For more than a decade the Road Authorities and the Meteorological Institute have had a close corporation developing the meteorological information supplied to the supervisors responsible for the winter road maintenance in Denmark. In the fall of 1995 it was decided to develop a new presentation system requiring that it should be an open system implying among other things that new sensors or road stations provided by different manufactures should easily be included. At the same time the system should support the existing more than 200 road stations.
Apart from the observations from the road stations the system presents forecasts for the individual road stations as well as counties based on the Danish Road Condition Model, general forecasts, radar data and additional meteorological observations. A first version of the system was tested during the 96/97 season and since the 97/98 season the system has been used operationally by all county and national road authorities living up to its goal of openness as already during the first operational season two foreign vendors supplied road stations to the system consisting now of nearly 250 stations.
