Future Vehicle Intersections May Ditch Stoplights

Automated cars would call ahead and schedule a time for the intersection
Some major technology firms see the future of the automobile as a much more automated device that can navigate on its own without a driver. There are, however, differing visions of what those automated vehicles of the future may look like.
Google sees those
as needing no driver and being standalone with sensors and GPS capability to successfully navigate the roads that we have today without human interaction. Others see a more automated type of vehicle where the intersections and roads themselves tell the vehicles when and where to go.
A computer scientist working at the University of Texas at Austin named Peter Stone is working on technology that will help fully automated vehicles reduce traffic and navigate intersections safely. Stone believes that future intersections won’t need stoplights or stop signs. Instead, a virtual traffic controller that schedules when the vehicle stops and when it starts would manage automated vehicles.
"A future where sitting in the backseat of the car reading our newspaper while it drives us effortlessly through city streets and intersections is not that far away," says Stone, a professor of computer science at The University of Texas at Austin.
Stone is creating AI computer systems that will allow the autonomous vehicles to call ahead and reserve a space and a time at the intersection. An automated intersection manager would then approve the request and the vehicle and move through the intersection during its allotted time. The idea is that by scheduling these automated vehicles in such a way, there will be very little stopped traffic reducing traffic jams and allowing for faster transportation between two places.
"Computers can already fly a passenger jet much like a trained human pilot, but people still face the dangerous task of driving automobiles," Stone says. "Vehicles are being developed that will be able to handle most of the driving tasks themselves. But once autonomous vehicles become popular, we need to coordinate those vehicles on the streets."

but there is no single entity/program/thingy taking control of multiple aircraft.

I brought up the aircraft thing because of probability. You're mentioning a "what if" worst case scenario without giving any reason to believe it could happen or even that it's likely (or, really, even that it's possible).
It's possible that 1 million people commuting to work tomorrow will have seizures and crash their cars. Pretty unlikely, but it could happen...

Ok, here's likely scenario for you.
They use Windows boxes and every xx number of days the system shuts down and has to reboot. Hope everyone is awake and near the controls of their cars.
Or, think of it as Google going down. It doesn't happen often but it affects a lot of people when it does. Fortunately, if you wait a few seconds for the mirror/backup to take over you are off and running again. If you don't get the proper scheduling for an intersection, that's a problem.
