumble strips on undivided highways in Washington State under

a variety of conditions.

• Explores various traffic volumes, geometric conditions, lane and shoulder widths, and driver

contributing circumstances.

• Compares various installation scenarios with shoulder and centerline rumble strip installation

at different times, as well as simultaneous installation.
