Drew these schematics the other day. Was thinking mostly about Scottsdale Road, near where I live. So many cars, not a lot of people, completely exposed to the scorching heat. There are some meagre trees and some more details and nuance but I just drew the height and width in an average.
These drawings below (from 1920s journal Planificacion) by Architect Carlos Contreras were where I got the dimensions for the world cities I included. There are other studies of transverse sections out there, interesting to think about.
