Question 1

Where does transportation and commute data come from?

Accepted Answer

Commute patterns come from the Census Bureau's American Community Survey. Transit route data comes from GTFS (General Transit Feed Specification) published by transit agencies. Bridge condition data comes from the Federal Highway Administration's National Bridge Inventory.

Question 2

What do bridge condition ratings mean?

Accepted Answer

Bridges are rated on a scale from 0-9 for their deck, superstructure, and substructure. A rating of 7+ is 'Good,' 5-6 is 'Fair,' and 4 or below is 'Poor.' A 'Poor' rating does not mean unsafe, as bridges are closed or weight-restricted before becoming dangerous, but it indicates a need for significant repair or replacement.

Question 3

What is the average commute time based on?

Accepted Answer

Average commute time is based on self-reported data from the American Community Survey. It represents the typical one-way travel time from home to work for employed residents, including all modes of transportation. It does not include people who work from home.
