  • Abstract:
    The Run-off-the-Road(ROTR)type of accidenthas beena predominantfactor in highway ; fatalities nationwide. This situation has created a major concern and challenge for traffic ; management within transportation departments. Shoulderrumble strips are new traffic control ; devices for interstate and limited access roadway systems, which hold great potential for ; reducing ROTR accidents. Consequently,they have becomea critical and attractive subject for. ; highway safety improvements. ; Although shoulder rumble trips have been recognizedas 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 quantitativelytested 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 audibilityand tactility effectiveness,quality controland ease of construction. The corrugated ; pattern is practical for concrete shoulders. E\:'idenceis presented that existing implementation ; of policy and design criteria for rolled rumble strips shouldbe modifiedand that more research ; is needed to determine the degree of effectiveness. ; This study was sponsoredby the Traffic EngineeringDivisionat the VirginiaDepartment ; of Transportation (VDOT).
