Introduction
0.1 Design principle
This document specifies a Graphic Data Dictionary (GDD) that has been developed with the intent of
creating a common basis for transmitting encoded information for existing road traffic signs and
pictograms. The coding system has been developed to be language independent, such that data that can
be interpreted, irrespective of language or regional differences. It supports Intelligent Transport System
(ITS) application such as in-vehicle signage or in-vehicle information.
This document supports
— the efficient IT-centric encoding for ITS messaging to represent specific road traffic signs and
pictograms, and
— the consistent decoding of encoded road traffic signs and pictogram data for display in ITS.
This document can support the translation of signs and pictograms with a similar purpose from the
representation used in one country to the representation used in another country.
0.2 Background of revision
The first edition of Graphic Data Dictionary was published in 2017.
This first edition used the country code stipulated by ISO 3166 1 to distinguish the country where Graphic
Data Dictionary is provided and used the following numbering structure to identify the pictogram codes
stipulated in the 8.
— The two-digit category of the sign
— The one-digit nature of the sign
— The two-digit serial number of the sign
However, this mechanism lacked a global identification of pictogram codes and a flexibility when adding
new pictogram codes.
To cope with these issues, the second edition of Graphic Data Dictionary has been developed.
0.3 Backward compatibility
The second edition of Graphic Data Dictionary has been developed to be backward compatible with the
first edition of the Graphic Data Dictionary to assist in transitions from earlier implementations, while
not hindering spreads of the first edition of Graphic Data Dictionary and being able to support many new
features.
Specifically, the Graphic Data Dictionary allows the selection of 2 versions described in 7.1.
The Graphic Data Dictionary allows to use both the ASN.1 description specified in Annex A for the second
version and in Annex E for the first version, and both the attributes specified in Annex B for the second
version and in Annex F for the first version.

5 Conformance
An implementation is conformant with this document when the following conditions are met.
— The implementation and transmission of graphic data shall comply with requirements listed in this
document.
— The pictogram code shall be selected from the categorized codes listed in this document.
6 Requirements
The intended usage of this document is to support the efficient IT-centric encoding for ITS messaging to
represent specific road traffic signs and pictograms and the consistent decoding of encoded road traffic
signs and pictogram data for display in ITS.
This document supports the translation of pictograms with similar purpose from the representation used
in one country to the representation used in another country. For illustrative purposes, it is foreseen that
this document can be used to encode information concerning a specific pictogram that is then embedded
into other information to be exchanged; if needed, on receipt of this information, the receiver can use the
contents of this document to decode the information concerning the specific pictogram to support display
across a range of dissemination systems. Examples of these dissemination systems may include: Traffic
Control Centre system user interfaces; Variable Message Signs; Public Access Terminals; mobile personal
information systems; and, on-board units.
Requirements for ITS applications which utilize the Graphic Data Dictionary are as follows.
— Graphic data shall consist of a version number, relative object identifier or country code, and optionally
Attribute indicator.
— Category code shall be decided based on Table 1.
— Warning pictogram code shall be selected from Table 2.
— Regulatory pictogram code shall be selected from Table 3.
— Guide pictogram code shall be selected from Table 4.
— Public facilities pictogram code shall be selected from Table 5.
— Supplementary panel and additional panel pictogram code shall be selected from Table 6.
— Integer value which indicate the direction shall be determined based on Table B.3 or D.3.
— If Attribute indicator is on, graphic data shall include attributes listed in Table B.1 or D.1.
— When transmitting Graphic data, it shall be coded based on the ASN.1 module specified in Annex A
or on the ASN.1 module specified in Annex E.
NOTE For transmission efficiency purposes, compression can be considered. This is outside the scope
of this document.

7 Structure of Graphic Data Dictionary
7.1 General
The Graphic Data Dictionary provides a taxonomy of all registered sign types by assigning each sign type
with a globally unique category code. This category code allows the meaning of virtually any sign used
for surface transport to be adequately conveyed in a language independent manner with a very short
identifier coupled with optional attributes.
There are 2 versions when determining the structure of the Graphic Data Dictionary.
The first one uses the sequence of the country code and category code as specified by the GddStructure
in Annex E.
This version is expected to be used mainly when expanding or maintaining the existing C-ITS applications
which presently use GDD edition 1 (ISO 14823:2017).
The second one uses the object identifier of the category code by using the ASN.1 RELATIVE OID specified
in 7.3. This mechanism has been introduced to cope with a global identification of pictogram codes and a
flexibility when adding new pictogram codes.
In addition, some of the elements have been harmonised with DATEX II to be used in VMS signs.
It is up to each application or service to define how to use these versions.
However, for reasons of facilitating implementations, it is recommended to avoid mixing versions in the
same applications or service.
Details of version 2 can be found in the Annex A, B, C and D while details of version 1 can be found in the
Annex E, F and G.
7.2 Current and deprecated signs
There are a number of signs in the previous edition of ISO 14823: 2017 that are deprecated (no longer
relevant or duplicated). Each sign code in this edition of the GDD is labelled “current” or “deprecated”
together with a date of revision. Using this labelling enables legacy applications to continue to use these
deprecated sign codes but signals to new users that it is wise to use only current labelled codes. To ensure
backward compatibility no code is reused, so that if a deprecated code is transmitted and the receiver
does not recognise it no action is taken. In the future it is possible that some codes might be set to
“obsolete”.
7.3 Relative object identifier
International object identifier tree is a tree whose root corresponds to this Recommendation or
International Standard and whose nodes correspond to Registration Authorities responsible for
allocating arcs from a parent node.
The pictogram codes are registered on the international object identifier tree under the arc { joint-iso-
itu-t(2) its(28) gdd(5) }. The first three sub-arcs follow the numbering structure:
— The two-digit service category of the sign
— The one-digit nature category of the sign
— The two-digit serial number of the sign

ISO 14823-1:2021(E)
ISO/DIS 14823-1:2022(E)
The taxonomy defined by the Graphic Data Dictionary allows maximum interoperability among
implementations that might differ in their level of support of GDD details. In other words, while the GDD
has been designed to support numerous potential use cases that require various levels of detail and
virtually all sign types that might be encountered within surface transport, GDD has also been designed
to accommodate applications (especially receiving applications) that might not support the full scope of
the GDD. Specifically, the taxonomic structure of GDD allows a sender to provide a very detailed category
code; if the receiver does not understand the complete taxonomic sequence, it should still be able to
classify the sign under a parent category (or understand that it is safe to ignore).
For example, if a receiving application is notified of a sign with an object identifier of { joint(2) its(28)
gdd(5) warning(11) warning3(3) wildAnimal(63) unspecified(0) au(36) kangaroo(x) } ), it might be able
to display the intended Australian-specific kangaroo crossing warning sign to the driver. Another
application might generalize all object identifiers starting with { joint(2) its(28) gdd(5) warning(11)
warning3(3) wildAnimal(63) } sign to a generic wild animal crossing sign. And another application might
generalize all object identifiers starting with { joint(2) its(28) gdd(5) warning(11) } to be a generic
warning sign. The level of detail supported by an application is dependent upon the purpose of the
receiving application and is beyond the scope of the GDD.
To ensure that all signs described by the GDD are placed into this taxonomy, the GDD conveys the object
identifier of the category code by using the ASN.1 RELATIVE OID type with a root node of { joint(2) its(28)
gdd(5) }. This allows a more efficient encoding of the object identifier while also ensuring that all codes
can be generalized according to the defined taxonomy. This structure still allows for further regional
specializations of the category codes defined within this standard according to the process defined in
Annex D.
7.4 Country code
ISO 3166-1 is used to encode the countryCode in GddStructure.pictogramCode using two-letter codes in
uppercase in ISO/IEC 8859-1 encoding. For example, if the on-board unit has multiple countries'
pictograms, it can render pictogram on the display in accordance to each county code when the traveller
driving through adjacent countries.
7.5 Pictogram code and OID node information
Category code consists of a service category code and a pictogram category code. Service category has
following four types of categories:
— Traffic signs are officially established pictograms in each country to control traffic using warning,
regulatory or informative sign.
— Public facilities indicate the existence of certain public facilities and their service details (e.g. toilets,
restaurants, first aid facilities, etc.).
— Ambient conditions indicate weather condition on the road (e.g. rainfall, flood, fog, etc) and road
conditions (traffic congestion, accident, etc) which may effect the traffic flow.
— Supplemental panels are attached to the main signs to provide supplemental information using text
or numbers.
Pictograms to be used for information display may vary from country to country, political jurisdiction to
political jurisdiction, or system operator to system operator.
