Introduction
EN ISO 14819-2 is the second part of the EN ISO 14819 series of standards, covering the so-called ‘ALERT-
C’ protocol which describes how traffic messages are coded for transmission as an ‘Open Data Application’
over the Radio Data System (RDS), a sub-carrier on FM radio transmissions. A complete understanding of
RDS-TMC can only be obtained by reading this part (part 2) together with the other parts of the EN ISO 14819
series of standards which are:
— EN ISO 14819-1 describes the ALERT-C protocol concept and relationship with the RDS standard, IEC
62106;
— EN ISO 14819-3 describes ways in which position and places are coded using ALERT-C;
— EN ISO 14819-6 describes how messages optionally may be encrypted for conditional access.
In this version of EN ISO 14819-2, the content of the ‘Events List’ have been altered. There are codes added
and descriptions modified.
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 columns formats 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. CEN-English uses metric measurements throughout, and the end-to-end chain from Service
Provider to end-user device shall also use metric in all processing steps. In some countries (especially USA,
UK) and indeed for drivers from these countries visiting ‘metric’ countries, presentation of messages is
preferred in non-metric units – ‘miles’, ‘mph’ etc. For this reason, Annex A and Annex B (so-called GB-
English) present tables that ‘convert’ for presentation from metric to non-metric units. Note that conversions
are deliberately not designed to be mathematically accurate, as to do so would result in non-integer values,
instead the conversions results are rounded to the nearest ‘logical’ value.
Translations into further other languages, based upon the normative ‘CEN-English’ have been produced and
are available from the appropriate national bodies. TISA (www.tisa.org) can help with contacting these
organisations.
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.

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 , 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 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 quantifier field, containing the reference numbers of quantifiers listed in
the table at the end of the event list. The position of the quantifier in the event, plus in some cases
some accompanying words, is shown by (.Q.) within the text. Use of these quantifiers is usually
optional, however a few event messages have no meaning without the quantifier. The use of
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 5.4.7 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 and how to present events to the driver.
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 to which the event
belongs. Update classes 1…31 are listed in Section 3.1. Update classes 32…39 are exclusively for
events of the forecast nature ‘F’ with duration type L or (L) - these are in Section 3.2. Other than
events of type S, these classes contain no other events.

ISO/DIS 14819-2:2019(E)
10) The tenth column “P”, if it contains a code, indicates an event that experience has shown can be
misinterpreted, and as such in due course, this event may be deprecated. The code in this cell
indicates the code that should be used in preference, as it better represents the event.
11) 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 a one or two digit number (e.g. A1 - A99); expected
events are indicated by the normal phrase code followed by ‘E’ (e.g. A1E), and where a risk of
danger exists 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’.
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 that although the event lists (Main, Forecast and Supplementary) together contain around 1,700
messages, as explained above, most are composed by combining two or more single phrase
messages, so in practice there are only a few hundred unique phrases that need to be stored by the
terminal, which when combined, form the longer composite messages.
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 may be 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
Z: Indicates 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.
12) The event list is comprehensive and contains many messages that may be rarely or even never used
by particular Service Providers. In general each Service Provider will use a sub-set of the complete
list, according to their need and the needs of the road network for which they are providing
information.
Although individual Service Providers may use only a sub-set of messages, terminal manufacturers
are encouraged to support all messages in the event list to ensure messages from any Service
Provider can be presented to the end-user.
