Impact assessment of cooperative systems in the DRIVE C2X Project

This paper presents the impact assessment of the Cooperative Intelligent Transport Systems piloted in the 7th Framework Program project DRIVE C2X. In this project, eight cooperative systems were developed and evaluated in Field Operational Tests (FOTs). This paper presents the methodology used in the impact assessment of the eight systems in the areas of safety, traffic efficiency, and environment and mobility impacts, at the European level. The DRIVE C2X functions, which mostly targeted safety impacts, achieved safety improvements but with some adverse effects on traffic efficiency and slight positive effects on fuel consumption and CO2 for the environment. On reflection, greater impacts could have been achieved if traffic and human factors specialists had been involved in the system design and prototype phases
