The objective of this research was to determine whether the presence of transverse rumble strips is an effective warning device for drivers approaching rural stop-controlled intersections. Rural highways are associated with long tangents and infrequent intersections, which can cause drivers to become inattentive. To evaluate the effectiveness of transverse rumble strips, vehicle speeds were measured at three locations along the approach to rural stop-controlled intersections both before and after the installation of transverse rumble strips. The researchers evaluated nine rural stop-controlled intersection approaches in Texas during both day and night conditions on both weekends and weekdays. Overall, the installation of transverse rumble strips generally produced small but statistically significant (p .05) reductions in approach speeds. There were no clear indications that the transverse rumble strips had a greater or smaller impact during day, night, weekend, or weekday periods. In a few instances, speed change reductions of greater than 1 mph occurred; however, the overall trend was for speed change reductions to be equal to or less than 1 mph.
