Based on the overall description of a common European architecture for an inter-vehicle and vehicle-to-infrastructure communication system PRE-DRIVE C2X developed a detailed system specification and a working as well as functionally verified prototype. It is robust enough to be used in future field operational trials of cooperative systems. Furthermore PRE-DRIVE C2X developed an integrated simulation model for cooperative systems, which, for the first time, enabled a holistic approach for estimation of the expected benefits in terms of safety, efficiency and environment.

This work was topped of by the development of tools and methods necessary for functional verification and testing of cooperative systems in laboratory environment, on test tracks and on real roads in the framework of a field operational test. These were applied to the PRE-DRIVE C2X prototype system to verify its proper functioning and to perform a limited impact assessment including a user-friendliness test. Last but not least extensive dissemination activities were carried out in order to communicate the benefits of cooperative systems vehicle technology to the public and to address all relevant European stakeholders.
