This document specifies a graphic data dictionary (GDD), a system of standardized 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 (ITS).

Overview

EN ISO 14823-1:2024 / ISO 14823-1:2024 specifies a Graphic Data Dictionary (GDD) for intelligent transport systems (ITS). The GDD defines a standardized, language‑independent coding system for existing road traffic signs and pictograms used to deliver traffic and traveller information (TTI). Adopted by CEN as EN ISO 14823-1:2024, this first edition revision supersedes ISO 14823:2017 and improves global identification, flexibility and backward compatibility for ITS messaging and in-vehicle signage.

Key topics and technical requirements

Scope and conformance: Rules for implementing the GDD and achieving compliance with the standard.

Structure of pictogram codes: Detailed code format including category, nature and serial identification; support for relative object identifiers (OID) (Clause 7.3) and country code handling.

Numbering ranges: Predefined pictogram ranges for major types (e.g., danger/warning, regulatory, informative, public facilities, ambient/road conditions, supplementary panels) outlined in Clause 8.

Data modeling & serialization: ASN.1 descriptions of the GDD are provided (Annex A - version 2; Annex E - version 1) and associated attribute sets (Annex B/F). UML diagrams and specializations are included to assist implementers (Annex C/G/D).

Attributes and flexibility: New/updated attributes to support multiple pictogram variants; ability to include up to four pictograms per dictionary entry. Deprecated codes were removed and new country requests added.

Interoperability notes: Designed to be language‑independent to support consistent decoding and display across jurisdictions and to assist translation between different national sign representations.

Applications

In‑vehicle information systems and head‑unit displays for showing standardized signs and pictograms.

Traffic management centres and TTI providers for encoding sign-based messages in ITS communications.

Map and navigation providers to translate or localize sign representations between countries.

Road authorities and sign designers for harmonized sign identification and exchange.

OEMs and embedded systems vendors using ASN.1/OID implementations to integrate GDD into on‑board systems.

Related standards and notes

Supersedes ISO 14823:2017; part of the ISO 14823 series.

References country codes historically from ISO 3166-1 (background).

Annex I lists existing national signs included in the GDD; Annexes provide machine-readable schemas and examples to accelerate implementation.

Keywords: intelligent transport systems, graphic data dictionary, GDD, ISO 14823-1:2024, pictogram codes, ITS messaging, in-vehicle signage, ASN.1, object identifier, traffic signs.
