Rails to Trails Study...

Pro-biking data from Rails to Trails for use as needed:

The analysis concludes that
modest increases in bicycling and walking could lead to an annual
reduction of 70 billion miles of automobile travel. More substantial
increases could lead to the avoidance of 200 billion miles per year
(see textbox on page 5).
This volume of decreased auto travel is equivalent to cutting oil
dependence and greenhouse gas emissions from passenger vehicles
by 3 percent (Modest Scenario) to 8 percent (Substantial Scenario).
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.
