Multi-part standard
Several new requirements have emerged during the lifecycle of version 3 that require additional modeling and integration into the existing standard. DATEX II is currently revising several parts of the standard, with a specific focus on:
Part 2: Location Referencing This part of the CEN – EN 16157 series specifies the informational structures, relationships, roles, attributes and associated data types, for the implementation of the location referencing systems used in association with the different publications defined in the DATEX II framework. It also defines a DATEX II publication for exchanging predefined locations. This is part of the DATEX II platform independent data model.
Part 3: Situation Publication Part 3 of CEN – EN 16157 will specify informational structures, relationships, roles, attributes and associated data types required for publishing road traffic situation information. This is specified as a DATEX II sub-model which is part of the DATEX II platform independent model, but this Part only covers those elements that are defining road traffic situations. It excludes those elements that relate to location information or common elements which are specified in part 2 and part 7 of CEN – EN 16157.
Part 7: Common Data Elements Part 7 of CEN – EN 16157 specifies and defines component facets required to support the exchange and shared use of data and information in the field of traffic and travel. The component facets include the framework and context for data content, data structure and relationships, communications specification. The document is applicable to: traffic and travel information which is of relevance to road networks (non-urban and urban), public transport information that is of direct relevance to the use of a road network (e.g. road link via train or ferry service), traffic and travel information in the case of Cooperative intelligent transport systems (C-ITS).
