Quiet safe urban areas actually exists in large amounts of Germany, while the only real urban areas that exist in the USA are in SF and NYC.  SF &amp; NYC have a sizable homeless population, poop on the streets and similar with large amounts of traffic.  Suburban city centers attract the homeless and have a large amount of traffic because everyone has to drive in.<p>German urban areas tend to barely have any road traffic for the density since almost nobody owns a car, a quiet train that passes by once in a while and most things closing at 8pm latest.  Need some medicine?  The pharmacy is a 5 minute walk away.  Board the metro in another 5 minute walk, get to work in 20m.   There are barely any homeless or poop on the streets for the most part because they are actually put in social housing and programs (or jail) if the police find them doing that.<p>You tend to have about 10 square miles of urban area, with 7 story buildings as far as the eye can see and then a sudden drop off into small villages that are everywhere.  You can rent or buy large 5 room 2000sqft apartments in these places and actually raise the typical 2.5 kid household in them. In the center of the block there are little common parks with a playground for small kids to play.<p>If you want your car and SFH lifestyle, the entire city is then surrounded by wooded areas with small villages that are everywhere.  You can live in a small village and drive into work into the city about 30m away for fairly cheap.  The villages themselves have small urban centers you can then walk into. And some of them have trains, so you can just take the train into the city if you want.<p>My experience is only with Germany, but I&#x27;m guessing there are many other places such as Barcelona, Italy or the UK that is designed like this.
