Description (English):

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 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.

Abstract

Overview

CEN ISO/TS 21184:2021 - also published as ISO/TS 21184:2021 - defines a Global Transport Data Management (GTDM) framework for Cooperative Intelligent Transport Systems (C-ITS). The specification standardizes how transport-related data is modeled, managed and exchanged between applications and ITS-S (ITS Station) components. GTDM defines a Global Transport Data Format (GTDF) with standardized data classes, plus mechanisms for managing access, monitoring functions and optional sensor & control network (SCN) integration.

Keywords: C-ITS, GTDM, GTDF, ITS-S, global transport data management, ISO/TS 21184:2021.

Key topics and technical requirements

Global data models: The framework is composed of four core data models:
- Global transport basic data model (GT basic) - structure and runtime/configuration for transport data.
- Global transport access control (GTAC) data model - role-based access permissions and authorization constructs.
- Global transport function monitor (GTFM) data model - configuration constructs to generate monitoring flow logic (e.g., parameter limit checks).
- Sensor and Control Network (SCN) data model (optional) - for integrating vehicle networks and ECU addressing.
Global Transport Data Format (GTDF): Defines standardized data classes and packaging for consistent data exchange.
Access control & security:
- Role-based mechanisms (GTAC) specify permission sets and control of data and functions.
- Certificate-based access is specified in accordance with IEEE 1609.2 certificates.
- GTDM is specified as an optional ITS-S capability (ITS-capabilities referenced per ISO 24102-6).
Use-case coverage: Designed for proximity (V2X), on‑board, and remote ITS applications, plus configuration authoring and management.
Management & facilities: Defines ITS-S roles (e.g., Configuration Provider, Data Provider, SCN Handler, GTP Handler, Function Monitor) and startup/management behaviors.

Applications and who uses it

Vehicle OEMs & Tier‑1 suppliers: Standardize in-vehicle data models, secure access to vehicle data, diagnostic and ECU interfaces.
ITS application developers: Build interoperable services that read/write GTDF data across vehicles, infrastructure and cloud.
Road operators & traffic authorities: Integrate vehicle-sourced data into traffic management, incident detection and fleet operations.
Cybersecurity architects & system integrators: Implement certificate-based role access and conform to ITS-S capability models.
Aftermarket and telematics providers: Use GTDF for standardized telemetry, remote diagnostics and over-the-air configuration.

Keywords: GTAC, GTFM, GTDF, IEEE 1609.2, ITS-S capability, V2X, vehicle data exchange.

Related standards

ISO 24102-6 - ITS-S capabilities (reference for optional GTDM capability)
IEEE 1609.2 - certificate formats and security for access control
ISO/TS 21177 - secure sessions for ITS (referenced in GTDM security clauses)

This specification supports interoperable, secure, role-based transport data exchange across vehicle, roadside and remote ITS ecosystems.
