2. Best Practices in Monitoring Deployment 2007Road Weather Monitoring2 Road monitoring in Spain Definition of service levels (used in driver information) with regard to weather and road surface condition (five illustrated with different colours) utilising also information from drivers’ speed behaviour

3. Best Practices in Monitoring Deployment 2007Road Weather Monitoring3 Road segment forecasting Continuous forecasting of road surface condition (road temperature) on the basis of interpolation of point forecasts and road condition model based on real-time road weather station data Validation by thermal mapping (monitoring of road temperature) with the help of infrared sensors in spreaders Use in automatic spreader control including, in the future, automation of dosage control Quality of forecast: mean deviation and mean absolute deviation

4. Best Practices in Monitoring Deployment 2007Road Weather Monitoring4 Friction monitoring utilising vehicle sensors Inexpensive software solution based on fusion of data from vehicle sensors (ABS, STC/ESC, Outdoor temperature, air pressure, fog light on/off, …) Passing information on to the road weather stations along route Combination of information from several cars and exclusion of “outliers” Need for a generic communication platform http://trisstest.vv.se/mip/client/GenericIMS/GIMSGUI.aspx
