ISO/TS 21184:2021 specifies a global transport data management (GTDM) framework composed of

— global transport basic data model,

— global transport access control data model,

— global transport function monitor data model, and

— sensor and control network data model

to support data exchange between applications.

This document defines standardized data classes in a Global Transport Data Format (GTDF), and the means to manage them.

Application and role-based access control to resources in GTDF are specified in accordance with IEEE 1609.2 certificates.

This document specifies GTDM as an ITS-S capability which is an optional feature (ITS-capabilities are specified in ISO 24102-6).

The GT access control (GTAC) data model specifies access permissions to data and function control by defining role-based mechanisms.

The GT function monitor (GTFM) data model specifies a configuration method to generate a flow logic for monitoring purposes, e.g. observing data parameters with respect of a defined limit.
