In the demo pics there are radial/circular subdivisions. I find this odd, given that it's supposed to be an "American-style" generator. I've personally never seen any american city that has radial subdivisions.




There are circles in cities, but not (to my knowledge) circular sub-divisions as depicted on the site. That's something I associate with Europe, not America.

In most of America, including Washington D.C., the circles are very quickly ironed back out into grids.


What about some of these retirement communities like Sun City, Arizona: https://www.google.com/maps/place/Sun+City,+AZ/@33.6291865,-...


Gotta say that design is pretty cool looking. I like how they put a golf course on the perimeter!


I'd chalk it up there with the "deigners" who draw swoopy lines for parking lots that look great on a map and are a nightmare to use.


Well-found! I had no idea those existed, but they do seem to fit the radial nature of the procedural designs.

Of course, they're much, much, much less dense than the designs, but the generator is still neat. Just not very "American-style" IMO.

These look pretty cosy.


This site claims to create American-style cities, but includes images with radial circles that extend about seven blocks, which is not at all something most people associate with American cities, but do associate with, say, Spain.

The urban density in these images is also more commonly found in Europe than America.

Which is fine! It's a generator for European-style cities, and it's neat! But so far, only low-density western desert cities have anything like 7-ringed wedges like this, and I suspect that most people, like me, didn't know those existed there before this thread.

There's plenty of them in the western edge of Las Vegas.


Those are just traffic circles with some spokes.

The generated maps show concentric circles, which is super-unusual in the US. I don't think I've seen it anywhere.

I'm actually curious if it's a common pattern in some other country.


Not very similar. Those DC "circles" just crosscut a rectangular array. The area itself does not appear radial.


DC is modeled after the square and compass symbols

Gotcha. It was the only city that immediately came to my mind as at least having circles embedded in it.



> What's it all about? No one knows what Woodward was really thinking, but with the geometrical mania that blossomed with the birth of the United States, it should not be surprising to find a backwoods judge thinking along the same lines as architects of the Italian Renaissance.

Is this sarcasm? Am I being wooshed? The street plan is the same obvious Masonic imagery that's on the back of every Federal Reserve Note. Take a look at the incredibly beautiful Detroit Masonic Temple and imagine it as the "Eye" in the Eye of Providence that would have been the street layout:

https://en.wikipedia.org/wiki/Detroit_Masonic_Temple

And look where it is in Detroit compared to the tiny bit of the street plan that was implemented: https://www.google.com/maps/place/Masonic+Temple/@42.3351973...

Really cool; thanks for the link!


Boston (https://www.google.com/maps/@42.3591352,-71.06249,15.28z) is close to round. You don't get grids until you get out of the colonial era city.


These cities were originally part of the colonies of the British empire. So I would say they aren't necessarily completely "American". I'd look more central to western US cities to see how American style city planning is done.


What you have are different eras. Older is usually more chaotic. Look at New York below 14th St., then contrast with above which came later.

You can draw another line when car culture became common. Before then, it was grids accessible by streetcars. After, the cul de sac style and similar becomes common.


In my case, the peripheral road around a circular subdivision carries on into the river: https://imgur.com/a/173tCV3
