The data for this visualization comes from the American Community Survey which is conducted by the U.S. Census Bureau. I used the Census Bureau API to pull the 2015 1 year estimate for the mean commute time in each state. Once I had gathered the data, I used Tableau to create this visualization.
Update: We got a lot of feedback that people would like to see this data at a lower geographic level, so we made a new visualization that shows it on a county level.
