Transverse rumble strips (TRS), which run across a traffic lane, are a low-cost and easily deployable safety countermeasure for intersection approaches. Grooved into the pavement or installed as ridges on the surface, rumble strips provide an audible and tactile warning to drivers and are effective in all conditions but particularly when it’s dark or visibility is low. While some studies have shown TRS are effective at slowing speeds and encouraging stopping, there is little consistency in placement or design. Variables include the number of panels (or sets of strips), strips per panel, dimensions of strips and distances to traffic signs. To decrease crash risk, the Local Road Research Board wanted to understand which TRS designs are most effective in changing driver behaviors. The goal of this project was to evaluate the effectiveness of different TRS designs on driver speed and stopping behavior at rural intersections.
