Actual Vs. Isolated CSRS and Centerline Rumble Strips Effectiveness
Given behavior adaptation and migration, the current rigorous Interstate effectiveness of 14% and CLRS on single-lane highways effectiveness of 14% could be over-estimations of the actual "big-picture" reduction. In certain situations, such as an engaging single-lane highways that typically have narrow shoulders, high precipitation, in a northern climate with frequent freeze-thaw cycles, rumble strip effectiveness may be negative.
As before-and-after studies become broader and more sophisticated it appears the reduction estimates for both CSRS and centerline rumble strips are less impressive. This may be due to the initial installations were on highways that had been identified as having very high accident rates due to inattention. Also, there may have been other accident reduction campaigns in concert with rumble strip programs."
Also, as lane departure warning systems become more widespread the physical CSRS, centerline rumble strips CLRS may be become increasingly redundant.
