Trafikverket

Trafikverket, also known as the Sweden Transport Administration, is the government agency responsible for the state‑owned road and rail infrastructure in Sweden. It oversees the planning, construction, operation and maintenance of national highways, railways and associated facilities such as bridges, tunnels and traffic control systems. The agency also issues permits for the use of transport infrastructure, manages the allocation of track capacity for railway operators and coordinates winter maintenance to keep routes usable during severe weather. Its services support both passenger and freight transport, enabling the movement of people and goods across the country and across borders. In addition, Trafikverket provides travel information to the public through variable message signs, websites and mobile applications, helping road users make informed decisions.

As a subordinate authority of the Ministry of Enterprise and Innovation, Trafikverket translates national transport policy into concrete actions and long‑term infrastructure plans. It conducts environmental impact assessments for new projects, promotes sustainable transport solutions and works to reduce emissions from the transport sector. The agency operates the national traffic information system, supplying real‑time data to road users and public transport operators. It also engages in research and development activities, testing new technologies such as intelligent transport systems. Trafikverket participates in international transport forums and collaborates with neighbouring countries on cross‑border infrastructure projects. In October 2017 it experienced a distributed denial‑of‑service attack that disrupted train services, email and public websites, highlighting the importance of protecting its critical IT systems.

Trafikverket is wholly owned by the Swedish state and has no private shareholders or parent company; its budget and strategic direction are set by the Swedish parliament and government. The organisation employs civil servants and technical specialists who work across regional offices throughout Sweden to ensure local knowledge is integrated into national projects. Its mandate includes maintaining the reliability and safety of the transport network while adapting to evolving societal needs and technological developments. The agency reports regularly to the Riksdag on progress toward national transport goals and publishes annual accounts that detail expenditures and performance indicators.
