Benefits

There are no doubts about the potential benefits of C2X communication technology but so far those benefits cannot be quantified because there are no field trials with cooperative systems technology ongoing yet that can provide the data needed for a serious assessment of the benefits. During the course of DRIVE C2X a number of test sites for cooperative systems are operated, providing this data in order to verify the rough guesses about potential benefits with respect to

  • safety
  • efficiency
  • sustainability and
  • convenience.

Safety and efficiency impacts are supposed to be the most significant ones but sustainability and convenience effects should not be neglected. Sustainability effects of C2X communication will become an issue more and more because of emission laws getting more and more stringent and asking for new technological means for emission reduction. Convenience aspects are also very relevant because cooperative systems enable new convenience functions for all stakeholders in road traffic, which might be the key to implementation of this technology. It is expected, that attractive commercial applications provide a revenue source to re-finance the investments into this technology by OEMs and infrastructure operators.

Since detailed knowledge about the impacts of cooperative systems technology is crucial for all stakeholders for taking an implementation decision there is a need for a thorough analysis of the impact of cooperative systems on European level. Dedicated methods and tools for the analysis of the technological economic and safety and efficiency related aspects of C2X communication technology have been developed and piloted in PRE-DRIVE C2X. The methods applied for evaluation of human factors aspects are coming from projects such as eImpact, FESTA, EuroFOT or TeleFOT. The methods and tools to be applied in DRIVE C2X are described in detail in the chapter Driving.
