My organization, Rails-to-Trails Conservancy, recently released a report, "Active Transportation for America," which quantifies for the first time ever the benefits our nation would realize with increased walking and biking ("active transportation"). The report documents the transportation, energy, climate, public health, and economic benefits of bicycling and walking. Among our findings, we noted that increases in walking and bicycling could lead to between 70 and 200 billion reduced miles driven annually, potentially saving Americans more than $65 billion annually. We released the report to Congressman James Oberstar (D-Minn.) a few weeks ago, calling on Congress to take action in the next transportation bill to provide greater resources for walking and biking.
