Platooning may be the new way of travelling on motorways in as little as ten years time – and the EU-financed SARTRE project has carried out the first successful demonstration of its technology at the Volvo Proving Ground close to Gothenburg, Sweden. This is the first time the EU-financed development teams in SARTRE try their systems together outside the simulators. Platooning offers the prospect of improved road safety, better road space utilisation, improved driver comfort on long journeys and reduced fuel consumption and hence CO2 emissions. With the combined skills of its participating companies, SARTRE is making tangible progress towards the realisation of safe and effective road train technology. Vehicle platooning, as envisaged by the SARTRE project, is a convoy of vehicles where a professional driver in a lead vehicle drives a line of other vehicles. Each car measures the distance, speed and direction and adjusts to the car in front. The tests carried out included a lead vehicle and single following car. The steering wheel of the following car moves by itself as the vehicle smoothly follows the lead truck around the country road test track. The driver is able to drink coffee or read a paper, using neither hand nor foot to operate his vehicle. Platooning is designed to improve a number of things: Firstly road safety, since it minimises the human factor that is the cause of at least 80 percent of the road accidents. Secondly, it saves fuel consumption and thus CO2 emissions with up to 20 percent. It is also convenient for the driver because it frees up time for other matters than driving. And since the vehicles will travel in highway speed with only a few meters gap, platooning may also relieve traffic congestion.
