I'm an engineer so I love graphics. This one is brilliant. It was not done by me and I am ashamed to say that I can't locate the author in my inbox to properly credit them, but this represents a perfect understanding of transportation infrastructure.
Let's contrast the wisdom of that graphic with the standard approach of the engineering profession. The following graphic is from the master plan for Lander, WY, but a derivation of it is likely found in your own local plan or transportation guideline. This thinking is ubiquitous.
The current engineering approach is to balance access and mobility. The result is a stroad, the futon of transportation providing poor access along with limited mobility (and does it at great financial cost).
A Strong Town appoach understands that the greatest value is created by transportation investments that focus on access OR mobility. If you want to build a strong town, stop building stoads.
