About us

The essence of NDW is that all available traffic data is concentrated in one place. Road authorities throughout the entire country and external data providers (private parties) provide NDW with real-time traffic and status information. NDW collects this data, processes it and makes it available to road authorities and traffic information providers. NDW's data is also available as open data, meaning that it is available to third parties for reuse in their applications.

Participating governments

National government (Rijkswaterstaat), and provincial, city and municipal authorities are all involved in NDW. In 2007, a total of 15 authorities were involved in the initiative to found NDW. Nowadays the alliance counts 19 partners and has reached national coverage.

Board of Supervisors

The Board of Supervisors oversees the collaboration. The participating authorities are represented on this Board by members from: 

  • Rijkswaterstaat
  • Provincial road authorities
  • Municipal road authorities
  • (City) Regions

Implementing body

Correctly processing this vast amount of traffic data and making it available is no simple matter. On behalf of the road authorities NDWs'  implementing body facilitates the partners by assuming these responsibilities for them.

Doing business with NDW

NDW is an alliance of several public authorities and is overseen by a Board of Supervisors in which all these authorities are being represented. Legally, NDW is part of Rijkswaterstaat and therefore also part of the public entity 'Staat der Nederlanden'.


NDW procures according to the appropriate rules of the National Government. NDW uses purchase agreements of the National Government, the Ministry of Infrastructure and the Environment and/or Rijkswaterstaat, where it deems appropriate. NDW devotes itself on behalf of the State of The Netherlands as a purchasing center for the benefit of all participating public bodies. European Tenders of NDW will be published on the announcement platform TenderNed.
