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 with a view to deciding whether it should be confirmed for
a further three years, revised to become an International Standard, or withdrawn. In the case of a confirmed
ISO/PAS or ISO/TS, it is reviewed again after six years at which time it has to be either transposed into an
International Standard or withdrawn.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 24530-3 was prepared by the European Committee for Standardization (CEN) in collaboration with
Technical Committee ISO/TC 204, Intelligent transport systems, in accordance with the Agreement on
technical cooperation between ISO and CEN (Vienna Agreement).
Throughout the text of this document, read “.this European pre-Standard.” to mean “.this Technical
Specification.”.

Introduction
TPEG in XML (tpegML) provides the solution to diverse requirements for the ultimate delivery of TPEG
applications (potentially simultaneously) via for example ARIB, ATSC, DAB, DVB and the Internet. This will
solve the minimal adaptation layers requirement and without doubling up on message carousels, which are
handled at different layers of the protocol stacks.
The original 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 an end-user’s
equipment.
TPEG binary was initially designed to meet a particular brief, from the EBU’s Broadcast Management
Committee; to develop a new protocol for Traffic and Travel Information, for use in the multimedia
broadcasting environment. TPEG applications were developed with service and transport features, which
enable travel-related messages to be coded, decoded, filtered and understood both by humans (visually
and/or audibly) and by agent systems. This brief was also endorsed by the EBU TTI Broadcast Strategy Team,
who recognized the vital importance of a bearer independent TTI protocol.
The development of TPEG binary technology is excellently matched both technically and economically to DAB
and possibly to internet bearers, where of the order of up to 10 kbits/s is considered acceptable. However
other bearers such as ARIB, ATSC and DVB may be able to offer much higher data rates with economic and
technical utility. Nevertheless these bearers are highly structured (layered) in their ability to handle transparent
data services and they include mechanisms suitable for carousel delivery, which would require a considerably
different TPEG data structure before real transparency could be achieved.
Another potential use of tpegML is provided to Service Providers who would have a standardised message
generation interface, yet be able to develop systems suited to their own requirements. This will enable Service
Providers to exchange pre-edited information regardless of their message generation systems and be
substantially language independent.
tpegML has been developed using the DTD approach, which allows the use of different language entity files to
easily provide a truly language independent service. This approach has the advantage that tpegML files can
be rendered in any language, provided the language entity file is available to the internet browser. This
document provides English language entity files only. For other languages the entity files in this document
only require direct translation.
The development of this ISO/TS 24530 series was undertaken jointly with European Broadcasting Union
B/TPEG Group, which has evolved into the TPEG Forum Standards Task Force. Attention is drawn to the
EBU sponsored TPEG Forum development principles, which require all inputs containing IPR to be declared
during drafting work. No such declarations have been made.

Part 3:
tpeg-rtmML
1 Scope
This document establishes the XML encoding of the method of the Road Traffic Message application.
The TPEG-RTM Application is intended to convey information to road users. The information provided relates
to event and some status information on the road network and on associated infrastructure affecting a road
journey. For example, limited information about abnormal operation of links in the network may be included,
such as ferries, lifting-bridges, etc.
The TPEG-RTM Application has the broad objective to allow the generation of Traffic and Travel Information
(TTI) messages, for delivery to the end-user by one or more bearers. A hierarchical methodology has been
developed to allow the creation of messages from a set of TPEG-RTM tables, which are essentially
word-oriented and cover most needs.
These TPEG-RTM tables (essentially word-oriented data object dictionaries) comprise a wide ranging ability
to describe a TTI event and some status information, introducing new precision in a number of areas such as
“Vehicle types”, “Positional information on the carriageway” and “Diversion routing advice”.
It is vital, for further understanding of this document, to have more than a passing understanding of the
TPEG-RTM binary specification which describes, among other things, in a step-by step approach: Message
Management, Level One Classes and how they are structured, hierarchically to provide a full Road Traffic
Message together with the TPEG Location Referencing system.
