CEN ISO/TS 24530-3:2006 PDF

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

Related standards

• ISO/TS 24530-1 - Introduction, common data types and tpegML
• ISO/TS 24530-2 - tpeg-locML (location encoding)
• ISO/TS 18234-1, -2, -4, -6 - TPEG data-stream syntax/semantics and RTM binary/location referencing

Using ISO/TS 24530-3:2006 (tpeg-rtmML) helps ensure interoperable, validated XML representations of road traffic messages for reliable multi-bearer distribution and downstream integration into ITS and navigation services.
