Summary:In order to output glazed frost early warning signals in roads (1, 2, 3, 4), automatic measuring stations (AMS1-AMS5) having sensors for weather conditio ns and for the freezing point of liquid on the road and virtual stations (VS1- VS11) are set up and used. Weather data, freezing point data and parameters from the automatic measuring stations for said virtual stations are transmitted with the purpose of outputting a glazed frost early warning, whi ch also includes the virtual stations, by means of an evaluation device (5).</S DOAB>
