Abstract:In the USA, shoulder rumble strips are very common. It is estimated that they reduce run-of-the-road crashes up to 25%. The Kansas Department of Transportation (KDOT) has installed rumble strips on the shoulders of almost all state highways in the state. However, Kansas has several miles of two-lane highways with no shoulder. These highways have a number of single vehicle run-of-the-road crashes (both sides) as well as crashes from cars going across the centerline and colliding with on-coming vehicles (crossover crashes). Some U.S. states have been using or experimenting with centerline rumble strips (CLRS). In most states that use them, they are used only on no-passing sections or curves. KDOT contracted with Kansas State University (KSU) to survey other states and summarize their experience and to develop a research design to evaluate KDOT test installations. /Abstract from report, p.
