Advanced Snowplow Program on the Road

This investigation focuses on implementations to minimize risk in snowplowing. Snowplowing has an inherent level of risk both to the plow driver and to guard rails, signs, etc., in the event of a crash. The California Department of Transportation (Caltrans) began experimentation with a plow equipped with magnetic senors. Roads were also augmented with these sensors in select historically snowy places. Results of the magnetic interfaces were successful; they were able to provide the plow driver with more periphery information based on the position of the plow relative to the road. Further investigations in lateral guidance and collision avoidance are planned.
