System-to-car communication and slightly more complicated street lights would be enough. I disagree, I'd say scheduling is the smallest part of it. On most trips I take, there's a single major road that covers most of the distance, and I'm most likely to be delayed by traffic on that road slowing or halting completely. It's the moment-to-moment perverse behavior of other drivers when it comes to merging, changing lanes, accelerating and braking that causes that to happen, and having intelligent drivers on the same roads at the same times would make a much more significant impact. In other words, you're saying we could do global scheduling with traffic lights, which is true. I'm saying that with sufficiently competent drivers we won't need the lights, and I think that will cause a qualitative shift in the nature of traffic.
