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 14823 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 278, Road transport and traffic telematics, in collaboration with Technical Committee ISO/TC 204,

Introduction
This Technical Specification presents a Graphic Data Dictionary (GDD) which has been developed with the
intent of creating a common basis for transmitting graphic information data that can be, irrespective of
language or regional differences, decoded and understood by the users who obtain TTI (pre-trip and in-trip
information) service through TTI system operators such as traffic management centres (TMCs), traffic
information centres (TICs) and value-added service providers (VASPs) which add value to the TTI. Adopting
unified graphic data is expected to improve the understandability of the graphic information by the user and
thereby increase the convenience of TTI systems.
The purpose of GDD is, in order to facilitate the data exchange between media, to catalogue graphic images
like traffic signs and pictograms specified and used uniquely in each country and to assign them a certain
code.
Elements of Graphic Data
These include:
⎯ full name of the pictogram,
⎯ definition of the pictogram,
⎯ code for the pictogram,
⎯ attribute(s) of the pictogram, and
⎯ pictogram itself.
Normative items in this document are the coding scheme involving the full name, definition and attributes to
define each graphic image. It is not intended to create and specify a common design of graphic images.
Application of Graphic Data
Graphic data shall be stored in advance as a database by TTI system operators (such as TMC, TIC etc.),
VASP, or in media systems, and then used as a part of TTI for data exchange among these entities. "The
GDD" is a database that registers the codes and attributes of a set of graphic data in a systematic manner.
Message Creation
Data elements to be stored in the database of a TIC shall be those created by using TTI collected in the TIC.
Similarly, graphic data shall be those coded beforehand and registered into the database. Messages to be
dealt with in this Technical Specification are to be generated basically with data elements registered in the
database of the TIC.

1 Scope
This Technical Specification presents a system of standardized codes for existing signs and pictograms used
to deliver traffic and traveller information (TTI). The coding system can be used to form messages to be
handled by respective media systems, graphic messages on on-board units, and media system information on
TTI dissemination systems (VMS, PC, PAT, etc.) (including graphic data). These types of information are
required by travellers for their pre-trip planning as well as their in-trip plan modification based on information
obtained through media systems.
As shown in Figure 1, a system handling graphic messages generally comprises TTI system operators, media
systems and communication networks interconnecting these systems.
This Technical Specification relates to:
⎯ TTI systems operators which include
⎯ Traffic Management Centres (TMC),
⎯ Traffic Information Centres (TIC),
⎯ Parking Information Centres (PIC),
⎯ Public Transport Centres (PTC),
⎯ Value-Added Service Providers (VASP), and
⎯ others;
⎯ media systems which include
⎯ On-board Units (OBU),
⎯ Variable Message Signs (VMS),
⎯ Personal Computers (PC),
⎯ Public Access Terminals (PAT), and
⎯ others.

ISO/TS 14823:2008(E)
6.2 Information Elements
Information elements (IEs) contained in messages provided by pre-trip and in-trip information services can be
broadly divided into these types. This classification conforms to the “Final Act and Related Documents”
enacted by the “United Nations Conference on Road Traffic (UNCRT).”
Table 1 — Information Elements
Type of Service (Division) Subdivision Nature
1) Traffic Sign Information a) Danger warning Warning / Priority sign information
c) Regulatory Priority sign information
Prohibitory or restrictive sign information
Mandatory / End sign information
c) Informative Advance direction sign information
Direction sign information
Road/ Place identification sign information
Confirmatory sign information
Pedestrian crossing sign information
Other sign information providing information
useful to the drivers of vehicles
Lane affectation
2) Public Facilities a) Public facilities Information giving notice of public facilities
Information which may be useful to road users
3) Ambient/Road Condition b) Ambient conditions Information indicating ambient conditions
Information which may be useful to the drivers of
vehicles
c) Road conditions Sign information indicating road conditions
which may be useful information for drivers
of vehicles
The ‘Traffic Sign Information’ is subdivided into three categories, each of which defines information for each
traffic sign established in each member country (see Section 7.5.1 ‘Country Code’). Each subcategory may be
divided further based on its properties. The Public Facilities Information indicates the existence of certain
public facilities and their service details (e.g., toilets, restaurants, first aid facilities, etc.). The “Ambient/ Road
Condition Information” is concerned with the ambient condition of a roadway or local condition which may
affect the flow of road traffic (such as bad weather and traffic congestion). IEs are all defined with their full
names and are provided in the form of pictograms easily recognizable by the users. Pictograms to be used for
information display may vary from country to country, from political jurisdiction to political jurisdiction, or from
system operator to system operator.

ISO/TS 14823:2008(E)
6.3 Data Elements
Used as a “Pictogram Code” when transmitting IEs (described in Section 6.2) as communication data is a
combination of the following four Data Elements (DEs): country code data, service category data pictogram
category data, and attribute indicator code. When these “Communication Data” (consisting of pictogram code
and attributes) are provided to the users, they are served with four components: the unified full name, and
definition of a pictogram, details of its attributes if any, and the pictogram itself. They are called User Service
Data. The data configuration of the IEs (described in Section 6.2) is as follows:
6.3.1 Communication Data:
Pictogram Code
Country code data DE 1 (the code number assigned to the country to which the system
operator belongs);
Service category data DE 2 (the code number assigned to the category of IE);
Pictogram category data DE 3 (the code number assigned to the category of a pictogram type
under the service category);
Attribute indicator code data DE4 (the code number indicating whether any attributes are
attached to the pictogram);
Attributes
Attributes When any attributes are needed for details, one or more of the eight
attributes are added.
6.3.2 User Service Data:
Full name
Definition
Attributes
Pictogram
6.4 Data Structure
Each of the four DEs described in Section 6.3 has its own data field. By combining these data fields, the IEs
described in Section 6.2 can be represented in various ways. Each data field is coded in units of DEs to create
a certain IE. As a rule, every data field in every DE is represented by one integer or one letter. See Section
7.5 for details of the coding rule, and Section 7.7 for the attributes.
The coded data structure is as follows:
