The Case for Active Transportation, by the Numbers

Snapshot_2008_10_24_11_21_59.jpgThanks to commenter Stephen for prodding us to post on the new report from the Rails-to-Trails Conservancy, "Active Transportation for America" (download the PDF here).

What
makes the report notable are the numbers it contains. It’s jam-packed
with quantifiable benefits that would result from increased investment
in infrastructure that encourages and supports pedestrians and
cyclists.

For instance, the report’s authors write:

  • Increasing
    the bicycle and pedestrian share of trips of one mile or less from
    currently 31 percent to 40 percent under a Modest Scenario, and to 70
    percent under a Substantial scenario, would result in 28 billion or 49
    billion miles driven avoided, respectively.
  • Modest
    increases in bicycling and walking for short trips could provide enough
    exercise for 50 million inactive Americans to meet recommended activity
    levels, erasing a sizeable chunk of America’s activity deficit.
  • For
    the price of a single mile of a four-lane urban highway, approximately
    $50 million, hundreds of miles of bicycle and pedestrian infrastructure
    can be built, an investment that could complete an entire network of
    active transportation facilities for a mid-sized city.
  • The
    financial value of improved mobility, fuel savings, greenhouse gas
    reductions, and health care savings amounts to more than $10 billion
    annually under our Modest Scenario. For the Substantial Scenario,
    benefits would add up to more than $65 billion every year. These
    benefits dwarf historic spending for bicycling and walking, which was
    $453 million per year for 2005–2007 under SAFETEA-LU, and a mere $4.5
    billion cumulative federal investment in these modes since 1992, when
    bicycling and walking first received documentable federal funding.

Metro’s $40 Billion Plan

Metro’s Plans Are Big on Expansion, Not So Big on Increasing Bike/Ped. Access to Their Stations Before Metro can place a half cent sales tax increase on the fall ballot, it needs to tell us how it’s going to spend the $40 billion the increase would raise over the next thirty years.  At last week’s […]
