IMS4 Road Weather Information System is a unique system consisting of several meteorological stations strategically located alongside the highway that offer detailed information about weather and road conditions.
Specialized equipment and computer programs monitor weather and pavement parameters to make forecasts.
This gives the road maintenance authorities opportunities to utilize alternate de-icing chemicals, make optimal use of materials and staff, and practice anti-icing techniques.
RWIS stations are located in strategic locations to provide accurate real-time road weather information and critical observations for forecasts.
