‘Urban canyons’ can cause signal blackouts in driverless cars

As motor firms continue to develop their autonomous vehicle technology, the safety of driverless cars has been dragged into the spotlight as expert fear they could experience signal blackouts in built-up cities.

Autonomous cars require a GPS signal in order to identify where other autonomous vehicles are around them.

However, ‘urban canyons’ caused by high-rise towers and skyscrapers on either side of a road can block signals received from satellites and result in ‘potential safety and operational implications’, according to a global leader in autonomous vehicle software.

Urban canyons are formed when a street is densely populated by tall buildings on both sides.
