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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of normative document:
— an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical
experts in an ISO working group and is accepted for publication if it is approved by more than 50 % of
the members of the parent committee casting a vote;
— an ISO Technical Specification (ISO/TS) represents an agreement between the members of
a technical committee and is accepted for publication if it is approved by 2/3 of the members of the
committee casting a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for
a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or
ISO/TS is confirmed, it is reviewed again after a further three years, at which time it must either be
transformed into an International Standard or be withdrawn.
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.
ISO/TS 18234-1 was prepared by the European Committee for Standardization (CEN) Technical
Committee CEN/TC 278, Road transport and traffic telematics, in collaboration with ISO Technical
Committee ISO/TC 204, Intelligent transport systems, in accordance with the Agreement on technical
cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (18234-1:2006), which has been technically revised.
ISO/TS 18234 consists of the following parts, under the general title Intelligent transport systems — Traffic
and travel information via transport protocol experts group, generation 1 (TPEG1) binary data format:
— Part 1: Introduction, numbering and versions (TPEG1-INV)
— Part 2: Syntax, semantics and framing structure (TPEG1-SSF)

Introduction
TPEG technology uses a byte-oriented data stream format, which may be carried on almost any digital
bearer with an appropriate adaptation layer. TPEG messages are delivered from service providers to end-
users and used to transfer information from the database of a service provider to an end-user’s equipment.
The brief history of TPEG technology development dates back to the European Broadcasting Union
(EBU) Broadcast Management Committee establishing the B/TPEG project group in autumn 1997 with
the mandate 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 are
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.
One year later in December 1998, the B/TPEG group produced its first EBU specifications. Two Technical
Specifications were released. ISO/TS 18234-2 (TPEG-SSF) described the Syntax, Semantics and Framing
Structure, which is used for all TPEG applications. ISO/TS 18234-4 (TPEG-RTM), described the first
application, for Road Traffic Messages.
Subsequently, CEN/TC 278/WG 4, in conjunction with ISO/TC 204, established a project group
comprising the members of B/TPEG and they have continued the work concurrently since March 1999.
Since then two further parts were developed to make the initial complete set of four parts, enabling the
implementation of a consistent service. ISO/TS 18234-3 (TPEG-SNI) describes the Service and Network
Information Application, which should be used by all service implementations to ensure appropriate
referencing from one service source to another. ISO/TS 18234-1 (TPEG-INV), completes the series, by
describing the other parts and their relationship; it also contains the application IDs used within the
other parts. Additionally, ISO/TS 18234-5, the Public Transport Information Application (TPEG-PTI),
was developed.
But a major step forward was to develop 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. The original issue of ISO/TS 18234-6 described the
TPEG-Loc application in detail and was used in association with the other parts of ISO/TS 18234 series
to provide location referencing.
TPEG-Loc was designed to offer service providers and end-users several large and significant advantages
over previous location based services. TPEG-Loc formed the basis of location referencing for any TPEG
application that may be specified. However, as time progressed and new TPEG applications were being
developed, it became clear that two new requirements would need to be satisfied. Firstly, detailed
segment descriptions would be needed for applications such as TPEG-Congestion and Travel Time
where for example dynamic segments and sub-segments are required. Secondly, new requirements for
the use of existing pre-coded location formats such as the Korean Node Link Location and the VICS Link
Location methods and the most recent Dynamic Location Referencing method developed by ISO/TC 204.
The TPEG-Location Referencing Container (TPEG-LRC) is designed remembering the original TPEG
objectives, to ensure that it meets all needs of both service providers and potential client devices. It is thus
flexible in use, from both a service provision and end-user viewpoint. It will be issued as soon as possible.
TPEG applications are now developed using UML modelling and a software tool is used to automatically
select content which then populates a TS. Diagrammatic extracts from the model are used to show the
capability of the binary coding in place of lengthy text descriptions; the diagrams do not necessarily
include all relevant content possible.
This Technical Specification provides an index to the other parts of ISO/TS 18234 and describes the AID
for TPEG (See Clause 4).
During the development of the TPEG technology a number of versions have been documented and various
trials implemented using various versions of the specifications. At the time of the publication of this
Technical Specification, the original parts are fully inter-workable and no specific dependencies exist. Now
