• 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 The RWIS system consists of several components. The in-field Automatic Road Weather Stations communicates with UDCS via GPRS (radio modem, TCP/IP,...). UDCS acquires the measured data. The data are processed by a quality control system and are stored in the database. The UDCS communicates over GTS with an external model and receives the weather forecast data, which are stored in...

System description The automatic road weather station provides ground-truth data acquired in-field on the road. The data are displayed on the real time displays. The ground measured data are used as input for the fog (ice) forecasting model, improving the results of the model. The automatic weather station consists of several parts • Data-logger • Sensors • Meteorological mast • Accessories Field Sensors wind speed and direction non-intrusive road condition and surface temperature sensor visibility and present weather air temperature and relative humidity The typical set of field sensors...

System description Road Weather System (Road & Weather Data) Weather Forecasting (Nowcasting/Forecasting) Maintenance Decision Support System (MDSS) Low Visibility Wind Alarm Black Ice Mobile Road & Weather Data Real Time Displays Modeling and Forecasting The fog and ice forecasting models provide the local visibility forecast and prediction of the ice frost. Although the fog (ice) model cannot prevent the weather conditions, it provides early warning on possible formation of water fog (ice frost). The models are to be taken as early warning to sharpen attention of the operators. Real-Time...
