Environmental Benefits of Vehicle Platooning
Safe Road Trains for the Environment (SARTRE), a research project funded by the European Commission under the Seventh Framework Programme, has developed the technology and the strategy to create fully functional road trains that allow vehicle platoons to operate in public highways. The project intends to establish important concepts to show why platooning systems are a good way to increase safety and reduce pollution on tomorrow's highways. As part of the activities within the project, the authors performed fuel consumption simulations to estimate the fuel consumption reduction of the platoon due to the aerodynamics improvement. Dynamic simulations of the platoon behaviour in certain normal and emergency situations were also performed. Fuel consumption tests were also performed in companies proving grounds. These tests were performed using two trucks and three cars. Different platoon configurations were used, involving some or all the vehicles.
