Evolving the European Its Architecture for Car-to-x Communication

With the publication of a first framework of the communications architecture for European Intelligent Transport Systems (ITS), a major milestone was achieved in harmonization of various R&D efforts towards a unified architecture. Relying on this framework, the project PRE-DRIVE C2X further elaborates four main aspects of the ITS communications architecture: (i) overall system architecture, (ii) network architecture, (iii) integration of ad hoc, infrastructure and backend services, and (iv) security architecture. This paper presents the main aspects of the architecture views and gives an outlook to further developments of the architecture, standardization, and deployment in future Field Operational Tests of cooperative
