Jensen, S.S., Plejdrup, M.S., Hillig, K. (2019): GIS-based National Road and Traffic Database 1960-2020. Aarhus University, DCE – Danish Centre for Environment and Energy, 25 pp - Technical Report No. 151. http://dce2.au.dk/pub/TR151.pdf


This report describes the extension and update of the Danish national GIS-based road network and traffic database for 1960-2005 to the years 2005-2020. The original road network has been extended with new motorway sections that have been established since the original road network from 2007. Furthermore, some motorway sections have changed speed limit from 110 to 130 km/t. The development in traffic flow and vehicle mix has been analysed based on traffic data from the Danish Road Directorate to estimate the trend for different road types from 1995 to 2020 as 1995 is the baseline year of the original road and traffic database. This report also includes a description of the road network, all attributes and trends in traffic flow and vehicle mix for the entire period 1960-2020 to be able to read this report separately from previous documentation of the road and traffic database.
