Top of PageWhat is Transport Canadas involvement with Intelligent Transportation Systems such as the Road Weather Information System (RWIS)?
Transport Canada is working with Environment Canada, and the provinces and territories to develop a national approach to implementing Road Weather Information System (RWIS) because it reduces the requirement for road salt use. RWIS allows for alternative treatment of roads. The system uses weather and road data from automated weather reporting stations installed along the roadway which has special sensors embedded in and below the road, to assist weather forecasters in predicting icing conditions before they occur. Road maintenance crews can use this information to decide if road treatment is necessary, the best time to treat, what chemicals or mixtures to use, and how much is required. RWIS provides timely road information to weather forecasters and maintenance crews and can play an important role in enhancing safety, efficiency, and sustainability of Canada’s transportation system.
