Navigating a roundabout or traffic circle is hard for humans and for AI self-driving cars

Help, I am stuck in a roundabout and I can’t get out!

For those of you that have ever driven into a roundabout, often also known as a traffic circle, a road circle, and sometimes a rotary, they can be devilish to navigate.

Typically, a novice driver finds them to be frightening and a real-world version of a crazy bumper-car mad dash. Seasoned drivers like to think that they have mastered the roundabout and so act like it is a breeze to traverse one. Even seasoned drivers are at times though thrown for a loop, as it were, and find themselves baffled and frustrated by a roundabout. If you get enough drivers going through a roundabout and if they are all behaving badly, you find yourself wishing you had gone some other path and had avoided the dreaded roundabout.

At the Cybernetics AI Self-Driving Car Institute, we’ve been developing techniques and software to enable AI self-driving driverless cars to properly traverse a roundabout.

Most of today’s self-driving cars hand the driving back to the human driver when encountering a roundabout. That’s if the self-driving car even realizes that a roundabout is about to occur or occurring.
