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further three years, revised to become an International Standard, or withdrawn.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International Standard or be withdrawn.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 18234-6 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

Introduction
The 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 information from the database of a service provider to an end-user’s equipment.
The TPEG-Loc methodology has been developed to provide a unified location referencing system for all
TPEG applications that require such referencing systems. This CEN ISO Technical Specification describes
the TPEG-Loc application in detail.
TPEG-Loc is designed to offer service providers and end-users several large and significant advantages over
previous location based services. TPEG-Loc forms the basis of location referencing for any TPEG application
that may be specified.
It is very important to remember the original TPEG objectives, which ensure that the TPEG-Loc is designed to
meet all needs. It is flexible in use, from both a service provision and end-user viewpoint. TPEG-Loc offers
choices for service providers to provide simple single-application services through to multi-application services
using the same location referencing method. TPEG-Loc offers filtering choices for end-users to provide wide
or narrowly focussed information, both urban and inter-urban and for single or multi-modal journeys. TPEG-
Loc provides for both large networked service providers and small single area service providers and allows a
full range of end-user products to be developed, from thick clients such as navigation systems to thin clients
such as small hand held travel assistants.
The Broadcast Management Committee of the European Broadcast Union (EBU) established 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. The 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 public specifications. Two documents
were released. Part 2 (TPEG-SSF, CEN ISO/TS 18234-2) described the Syntax, Semantics and Framing
structure, which will be used for all TPEG applications. Part 4 (TPEG-RTM, CEN ISO/TS 18234-4) described
the first application, for Road Traffic Messages.
CEN /C 278/WG 4, in conjunction with ISO/TC 204/WG 10, 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 have been developed to make the initial complete set of four parts, enabling the implementation of a
consistent service. Part 3 (TPEG-SNI, CEN ISO/TS 18234-3) describes the Service and Network Information
Application, which is likely to be used by all service implementations to ensure appropriate referencing from
one service source to another. Part 1 (TPEG-INV, CEN ISO/TS 18234-1), completes the work, by describing
the other parts and their relationship; it also contains the application IDs used within the other parts.
In April 2000, the B/TPEG group released revised Parts 1 to 4, all four parts having been reviewed and
updated in the light of initial implementation results. Thus a consistent suite of specifications, ready for wide
scale implementation, was submitted to the CEN/ISO commenting process.
In November 2001, after extensive response to the comments received and from many internally suggested
improvements, all four parts were completed for the next stage: the Parallel Formal Vote in CEN and ISO. But
a major step forward has been to develop the so-called TPEG-Loc location referencing method, which
enables both map-based TPEG-decoders and non map-based ones to deliver either map-based location
referencing or human readable information. Part 6 (TPEG-Loc, CEN ISO/TS 18234-6, this document) is now a
separate specification and is used in association with the other parts of CEN ISO/TS 18234 to provide
comprehensive location referencing. Additionally Part 5, the Public Transport Information Application (TPEG-
PTI, CEN ISO/TS 18234-5), has been developed and been through the commenting process.
This Technical Specification, CEN ISO/TS 18234-6, describes the data structure, the encoding and decoding
of “TPEG-Loc”. This document has been prepared by CEN/TC 278 Road Transport and Traffic Telematics in
co-operation with ISO/TC 204, Intelligent Transport Systems.
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, all parts are fully inter-workable and no specific dependencies exist. This Technical
Specification has the technical version number TPEG-Loc_3.0/001.

Part 6:
Location referencing applications
1 Scope
This Technical Specification establishes the method of location referencing used by TPEG applications such
as TPEG-RTM or TPEG-PTI.
TPEG applications are specified to contain all the information required by a client TPEG decoder (i.e. both
location referencing and event information), to present all the information intended for the end-user when it
was originated by the service provider.
The term “application” is used in TPEG specifications to describe specific applications, which are at the
highest layer of the ISO/OSI protocol stack (ISO/IEC 7498-1). Each TPEG application (e.g. TPEG-RTM) is
assigned a unique number that is called the Application IDentification (AID). In this respect TPEG-Loc is not
an application, but it is an essential constituent part of an application.
Location referencing requires a service provider to give an impression or image to the human end-user of
where an event has taken place. This cannot be done easily because the human end-user may or may not be
familiar with the location. TPEG-Loc has the added challenge of attempting to be as language independent as
possible. This is achieved by the use of TPEG-Loc tables (essentially word oriented data object dictionaries).
TPEG-Loc also provides location data in a machine-readable form that allows a “thick” client such as a
navigation system to map-match, on-the-fly, to locate the event being described onto a digital map display.
NOTE Explicit backwards compatibility with the RDS-TMC location referencing method (EN ISO 14819-3) has NOT
been attempted, because RDS-TMC locations are finite in number and must be predetermined. TPEG technology does
not suffer from this restriction.
