Overview
ISO/TR 25102:2008 - Intelligent transport systems - System architecture - “Use Case” pro‑forma template - provides guidance and a standardized pro‑forma for writing use cases applied to software‑intensive intelligent transport systems (ITS). The Technical Report defines the purpose and structure of a use‑case template, explains its role in requirements elicitation and system architecture work, and recommends a consistent approach (using UML where appropriate) for ITS International Standards and related deliverables. The guidance is informative rather than prescriptive: template elements may be augmented or omitted as needed.
Keywords: ISO/TR 25102:2008, Intelligent transport systems, use case template, ITS, UML, system architecture, requirements.
Key topics
ISO/TR 25102:2008 covers the following technical topics and recommended use‑case elements:
- Purpose and rationale for using use cases in ITS requirements and architecture work
- UML as a consistent modeling approach (not mandatory)
- Use‑case elements and structure, including:
- Title, description, scope, level and target system release
- Primary actor, stakeholders/participants and related actors
- Triggers, pre‑conditions, post‑conditions and assumptions
- Scenarios (normal and alternate), expected outcomes and exceptions
- Acceptance criteria, business rules, technology restrictions
- Relationships (includes, extends), inclusions and extensions
- Verification approach, test cases, references to requirements
- Versioning, modification history, approvals, open issues, application notes
- Guidance on how to apply and adapt the pro‑forma for different ITS deliverables
- Benefits for requirements management: improved consistency, stakeholder understanding, and traceability between use cases and requirements
Applications
ISO/TR 25102:2008 is practical for organizations and roles involved in ITS system design, requirements and standards work:
- Systems architects creating ITS system architecture and interfaces
- Requirements engineers who need structured, verifiable requirement definitions tied to user goals
- Standards writers and technical committees (e.g., ISO/TC 204 WG1) aligning use‑case artifacts across standards
- Project managers, test engineers, and developers who use use cases to derive test cases, acceptance criteria and implementation scope
- Stakeholders and suppliers needing a common template to achieve consensus and consistent documentation
Using this template supports clearer communication across multidisciplinary ITS projects and helps link high‑level architecture to verifiable system requirements.
