State‐of‐the‐Art: Centerline Rumble Strips Usage in the United States

Centerline Rumble Strips (CLRS) are used to avoid cross-over roadway departures, making rural highways safer. The objectives of this study were to obtain nationwide, updated information about states’ policies and guidelines for utilization of CLRS and to provide a list of gaps in research along with good practices. Results indicate that 36 states reported the use of CLRS. The total CLRS approximate mileage is 11,333 miles. The predominant CLRS pattern is: milled, length 16”, width 7”, depth 0.5”, spacing 12”, continuous. This survey reported that 17 states have written policies or guidelines. A list of good practices used by the states is presented.
