Convoys of semi-autonomous trucks are expected to be tested on public roads in the UK before the end of next year, the government announced today. The Department for Transport and Highways England have rustled up £8.1 million in funding between them to pass on to the Transport Research Laboratory (TRL), the independent organisation that'll conduct the trials. TRL will start with simulation studies and driver training before moving onto a test track and finally, public roads by the end of 2018. Platooning, as it's known, is one of the simpler ways of harnessing self-driving technology. While the truck at the front of a convoy remains under human control, trailing vehicles follow its lead autonomously.
