RSI - Road Status Information A new method for detection of road conditions

ITS – intelligent transport solutions are important in today’s society with demand on safe and environmental friendly driving. With the new RSI technology (Road Status Information), it is possible to optimize road maintenance by offering accurate and comprehensive information to contractors and other user groups about road conditions along the entire road network. Using the information available within modern cars combined with models and data from RWIS – road weather information systems makes it possible to find solutions for detection of different kinds of road maintenance needs within areas such as:  Winter Road Conditions  Bearing Strength  Pavement Quality  Air Pollution FCD (floating car data) from vehicles and road weather information from RWIS together with road weather prediction models makes it possible to determine the road conditions with regards to slipperiness and friction in between the field stations. Another use is to model and forecast the road status according to bearing strength during thaw freezing periods in a detailed and dynamic way. The availability of car data increases the spatial and temporal resolution of the road condition models and it also makes it possible to detect how the car behaves and react not only on weather related surface conditions. By having access to vehicle based data it is also possible to detect such features such as pavement quality along the roads as well as the ambient air quality.
