ISO 17427-1:2018

Overview - ISO 17427-1:2018 (Cooperative ITS roles and responsibilities)

ISO 17427-1:2018 provides a technology‑agnostic, organizational blueprint for deploying and operating Cooperative Intelligent Transport Systems (C-ITS). The standard defines actor‑invariant roles and responsibilities required to deliver C-ITS services across all road classes and for any actors involved in service provision. Presented from an enterprise (organizational) viewpoint based on the Open Distributed Processing (ODP) reference model (ISO/IEC 10746 series), it supports vehicle‑to‑vehicle, vehicle‑to‑infrastructure and infrastructure‑to‑infrastructure communications without prescribing specific communication modes or technologies.

Key topics and technical requirements

• Roles and responsibilities: Defines internal (C-ITS‑specific) and external (non‑C‑ITS but involved) roles required to achieve service provision.
• Enterprise viewpoint: Uses ODP’s enterprise viewpoint to map organizational structures, processes and information exchanges to roles.
• Methodology: Provides a process‑oriented methodology to identify service‑specific roles and assign responsibilities (see Annex A example: hazard location warning).
• Role examples: Describes roles such as Functional operation, System management, System operation and Policy framework, and how they interact.
• Profiles and scenarios: Includes guidance on creating profiles and sample scenarios to apply roles across services (Annex B).
• Privacy & data protection: Emphasizes compliance with privacy requirements (ISO/TR 12859 and national laws) due to high volumes of C-ITS data exchanges.
• Compliance guidance: Outlines how to use the standard for developers and implementers of C‑ITS application standards.

Practical applications - who uses ISO 17427-1

This standard is intended as a blueprint for organizations that design, deploy or regulate C‑ITS services:

• Transport authorities and road operators designing organizational structures for C‑ITS service delivery
• System integrators and ITS solution providers mapping functional responsibilities across stakeholders
• Vehicle OEMs and infrastructure vendors aligning interfaces and operational roles
• Standards developers and test bodies using the methodology to derive service‑specific roles
• Policy makers and regulators defining governance, privacy, and operational requirements

How it helps implement C‑ITS

• Helps translate technical architectures into executable organizational models.
• Enables clear assignment of responsibilities across multi‑stakeholder C‑ITS ecosystems.
• Supports interoperability and governance planning while respecting privacy and legal constraints.
• Provides reusable patterns (profiles, scenarios) to accelerate service rollout.
