THE PREDICTION OF ICE ON ROADS USING FUZZY LOGIC

The goal to minimise the risk of icy roads can only be accomplished by looking into the future. It is obviously not enough to rely on an ice sensor which only reflects the current state of the road. To give road maintenance a fair chance to take countermeasures there must be an alert at least three hours in advance. This can be done by using a model that takes all influences on the road surface temperature into consideration. Moreover, it is necessary to be informed of the state of the road, whether it is/will be dry or wet. A computer model has been developed which is able to forecast the road temperature up to six hours in advance using local measurements only. The typical accuracy for a three-hour prediction during a whole winter season is better than 0.75 degrees and is lower still during night-time. (A) For the covering abstract see IRRD 882109.
