The Federal Highway Administration has just released urban highway statistics for 2015, including the miles of roads and daily vehicle miles of driving by road type and “selected characteristics” for each urban area, including population, land area, freeway lane miles, and similar information. These data are quite useful as they allow interregional comparisons as well as, when combined with past data, a look at trends over time.

For example, the Los Angeles urban area is more than twice as dense as the Houston urban area, yet both report the same number of miles of driving per capita (see population note below). Though there is a weak correlation between density and driving, it isn’t as strong or as certain as urban planners would like you to believe.

As published by the FHwA, each table of more than 400 urban areas is divided into nine worksheets of 50 urban areas. Since this is clumsy, I’ve copied-and-pasted them into one worksheet each, which you can download for the miles of roads and selected characteristics. Continue reading
