Overview
ISO/TR 17427-6:2015 - Intelligent transport systems (ITS) - Cooperative ITS (C-ITS) - Part 6: “Core system” risk assessment methodology - is an informative Technical Report that defines a consistent approach to identify and evaluate the critical technical and financial risks affecting C‑ITS core system deployments. It targets environments where institutional involvement provides direct or indirect support for core systems that underpin vehicle‑to‑vehicle (V2V), vehicle‑to‑infrastructure (V2I) and broader cooperative services.
This Technical Report:
- Focuses on risks associated with core systems (not in‑vehicle systems) and does not provide prescriptive solutions or a global quantified risk score.
- Raises awareness of principal causes of risk and offers a repeatable methodology for jurisdictions, core system operators and application service providers to assess their exposure.
Key topics and requirements
ISO/TR 17427-6:2015 organizes its guidance around practical risk assessment areas and tools. Major technical topics include:
- Risk categories and methodology: Technology risk, technical risk, financial risk and liability - plus operational phases and risk evaluation principles.
- Tools to assess risk: Frameworks for categorization, explanations of evaluation methods and operational phase considerations.
- Risks for individual core systems: Timely deployment, inter‑enterprise relationships, and adequacy of operations & maintenance (O&M) personnel.
- Risks for multiple core systems: Role and composition of a Core Certification Authority (CCA), External Support System (ESS) for security, O&M of ESS, security management, system performance management, privacy, and device certification.
- Terminology and scope: Definitions for core concepts such as IVS (in‑vehicle system), ITS‑S, Certificate Authority (CA), Registration Authority (RA), and GNSS reliance.
Note: the Report points to related standards and specifications for detailed technical or communications requirements but does not itself define those technical specifications.
Practical applications and who should use it
Primary users and beneficiaries:
- Public authorities and jurisdictions planning C‑ITS rollouts and policy frameworks.
- Core system operators responsible for platforms that support C‑ITS services.
- Application service providers delivering safety, traffic management or value‑added cooperative services.
- System integrators and solution architects assessing deployment risk, security dependencies and certification needs.
- Procurement, legal and risk teams evaluating financial, liability and operational exposure.
Use cases:
- Developing a risk register for a national C‑ITS deployment
- Assessing supplier relationships, CA/CCA governance and ESS dependencies
- Informing procurement clauses for O&M, privacy and security management
