Road surface slipperiness is a key factor in safety of road transport. VTT Technical Research Centre of Finland has developed a method for dynamically determining road slipperiness from data in the controller area network (CAN) bus of the vehicle. Axle rotation speeds and other primary data are continuously analysed to determine slipperiness, specific in place and time. The information can be used to support road maintenance or to provide localized warnings directly to vehicles. The slipperiness detection method presented here holds novelty in its combination of measuring accuracy, high locational and temporal specificity and cost-effectiveness. The method and a proof-of-concept warning system have been tested in heavy vehicles, and further piloting as well as commercialization activities are being pursued. Future research and development plans include developing and testing the method for passenger vehicles.
