IMS 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.
- Road Weather Stations
- Flexibility - different sensors
- Data Acquisition Solution (UDCS)
- Database and Data Processing
- Fog and Ice Predictions
- Low Visibility Systems
- Real-time displays and early warning
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.
Real-time weather and forecast information:
- Pavement sensors in travel lanes to measure road surface temperature, water film height, freezing temperature, road condition
- Non intrusive sensors to measure surface temperature and road surface conditions
- Meteorological sensors adjacent to the roadway to measure: air temperature, dew point temperature, relative humidity, wind speed and direction, visibility, present weather, precipitation occurrence, precipitation accumulation, air pressure, snow depth
- Cameras that take images of the roadway for snow and ice control as well as for traveler information.
- improves timeliness of maintenance actions
- increases winter maintenance efficiency
- minimizes the traveling public's exposure to hazardous weather related roadway conditions.
