“We need a new signal called blue phase, meaning you should follow the vehicle in front of you,” says civil engineer and traffic control researcher Ali Hajbabaie.

Yeah, a bunch of cars that all follow each other, with signals set up so they don't have to stop! Imagine if you could get on a roadway in one place and go straight through to the next pla... Wait this is a train.

Why do these carbrains keep re-inventing trains, but shittier?

@aaronbieber Timed lights work fairly well on SLC’s commuter roads. The train idea depends on drivers with wildly different reaction times. I’d rather take a bus & light rail.

@stevewfolds Granted!

The researcher I cited is talking about a signal that says "follow the car in front of you because there are AI-driven ones that are handling things," and I think once you are at a level of throughput where we need AI to negotiate flow, maybe there ought to be a light rail.

Doesn't SLC have a really nice light rail system? I never rode it when I was there but it seemed quite modern.

@aaronbieber Yes. Light rail was part of the infrastructure for the 2002 Winter Olympics and much expanded since. $1.25 for a senior to go downtown and back via bus to rail.
