Variation in road slipperiness and friction are closely linked and has a very pronounced effect on traffic safety and accessibility. The present project aims at combining data from RWIS and friction values from floating cars in order to improve the information to drivers and road maintenance personal about the prevailing road conditions. A model will be used where the weather data and the estimated friction values from the cars are interpreted into a high quality output suitable as information to road users. How the information is best presented is also analysed.
