ISO/TS 19468:2022 PDF

Overview

ISO/TS 19468:2022 - Intelligent transport systems - Platform-independent model specifications for data exchange protocols - defines a platform-independent framework for exchanging and sharing data among centres that manage transport information and control. The Technical Specification focuses on the component facets required for data exchange between Traffic Information Centres (TICs), Traffic Control / Traffic Management Centres (TCCs/TMCs) and Service Providers (SPs) (and can be applied to other actors such as car park operators). ISO/TS 19468:2022 is restricted to data exchange modeling and does not define payload content models or the technical interoperability domains themselves.

Key topics and technical requirements

• Platform-independent models (PIMs): Abstract protocol elements and UML-based modeling for exchange patterns so implementations can be mapped to different technical platforms.
• Exchange modeling framework: Business scenarios, functional exchange profiles, requirements, features and exchange patterns (e.g., snapshot pull, snapshot push, simple push, stateful push, simple CIS).
• Exchange data model: Informational structures, relationships, roles, attributes and associated data types required for exchanges.
• Exchange features: Subscription contracts, session management, information management, data delivery semantics, self-description and communication considerations.
• Use cases and requirements: Scenarios and feature sets tailored to different exchange situations and service types.
• Abstract elements for protocols: Message definitions and state diagrams to support consistent implementations.
• Constraints: Definition of interoperability domains (plug-and-play technical interoperability) and payload content models are out of scope; see related standards (for example, the ISO 14827 series) for technical platform definitions.

Practical applications and who uses it

ISO/TS 19468:2022 is practical for organizations designing interoperable ITS data exchanges:

• Traffic authorities and TMCs/TICs implementing standardized interfaces for sharing situational data and control messages.
• Service providers (map, traffic, fleet management, parking) integrating with centre-to-centre data interfaces.
• System architects and integrators creating protocol mappings from PIMs to concrete technical platforms (HTTP/REST, MQTT, DATEX II bindings, etc.).
• Vendors and platform developers who need UML-based models and exchange patterns to ensure consistent behavior across deployments.

Benefits include clearer data interface design, reduced integration effort, and a blueprint to achieve interoperable transport information and control systems when PIMs are bound to a chosen technical platform.

Related standards

• ISO 14827 series (examples of defining interoperability domains and technical protocol bindings).
• Other ITS standards and specifications for payload/content models (payload definitions are outside ISO/TS 19468:2022 scope).
