ROAD CONDITION AND WEATHER INFORMATION SYSTEMS, Federal states of Hesse and Thuringia, Germany

, 2010 / 2008

Challenge

Keeping the roads free of snow and ice and thus ensuring the safety of the road users is a great challenge for the winter services. By means of road condition and weather information systems, the assignment of the winter service can be coordinated in a target-oriented and proactive way, so that the necessary measures can be initiated at the right time and at the right place.

Details

Measurement stations collect a variety of measurement values such as road surface temperature, residual salt, precipitation.

The collected data is automatically forwarded to the German National Meteorological Service (Deutscher Wetterdienst).This data is then edited and combined with general weather data. Thus, several times a day reliable road weather forecasts are generated.

At the computer centre, the measurement values, data and weather information are then merged. The resulting temporally and locally differentiated information on weather and road conditions are evaluated and visualised in a graphical user interface. They are basis for an optimised winter road service adapted to the current weather situation.
