The digital speed map is based on the registration of all speed signposts in the county of North Jutland including approximately 22,000 km of roads. A GPS logger with a special designed keyboard as seen below has been used for this purpose.

The local road authorities updates the speed map via a web application also developed in the project. Road Authorities can insert new speed signs, delete existing ones and they can change speed limits or change the positions of signposts.

The detailed digital speed map covers the county of North Jutland and includes all roads - even minor ones. In other parts of Denmark the speed map covers all speed limits above 90 km/h. On all other roads in the rest of Denmark the OBU will react if the speed exceed 80 km/h. In this way we can prevent speeding on rural roads outside the borders of North Jutland, but we cannot prevent speeding on urban roads, where the normal speed limit is 50 km/h.

Outside Denmark the system will be inactive and the display will be blank, since digital maps with speed limit data are currently not available.
