Our approach for Infrastructure-aided Cooperative Driving bases on platooning. We define platooning as spontaneous and dynamic forming of convoys of vehicles, so called platoons. Each vehicle drives within a short distance to the next vehicle. This enables slipstream effects and fuel saving. Vehicles need to be driven autonomously or at least support the driver in holding the distance and keeping the vehicle within the lane boundaries, which reduces the likeliness of accidents. Drivers do not have to control forming of platoons as this is done automatically by the Platooning Coordination System (PCS). It receives information from drivers as their goal or route characteristics (e.g., if they want to go the shortest route, fastest route, or most efficient route) through the V2I interface. This information is used for finding an existing platoon or forming a new one. The PCS sends the information to the involved vehicles. Platooning is controlled by the vehicles via V2V communication. Overtaking of platoons is coordinated with the PCS and with other platoons.
