Wendell Cox has summarized the latest ACS report on commuting in America. He shows three years of data for the major travel modes, 2000, 2010 and 2011. Skip the one-year change and look at the eleven-year comparisons. The biggest loser has been car/vanpooling (all those diamond lanes have not helped). Bicycling is up, but from a very small base.
The biggest numerical gains are in drive-alone. "Getting people out their cars" continues to be a challenge.
Work-at-home is also up appreciably. That did not cost the public a lot in new infrastructure. No worries over "who built that."
