Did you ever wonder how our streets got to be so unsuitable for anything but driving cars? One guy who has figured it out is Dan Burden, who a couple of decades ago served as bicycle-pedestrian coordinator in the state Department of Transportation. Streetsblog interviewed Burden about a new set of guidelines that should help cities and states be smarter about how they build and redesign streets. It's good reading. Pay attention to what he says about street widths, then look again at the discussion here earlier about the pending upgrade of Sunset Drive outside South Miami.
To learn more about Dan's thinking, watch his talk to the Commonwealth Club in San Diego.
