Arizona State University (ASU) engineers have come up with an algorithm that manages autonomous vehicle traffic through intersections safely, under real-life conditions.

Developed by researchers in ASU's Make Programming Simple Laboratory, the robust and resilient intersection management (R2IM) algorithm deals with scenarios in which any car can start accelerating or braking at any time relative to traversing an intersection.

ASU's Mohammad Khayatian said, "Our approach uses a surveillance system, such as cameras mounted at an intersection, that can detect if a vehicle is not following its expected trajectory beyond a tolerance limit. If that's the case, the intersection manager declares that vehicle as 'rogue,'" then alerts all approaching vehicles so they react accordingly.
