When the emergency rooms registers an accident, it is based on the Road Directorate's model for what information must be obtained about the accident. Among other things, whether the accident happened in daylight or twilight is recorded. Also, whether the road surface was smooth or dry, and whether the accident occurred at an intersection or a roundabout. In this way, the police, the municipalities and the Road Directorate get a detailed and uniform knowledge of the individual accidents.
The police also use the Road Directorate's model when they register accidents. This makes it possible for data to be analysed across police information from reported accidents and the new data from the emergency rooms.
