Intelligent transport systems - Traffic and travel information via transport protocol experts group, generation 2 (TPEG2) - Part 13: Public transport information service (TPEG2-PTS)

This document describes the “public transport information service” (PTS) application, which is intended to cover all modes of public (i.e. collective) transport, both for inter-urban and intra-urban travel. The PTS application is designed to allow the efficient and language-independent delivery of public transport information directly from a service provider to end-users. The PTS application design is based on three main use cases. - Provision of alert information: an alert is a warning that indicates an emergency situation. This case is specifically relevant for broadcast/push mode, for major deviations or disruptions which are relevant for a large number of travellers. A dedicated alert request is also defined and can be used if a backchannel is available. - Timetable information, both scheduled and real time: this information is in some cases relevant for broadcast, e.g. in case of large events for the transport modalities to/from the event site. A dedicated timetable request is also defined and can be used if a backchannel is available. - Individual requests for trip information (backchannel is required). The PTS application focuses on providing core information regarding public transport in order to ensure the compactness of the TPEG application. Specific information as provided in typical public transport apps (e.g. fare information) is not in the scope of this document.

Overview

ISO/TS 21219-13:2025 - Intelligent transport systems - Traffic and travel information via transport protocol experts group, generation 2 (TPEG2) - Part 13: Public transport information service (TPEG2-PTS) defines a compact, language‑independent application profile for delivering public (collective) transport information for both inter‑urban and intra‑urban travel. The technical specification targets efficient delivery from service providers to end‑users using TPEG2 over broadcast (push) and backchannel (request/response) modes.

Key topics and technical requirements

• Primary use cases
  • Alert information: emergency and major disruption warnings suitable for broadcast; optional alert requests via backchannel.
  • Timetable information: scheduled and real‑time timetable distribution; supports broadcast for large events and on‑demand timetable requests.
  • Individual trip requests: personalized trip information (requires backchannel).
• Message model and components
  • Defines PTS message components (e.g., PTSMessage, GeoLocation, PtRequest, Alert, TripInfoResponse) and ordered component handling to ensure interoperability.
• Data types and reference tables
  • Standardized datatypes (StopPlace, StopPoint, Route, TimeInfo, TripLegStructure, etc.) and lookup tables (mode/submode of transport, service types, alert causes/events) for consistent semantics.
• Representation formats
  • Normative support for binary TPEG representation and tpegML (XML-like) representations to fit different transmission and processing environments.
• Operational constraints
  • Application identification, version signalling, extendibility rules, and TPEG service component framing to guarantee compactness and forward compatibility.
• Scope exclusions
  • Focuses on core public transport information; detailed commercial or fare information (typical in consumer apps) is explicitly out of scope.

Applications and who uses it

• Public transport operators and agencies: distribute network alerts, realtime timetable updates, station/stop information.
• ITS integrators and mobility platform providers: ingest standardized PTS messages to power trip planning, multimodal routing, and disruption management.
• Broadcasters and connectivity providers: carry TPEG2-PTS in broadcast streams or hybrid broadcast/broadband services.
• App developers and in-vehicle systems: present compact, language‑independent transport data for passengers and drivers.
• Traffic management and emergency services: rapidly disseminate large-scale disruption and safety alerts.

Related standards

• Part of the ISO 21219 series and developed under ISO/TC 204 (Intelligent transport systems). Integrates with other TPEG2 application profiles and conforms to TPEG binary and tpegML representations.

Introduction
0.1  History
TPEG technology was originally proposed by the European Broadcasting Union (EBU) Broadcast
Management Committee, who established the B/TPEG project group in the autumn of 1997 with a brief to
develop, as soon as possible, a new protocol for broadcasting traffic and travel-related information in the
multimedia environment. TPEG technology, its applications and service features were designed to enable
travel-related messages to be coded, decoded, filtered and understood by humans (visually and/or audibly
in the user’s language) and by agent systems. Originally, a byte-oriented data stream format, which can be
carried on almost any digital bearer with an appropriate adaptation layer, was developed. Hierarchically
structured TPEG messages from service providers to end-users were designed to transfer information from
the service provider database to an end-user’s equipment.
One year later, in December 1998, the B/TPEG group produced its first EBU specifications. Two documents
were released. Part 2 (TPEG-SSF, which became ISO/TS 18234-2) described the syntax, semantics and
framing structure, which was used for all TPEG applications. Meanwhile, Part 4 (TPEG-RTM, which became
ISO/TS 18234-4) described the first application for road traffic messages.
Subsequently, in March 1999, CEN/TC 278, in conjunction with ISO/TC 204, established a group comprising
members of the former EBU B/TPEG and this working group continued development work. Further parts
were developed to make the initial set of four parts, enabling the implementation of a consistent service.
Part 3 (TPEG-SNI, ISO/TS 18234-3) described the service and network information (SNI) application used
by all service implementations to ensure appropriate referencing from one service source to another.
Part 1 (TPEG-INV, ISO/TS 18234-1) completed the series by describing the other parts and their relationship.
It also contained the application IDs used within the other parts. Additionally, Part 5, the public transport
information application (TPEG-PTI, ISO/TS 18234-5), was developed. The so-called TPEG-LOC location
referencing method, which enabled both map-based TPEG-decoders and non-map-based ones to deliver
either map-based location referencing or human readable text information, was issued as ISO/TS 18234-6
to be used in association with the other applications of parts of the ISO 18234 series to provide location
referencing.
The ISO 18234 series has become known as TPEG Generation 1.
0.2  TPEG Generation 2
When the Traveller Information Services Association (TISA), derived from former forums, was inaugurated
in December 2007, TPEG development was taken over by TISA and continued in the TPEG applications
working group.
It was about this time that the (then) new Unified Modelling Language (UML) was seen as having major
advantages for the development of new TPEG applications in communities who would not necessarily have
the binary physical format skills required to extend the original TPEG TS work. It was also realized that the
XML format for TPEG described within the ISO 24530 series (now superseded) had a greater significance
than previously foreseen, especially in the content-generation segment, and that keeping two physical
formats sychronized, in different standards series, would be rather difficult.
As a result, TISA set about the development of a new TPEG structure that would be UML-based. This has
subsequently become known as TPEG Generation 2.
TPEG2 is embodied in the ISO 21219 series and it comprises many parts that cover the introduction, rules,
toolkit and application components. TPEG2 is built around UML modelling and has a core of rules that
contain the modelling strategy covered in ISO 21219-2, ISO 21219-3 and ISO 21219-4 and the conversion to
two current physical formats: binary (Annex A) and XML (Annex B); others can be added in the future. TISA
uses an automated tool to convert from the agreed UML model XMI file directly into an MS Word document
file that forms the annex for each physical format.
TPEG2 has a three-container conceptual structure: message management (ISO 21219-6), application (several
parts) and location referencing (ISO 21219-7). This structure has flexible capability and can accommodate

vi
many differing use cases that have been proposed within the TTI sector and more broadly for hierarchical
message content.
TPEG2 also has many location referencing options as required by the service provider community, any of
which may be delivered by vectoring data included in the location referencing container.
The following classification provides a helpful grouping of the different TPEG2 parts according to their
intended purpose. Note that the list below may be incomplete, as it is possible that new TPEG2 parts will be
introduced after the publication of this document.
— Toolkit parts: TPEG2-INV (ISO 21219-1), TPEG2-UML (ISO 21219-2), TPEG2-UBCR (ISO 21219-3), TPEG2-
UXCR (ISO 21219-4), TPEG2-SFW (ISO 21219-5), TPEG2-MMC (ISO 21219-6), TPEG2-LRC (ISO 21219-7).
— Special applications: TPEG2-SNI (ISO 21219-9), TPEG2-CAI (ISO 21219-10), TPEG2-LTE (ISO/TS 21219-24).
— Location referencing: TPEG2-OLR (ISO/TS 21219-22), TPEG2-GLR (ISO 21219-21), TPEG2-TLR
(ISO 17572-2), TPEG2-DLR (ISO 17572-3).
— Applications: TPEG2-PTS (ISO 21219-13 – this document), TPEG2-PKI (ISO 21219-14), TPEG2-TEC
(ISO 21219-15), TPEG2-FPI (ISO 21219-16), TPEG2-SPI (ISO 21219-17), TPEG2-TFP (ISO 21219-18),
TPEG2-WEA (ISO 21219-19), TPEG2-RMR (ISO/TS 21219-23), TPEG2-EMI (ISO 21219-25), TPEG2-VLI
(ISO/TS 21219-26).
TPEG2 has been developed to be broadly (but not totally) backward compatible with TPEG1 to assist in
transitions from earlier implementations, while not hindering the TPEG2 innovative approach and being
able to support many new features, such as dealing with applications with both long-term, unchanging
content and highly dynamic content, such as parking information.

Technical Specification ISO/TS 21219-13:2025(en)
Intelligent transport systems — Traffic and travel information
via transport protocol experts group, generation 2 (TPEG2) —
Part 13:
Public transport information service (TPEG2-PTS)
1 Scope
This document describes the “public transport information service” (PTS) application, which is intended
to cover all modes of public (i.e. collective) transport, both for inter-urban and intra-urban travel. The
PTS application is designed to allow the efficient and language-independent delivery of public transport
information directly from a service provider to end-users.
The PTS application design is based on three main use cases.
— Provision of alert information: an alert is a warning that indicates an emergency situation. This case is
specifically relevant for broadcast/push mode, for major deviations or disruptions which are relevant
for a large number of travellers. A dedicated alert request is also defined and can be used if a backchannel
is available.
— Timetable information, both scheduled and real time: this information is in some cases relevant for
broadcast, e.g. in case of large events for the transport modalities to/from the event site. A dedicated
timetable request is also defined and can be used if a backchannel is available.
— Individual requests for trip information (backchannel is required).
The PTS application focuses on providing core information regarding public transport in order to ensure the
compactness of the TPEG application. Specific information as provided in typical public transport apps (e.g.
fare information) is not in the scope of this document.

5 Application specific constraints
5.1 Application identification
The word “application” is used in the TPEG specifications to describe specific subsets of the TPEG structure.
An application defines a limited vocabulary for a certain type of messages, e.g. parking information or road
traffic information. Each TPEG application is assigned a unique number, called the AID. An AID is defined in
ISO 21219-1 whenever a new application is developed.
[3]
The AID number is used within the TPEG2-SNI application to indicate how to process TPEG content. It also
facilitates the routing of information to the appropriate application decoder.
5.2 Version number signalling
Version numbering is used to track the separate versions of an application through its development and
deployment. The differences between these versions could have an impact on client devices.
The version numbering principle is defined in ISO 21219-1.
Table 1 shows the current version numbers for signalling PTS within the SNI application.
Table 1 — Current version numbers for signalling of PTS
Major version number 1
Minor version number 0
5.3 Ordered components
TPEG2-PTS requires a fixed order of TPEG components. The order for the PTS message component is shown
in Figure 1; the first component shall be the Message Management Container (MMC). This shall be the only
component if the message is a cancellation message. Otherwise, the MMC component shall be followed by the
one or more Application Data Container component(s) which includes the application-specific information.

Figure 1 — Composition of TPEG messages
5.4 Extendibility
The requirement of a fixed component order does not affect the extension of TPEG2-PTS. Future application
extensions may insert new components or may replace existing components by new ones without losing
backward compatibility, i.e. a TPEG2-PTS decoder shall be able to detect and skip unknown components.
5.5 TPEG Service Component Frame
TPEG2-PTS shall make use of the "Service Component Frame with dataCRC and messageCount" according to
ISO 21219-5.
6 PTS Structure
The structure of a PTS message is shown in Figure 2. This structure conforms to the UML modelling
rules defined in ISO 21219-2. The binary format and XML format of the TPEG2-PTS application for use in
transmission shall be in accordance with Annexes A and B, respectively. Examples of TPEG2-PTS use cases
are shown in Annex C.
Figure 2 — PTS message structure
The structure of the TripLegStructure is shown in Figure 3.
