Automated snow avalanche hazard reduction

Increased travel demand on the winter/alpine roads of the Western USA has resulted in a dramatic increase in the hazard to motorist and maintenance section personnel from snow avalanches. These encounters often have disastrous consequences. Presented here are preliminary results from testing of an integrated technology to manage the avalanche hazard to motorists and maintenance section personnel using an automated system. Such systems for automated avalanche hazard management are an alternative to the extremely costly installation of permanent avalanche defense structures (avalanche sheds & snow fences), which are commonly found in Europe and Japan. In addition, this system will augment the existing methods of operation on many North American roadways where avalanche forecasting and explosives control is practiced. The specific tasks associated with testing this technology include: integration of sensors, data logging and communication, and automated data processing leading to actuation of road closure gates and notification; including roadside message boards, and maintenance and emergency agencies.
