Full title and description

STB DIN EN ISO 14823-1 E 2022-02 — Intelligent transport systems — Graphic data dictionary — Part 1: Specification. This entry refers to the DIN/CEN/ISO adoption path and draft versions dated around February 2022 (prEN / ISO/DIS stage) for the graphic data dictionary used in traffic and traveller information systems; the project was later published as ISO 14823-1:2024 (final international publication).

Abstract

This standard specifies a Graphic Data Dictionary (GDD): a system of standardized codes and identifiers for road traffic signs, pictograms and other graphical symbols used to deliver traffic and traveller information (TTI). The coding system is intended for use in message formation and exchange within Intelligent Transport Systems (ITS), enabling consistent, language‑independent transmission and display of graphic information (for example on in‑vehicle displays, traffic control centre systems and information services).

General information

• Status: Draft / prEN national adoptions (reference E 2022-02) later superseded by the published international standard ISO 14823-1:2024.
• Publication date: Draft/prEN stage: February 2022 (notation E 2022-02); final international publication: May 2024.
• Publisher: ISO (international); national adoptions and draft publications handled by CEN/CENELEC and national bodies such as DIN (Germany) and other national standards bodies.
• ICS / categories: 35.240.60; 43.040.15.
• Edition / version: Identified as DIN EN ISO 14823-1 E 2022-02 for the draft/national stage; finalized as ISO 14823-1:2024 (Edition 1, 2024-05).
• Number of pages: Draft/prEN publications list around 85–86 pages; the finalized ISO 14823-1:2024 specification is 73 pages.

Scope

The standard defines the structure, coding principles and data elements of a Graphic Data Dictionary for traffic and traveller information systems. It covers the representation and coding of road traffic signs, pictograms and related graphic elements so they can be referenced, transmitted and rendered consistently across ITS platforms and services (e.g., traffic control centres, service providers, in‑vehicle systems and dissemination systems). The scope includes rules for identifiers, attributes and classifications required to support pre‑trip and in‑trip information exchange.

Key topics and requirements

• Definition of a Graphic Data Dictionary (GDD) structure and coding model for graphic symbols used in TTI.
• Standardized identifiers and classification for road signs, pictograms and related graphical elements.
• Rules for attributes, variants and metadata that allow unambiguous rendering and interpretation across platforms.
• Guidance for use in message formation, data exchange and in‑vehicle rendering within ITS architectures.
• Compatibility and alignment with earlier ISO/TS and ISO publications on traffic/traveller information data.

Typical use and users

Primary users are ITS system designers, traffic control and information centres, navigation and map data providers, vehicle HMI and telematics developers, service providers delivering TTI, and national standards committees implementing or adopting the GDD for local use. Typical uses include encoding traffic signage for broadcast or on‑board display, preparing machine‑readable symbol libraries for navigation systems and ensuring consistent multimedia presentation of traffic information.

Related standards

Related documents include ISO 14823 (earlier 2017 edition, withdrawn), ISO/TS 14823:2008 (Technical Specification), and the EN/prEN draft documents associated with the CEN/CENELEC adoption process; the 2024 publication (ISO 14823-1:2024) replaces the earlier withdrawn/technical specification versions. National adoptions (DIN, BSI, ÖNORM, etc.) track the EN/ISO lifecycle.

FAQ

Q: What is this standard?

A: It is the Graphic Data Dictionary specification for Intelligent Transport Systems — a standardized coding system for road signs and pictograms used in traffic and traveller information (the entry titled here refers to the DIN/CEN/ISO draft stage labelled E 2022-02; the finalized international standard is ISO 14823-1:2024).

Q: What does it cover?

A: It covers the structure and rules for encoding graphical symbols (signs and pictograms), their identifiers and metadata so that graphic traffic information can be transmitted and rendered consistently across ITS services and in‑vehicle systems.

Q: Who typically uses it?

A: ITS vendors, traffic control and information centres, navigation and map data providers, vehicle HMI developers, service providers and national standards bodies adopting the EN/ISO outputs.

Q: Is it current or superseded?

A: The 2022-02 draft/prEN stage has been superseded by the published international standard ISO 14823-1:2024 (published May 2024). Users should reference the 2024 published text for the definitive, current specification.

Q: Is it part of a series?

A: Yes — this entry is Part 1 (Specification) of the Graphic Data Dictionary work; the series and related technical specifications/history include earlier ISO/TS and ISO editions and potential subsequent parts or application guidance as developed by ISO/TC 204 and cooperating CEN technical committees.

Q: What are the key keywords?

A: Graphic Data Dictionary (GDD), traffic signs, pictograms, ITS, traveller information, message coding, in‑vehicle display, standard identifiers.
