ISO 14813-1:2024

Overview

ISO 14813-1:2024 - Intelligent transport systems (ITS) - Reference model architecture(s) for the ITS sector - Part 1: ITS service domains, service groups and services - provides a high‑level catalogue of ITS services to promote consistent, interoperable implementations. The third edition (2024) organises ITS functionality into service domains, service groups and individual services, and describes each service at a non‑prescriptive level. The document is largely advisory and informative and is intended as a common reference for architects, implementers and standards developers.

Key topics

• Service model structure: Definitions and characteristics of ITS service domains, service groups and individual ITS services to create a consistent reference architecture.
• Domain coverage: Descriptions include major domains such as traveller information, traffic management and operations, vehicle services, and freight transport services (and related cooperative ITS topics).
• High‑level service descriptions: Non‑prescriptive overviews that enable flexibility across national or local ITS architectures.
• Interoperability focus: Guidance to support common data definitions, use cases, user needs/user service requirements, and object identifiers for data concepts.
• Support for standards development: Intended as input for Technical Committees when creating standards for ITS communications, data exchange and architecture.

Practical applications

• Use ISO 14813-1:2024 to:
  • Define use cases and user requirements for ITS projects.
  • Create or align national ITS architectures with an international reference model.
  • Develop data dictionaries and identify common data elements and object identifiers for interoperable data exchange.
  • Inform procurement specifications and solution designs for ITS vendors and system integrators.
• Typical implementations include traveller information systems, real‑time route guidance, traffic signal control integrations, automated vehicle services, commercial vehicle administration and freight management platforms.

Who should use this standard

• National and local transport authorities and ITS programme managers
• Systems architects and integrators designing ITS solutions
• ITS product vendors and service providers
• Standards developers and ISO Technical Committees working on ITS communications, data and architecture
• Researchers and consultants producing ITS business or technical requirements

Related standards (context)

ISO 14813-1 complements other ITS and communications standards that define data formats, messaging and protocol specifications. It is best used together with domain‑specific ITS standards for data exchange, telemetry and cooperative ITS communications to achieve full interoperability.
