Three models are presented: slippery road information system (SRIS), bearing information through vehicle intelligence (BiFi), and support system for winter maintenance (SSWM). The SRIS integrates information from a weather model and car data to give a view of the current condition of the road, and has shown very promising results. During the trial period, 100 cars were connected to deliver online data. The model can be used to give information to different kinds of road users, such as winter maintenance personnel and private drivers, about where there are slippery conditions as well as when it is time to lower speed limits or to perform maintenance activities. The BiFi is a model for detection of quality of the road coating and detection of bearing strength during thaw–freeze periods. The BiFi is used as a tool for judging the load-bearing capacity of the road network in a detailed and dynamic way. Tests have been successful and are a basis for further product implementation. SSWM combines information from sources such as RWIS, salt trucks, and weather forecast models, resulting in a powerful tool for winter road maintenance. The SSWM includes models for calculation of road surface temperature and road conditions, the spatial variation of slipperiness, the severity of a specific weather situation with respect to risk for road slipperiness, and need for maintenance activity.
