Safe Road Trains for the Environment (SARTRE) is a European Commission-funded project to investigate and trial technologies and strategies for the safe platooning of road vehicles, a transportation concept in which several vehicles are electronically linked together in a "road train", with only the lead driver in active control. The three-year project was launched in 2009. The research and development was carried out by several European auto manufactures with Volvo at the lead. A first practical test successfully took place in December 2010. In September Volvo announced that the SARTRE research project had come to a close, and that the company was ready to look into putting its finished product on the road.[1]
