I recently watched a video [1] about the planned cities built by the Soviets and it all seems really nice. One advantage in their case is that they planned industrial activity as well so they built residences within bicycling distance from factories (with green space in between) so people could get to home, shops, and work with a walk or bike ride.
Actually I remember that Japan has done a lot of industrial planning too, but I don’t know if they paired that with residential and commercial spaces. Something to look in to. (Please comment if you know.)
