Overview

CEN ISO/TS 24530-2:2006 - tpeg-locML defines the XML encoding of the Location Referencing method used by TPEG (Transport Protocol Experts Group) applications for Traffic and Travel Information (TTI). The specification ensures that TPEG XML messages carry both the location references and event information required by a client TPEG decoder so end-users can be shown where an event occurred. tpeg-locML is designed to be language-independent and machine-readable, enabling map displays and automated map-matching by navigation and TTI clients.

Key topics and technical requirements

• XML encoding of location referencing: Establishes element structures and Document Type Definition (DTD) fragments used to describe locations in tpegML messages (see elements such as location_container, location_coordinates, location_descriptions).
• Language independence: Uses tpeg‑loc tables and external language entity files (word-oriented data object dictionaries) so messages can be rendered in different languages without changing core XML.
• Machine‑readable location data: Enables “thick” clients (e.g., navigation systems) to perform on‑the‑fly map‑matching of events to digital maps.
• Extensible DTD approach: Complete DTD (Annex A) and external entity references (Annex B) are provided for implementation and extension. The DTD approach allows adding alternative location methods (for example, a link-id method) by including or modifying entity references.
• Coordinate and referencing standards: The specification references common enums and tables from the TPEG/SSF series and related ISO technical specifications; abbreviations such as WGS84 and country codes (ISO 3166-1) appear in related normative references.
• Interoperability focus: Designed for multiple bearers and delivery mechanisms (broadcast, internet, DVB/DAB, etc.) to minimize adaptation layers.

Applications and who should use it

• TTI service providers creating standardized message feeds in XML for traffic, travel, and road event data.
• Navigation system vendors and map providers implementing map-matching and event display based on TPEG location references.
• Broadcasters, car manufacturers, and telematics integrators delivering TTI over DAB, DVB, ATSC, ARIB, or IP.
• Software developers and system integrators building TPEG XML decoders, encoders, and middleware that must interoperate across languages and map platforms.

Related standards

• ISO/TS 18234 series (TPEG data-streams, including Location Referencing for applications)
