EuroFOT (European Field Operational Test) was a FP7 project which ran from 2008 to 2012. The project involved over one thousand cars and trucks that were equipped with existing advanced driver assistance systems. They travelled European roads during one year. The potential to both enhance safety and reduce environmental impact was evaluated. EuroFOT also revealed a link between these systems and improvements in driver behaviour, fuel efficiency and traffic safety, as well as overall cost savings.
