Transverse Rumble Strips at Rural Intersections

Status: Complete
Report Date: 06/01/2023

Summary:

Fatal crash rates are two times higher in rural areas than in urban areas. A substantial portion of rural crashes happen at intersections due to high speeds and drivers failing to stop. Transverse rumble strips, which run across a traffic lane, are a low-cost and easily deployable safety countermeasure for intersection approaches. While some studies have shown transverse rumble strips are effective at slowing speeds and encouraging stopping, there is little consistency in placement or design. This research evaluated which transverse rumble strip designs are most effective in changing driver behaviors.
