Truck Platooning is the future of transportation in which trucks drive cooperatively at less than 1 second apart made possible by automated driving technology. Transportation companies benefit from lower fuel consumption and improvements in (driver) productivity, while society benefits from fewer accidents, safer traffic and less congested roads, and lower carbon emissions. In this TNO whitepaper, we explain what platooning is, what kind of benefits it brings for which parties in the supply chain, and the roadmap towards deployment of platooning on Dutch and European roads.
