The Kansas Department of Transportation (KDOT) has installed rumble strips on the shoulders of most state highways in the state. However, Kansas has several miles of two-lane highway 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. Some US states have been experimenting with centerline rumble strips. KDOT wishes to install several test sections of centerline rumble strips (CLRS) and contracted with Kansas State University (KSU) to survey other states and summarize their experience and to develop a research design to evaluate KDOT test installation. The paper will summarize the findings from a nationwide survey. It will describe the Kansas test sections, the results of a survey of drivers and their acceptance and the results and conclusions of the field tests of the acceptance and benefits of CLRS.
