PD CEN ISO TS 19468-2022 PDF

Full title and description

PD CEN ISO/TS 19468:2022 — Intelligent transport systems — Data interfaces between centres for transport information and control systems — Platform‑independent model specifications for data exchange protocols for transport information and control systems. This document (CEN/ISO Technical Specification) defines platform‑independent model (PIM) specifications to support exchange and shared use of traffic and travel data between traffic information centres, traffic/traffic management centres and service providers.

Abstract

This Technical Specification specifies component facets for data exchange framework, data content and structure, relationships and communications specifications that are independent of any specific technical platform. It establishes functional exchange profiles, abstract protocol elements and an exchange data model to enable interoperable exchanges between Traffic Information Centres (TICs), Traffic Control/Traffic Management Centres (TCCs/TMCs) and Service Providers (SPs). Payload content models and definition of interoperability domains are out of scope.

Scope

This Technical Specification defines platform‑independent model (PIM) specifications for data interfaces between centres for transport information and control systems. It covers use cases and requirements for exchange situations, functional exchange profiles, abstract protocol elements and an exchange data model (informational structures, roles, attributes and data types) required for interoperable data exchange between TICs, TMCs and service providers. It is restricted to data exchange; payload content models and definition of technical interoperability domains are explicitly out of scope.

Key topics and requirements

• Exchange modelling framework: business scenarios, use cases and requirements to guide interoperable exchanges.
• Functional exchange profiles: predefined profiles mapping use cases to exchange patterns and constraints.
• Exchange patterns and message lifecycle: snapshot pull/push and simple push patterns with message definitions and state considerations.
• Abstract protocol elements (PIM): protocol‑level abstractions to enable translation to platform‑specific implementations (PIM → PSM).
• Exchange data model: informational structures, relationships, roles, attributes and data types required for interoperability.
• Operational features: subscriptions/contracts, session handling, delivery semantics, self‑description and communication/optimization considerations.
• Platform independence: specifies logical exchange requirements without mandating transport, encoding or payload content models.

Typical use and users

Used to design and implement interoperable centre‑to‑centre data interfaces in ITS. Typical users include traffic and transport authorities, traffic information and traffic/traffic management centre architects, ITS integrators and middleware vendors, mobility and traffic service providers, municipalities and transport operators, and platform or data‑broker vendors building cross‑centre exchange solutions. The specification is a blueprint for mapping use cases to concrete protocol implementations.

Related standards

ISO/TS 19468 is commonly used together with platform‑specific or profile standards that define concrete encodings and transport bindings (for example the ISO 14827 series and parts of the EN/ISO DATEX family). Implementers typically map the PIM in ISO/TS 19468 to platform‑specific messages in ISO 14827 and related ITS exchange profiles.

FAQ

Q: What is this standard?

A: It is ISO/TS 19468:2022 (adopted as PD CEN ISO/TS 19468:2022 in the CEN context) — a technical specification that defines platform‑independent model specifications for data interfaces between centres in ITS.

Q: What does it cover?

A: It covers the logical framework for centre‑to‑centre data exchanges: use cases, functional exchange profiles, abstract protocol elements, an exchange data model and operational features (subscriptions, sessions, delivery semantics). It does not define payload content models or specific transport/encoding implementations.

Q: Who typically uses it?

A: Traffic authorities, TICs/TMCs, ITS system architects, integrators, software vendors, service providers and municipal/transport operators who need interoperable centre‑to‑centre data exchange.

Q: Is it current or superseded?

A: The document is published as Edition 2 (2022) and replaced the 2019 edition; it is currently published and subject to the usual ISO review cycle. Implementers should check their national body or the ISO catalogue for any later amendments or revisions.

Q: Is it part of a series?

A: Yes — ISO/TS 19468 provides a platform‑independent model that is intended to be mapped to platform‑specific standards and profiles (for example the ISO 14827 series and DATEX‑related profiles) to produce concrete encodings and transport bindings.

Q: What are the key keywords?

A: Intelligent transport systems, data interfaces, platform‑independent model (PIM), exchange protocols, traffic information centre, traffic management centre, functional exchange profile, subscription, session, interoperability.
