Information not data: Future development of road weather information systems

摘要

The Swedish Road Weather Information System is a tool for road winter maintenance giving warnings about risk of slipperiness and severe weather conditions. The system is based on OF matological research at the University of Goteborg and was initiated by Professor Sven Lindqvist during the 1970s. Knowledge about micro- and local climate variations is crucial when it comes to forecasting and giving warnings about different kinds of weather-related traffic disturbances. The progress of climatological research has made it possible to increase the use of road weather data into different applications. Future development will be focused upon development of the road weather information system towards a user-friendly maintenance decision support system which will enhance the benefits of the road weather information system.
