ISO/TR 17465-1:2014

Overview

ISO/TR 17465-1:2014 - Intelligent transport systems - Cooperative ITS - Part 1: Terms and definitions - provides the official definition of Cooperative-ITS (C-ITS) and describes the concept from multiple viewpoints. The technical report establishes common terminology and foundational concepts used across ITS standardization, clarifying how ITS stations, ITS services and ITS applications share information to improve safety, sustainability, efficiency, and comfort.

Key topics and technical requirements

• Core definition: C-ITS is a subset (or paradigm) of ITS in which ITS stations and ITS applications communicate and share information to advise or facilitate actions beyond stand‑alone systems.
• Terms and definitions: Precise meanings for terms such as ITS station (ITS‑S), ITS application, ITS service, local dynamic map (LDM), wireless communication platform, and bounded secured managed domain (BSMD).
• C-ITS attributes:
  • Collaboration between ITS‑S application processes across one or more ITS stations.
  • Information and resource sharing (communications, positioning, security) among vehicular, roadside, central and personal ITS subsystems.
  • Assignment of trust levels to received data and compliance with privacy regulations.
  • Requirement that cooperative activities must not increase hazard to other ITS activities or end users.
• Perspectives: Three complementary views are defined - communications network, service, and cooperative activity - to guide design and interoperability.
• ITS station reference architecture: Uses the ITS station model (ISO 21217) describing facilities, networking & transport, access, management, security and applications layers; mechanisms for LDM and message handling are noted.
• Technology‑agnostic: C-ITS is explicitly not tied to a specific communication medium; any suitable networking technologies and seamless switching between networks are supported.

Applications and practical value

• Facilitates design and specification of cooperative services such as safety warnings, traffic efficiency coordination and real‑time transit signalling.
• Guides architects and implementers in creating interoperable, trustworthy data exchanges between vehicles, roadside units and central systems.
• Helps ensure privacy, trust management and non-hazardous behavior in multi‑actor ITS deployments.

Who should use this standard

• ITS standards developers (SDOs), system architects and integrators
• Vehicle OEMs and telematics suppliers
• Road authorities, transport agencies and city planners
• ITS software developers, cybersecurity and communications engineers
• Policy makers and procurement teams specifying C-ITS interoperability
