Full title and description

Intelligent transport systems — Cooperative ITS — Part 4: Minimum system requirements and behaviour for core systems. This Technical Report identifies potential critical minimum system requirements and expected behaviour for core (central) systems that support Cooperative Intelligent Transport Systems (C-ITS) service provision, and describes strategies to identify, control, limit or mitigate related issues. It is informative and does not provide prescriptive technical solutions.

Abstract

ISO/TR 17427-4:2015 raises awareness of system-level risks and constraints that C-ITS core systems may introduce or face, and points to subject areas and existing standards where specifications for some aspects can be found. The report outlines minimum considerations and recommended behaviours for core systems to improve interoperability, resilience and safe service provision, but does not itself specify detailed technical solutions.

Scope

The report is an informative C-ITS deliverable intended to identify potential critical minimum system requirements and expected behaviour for core systems (central infrastructure and service platforms) used to deliver cooperative ITS services. It considers how core systems might affect service provision, lists possible system-level issues (for example interoperability, security, privacy, availability and operator responsibilities), and describes strategies to identify, control, limit or mitigate those issues. It provides pointers to existing standards and subject areas where specification work exists but does not set normative technical requirements.

Key topics and requirements

• Identification of minimum system-level considerations for C-ITS core systems (availability, scalability, interoperability, security and privacy).
• Recommended behaviours for core systems to reduce operational and service risks.
• Strategies for identifying, controlling, limiting or mitigating critical issues introduced by C-ITS service provision.
• Guidance on roles and responsibilities associated with core-system operation (interfaces with other C-ITS actors).
• Pointers to related standards and normative documents for specific technical specifications (protocols, data models, security frameworks).
• Non‑prescriptive, informative content intended to raise awareness rather than mandate solutions.

Typical use and users

Used by C-ITS system architects, service providers, infrastructure operators, ITS programme managers, system integrators, procurement teams, certification and compliance bodies, and researchers. It helps planners and designers understand systemic risks and baseline behaviours expected of central/core systems when specifying, deploying or operating cooperative ITS services.

Related standards

Part of the ISO 17427 C-ITS family and ISO/TC 204 work on Cooperative ITS. Closely related items include ISO 17427-1 (Roles and responsibilities — published 2018) and other Technical Reports in the series such as ISO/TR 17427-2:2015 (Framework overview), ISO/TR 17427-3:2015 (Concept of operations for core systems), ISO/TR 17427-7:2015 (Privacy aspects) and ISO/TR 17427-10:2015 (Driver distraction and information display). Implementers typically consult these parts together to cover organizational, operational and technical aspects of C-ITS deployments.

FAQ

Q: What is this standard?

A: ISO/TR 17427-4:2015 is an informative Technical Report in the ISO 17427 series that identifies minimum system considerations and expected behaviours for core systems used to provide Cooperative Intelligent Transport Systems (C-ITS) services.

Q: What does it cover?

A: It covers high-level, system-level issues and recommended behaviours for C-ITS core systems — availability, scalability, interoperability, security, privacy and operational responsibilities — and suggests strategies to identify and mitigate related risks. It does not provide prescriptive technical specifications.

Q: Who typically uses it?

A: System architects, C-ITS service providers, infrastructure operators, procurement and programme teams, integrators, and researchers who need to understand baseline system behaviours and risks when planning, specifying or operating C-ITS core services.

Q: Is it current or superseded?

A: ISO/TR 17427-4 was published as Edition 1 in 2015 and is listed as published. Users should check national adoption or more recent ISO publications for updates; related work in the ISO 17427 family (for example ISO 17427-1) was published subsequently (2018) covering related topics.

Q: Is it part of a series?

A: Yes. It is part of the ISO 17427 series on Cooperative ITS (C-ITS) developed by ISO/TC 204; the series includes framework, ConOps, roles/responsibilities and topic-specific Technical Reports.

Q: What are the key keywords?

A: C-ITS, cooperative intelligent transport systems, core systems, minimum system requirements, system behaviour, interoperability, availability, security, privacy, ConOps.
