ITS reference architecture for traffic information in private transport

The ITS reference architecture for traffic information in private transport concretizes the ITS architecture framework Germany (RIAD) for the ITS service category traffic information in private transport.

The subject of the ITS reference architecture for traffic information in private transport is all on-trip traffic information directly affecting road users, independent of the communication medium. This includes, for example, information transmitted via radio communication (broadcast radio, WLAN, mobile radio, etc.) to the end devices of road users, including C2X, as well as information on dynamic signage.

The ITS architecture procedure model – based on the TOGAF (The Open Group Architecture Framework) architecture development method – is used for the development of the ITS reference architecture according to the ITS architecture framework Germany.

The following phases are taken:

1. Preliminary Phase
2. Phase A: Architecture Vision
3. Phase B: Business Architecture
4. Phase C: Information System Architecture consisting of Data Architecture and Application Architecture

In the Preliminary Phase the integration of underlying models is clarified and model adaptations and important principles for architectural development are defined. In phase A the objectives of the architectural development are determined. The results of phases B and C represent the core ITS architecture. Phase B describes the current and desired state of the Business Architecture. The differences are worked out and documented, among other things, with the help of business process diagrams. Phase C describes the current and desired state of the Data and Application Architecture.

Each phase is divided into several steps. This ensures a methodical and comprehensive approach in the development of an ITS architecture.
