The components of the DATEX II suite of standards

/v3.3/_images/DATEXII_components1.png

DATEX II establishes specifications for data exchange between the actors like Traffic Information Centres, Traffic Control/Management Centres, Service Providers and other actors like car park operators. Data exchange using DATEX II includes the following information:

  • The use cases and associated requirements, and features relative to different exchange situations,

  • The different functional exchange profiles,

  • The abstract elements for protocols,

  • The data model for exchange (informational structures, relationships, roles, attributes and associated data types required).

Next to the DATEX II Exchange standard (shown on the bottom of the figure), the DATEX II data model includes various substandards or parts. Part 1 describes the rules of the standard, Part 2 describes the chosen location referencing method and Part 7 describes common information elements. Parts 3 to 6, 8 and 9 describe the data model for the exchange of information about a certain type of information. There are parts currently in development that focus on Energy (charging infrastructure), Management of Electronic Traffic Regulations, Urban Access Vehicle Regulations and Logistics.

More about the Parts can be found in the Mastering DATEX II chapter.
