scope:

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 and the correct interpretation of data. This document defines standardized data classes in a Global Transport Data Format (GTDF), and the means to manage them. Data exchange between ITS stations is based on messages and content composed of pre-configured information, including conditional handling. Each message uses a global unique identifier and the associated data element. The format of the data element is specified by the global unique identifier pointing to configuration information including instructions for correct interpretation of the data element. Application and role-based access control to GTDF resources are specified in accordance to IEEE 1609.2 certificates. This document specifies GTDM as an ITS-S capability which conforms to ISO 24102-6, which is an optional feature. The GT access control (GTAC) data model specifies permission to protocol services and data parameter access based on assigned roles. The GT function monitor (GTFM) data model specifies function bricks and data concatenated to a monitoring logic by the GTFM configuration data. It is possible to implement the Open Telematics Platform/Open Vehicular Secure Platform as introduced by the European commission (see OVERSEE[10]) as an ITS Station Unit.
