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 14819-2:2013(E)
Introduction
ISO 14819-2 is the second part of the ISO 14819 series of standards, covering the so-called ‘ALERT-C’
protocol encoded for transmission into the RDS-TMC feature. Therefore, this part of ISO 14819 is intended to
uniquely and solely be considered together with ISO 14819-1, for a complete understanding.
ISO 14819-1 fully describes the ALERT-C protocol concept and relationship with the RDS standard,
IEC 62106.
In this version of 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 of ISO 14819 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 series 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 other languages, based upon the normative ‘CEN-English’ have been produced and are
available from the Traveller Information Services Association (www.tisa.org).

Part 2:
Event and information codes for Radio Data System — Traffic

1 Scope
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 of ISO 14819 defines the ‘Events List’ to be used
in coding those messages.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

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 ISO 14819-1. The event
list is shown in the format of a database.
NOTE The first column of the Event list in 3.1.3, Table 2 shows line numbers to assist reading and use 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.
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.

SIST EN ISO 14819-2:2014
ISO 14819-2:2013(E)
3) The third column gives the decimal equivalent of the actual binary event code to be transmitted (see
Section 5.3.2 of 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 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 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 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 exclusively for events with nature F and duration type L or (L), can be found in Section
3.2. They contain no events of another type (except S).
10) The final column, "R", gives phrase codes (references) for use by TMC operators. An event may be a
single phrase event, or a combination of two or more phrases. Each phrase is allocated a phrase
code consisting at least of a single code letter (A - Z) and a code number (1 - 999). Single phrase
events are indicated by a single code letter and number of one or two digits (e.g. A1 - A99); expected
events are indicated by the normal phrase code followed by "E" (e.g. A1E), and dangerous events by
a following "D" (e.g. G6D); events with quantifiers can have three digits (e.g. A101). Longer lasting
forecasts are indicated by the letter F.
11) Not all the messages have to be used by a Service Provider but it is the Service Provider’s
prerogative to choose the most suitable ones for the service being provided. However a Service
provider would be well advised to take account and match the sub-set of messages with the
messages able to be presented in the terminal.
The Event List also contains several predefined combinations of single phrase events to make better
use of the available channel capacity. These combined events are indicated by the combined codes
of the constituent phrases (e.g. B11.C1).
NOTE The phrases used in combined events are not always word for word identical to the corresponding
phrases used in the single events. Binding words or small changes to the wording are necessary.

The code letters are not related to the update classes, but have the following meaning:
A: Level of Service
B: Incidents/Accidents
C: Closures
D: Lane Restrictions
E: Roadworks
F: Obstruction Hazards
G: Road Conditions
H: Weather
J: Winds
L: Environment
M: Temperature
P: Activities
Q: Delays/Cancellations
R: Dangerous Vehicles
S: Exceptional Loads
T: Traffic Equipment Status
U: Traffic Regulations
X: Parking
Y: Information
The code letter Z is used to indicate phrases from the List of Supplementary Information (see Section 3.2).
The phrase codes are not normative, but are only given as additional information about the contents of a given
event and should be helpful when implementing software.
