LOW-COST SHOULDER RUMBLE STRIPS REDUCE ACCIDENT RATE 52%

The article discusses a new variation on rumble strips developed by the California Department of Transportation (Caltrans). What distinguishes the Caltrans variation is extensive use of rumble strips along highway shoulders to reduce by over 50% the rate of 'ran-off-road' type accidents, and the Department's development of a cost-effective way to build the strips into continuous miles of pavement. Subjects covered include background to the rumble strip development, testing, asphalt materials, and vibratory roller modifications for building the rumble strips.
