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 (see www .iso .org/ directives).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

This document was prepared by Technical Committee ISO/TC 204, Intelligent transport systems, in

collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC

278, Intelligent transport systems, in accordance with the Agreement on technical cooperation between

ISO and CEN (Vienna Agreement).

This third edition cancels and replaces the second edition (ISO 14819-1:2013), which has been

technically revised. The main changes compared to the previous edition are as follows:

— Additional tuning variants have been added to allow referencing of TMC services using the 64 MHz

to 88 MHz band.

— The method of encrypting an RDS-TMC service, previously separately specified in ISO 14819-6,

has been merged into this document as Clause 8. Consequently, some renumbering of sections has

occurred and encryption-specific terms, definitions and abbreviated terms have been added in

Clause 3.

— In some places the text has been improved and/or rearranged for greater clarity. Several

typographical and grammatical errors have been corrected.
A list of all parts in the ISO 14819 series can be found on the ISO website.

Introduction
0.1 General

Traffic and traveller information (TTI) can be disseminated through a number of services and means of

communication to the end user, including static displays (e.g. variable message signs), broadcast audio

to car radios, broadcast data services to in-vehicle equipment (e.g. installed navigation systems) and to

nomadic device terminals (e.g. portable navigation device).

For all such services, the data to be disseminated and the message structure involved in the various

interfaces require clear definition and standard formats, in order to allow competitive products to

operate with any received data.

This document describes the data specification for TTI messages, together with their network layer and

their service layer, which shall be conveyed by the RDS-TMC feature, specified in the IEC 62106 series.

The TTI information chain, from event to end-user, is quite complex and the Traveller Information

Services Association (TISA) value chain shown in Figure 1 helps to explain the key components.

Figure 1 — Traveller Information Services Association TTI value chain

Several entities (e.g. companies, businesses) take part in one or more activities to complete the activities

shown in the value chain. These are described below for improved understanding:

Service provider: An organization that constructs a data service, by gathering data, processing

data and supplying the data service. A service provider negotiates for the use of the necessary data

bandwidth with a Broadcaster and/or Transmission Operator. A service provider is responsible for the

"quality" of the data to its customers and should provide suitable customer support.

Broadcaster: A traditionally incorporated organization responsible for a continuous strand of audio

programmes and their quality. A broadcaster may also be responsible for the overall co-ordination of

"broadcast transmissions" (often a Broadcaster is the licensee of a national regulator). A Broadcaster

may also be a service provider.

TTI services for travellers, using spoken radio reports and in-vision reports, occupy broadcast air-time

and whilst valuable to some, they are considered less useful by others. Furthermore, only some are

useful for travellers on the move. Due to the widespread adoption of the Radio Data System, in VHF/

FM broadcasting on Band II there is the possibility of transmitting coded TTI

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

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received. www .iso .org/patents

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation on the meaning of ISO specific terms and expressions related to conformity

assessment, as well as information about ISO's adherence to the WTO principles in the Technical

Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information

The committee responsible for this document is ISO/TC 204, Intelligent transport systems.

This third edition cancels and replaces the second edition (ISO 14819-1:2013), which has been

technically revised.
This third edition cancels and replaces all previous versions.

ISO 14819 consists of the following parts, under the general title Intelligent transport systems — Traffic

and travel information messages via traffic message coding:

— Part 1: Coding protocol for Radio Data System — Traffic Message Channel (RDS-TMC) using ALERT-C

— Part 2: Event and information codes for Radio Data System — Traffic Message Channel (RDS-TMC)

using ALERT-C

— Part 3: Location referencing for Radio Data System — Traffic Message Channel (RDS-TMC) using ALERT-C

— Part 6 (to become deprecated): Encryption and conditional access for the Radio Data System — Traffic

Message Channel ALERT C coding
Compared to previous releases, this version includes the following additions:

— Additional tuning variants have been added to allow referencing of TMC services using the 64MHz

to 88 MHz band.

— The method of encrypting an RDS-TMC service, previously separately specified in 14819-6, has

been merged into this specification, as Section 8: consequently, some renumbering of sections has

occurred.

— In places the text has been improved for greater clarity. Several typographical and grammatical

errors have been corrected.

ISO/DIS 14819-1:2019(E)
Introduction

Traffic and traveller information (TTI) may be disseminated through a number of services and means

of communication to the end user, including static displays (e.g. Variable Message Signs), broadcast

audio to car radios, broadcast data services to in-vehicle equipment (e.g. installed navigation system)

and to nomadic device terminals (e.g. portable navigation device).

For all such services, the data to be disseminated and the message structure involved in the various

interfaces require clear definition and standard formats, in order to allow competitive products to

operate with any received data.

This part of ISO 14819 describes the data specification for TTI messages, together with their network

layer and their service layer, which shall be conveyed by the RDS-TMC feature, specified in IEC 62106.

The TTI information chain, from event to end-user is quite complex and the TISA (the Traveller

Information Services Association) value chain shown in Figure 1 helps to understand the key

components:
Figure 1 — The Traveller Information Services Association TTI value chain

Several entities (e.g. companies, businesses) take part in one or more activities to complete the activities

shown in the value chain,. wo, in particular are described, for improved understanding:

Service Provider: An organisation that constructs a data service, by gathering data, processing data

and supplying the data service. A Service Provider then negotiates for the use of the necessary data

bandwidth with a Broadcaster and/or Transmission Operator. A Service Provider is responsible for the

"quality" of the data to his customers and must provide suitable customer support.

Broadcaster: A traditionally incorporated organisation responsible for a continuous strand of audio

programmes and their quality. A broadcaster may also be responsible for overall co-ordination of

"broadcast transmissions" (often a Broadcaster is the licensee of a national regulator). A Broadcaster

may
