Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

expressions related to conformity assessment, as well as information about ISO's adherence to

the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by Technical Committee ISO/TC 204, Intelligent transport systems.

This first edition cancels and replaces the first edition (ISO/TS 21219-1:2016), which has been

technically revised.
The main changes are as follows:

— the document status has been changed from Technical Specification (TS) to International Standard

(IS);

— the content has been updated to reflect new TPEG2 specifications and corresponding Application

Identifications (AID), e.g. TPEG2-VLI, TPEG2-WEA, etc.
A list of all parts in the ISO 21219 series can be found on the ISO website.

ISO 21219-1:2023(E)
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/TS 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 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 synchronised, 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 covering 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 and XML; 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.

ISO 21219-1:2023(E)

TPEG2 has a three-container conceptual structure: message management (ISO 21219-6), application

(several parts) and location referencing (ISO/TS 21219-7). This structure has flexible capability and

can accommodate 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 is potentially 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/TS 21219-7).
1) 2)

— 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/TS 21219-21), TPEG2-TLR

(ISO 17572-2), TPEG2-DLR (ISO 17572-3).
3) 4) 5)

— Applications: TPEG2-PKI (ISO 21219-14 ), TPEG2-TEC (ISO 21219-15 ), TPEG2-FPI (ISO 21219-16 ),

TPEG2-TFP (ISO 21219-18), TPEG2-WEA (ISO 21219-19 ), TPEG2-RMR (ISO/TS 21219-23), TPEG2-

EMI (ISO/TS 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.
