I look for development like what they had at the height of the pre-auto age. That usually was a downtown area with the offices and major department stores. There was a grid street system so there were many alternative routes for cyclists. Streetcar routes followed the grid pattern, and streetcars travelled on tracks in the middle of streets. Commuter trains radiated from the downtown station, facilitatinfg the development of suburbs within 30 minutes of the downtown. These suburbs each had their own mini-downtowns, much like a village or town. There were also shopping districts scattered throughout the city, so everybody was within walking distance of a grocery, bank, pharmacy, etc.
If you want to see what pre-car cities looked like, there are hundreds of views at
