• 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.
