CEN ISO/TS 24530-4:2006 PDF

Overview

CEN ISO/TS 24530-4:2006 - tpeg-ptiML defines the XML encoding for the TPEG Public Transport Information (PTI) application. Part 4 of the ISO/TS 24530 series, this Technical Specification specifies how public (collective) transport information is represented in TPEG XML (tpegML) to enable efficient, language‑independent delivery of transit data to end users, broadcasters, service operators and other information systems.

Key topics and technical requirements

• XML encoding for PTI: Establishes the DTD‑based XML format (tpeg-ptiML) for expressing public transport data, including normative DTD (Annex A) and external entity references (Annex B).
• Data elements and structure: Covers core elements such as public_transport_information, transport_mode, service_information, message_report_type, additional_information, and cross_reference to model routes, services and incidents.
• Message views: Supports multiple presentation "views" that map data for common consumption patterns:
  • Incident Report View
  • Station/Terminal View
  • Route View
  • Individual Service View
• Language independence: Uses a DTD and external language entity files approach so messages can be rendered in different languages without changing the underlying data structure.
• Interoperability focus: Designed to carry PTI via various bearers (broadcast and internet) and integrate with TPEG binary and other TPEG XML parts for location referencing and common data types.
• Normative references and formats: Relies on related ISO/TS parts (tpegML, tpeg-locML), TPEG data-stream specifications (ISO/TS 18234 series) and international codes/notations like ISO 3166‑1 and ISO 8601 for dates/times.

Applications and who uses it

• Public transport operators and transit agencies: Exchange timetable, disruption and service status information in a standardized XML format.
• Broadcasters and service providers: Deliver PTI content via DAB, DVB, internet and other bearers using a consistent TPEG XML interface.
• ITS developers and integrators: Build client applications, dashboards, journey planners and real‑time displays that consume tpeg-ptiML messages.
• Third‑party platforms and aggregators: Normalize multi-operator feeds into a language‑independent schema for onward distribution.

Related standards

• ISO/TS 24530-1 (tpegML common types)
• ISO/TS 24530-2 (tpeg-locML)
• ISO/TS 24530-3 (tpeg-rtmML)
• ISO/TS 18234 series (TPEG data-streams)
• ISO 3166‑1 (country codes), ISO 8601 (date/time formats)

Using CEN ISO/TS 24530-4:2006 (tpeg-ptiML) helps ensure consistent, interoperable public transport messaging across broadcast and internet platforms, supporting multilingual, real‑time transit information delivery.
