Most actions in winter maintenance are triggered by weather events. Weather forecasts are a very important source of Information for decision maker in winter service but they are not the only one. Together with information about road weather, road state and traffic winter service operates. New technologies in data collection, transfer and analysis enable new innovative technologies to support decision makers. Road weather information systems deliver valuable input about the current situation on the road network. Sensors get more complex and combine different values into a system. Stationary mounted sensors only give data on a very small area therefore it is critical where they are mounted.
