Book Description
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.

Book Description
The Run-off-the-Road (ROTR) type of accident has been a predominant factor in highway fatalities nationwide. This situation has created a major concern and challenge for traffic management within transportation departments. Shoulder rumble strips are new traffic control devices for interstate and limited access roadway systems, which hold great potential for reducing ROTR accidents. Consequently, they have become a critical and attractive subject for highway safety improvements. Although shoulder rumble strips have been recognized as an effective measure and have been widely tested by 35 state agencies and several countries, the rolled type rumble strip is found most often in the literature. The optimal design patterns among the available types and their effectiveness have not been quantitatively tested and confirmed. This paper reexamines different typical patterns using field tests, implementation surveys from agencies, and mathematical analysis. A model has been developed to determine the optimal patterns. The results reveal that a milled pattern is superior to a rolled pattern for asphalt shoulders in terms of audibility and tactility effectiveness, quality control and ease of construction. The corrugated pattern is practical for concrete shoulders. Evidence is presented that existing implementation of policy and design criteria for rolled rumble strips should be modified and that more research is needed to determine the degree of effectiveness.
