Traditionally, roads were inspected by hand to identify cracks and potholes. Now, #AI is helping us do this faster and more accurately while saving money.

It would be nice to see this 2014 "Handbook for Designing Roadways for the Aging Population" updated with more bicycle-related content highways.dot.gov/sites/fhwa.d...
But that feels unlikely with the current admin
I also wonder if an @trb.org NCHRP effort would make sense first

Check out this table in the Supplemental Information (static-content.springer.com/esm/art%3A10...), it lists all kinds of nature-based solutions for climate resilience. You could print it out & bring it parties this weekend to refer to. "What do you do for fun?" [unrolls this table] "I like nature".
