(Reuters) – Ford Motor Co and Virginia Tech Transportation Institute are testing a way to enable self-driving vehicles to communicate their movements visually to pedestrians, cyclists and to human drivers, the researchers said on Wednesday.
The new communications method, which uses simple light signals to depict whether a self-driving vehicle is slowing or accelerating, has the potential to become a universal industry standard in all countries, Ford and VTTI researchers said.
The automaker set out to find “a way to replace the head nod or hand wave” to convey to pedestrians the intent of a driverless vehicle, according to John Shutko, Ford’s human factors technical specialist.
Researchers rejected the use of displayed text because of potential language barriers, and symbols because of their low recognition.
Instead, they settled on visual signals from a light bar placed on the windshield of a Ford Transit Van. A solid white light shows the vehicle is in full autonomous…
