Overview
ISO/TS 14812:2022 - Intelligent transport systems - Vocabulary is a technical specification that provides a comprehensive, standardized set of terms and definitions for the Intelligent Transport Systems (ITS) domain. Published as the first edition in April 2022, the document establishes a consistent concept model and vocabulary to support interoperability, communication, documentation, and system engineering across ITS projects worldwide.
Key Topics
This vocabulary specification organizes ITS terminology into clearly defined categories, including:
- Core terms (entities, systems, architectures, time) - e.g., entity, system, transport system, surface transport system.
- Technology terms (physical objects, ITS stations, ITS applications) covering centre, field, personal and vehicle-related objects.
- Infrastructure terms (road components, junctions, separators, alternate-mode infrastructure).
- Location terms (location types and referencing).
- Service terms (generic services, ITS services, transport and shared-transport services, financial and contractual models).
- User and vehicle terms (traveller/occupant roles, vehicle components, attributes, automation, connectivity, speed and environment categories).
Additional features:
- Concept model diagrams in Annex A to illustrate term relationships.
- A bibliography and an alphabetical index of preferred, admitted, and deprecated terms.
- Notation that context-specific terms are indicated with bracketed context labels (for example, “”).
Practical applications
ISO/TS 14812:2022 is useful wherever precise ITS terminology is required:
- Standards development and harmonization - promotes consistent terminology across standards bodies and industry groups.
- System engineering and architecture - provides a common language for requirements, design, and verification of ITS architectures and interfaces.
- Procurement and contractual documents - reduces ambiguity in specifications and service agreements.
- Software and data modelling - supports ontologies, information models and data exchange formats by supplying agreed definitions.
- Policy, regulation and training - assists policymakers, regulators, and educators by clarifying key ITS concepts.
Who should use it
- ITS professionals, systems architects, and engineers
- Vehicle manufacturers and OEMs focusing on connectivity and automation
- Transport planners, operators and infrastructure owners
- Standards bodies, regulators and procurement teams
- Software developers working on ITS applications and data models
Related standards
- ISO online resources (ISO Online Browsing Platform) and IEC Electropedia are referenced for broader terminology alignment.
- ISO/TS 14812 complements other ITS and systems engineering standards (see ISO/IEC/IEEE references cited in the document).
