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 (ISO 14819-1:2013)
The ALERT-C protocol is designed to provide mostly event-oriented road end-user information messages. Many "hooks" have been left for future development and a few status-orientated road end-user information messages were included.

1.1 Généralités
Le protocole ALERT-C est conçu pour fournir la plupart des messages d'information du conducteur orientés évènements. Il est prévu de définir ultérieurement de nombreuses extensions de protocole, et de fait, quelques informations de guidage routier orientées état ont été incluses.
1.2 Contenu
La section présentation du protocole ALERT-C spécifie les messages pouvant être présentés à l'utilisateur conformément aux exigences générales fixées ci-dessus. Elle définit la structure et le contenu des messages ainsi que leur présentation à l'utilisateur final.
Les messages RDS-TMC sont indépendants de la langue et peuvent être présentés dans celle qui est choisie par l'utilisateur. Le protocole ALERT-C exploite une liste d'événements normalisée (voir ISO 14819‑2) de messages avec leurs valeurs de code qui inclue aussi les problèmes liés au trafic ou d'ordre météorologique.
ALERT-C définit deux catégories d'informations contenues dans les messages: les éléments de base et les éléments optionnels. En principe, les données de base sont présentes dans tous les messages. Les informations optionnelles peuvent être ajoutées aux messages en cas de nécessité.
Les messages utilisateur RDS-TMC normalisés permettent de délivrer les cinq éléments de base suivants, afin de disposer d'une information radiodiffusée explicite:
1) Description de l'événement, donnant les détails relatifs aux conditions météorologiques ou aux problèmes de trafic (par exemple: embouteillage provoqué par un accident) ainsi que, le cas échéant, leur gravité (par exemple: longueur du bouchon résultant).
2) Localisation, indiquant la zone, la section de route ou le point où est située la source du problème.
3) Direction et étendue, identifiant les zones adjacentes, portions ou points particuliers également touchés par l'incident, ainsi que, le cas échéant, le sens du trafic affecté.
4) Durée, donnant une indication de la durée prévue du problème.
5) Conseil de déviation, indiquant s'il est ou non conseillé aux utilisateurs finaux de rechercher et d'emprunter un itinéraire alternatif.
Des informations optionnelles peuvent être ajoutées à n'importe quel message, au moyen d'un ou plusieurs groupes de données RDS complémentaires. Cet ajout optionnel permet l'obtention d'un plus grand nombre de détails ou le traitement de situations inhabituelles. En principe, il est possible d'ajouter un nombre indéfini de champs complémentaires au message de base, à l'unique réserve que la longueur du message ne dépasse pas cinq groupes RDS.
1.3 Gestion de messages
La section gestion de messages traite des fonctions de gestion des messages du RDS-TMC. Le protocole ALERT-C opère une distinction entre des messages utilisateur et des messages système. Les messages utilisateur sont ceux qui sont potentiellement portés à la connaissance de l'utilisateur final, comme défini à la section présentation. Les messages système ne sont utiles qu'au terminal RDS-TMC, pour les besoins de la gestion de messages.
1.4 Transmission
La couche transmission opère la diffusion des messages par voie hertzienne. Le protocole ALERT-C, utilisé en RDS-TMC, reprend l'approche fondamentale d'un travail précédent, dont le but était de coder la plupart des messages avec un seul groupe RDS.
L'information RDS-TMC comprend à la fois des messages système et des messages utilisateur. L'information système se rapporte au service TMC en particulier, et détaille les paramètres dont le terminal a besoin pour t

SIST EN ISO 14819-1:2014
ISO 14819-1:2013(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 (Second
edition - 2009).
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
A number of entities (e.g. companies, businesses) take part in one or more activities to complete the activities
shown in the value chain. Two, 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 content 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 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 messages digitally and "silently" using the RDS-
TMC feature, which avoids the interruption of planned programmes. This TTI delivery method has a number of
advantages: TTI messages can be decoded into the language of the end user, regardless of location, more
messages can be made available and planned broadcast programme interruption is avoided, so make
delivery of TTI messages more timely and topical.
The ALERT-C protocol defined in this part of ISO 14819 supports a data broadcasting service for travellers,
providing information about many kinds of traffic and travel events. Messages include traffic incident
information relating to national and regional routes and some urban roads and other information required by a
traveller, such as roadworks and weather information.

This part of ISO 14819 is based on the ALERT-C traffic message coding protocol, which was a product of
DRIVE Project V1029, "RDS Advice and Problem Location for European Road Traffic". The RDS-ALERT
project aimed to define standards for RDS-TMC, working in conjunction with the European Broadcasting
Union (EBU) and the European Conference of Ministers of Transport (ECMT).
The international standard has been implemented in many countries worldwide and, as a result of very
extensive implementation experience, it has matured with many changes from the earliest version of the
ALERT-C proposal of 1990. At that time CEN TC 278 Sub-working group (SWG) 4.1 developed the coding
protocol, herein and the event list described in ISO 14819-2; meanwhile CEN TC 278

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.
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 14819-1 was prepared by Technical Committee ISO/TC 204, Intelligent Transport Systems.
This second edition cancels and replaces the first edition (,62 ), which hasbeen technically
revised.
ISO 14819 consists of the following parts, under the general title Intelligent transport systems — Traffic and
travel information messages via traffic message coding:

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 standard 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 (Second edition –
2009).
The TTI information chain, from event to end-user is quite complex and the TISA value chain shown in Figure
1 helps to understand the key components:
Figure 1: The Traveller Information Services Association TTI value chain
A number of entities (e.g. companies, businesses) take part in one or more activities to complete the activities
shown in the value chain, two, 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 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 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 messages digitally and "silently" using the RDS-
TMC feature, which avoids the interruption of planned programmes. This TTI delivery method has a number of
advantages: TTI messages can be decoded into the language of the end user, regardless of location, more
messages can be made available and planned broadcast programme interruption is avoided, so make
delivery of TTI messages more timely and topical.
The ALERT-C protocol defined in this standard supports a data broadcasting service for travellers, providing
information about many kinds of traffic and travel events. Messages include traffic incident information relating
to national and regional routes and some urban roads and other information required by a traveller, such as
roadworks and weather information.

ISO/CD 14819-1
This standard is based on the ALERT-C traffic message coding protocol, which was a product of DRIVE
Project V1029, "RDS Advice and Problem Location for European Road Traffic". The RDS-ALERT project
aimed to define standards for RDS-TMC, working in conjunction with the European Broadcasting Union (EBU)
and the European Conference of Ministers of Transport (ECMT).
The standard has been implemented in many countries worldwide and, as a result of very extensive
implementation experience, it has matured with many changes from the earliest version of the ALERT-C
proposal of 1990. At that time CEN TC278 Sub-working group (SWG) 4.1 developed the coding protocol,
herein and the event list described in EN ISO 14819-2; meanwhile CEN TC278 SWG7.3 developed the
location referencing method which is described in EN ISO 14819-3. Subsequently the TMC Forum was
responsible for collecting specific additions and improvements intended for inclusion in this standard. Latterly
the Traveller Information Services Association (TISA) took over all responsibility (including TMC Forum
legacy) for maintenance of this standard, which now includes an up to date set of industry supported
enhancements to RDS-TMC.
