Abstract
For transmitting early warning signals of slick road conditions (1, 2, 3, 4), in addition to automatic measuring stations (AMS1-AMS5) that have probes for the weather conditions and the freezing point of liquid present on the road, virtual stations (VS1-VS 11) are created and used for which weather data, freezing point data, and parameters are taken from the automatic measuring stations in order to transmit an early warning of slick conditions for the virtual stations also, by means of an evaluating device (5).
