This Technical Specification (CEN/TS) was approved by CEN on 28 September 2004 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.

CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania,
Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

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 18234-4 was prepared by Technical Committee ISO/TC 204, Intelligent transport systems.
ISO/TS 18234 consists of the following parts, under the general title Traffic and Travel Information (TTI) — TTI
via Transport Protocol Expert Group (TPEG) data-streams:
⎯ Part 1: Introduction, numbering and versions
⎯ Part 2: Syntax, Semantics and Framing Structure (SSF)
⎯ Part 3: Service and Network Information (SNI) application
⎯ Part 4: Road Traffic Message (RTM) application
⎯ Part 5: Public Transport Information (PTI) application
⎯ Part 6: Location referencing applications

Introduction
TPEG technology uses a byte-oriented 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 are
used to transfer application data from the database of a service provider to a user’s equipment.
This document describes the Road Traffic Message application in detail.
It should be remembered that the TPEG-RTM has been derived from earlier work that resulted in the
RDS-TMC standards (EN ISO 14819-2). Upon analysis, RDS-TMC can be seen to drift into other application
areas, where it covers a few public transport, parking and weather messages. TPEG-RTM is just one of
several applications required to provide a fully comprehensive traffic and travel information service, for
example a service is likely to need public transport information, parking information and weather information –
these are or will be the subject of other TPEG-application specifications.
Nevertheless, TPEG-RTM, where reasonable, has included the ability
