Putting it all together

Footnotes

  1. Using San Francisco as a guide, the average population per square mile is a little over 18,000. However, most neighborhoods have higher population densities.
  2. I’m assuming a block length of 350 feet and street widths of 60 feet, using San Francisco as a guide once again.
  3. Americans don’t seem to walk much at all.
  4. It also implies that over half of the neighborhood’s residents are walking at any given time, which sounds less reasonable.
  5. I originally tried a naive equation of 1-.988³⁶⁵ but it didn’t match my (most likely more accurate) simulation. In the meantime I’m going to look into a better way to model this distribution.
  6. Remember this number only includes residents.
