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.

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 documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical

Barriers to Trade (TBT) see the following URL: w w w . i s o .org/ iso/ foreword .html.

Introduction

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.

Intelligent transport systems — Graphic data dictionary
1 Scope

This document specifies a graphic data dictionary, a system of standardised codes for existing road

traffic signs and pictograms used to deliver Traffic and Traveller Information (TTI). The coding system

can be used in the formation of messages within intelligent transport systems.

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 country code, category code, and optionally Attribute indicator.

— Category code shall be decided based on Table 1.
— 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.
— Ambient/road conditions pictogram code shall be selected from Table 6.

— Integer value which indicate the direction shall be determined based on Table B.3.

— If Attribute indicator is on, graphic data shall include attributes listed in Table B.1.

SIST EN ISO 14823:2017
ISO 14823:2017(E)

— When transmitting Graphic data, it shall be coded based on the ASN.1 code described in Annex A.

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 shall consist of country code, category code. The Graphic Data Dictionary

supports the definition of optional attributes.
7.2 Country code

Country code stipulated by ISO 3166-1 is used to distinguish the country where Graphic Data Dictionary

is provided, as the style of pictograms can be different in each country. 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.
7.3 Category code
7.3.1 Categorization policy

Category code consists of a service category code and a pictogram category code. Service category has

following three types of categories: Traffic sign, Public facilities and Ambient/road conditions.

— Traffic signs are officially established pictograms in each country to control traffic using warning,

regulatory or informative sign.

— Public facilities indicates the existence of certain public facilities and their service details (e.g.

toilets, restaurants, first aid facilities, etc.).

— “Ambient/road condition” 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).

Pictograms to be used for information display may vary from country to country, political jurisdiction

to political jurisdiction, or system operator to system operator.
