DATEX II is the electronic language used in Europe for the exchange of traffic information and traffic data. The development of DATEX II was initiated in the early 90s because of the need to exchange information between traffic centers of motorway operators. Soon there was the need to open this information to service providers. DATEX I was somewhat too limited for this and used outdated technical concepts. Which is why DATEX II was developed in the early years of this millennium. By means of DATEX II, traffic information and traffic management information is distributed in a way that is not dependent on language and presentation format. This means that there is no room for misunderstandings and / or translation errors by the recipient, but the recipient can choose to include spoken text, an image on a map, or to integrate it in a navigation calculation. The increasing scale on which ITS services are being dimensioned, as well as the new digitization requirements arising from self-driving cars, requires increased use of standards and thus also challenges the DATEX II community accordingly.

  • The stakeholder cooperation maintaining DATEX II is hosted by CEDR (Conference of European Directors of Roads) per the 1st of January 2016. CEDR supports DATEX II because of its strategical significance for national road authorities and road operators. The DATEX II organisation is open to all stakeholders in the traffic and travel domain that want to participate in the development, maintenance and user support of DATEX II.
  • Some activities of the DATEX II organization are funded by EU CEF Programme Support Action (PSA) Agreement number MOVE/C3/SUB/2015-547/CEF/PSA/SI2.733309 RWS.
  • The governance of the DATEX II organization is controlled by the “Rules of Procedure of the DATEX II organization”, which can be found on the bottom of this page. These rules apply to all partners in the DATEX II organization.
  • DATEX II is a multi-part standard, maintained by CEN Technical Committee 278, Road Transport and Traffic Telematics, see www.itsstandards.eu.
  • The first six parts of the CEN DATEX II series CEN/TS 16157 have already been approved as Technical Specifications in 2011-2015. The first three parts and the seventh part of the CEN DATEX II series are under approval as European Standards.
