Evaluating user acceptance of C2X systems by focus group discussions

This paper presents the results of discussions held in focus groups formed by test users of the 7th Framework Integrated Project DRIVE C2X (DRIVing implementation and Evaluation of C2X communication technology in Europe) at five test sites. The focus group discussions aimed at finding out the user reported benefits and drawbacks of the cooperative systems after the actual field tests with the systems. The acceptance of the systems and their interfaces, their benefits and usefulness and the drivers' willingness to pay for the systems were evaluated. In addition, possible annoyances of the current DRIVE C2X functions perceived by the users were identified. In general, the users were satisfied with the systems and valued their potential in the future. They thought that most of the functions could in their mature state be helpful in increasing traffic safety and driving comfort. However, the drivers also raised some concerns with the current systems and provided valuable input for improvement.
