Drive C2X – The FP7 project, completed in 2014, provided a comprehensive, Europe-wide assessment of cooperative systems through field operational tests. The field trials involving seven test sites all across Europe proved the safety and efficiency benefits of cooperative systems. More than 750 drivers successfully tested eight safety-related functions of cooperative systems. Technically the systems tested showed faultless performance during the extensive field trials in seven European countries. User acceptance evaluations, safety and efficiency benefits, and business studies were also undertaken for the functions.
