Intelligent transport systems - Traffic and travel information messages via traffic message coding - Part 3: Location referencing for Radio Data System - Traffic Message Channel (RDS-TMC) using ALERT-C (ISO 14819-3:2021)
This document specifies location referencing rules to address the specific requirements of Traffic Message Channel (TMC) systems, which use abbreviated coding formats to provide traffic and travel information (TTI) messages over mobile bearers (e.g. GMS, DAB) or via exchange protocols like DATEX
II. In particular, the rules address the Radio Data System-Traffic Message Channel (RDS-TMC), a means
of providing digitally-coded TTI to travellers using a silent data channel on FM radio stations, based on the ALERT-C protocol.

Introduction
This document primarily addresses the needs of RDS-TMC ALERT-C messages which are in widespread
worldwide use. The modular approach used here is intended to facilitate future extension of the location
referencing rules to other traffic and travel messaging systems.
This document sets out ways of specifying places and positions in traffic and travel information
messages, including RDS-TMC messages (the Radio Data System-Traffic Message Channel).
It defines the structure and semantics of location tables for Traffic Information Centres (TICs) and
receivers.
a) Traffic and travel messages:
1) Traffic and travel information is created and updated in an originating database, by human
operators or automated systems. Information is transferred to one or more remote systems by
means of messages.
2) In this context, a message is a collection of data which is exchanged to convey information for an
agreed purpose between two or more parties. Traffic and travel messages are digitally-coded
sets of data exchanged by interested parties, which convey information about traffic, travel
and/or transport networks. Digital coding may be alphanumeric, as in EDIFACT, or binary, as in
RDS-TMC.
3) The traffic and travel messages developed in programmes of the European Union are open,
non-proprietary proposals for standards intended to serve the public interest by facilitating
interconnection and interoperability of the relevant information systems.
b) Location referencing.
Location references provide the means of saying where in traffic and travel messages.
The location referencing component of a traffic and travel message enables a service provider to indicate
the physical location of the event being described. The management of TMC location databases requires
on-going maintenance. It is necessary to both manage location database ID allocation for countries
implementing TMC services and to validate new and updated location databases when ground features
change. These activities are led by service providers who also need to ensure that their end-users
are kept up-to-date. The Traveller Information Services Association (www .tisa .org) manages the ID
allocation on a worldwide basis. TISA provides location database validation for service providers who
generally arrange location database updates on a bi-annual cycle. This certification procedure extends
the basic rules mentioned in this standard and also applies a best-practice validation. TISA grants a
stamp of quality to those location tables that pass a set of tests.

1 Scope
This document specifies location referencing rules to address the specific requirements of Traffic
Message Channel (TMC) systems, which use abbreviated coding formats to provide traffic and travel
information (TTI) messages over mobile bearers (e.g. GMS, DAB) or via exchange protocols like DATEX
II. In particular, the rules address the Radio Data System-Traffic Message Channel (RDS-TMC), a means
of providing digitally-coded TTI to travellers using a silent data channel on FM radio stations, based on
the ALERT-C protocol.

4.1 General
Location references used by RDS-TMC are covered by the location referencing rules defined in this
subclause. The ALERT-C coding protocol for RDS-TMC is defined in ISO 14819-1.
ALERT-C supports a digital, silent data broadcast service for motorists, providing information about
many kinds of traffic situations. This includes roadwork, weather and traffic incident information
relating to major national and international roads, regional roads and local or urban roads.
4.2 Location tables
4.2.1 General
Within RDS-TMC, locations are identified and referenced by their location code. A given RDS-TMC
service uses a pre-defined location table, containing the pre-stored details of the locations that can be
referenced in messages from that service.
A location code in such a message refers and serves as a tabular ‘address’ of the pre-stored location
details in the location table used by the service. A real-world location may have more than one location
code within the same location table. However, within a given location table, each location code refers to
one and only one location. A location code has a number in the range 1 to 63 487.
In ALERT-C, a further 2048 numbers shall be reserved for INTER-ROAD (see ISO 14819-1) and other
forms of referencing.
A table may contain a maximum number of 65 536 codes allocated in the following way:
Location code Use
0 reserved
1 - 63,487 free for normal location coding
63,488 - 64,511 for special purposes
64,512 - 65,532 for INTER-ROAD
64,533 - 65,535 special functions
NOTE INTER-ROAD is a coding mechanism within ALERT-C to reference in a specific type of ALERT-C
message (the INTER-ROAD message) a location belonging to a different location table. The INTER-ROAD location
can be a table in the same country as well as a table in another country.

ISO 14819-3:2021(E)
4.2.2 Versions and versioning of location tables
Once a location has been allocated, it cannot easily be re-allocated (in an RDS-TMC/ALERT-C
environment). Therefore, all existing locations and their associated location codes in a given location
table should be regarded as fixed. However, other attributes of a location may, within certain
constraints, sometimes change (e.g. name, positive offset, negative offset).
Within each location table, space (unallocated location codes) shall be left to accommodate future
requirements for additional locations (to deal with new construction and location referencing
requirements not originally foreseen).
Whenever new locations are added to, or removed from, a location table (for example to extend coverage
or to reflect changes to the road network), the resulting table shall be treated as a new version. The
creation and tracking of versions of a location table allows the evolution of a location table to be
understood and supports the successful use of the table and associated TMC service. A new version of
an existing location table shall remain compatible with the previous versions of the same location table
– the changes shall not be such that the location of a TMC message could be wrongly interpreted by a
receiver. For example, location codes which are deleted should not be re-used for a long period. Also,
changing the attributes class and type of a location might cause an incompatible version of the table. It
is part of TISA's location certification process to judge if a table is backwards compatible.
The method for identifying and labelling different versions of a location table is shown in C.3.1.
TISA has established an allocation of location tables to show which are in use or available for use in
each country. The responsible agency in a country may apply for additional location table numbers in
future, to support further applications or more detailed, regional location tables. New tables can also be
issued occasionally to allow for complete updates to existing tables. Such major changes will, however,
be very disruptive for users, as existing receivers will not recognize TMC messages relating to the new
location table unless the same location table is also installed in the receiver. Switches from one location
table to a different one (rather than a new version of the same table) should therefore be avoided as far
as possible, especially in established markets.
4.2.3 Exchanging location tables
For TMC services to work well, the different organizations involved need to be able to understand the
location table number, version and contents. To achieve this, a location table exchange format has been
defined.
This format will be used for the exchange of TMC location tables between the var

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. www.iso.org/directives

Introduction
This document sets out ways of specifying places and positions in traffic and travel information messages,
including RDS-TMC messages (the Radio Data System - Traffic Message Channel).
It defines the structure and semantics of location tables for Traffic Information Centres (TICs) and receivers.
a) Traffic and travel messages;
1) Traffic and travel information is created and updated in an originating database, by human operators
or automated systems. Information is transferred to one or more remote systems by means of
messages.
2) In this context, a message is a collection of data which is exchanged to convey information for an
agreed purpose between two or more parties. Traffic and travel messages are digitally-coded sets of
data exchanged by interested parties, which convey information about traffic, travel and/or transport
networks. Digital coding can be alphanumeric, as in EDIFACT, or binary, as in RDS-TMC.
3) The traffic and travel messages developed in programmes of the European Union are open, non-
proprietary proposals for standards intended to serve the public interest by facilitating interconnection
and interoperability of the relevant information systems.
b) Location referencing.
Location references provide the means of saying where in traffic and travel messages
The location referencing component of a traffic and travel message enables a service provider to indicate the
physical location of the event being described. The management of TMC location databases requires on-
going maintenance. It is necessary to both manage location database ID allocation for countries implementing
TMC services and to validate new and updated location databases when ground features change. These
activities are led by service providers who also need to ensure that their end-users are kept up-to-date. The
Traveller Information Services Association (www.tisa.org) manages the ID allocation on a worldwide basis.
TISA provides location database validation for service providers who generally arrange location database
updates on a bi-annual cycle.

DRAFT INTERNATIONAL STANDARD
ISO/DIS 14819-3:2019(E)
Intelligent transport systems — Traffic and travel information
messages via traffic message coding —
Part 3:
Location referencing for Radio Data System — Traffic Message
Channel (RDS-TMC) using ALERT-C
1 Scope
This standard primarily addresses the needs of RDS-TMC ALERT-C messages which arein widespread
worldwide use , however, the modular approach used here is intended to facilitate future extension of the
location referencing rules to other traffic and travel messaging systems.
The location referencing rules defined in this part of ISO 14819 address the specific requirements of Traffic
Message Channel (TMC) systems, which use abbreviated coding formats to provide TTI messages over
mobile bearers (e.g. GMS, DAB) or via exchange protocols like DATEX and DATEX II. In particular, the rules
address the Radio Data System - Traffic Message Channel (RDS-TMC), a means of providing digitally-coded
traffic and travel information to travellers using a silent data channel (RDS) on FM radio stations, based on the
ALERT-C protocol.
A certification process is set in place within TISA to validate in detail the submitted location tables. This
certification procedure extends the basic rules mentioned in this standard and also applies a best-practice
validation. TISA grants a stamp of quality to those location tables that pass a set of tests.
