They will have to attend a few conferences in Paris and Dubai first also.

AI mobility management has the opportunity to make moving around easier for lots of people. But...
This poster nailed it, at peak times the issue is always volume, access and choke points in the system, and that will always be the case. Using a BR example, even if Essen was 5 lanes each way you would still have back-ups at major intersections and where you enter/exit I-10. Also accounting for driveways is always a challenge on city streets,
The other potential benefit of autonomous vehicles is safety, but that will also mean slower speeds since AI will prioritize safety over speed, as it should.

The issue is development and volume. I have watched AI modeling address and intersection in Baton Rouge. It is awesome as long as it is not looking at rush hour ties because it answers always comes back with volume is too heavy to optimize.

Yea theres no fixing that. Im not a computer or a cloud and i know that. Optimization outside of rush hour is where the big gains are.

Optimization usually means telling people to merge onto the freeway faster. The Cane Island on ramp on I-10 in Katy causes multi-mile backups multiple times a day, 7 days a week because people get on the interstate doing 35. The on ramp is plenty sufficient to hit at least 60.

That would be amazing. They can't even do a semi-reasonable job of syncing lights here in Knoxville. From a traffic management position, I don't know if there is a bigger clusterfrick in the country than the Cedar Bluff exit.

Hate to break it to you guys, but the powers that be prefer the lights not be synchronized / optimized. This leads to to “congestion” which is then used to push through more money to “fix” congestion.
Back in the early 90’s the city of Austin was essentially unsynchronizing the traffic lights to create inefficient traffic flow to push mass transit of some sort.

With all the crap AI still gets wrong, you want it controlling intersections with chunks of metal hurtling towards each other at up to 50 mph?

No matter what Austin did then, it was still subject to two things: White liberal women going slower to be "safe" in many areas of town, and illegals knowing they won't get pulled over for anything. Any town constricted by a river is at a disadvantage, but Austin and Baton Rouge are butt brothers. Somehow, Texas built a loop around Austin, but Baton Rouge
