The Danish Civil Aviation and Railway Authority (Danish: Trafikstyrelsen) is the Danish government agency responsible for regulating, planning and safety relating to public transport in Denmark. The agency also acts as an advisor towards the ministry related to policy and strategic development in transport. It further acts as the administrator of the government's procurement of ferry and rail transport through public service obligations and collects and publishes statistics related to public transport.
The agency was reorganised on 14 April 2010.[1] It was from 2010 to 2021 a part of the larger Danish Transport, Construction and Housing Authority (Danish: Trafik-, Bygge- og Boligstyrelsen).
By royal resolution on 23 January 2021, the Ministry of the Interior and Housing was established, and the authority's areas of responsibility for housing and construction were transferred to the newly established Danish Housing and Planning Authority and the authority's name was changed to Danish Civil Aviation and Railway Authority.[2]
