PD ISO TR 17465 — Cooperative Intelligent Transport Systems Technical Reports

🚗 PD ISO TR 17465 is the UK implementation, published by BSI, of the ISO/TR 17465 series of technical reports, prepared by UK Technical Committee EPL/278 (Intelligent transport systems) and focused on Cooperative Intelligent Transport Systems (Cooperative ITS, C-ITS). The three parts in this batch are: Part 1, terms and definitions; Part 2, guidelines for standards documents; and Part 3, release procedures for standards documents. Together they form the “foundational trio” of C-ITS standardisation — unified terminology, well-structured documents, and controlled release procedures — an important support for the standardisation of connected vehicles (V2X) and cooperative transport systems.

1. Series Overview 📌

With the development of intelligent connected vehicles and vehicle-road cooperation, C-ITS requires a coordinated, consistent standards system. The ISO/TR 17465 series is precisely the top-level guiding document for C-ITS standardisation: it defines C-ITS terminology (Part 1), guides how to organise the structure and content of multi-part C-ITS standards (Part 2), and specifies the release procedure for standards documents (Part 3). BSI adopts them as “PD ISO/TR 17465-xxx”.

The three parts are developed with the participation of committee EPL/278, progressing logically from “what it is” (terminology) to “how to write” (guidelines) to “how to release” (procedures), providing the methodology for building the C-ITS standards system.

2. Series Structure and Part Highlights 📋

Part 1 is classified under ICS 01.040.03/01.040.35/03.220.01, and Parts 2 and 3 under ICS 01.120/03.220.01/35.240.60. All are handled by the same UK technical committee EPL/278, forming the methodological basis for C-ITS standardisation.

3. Key Technical Requirements 🔧

1. Terms and Definitions (Part 1)

Part 1 provides a unified terminology system for the C-ITS field, mainly including:

• Definition of Cooperative-ITS: a normative definition of cooperative ITS;
• C-ITS attributes and features: key attributes and features (e.g., cooperation, information exchange, autonomy);
• Perspectives: explaining C-ITS from technical, operational, and regulatory viewpoints;
• Symbols and abbreviations: unified common symbols and abbreviations for cross-domain communication.

2. Guidelines for Standards Documents (Part 2)

Part 2 provides structured guidance for C-ITS standards writers, mainly including:

• Organisation of multi-part standards: how to organise the overall structure of a multi-part C-ITS standard;
• Structure of parts: the structure and content arrangement of each part;
• Use of annexes: when to use annexes rather than adding new parts.

3. Release Procedures (Part 3)

C-ITS standards involve coordination across vehicle-road cooperation, communications, security, and other domains, so version release must be controlled. Part 3 specifies the release procedure for standards documents:

• Definition of “release”: clarifying what constitutes a C-ITS standards “release”;
• Release procedure: the release flow, triggers, and coordination mechanisms;
• Release management: ensuring version consistency and traceability across the parts of a standard.

4. Engineering Practice Applications 🛠️

• 📝 Standards writing: when writing national, industry, or enterprise C-ITS standards, use Part 1 to unify terminology, Part 2 to standardise document structure, and Part 3 to manage version release.
• 🔧 System development: in connected-vehicle (V2X) product and roadside unit (RSU) development, use unified terminology and standards structure as the basis to ensure interoperability with other vendors and systems.
• 📋 Project management: in C-ITS demonstration projects and pilot construction, use release procedures to manage the versioning of technical specifications and interface documents, ensuring consistency in multi-vendor integration.
• 🤝 Cross-domain coordination: C-ITS spans transport, communications, automotive, and information security; use this series as the methodological basis for cross-domain standards coordination.
