A new technology developed by the VTT Technical Research Centre of Finland provides drivers with warnings of black ice on the roads. This automatic detection system will warn a driver in advance that a road is dangerous due to the presence of ice. According to VTT, this uses a novel, real-time method of obtaining information on road surface friction and employs data collected from the car’s in-built sensors. This compares the speeds of the drive shafts and axles in an array of driving conditions, with an al
