Abstract: The project objective is to develop a system for the registration / verification of road state that with high precision can monitor the condition of the road network in real-time. The project will demonstrate how road state data can be collected and linked with other information such as weather conditions and operational measures in the form of snow clearing and gritting. It will also be shown how road state data can be used to improve the prognosis for the development in the driving conditions. Participating countries are Denmark, Iceland, Norway, Sweden, Finland and Faroe Island.
