Foreword
The text of the International Standard from Technical Committee ISO/TC 204 "Transport information and control
systems" of the International Organization for Standardization (ISO) a European Standard by Technical Committee
CEN/TC 278, "Road transport and traffic telematics", the secretariat of which is held by NEN.
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by December 2003, and conflicting national standards shall be withdrawn at the latest
by December 2003.
This document supersedes ENV 12313-2:1997.
Attention is drawn to the fact that there may be Intellectual Property Rights (IPR) in relation to certain provisions of
this standard, especially in regard to the implementation of terminal products. The technical experts of TC 278 were
unable to identify such claims due to the complicated legal issues involved. IPR holders should notify CEN of their
claims.
No known national standards (identical or conflicting) exist on this subject.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,
Slovakia, Spain, Sweden, Switzerland and the United Kingdom.
Introduction
EN ISO 14819-2 is the second part of the EN 12313 / EN ISO 14819 series of standards, covering the so-called
‘ALERT-C’ protocol encoded for transmission into the RDS-TMC feature. Therefore, this standard must uniquely
and solely be considered together with EN ISO 14819-1, for a complete understanding.
EN ISO 14819-1 fully describes the ALERT-C protocol concept and relationship with the RDS standard, IEC
62106:2000
In this version of EN ISO 14819-2, the content and the structure of the ‘Events List’ have not been altered, but
recent work from the FORCE/ECORTIS Projects regarding translations and a number of improved formatting ideas
suggested by the EPISODE Project, have been introduced. Additionally mention is made of suggested ‘Event List’
sub-sets.
In particular, this part contains the special meta-language, in the so-called ‘CEN-English’, which the technical
experts of CEN TC 278 agreed would be the only and sole source for all coded descriptions used in RDS-TMC.
This methodology has allowed agreement in important details for the many hundreds of event phrases, so included,
even though subtle linguistic differences were perceived and need to be allowed for in terms of end-user
presentation. Thus the French and German language editions of this standard have the same form as this English
language edition. All three language editions have exactly the same sections 3.1.3 Event List, 3.2.2 Supplementary
Information List and 3.3.2 Forecast Event List written in ‘CEN-English’. Each language edition comprises
Informative annexes providing those lists again in three or four column format showing the ‘CEN-English’
description and the ‘transformed’ language (not necessarily a direct literal translation, but a comprehensible
transformation of the specific intent of the ‘CEN-English’) description in their respective languages.
Translations into further other languages, based upon the normative ‘CEN-English’ have been produced and are
available from the TMC Forum web site, at URL: www.tmcforum.com.
Further work has been undertaken by the FORCE/ECORTIS Projects to define subsets of the Events List covering
safety and crisis phrases, which are now embodied in the SACEL and SACEL + Events Lists, which can also be
found on the TMC Forum web site, at URL: www.tmcforum.com
1 Scope
EN ISO 14819-1 describes the ALERT-C protocol concept and message structure used to achieve densely coded
messages to be carried in the RDS-TMC feature. This part (2) of the EN ISO 14819 series of standards defines the
‘Events List’ to be used in coding those messages.
2 Normative references
This European Stanadard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this European
Stanadard only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies (including amendments).

3 Event and Information codes for Traffic Message Channel
3.1 Event list
3.1.1 Explanatory notes
1) The event list is divided into update classes, indicated by the various sections. These update classes are
used for terminal message management, as indicated in Section 6.1 of EN ISO 14819-1. The event list is
shown in the format of a database.
NOTE: The first column shows line numbers to assist reading of the database
2) The second column gives a ‘technical language’ (so-called CEN-English) description of the event code, of
which the code is shown in the third field. Appropriate authorities of each country have been responsible
for the exact descriptions in other languages, in conformity with the definitions given in the DATEX Data
Dictionary.
This will ensure precise definitions and use of the event codes in the transmission layer. Individual terminal
implementations may handle these (translated) descriptions with some flexibility. To allow a more effective
presentation however without altering the meaning.
3) The third column gives the decimal equivalent of the actual binary event code to be transmitted (see
Section 5.3.2 of EN ISO 14819-1). These codes are purely internal to the RDS-TMC system and should
not be used for referencing events or composing messages in other operator systems. Undefined codes
are reserved for future system additions.
4) The fourth column, headed "N", is the nature of the event. The general meaning of the codes is as follows:
(blank) - information
F - forecast
S - silent: no message shall be presented to the end-user
5) The fifth column, "Q", is the optional quantifier field, containing the reference numbers of quantifiers listed
in the table at the end of the event list. The position of the optional quantifier in the event, plus in some
cases some accompanying words, is shown by (.Q.) within the text. Use of these optional quantifiers is
described in Section 5.5.6 of EN ISO 14819-1.
6) The sixth column "T" is the duration type. "D" indicates "dynamic" events of short duration and "L" indicates
longer-lasting events (see Section 5.4.10 of EN ISO 14819-1). If this code is bracketed ( ), or if the time-of-
day quantifier (no.7) is actually used in the message, no duration shall be presented to the user. In these
cases, the duration indicates persistence, used for message management only.
7) The seventh column "D" is the default directionality of the event. "1" indicates that one direction, and "2"
that both directions of traffic are normally affected by the event. TMC terminals can use this field to help
determine which events to present to the driver and how.
8) The eighth column "U" is the default terminal urgency, with values "X" for extremely urgent, "U" for urgent,
and blank for normal events (see Section 5.4.5 of EN ISO 14819-1).
9) The ninth column, "C", gives a numerical representation of the update class the event belongs to. Only
update classes 1 - 31 can be found in 3.1. Some update classes (classes 32-39 in the present list), which
are e
