ISO/TR 17465-2:2015

Overview

ISO/TR 17465-2:2015, "Intelligent transport systems - Cooperative ITS - Part 2: Guidelines for standards documents," is a technical report from ISO/TC 204 that provides guidance on how to structure multi-part ISO/CEN standards for Cooperative-ITS (C-ITS) services and applications. Its aim is to make large, multi-part standards easier to navigate and maintain by recommending a common, consistent part numbering and contents scheme for Cooperative-ITS standards.

Key Topics

• Structure for multi-part standards: Recommends a consistent organization so users can find architecture, data, interfaces, security and other material in predictable parts.
• Recommended part numbering: Provides a standard list of parts (1–10) typically used in C-ITS multi-part standards:
  • Part 1: Architecture / Application base standard
  • Part 2: ITS station management
  • Part 3: Privacy
  • Part 4: Data
  • Part 5: Interfaces
  • Part 6: Network / Protocols
  • Part 7: Identifiers
  • Part 8: Facilities / APIs
  • Part 9: Conformance testing
  • Part 10: Security
• Contents of Part 1: Defines the base application/architecture and provides an index/summary of the other parts.
• Guidance for Parts 2–10: Outlines the expected focus for each part (e.g., ITS station management, data definitions, interface specifications, testing and security).
• Use of annexes: Explains when annexes in Part 1 may be used instead of separate parts.
• Coordination and maintenance: Emphasizes the need to involve other technical committees, working groups (e.g., security and privacy experts), and to plan for lifecycle maintenance of multi-part standards.

Applications and Who Uses It

ISO/TR 17465-2:2015 is intended for:

• Standards developers and SDOs designing multi-part Cooperative-ITS standards.
• System architects and ITS implementers who need to understand how requirements are organized across documents.
• Conformance test houses and QA teams preparing test plans that map to standardized parts (e.g., Part 9).
• Procurement officials and policymakers who require clear, maintainable standards for interoperability, privacy and security in V2V, V2I and broader C-ITS deployments.

Practical benefits include improved discoverability of requirements, consistent document lifecycle management, clearer coordination across security, privacy and data domains, and reduced duplication across standards.
