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 (ISO/TS 19468:2019)

This document defines and specifies component facets supporting the exchange and shared use of data and information in the field of traffic and travel.
The component facets include the framework and context for exchanges, the data content, structure and relationships necessary and the communications specification, in such a way that they are independent from any defined technical platform.
This document establishes specifications for data exchange between any two instances of the following actors:
— Traffic Information Centres (TIC);
— Traffic Control Centres/Traffic Management Centres (TCC/TMC);
— Service Providers (SP).
This document can be applied for use by other actors, e.g. car park operators.
This document includes the following types of information:
— the use cases and associated requirements, and features relative to different exchange situations;
— the different functional exchange profiles;
— the abstract elements for protocols;
— the data model for exchange (informational structures, relationships, roles, attributes and associated data types required).
In order to set up a new technical exchange framework, it is necessary to associate one functional exchange profile with a technical platform providing an interoperability domain where plug-and-play interoperability at technical level can be expected. The definition of such interoperability domains is not part of this document but can be found in other standards or technical specifications, e.g. ISO 14827‑3. This document is restricted to data exchange. Definition of payload content models is beyond the scope of this document.

Systèmes de transport intelligents - Interface de données entre centres pour les systèmes de commande et d'information des transports - Spécification du modèle indépendant de plateforme pour les protocoles d'échange de données pour les systèmes de commande et d'information des transports (ISO/TS 19468:2019)

Inteligentni transportni sistemi - Podatkovni vmesnik med prometnimi informacijskimi centri in kontrolnimi sistemi - Specifikacija modela za neodvisne platforme za protokole izmenjave podatkov za prometne informacijske in kontrolne sisteme (ISO/TS 19468:2019)

Področje uporabe te tehnične specifikacije je določitev in opredelitev vidikov v zvezi s komponentami, ki omogočajo izmenjavo in skupno uporabo prometnih ter potovalnih podatkov in sporočil. Komponente vključujejo okvir in kontekst za izmenjave, podatkovne vsebine, strukturo in razmerja ter komunikacijske specifikacije, tako da so neodvisne od katere koli definirane tehnične platforme. Ta tehnična specifikacija določa specifikacije za izmenjavo podatkov med katerima koli akterjema na naslednjem seznamu:
– prometni informacijski centri (TIC),
– prometni nadzorni centri/centri za upravljanje prometa (TCC/TMC),
– ponudniki storitev (SP),
ne omejeno na druge akterje, npr. upravljavce parkirišč ...
To tehnično specifikacijo lahko uporabijo tudi drugi akterji.
Ta tehnična specifikacija vključuje naslednje vrste informacij:
– primere uporabe in z njimi povezane zahteve ter značilnosti v zvezi z različnimi situacijami izmenjave,
– različne profile funkcionalne izmenjave,
– abstraktne elemente za protokole,
– podatkovne modele za izmenjavo (potrebne informacijske strukture, razmerja, vloge, atribute in z njimi povezane vrste podatkov).

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.
