Watch a Self-Driving Car Obey Police Hand Signals

Palm Reading

For autonomous vehicles that rely on smooth roads and clear signals, a broken traffic light could conceivably pose a major problem.

To get around the problem of a missing green light, self-driving car company Waymo trained its vehicles’ artificial intelligence to detect and respond to the arm movements of a traffic cop as they wave traffic through an intersection, according to CNET — and you can watch it on YouTube.

Long Time Coming

Waymo first claimed that its autonomous vehicles could respond to hand signals from nearby cyclists back in 2016. That particular research treated cyclists, from the vehicle’s perspective, as obstacles to track and avoid.

A new video published by Waymo on Wednesday is the first that shows its vehicles responding to gesture commands — especially in the absence of the traffic lights on which it would normally rely — and obeying police orders. The video, which runs at three times normal speed, shows a picture-in-picture display of the car’s digital perspective and a video camera as it goes through an intersection.
