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.
