• 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.
