This is not quite a spherical cow and there is something to be learned here, but really, I'd like to see this with
- non-square-grid cities with highways, public transport, …
- realistic synthetic populations doing non-random destination selection (nobody randomly goes to a supermarket at the other end of a city, after all)
- actual traffic simulation with jams (or at least using real traffic data)
and then evaluate both the energy use and travel times. That being said, doing this kind of thing, e.g. with ActivitySim, even for one real city, is quite a bit of work.

The reality is a lot depends on your economy. A manufacturing and port city will necessarily be very different urban form to a white collar office job city or a beach/lifestyle city full of remote workers. An egalitarian city will be very different from a socially segregated city. Etc.
Cities are also never perfectly efficient because they are always evolving in function and use

Google Maps has all that data.

You can look at small parts of it there. And sometimes you can't even buy what you're looking at, GMaps API won't hand out public transport trips in some countries. And where you can, it's fairly expensive. (No idea about traffic or people movement data.)
Excellent. I am looking for better strategies for Cities Skylines

Hexagons are bestagons
(apparently a city based on a hexagonal grid would be more efficient)

(has played sim city thousands of times since 1993) "I got this."

Just look at Magnasanti for the most efficient sim city

Without getting behind the paywall, the abstract says that how far you have to travel determines how far you have to travel??

I was going to dismiss this and then I read the whole abstract and that is, pretty much what it says. Oh but I guess it also says they came up with a model for how far apart things are determining how far you have to travel to get there

I forget that actual reference.
But there was an article or map or something talking about the placement of towns, I think, back east (or the south, or Virginia).
Simply, the towns were placed within a days travel of each other. And the communities they served were, effectively, about a 1/3rd days travel in radius. That's how far folks would go to get into town, and being a day apart facilitated long range travel instead of camping in the wilderness.
The towns were basically small towns designed to serve those local communities. Cities formed on the intersections of such roads to support more trade and traffic.
I don't recall if it talked about towns along rivers where transit might be faster.
But it was an interesting article with a map of actual towns.

I think the best shape for a city is a Mobius strip: go anywhere without turns, so no traffic lights needed.
