ISO/TS 24530-1:2006 PDF

Overview

ISO/TS 24530-1:2006 defines tpegML - an XML representation for Traffic and Travel Information (TTI) based on the Transport Protocol Experts Group (TPEG) framework. The Technical Specification establishes the top-level XML “containers” (document, message set, message) and the common data types used across tpegML applications (for example tpeg-ptiML). tpegML is inherently designed to map the TPEG binary format (ISO/TS 18234 series) while providing additional XML tags to support message and message-set structure for easy internet file delivery and multilingual rendering.

Key topics and technical requirements

• Top-level containers: Definitions for tpeg_document, tpeg_message_set and tpeg_message to structure TTI content for XML delivery.
• Common data types: Standardized elements for times, day masks, integer and numeric formats, short/long strings and other reusable types used by tpegML profiles.
• DTD-based schema: The specification uses Document Type Definitions (DTDs) (Annex A/B) to define element and attribute structure; guidelines and examples are provided to aid implementation.
• Mapping to binary TPEG: tpegML is designed to map to the TPEG binary specifications (ISO/TS 18234 series) ensuring consistency between XML and byte-oriented delivery formats.
• Internationalisation support: Language entity files allow tpegML documents to be rendered in different languages without changing the core DTDs - supporting language independence for service delivery.
• Bearer and delivery considerations: Intended for broadcast and internet delivery scenarios (DAB, DVB, ARIB, ATSC, web), with tags that facilitate internet file delivery and interoperability with carousel mechanisms where needed.
• Normative references: Relies on related standards such as ISO/TS 18234 (TPEG binary), ISO 8601 (date/time), and ISO 3166-1 (country codes).

Applications and who uses it

• Traffic and travel service providers: Standardized message generation interfaces for creating TTI feeds that are consistent across platforms and languages.
• Broadcast operators and digital radio/TV systems (DAB/DVB/ARIB/ATSC): Integrating TTI content for carriage over legacy broadcast bearers or hybrid broadcast-broadband systems.
• ITS software developers and data integrators: Implementing servers/clients that produce or consume TTI in XML and map it to/from TPEG binary.
• Navigation and fleet management vendors: Consuming structured TTI (RTM, PTI, locML) to show incidents, routing advice and public-transport updates in user interfaces or agent systems.
• Localization teams: Using language entity files to publish TTI in multiple languages without reworking core message structures.

Related standards

• ISO/TS 24530-2 (tpeg-locML), 24530-3 (tpeg-rtmML), 24530-4 (tpeg-ptiML)
• ISO/TS 18234 series (TPEG binary data-streams)
• ISO 8601 (date/time formats)
• ISO 3166-1 (country codes)

ISO/TS 24530-1 is practical for organizations that need a standard, interoperable XML format for traffic and travel information, while retaining compatibility with existing TPEG binary ecosystems and supporting web-friendly delivery and localization.
