KSU surveyed U.S. and Canadian provinces and found no serious negative problems with centerline rumble strips (CLRS) and recommended that they be field tested. KSU field tested several patterns of rumble strips, i.e., varying width and spacing. After selecting the best patterns, KDOT installed about 15 mi of two patterns of on the centerline of a two-lane state highway. This K-TRAN report summarizes the findings of safety benefits and non-benefits from this nationwide survey. It describes research on the Kansas test patterns leading to recommendations on the best patterns, and the results and conclusions of field testing of these patterns regarding drivers' acceptance and perceived benefits of CLRS.

This report provides guidance for the design and application of shoulder and centerline rumble strips as an effective crash reduction measure, while minimizing adverse effects for motorcyclists, bicyclists, and nearby residents. Using the results of previous studies and the research conducted under this project, safety effectiveness estimates were developed for shoulder rumble strips on rural freeways and rural two-lane roads and for centerline rumble strips on rural and urban two-lane roads.

In the United States, 60 percent of fatal accidents occur on rural roads. Among these, 90 percent occur on two-lane roads, and 20 percent of these accidents involve two vehicles traveling in opposite directions, totaling 4,500 fatal accidents per year. Centerline Rumble Strips (CLRS) are primarily installed on the centerline of undivided, two lane, two-way highways, and their main purpose is reduction of crossover accidents, specifically head-on and opposite direction sideswipe accidents, which are usually caused by driver inattention and/or drowsiness. Several authors have reported advantages other than reducing accidents in installing CLRS, such as a high benefit cost ratio, improvement of lateral vehicle position to the right, low interference in passing maneuvers, versatile installation conditions, and public approval. However, some concerns involving CLRS, such as disturbing noise for nearby residents, decreased visibility of the painted strips, faster pavement deterioration, potential driver erratic maneuvers to the left after encountering CLRS, and ice formation in the grooves, have been cited in the current literature. The objective of this report is to summarize results of three studies conducted by Kansas State University in 2008 and 2009; addressing some of the above mentioned concerns related to the installations of CLRS. Centerline Rumble Strips do increase the levels of external noise. Based on analysis using a light and medium vehicle, a distance of 200 feet from centerline should be considered. This is the distance where noise from CLRS is no longer greater than smooth pavement. This study applied three methods of evaluating the visibility of pavement markings. Based only on the limited data collected, it can be concluded that the coverage check method should not substitute the retroreflectometer readings for studies of retroreflectivity, since the correlation of the two methods was not reliable. In addition, the spectrometry method should only be used as a complementary analysis. The spectrometry method revealed that the yellow pavement markings remained within the yellow spectrum over the study period at all three locations.

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 339: Centerline Rumble Strips (CLRS) examines current design, installation, configuration, dimension, and visibility issues associated with CLRS. The report addresses the need for guidance on warrants, benefits, successful practices, and concerns such as external noise and the reduced visibility of centerline striping material. Also addressed are pavement deterioration, ice buildup in the grooves, adverse impact on emergency vehicles, and the effect of CLRS on bicyclists. Particular attention was paid to available before-and-after CLRS installation crash data to document the safety aspects of CLRS and the availability of policies, guidelines, warrants, and costs regarding their use and design.

Centerline rumble strips are being installed on rural Minnesota Highways in an effort to reduce crossover accidents. This study looks for possible detrimental effects on 2 and 3 wheeled cycles. Motorcycle accidents reports since centerline rumble strips first appeared on rural highways in 1999 revealed only 29 accidents on roads with the rumble strips. None of these reports implicated the rumble strips as a factor in the accident. There were also no visible indications of rider correction or overcorrection in 40 hours of roadside observations. Controlled conditions on a closed circuit supported this observation through 32 riders in all types of cycles and experience levels from 0 to 41 years of street riding. Interviews confirmed that the riders had no difficulty or concern with the rumble strips. The recommendation from this study is that cyclist should become familiar with the rumble strips in rider safety courses and driving examinations. There were no indications to impede the installation of rumble strips and no indication that signage is justified.

This report presents an evaluation of centerline rumble strips on a two-lane mountain highway. Accident data before and after construction is given to demonstrate the improvement in safety. Visual evaluations of the effects of the rumble strips on the condition of the pavement and centerline striping are given. Centerline rumble strips are recommended for installation on two-lane highways where there is a history of crossover (head-on and sideswipe from opposite directions) type accidents.
