Overview
ISO/TR 24529:2008 provides guidance on the use of the Unified Modelling Language (UML) in the development of International Standards, Technical Specifications and Technical Reports for Intelligent Transport Systems (ITS). Prepared by ISO/TC 204 WG1, the Technical Report discusses how UML can be applied to ITS systems architecture, the benefits and risks of adopting UML, and considerations for interoperability, model-driven development and ITS data registries.
Key topics
- Scope and purpose
- Guidance on applying UML within ITS standards, deliverables and documentation.
- Normative references
- Links to related standards such as ISO 14813 (reference architectures), ISO 14817 (ITS data registries), ISO/IEC 19501 (UML 1.4.2) and supporting TRs (for use cases and UML use in ITS).
- Definitions and architecture concepts
- Common ITS architecture terms (actor, logical/physical/system architecture, use case, model, reference architecture).
- Advantages and disadvantages of UML
- Advantages: internationally standardized notation, multiple viewpoints, tool and training ecosystem, support for metadata registries and MDD (model-driven development).
- Disadvantages: unfamiliar jargon for non‑software stakeholders, evolving standard (compatibility issues), and current limitations for full systems engineering coverage.
- Modelling considerations
- Need for multiple viewpoints and layered architectures for ITS.
- Importance of consistent formats to enable automation.
- Topics such as use cases, ITS data registries, UML profiles, modelling tools and the sufficiency of UML for ITS are discussed.
- Implications
- Recommendations on stakeholder acceptance, adoption of UML profiles, tool support and future-proofing models for interoperability.
Applications and who uses it
ISO/TR 24529 is a practical reference for:
- Standards developers producing ITS standards, specifications and TRs.
- Systems architects and engineers designing ITS logical and physical architectures.
- Software developers and tool vendors implementing UML models, transformations and model-driven development workflows.
- Procurement teams and project managers who need consistent architecture descriptions to ensure interoperability.
- Data registry maintainers aligning UML models with ITS/TICS data dictionaries and registries.
By encouraging consistent UML use, the report supports more automated, interoperable ITS specifications and clearer communication among stakeholders.
