Although only a few driverless cars are even in testing mode, researchers are already considering how to rework traffic intersections to integrate the computerized vehicles.
Four driverless cars approach a four-way stop: how will they decide who has the right of way without waving their hands and flashing their lights?
According to Peter Stone, a computer scientist at the University of Texas at Austin, such interactions will completely disappear. Furthermore, traffic regulation will become even more streamlined as more driverless cars hit the road. Even complicated intersections, such as traffic lights, will have finely-tuned control to keep traffic moving and prevent collisions.
"[W]e won’t need traffic lights at all (or stop signs, for that matter)," wrote Emily Badger at The Atlantic Cities of his work. "Traffic will constantly flow, and at a rate that would probably unnerve the average human driver."
Stone has modeled how driverless cars progressing down a 12-lane road would move through an intersection, with each vehicle tracking the others to create the optimal movement with no human interception. You can watch the animation here:
The yellow cars in the animation are human-piloted vehicles -- which of course raises the question of how to actually integrate people, including cyclists and pedestrians, into the picture. All the cars will be tracked wirelessly, of course; will people and cyclists additionally require wireless tags for tracking? Badger wrote:
Those human-driven cars would have to wait for a signal that would be optimized based on what everyone else is doing. And the same would be true of pedestrians and bike riders. Stone says the system is designed to have flexibility under the assumption not all decisions would be made by computers alone.

Maybe they can get these microchip cars able to drive with people, but what happens when one of them hits my car because I did something the programming didn't expect? Too much liability, lawyers and politicians (who are also just lawyers) will kill this idea in America. And widespread adoption will never occur due to cost. I can get a fairly reliable vehicle on the road for 3-5 thousand dollars. How much will a PC car cost? I'm just too cheap to blow that much money on transportation. Put our efforts into something useful, this will not work any time soon.
The ITS Initiative Main Flaw The future of automated freight delivery and personal transportation is neither a delivery truck nor a car, the Intelligent Transportation Systems (ITS) initiative main flaw is assuming it will! Why is anyone trying to figure out how to make a truck and a car drive themselves after they are designed and built to be driven? I suppose the reason is that we already have the vehicles and the roads; but, has anyone considered developing and implementing a fully automated freight delivery and personal transportation system using vehicles no one has to drive from the start? I did and submitted a U.S. Patent Application for it. You can go to my blog to read more about it: http://theitsinitiativemainflaw.blogspot.com/ Thanks, ALBERTO ZAYAS
Notice in the video how none of the cars stop because the technology allows for them to be woven seamlessly into each other. With current technology, GPS, cars that automatically park - We have embarked into a inovative new world. Lets step carefully, morally, with faith and logic.
