Overview
ISO/TS 24530-3:2006 / CEN ISO/TS 24530-3 defines the XML encoding (tpeg-rtmML) for the TPEG Road Traffic Message (RTM) application. It specifies how Road Traffic Messages - part of Traffic and Travel Information (TTI) delivered via the Transport Protocol Experts Group (TPEG) - are represented in XML. The Technical Specification covers message structure, example XML, a DTD and external entity references to enable interoperable production, exchange and rendering of road traffic information.
Keywords: TPEG, TTI, tpeg-rtmML, XML encoding, Road Traffic Message, ISO/TS 24530-3:2006.
Key topics
- Scope & purpose: Establishes XML encoding for the TPEG-RTM application to convey events and status information affecting road journeys.
- Message structure: Defines core XML element names such as road_traffic_message and related sub-elements used to describe events and attributes.
- Event categories: Covers common RTM content areas including:
- repetitive_time / non_repetitive_time
- accident, obstructions, activities
- road_conditions, network_performance, network_conditions
- facilities_performance, moving_hazards, security_alert
- public_transport_info, visibility, weather, diversion_advice
- Validation artifacts: Includes a normative DTD (tpeg-rtmML.dtd) and external entity references (tpeg-rtmML.ent) for schema/DTD-based validation.
- Examples & guidance: Provides example XML and tables to illustrate encoding patterns and common data types.
- Interdependence: Requires familiarity with binary TPEG RTM concepts and TPEG location referencing for full implementation.
Applications
- Generating standardized Road Traffic Messages for broadcasting, internet feeds and in-vehicle systems.
- Enabling multi-bearer delivery (DAB, DVB, ARIB, ATSC, Internet) with a consistent XML message model.
- Exchange of pre-edited, language-independent TTI content between service providers, back-office systems and content aggregators.
- Input to navigation systems, traffic management centers, traveler information portals and mobile apps for routing and traveler advisories.
Keywords: traffic data XML, TPEG XML, road traffic XML, TTI delivery, navigation integration.
Who should use this standard
- Traffic and travel service providers producing TTI feeds
- Broadcast and digital radio system integrators (DAB, DVB, ATSC, ARIB)
- Intelligent Transport Systems (ITS) developers and software vendors
- Navigation & fleet-management solution providers
- Transport authorities and traffic control centers
