Bristol robot experts have helped create and launch what is being heralded as one of the most ambitious and complex trials of driverless, autonomous bus systems in the world.
The trial, involving a team from Bristol Robotics, based at the University of the West of England, has put buses that drive themselves on a park and ride bus route that crosses the Forth Bridge and heads in and out of Edinburgh.
The 14-mile route taken by the buses include the Forth Road Bridge, A-roads, motorways, bus lanes, traffic lights and roundabouts. There is a driver on board, sitting behind the wheel - this is a trial - but the aim is to show that the technology will allow the bus to drive, steer, manoeuvre and navigate through traffic itself.
