Mixed Use

Density

There is a strong correlation between density and walking, cycling and transit use in a community.

5 7 105 minutes is the average threshold for walking

7 minute transit frequency is when users no longer need to consult a schedule

10 units per acres is the minimum amount of density to support frequent transit service
