CEN ISO/TS 21184:2021

This document 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 modelto 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.
