Overview

CEN ISO/TR 21186-1:2021 (ISO/TR 21186-1:2021) provides guidelines on the standardization landscape and releases for Cooperative Intelligent Transport Systems (C-ITS). This Technical Report maps global standardization activities by major Standards Development Organizations (SDOs), explains the purposes and categories of SDO deliverables, describes how C-ITS services are presented and performed, and defines an approach for creating C-ITS Releases. It also includes a bibliography of standards with special relevance to C-ITS.

Key topics

• Standardization landscape
  • Overview of global SDO activity relevant to C-ITS and ITS.
  • Roles of SDOs and relationship with regulatory requirements.
• Goals of standardization
  • Enabling technical interoperability, portability, syntactic and semantic data interoperability, minimum functionality and performance, and reliable protected operations (privacy and cyber security).
• Classification of SDO deliverables
  • Introduces a scheme to classify different types of standards and technical documents.
• C-ITS services and service provisioning
  • Methods for presenting and performing services, including:
    • Broadcast-based information dissemination
    • Service announcement mechanisms
    • Services initiated by central stations
  • Use-case-driven approach to service description and provisioning.
• Releases and release management
  • Concept and management of C-ITS Releases (consistent sets of standards and parameter profiles).
  • Examples and exemplification (including a referenced “C-ITS Release 2” and standards clustering).
• Bibliography
  • Curated list of standards with special relevance to C-ITS deployments.

Practical applications and target users

This document is intended for stakeholders involved in planning, developing, deploying, and regulating C-ITS solutions:

• System architects and ITS application developers - choosing appropriate standards and release profiles for interoperable products.
• Vehicle and equipment manufacturers - aligning implementations with standardized interfaces and release profiles.
• City planners and transport operators - selecting interoperable C-ITS services to improve safety, efficiency, comfort and sustainability.
• Standards bodies and consortia - coordinating release definitions and profiling activities.
• Regulators and procurement teams - understanding standard types and how releases support compliance and market fairness.
• Security and privacy specialists - aligning protection measures with release requirements.
