The US DOT recently presented Congress with an interim report on the progress of the Nonmotorized Transportation Pilot Program. The report reveals that eastern Marin residents walk and bike 13.6% (compared to the national average of 9.5%). In eastern Marin alone, this increase in walking and biking trips means:

• 43.3 billion fewer car miles each year (or 131,000 miles each day)
• A savings of more than $8.3 million in fuel costs
• A reduction of 20,932 metric tons of carbon dioxide emissions

Marin County Supervisor Steve Kinsey notes that, "This program, and its legacy, will change the face of transportation in communities across the country. Its contribution, and that of walking and bicycling, to the nation's fight against global warming will be notable."

The full report is available here. A Marin IJ article covering Marin-specific highlights is available here.

Update (3/18/08): The Twin Cities Times published an article on the interim report as well.
