Those numbers fail to place bicycling and walking into the bigger overall picture. Yes, 46.5 billion combined trips is a lot, but how does that compare to trips made by car? Well, back in 1994, 7.9 percent of all travel trips were made either on foot or while seated on the bike's saddle. By 2009, that number shot up to 11.9 percent.
The initial study back in 1994 found that walking and biking had major benefits. The report identified these five categories as primary reasons for turning to non-motorized transportation: better health, increased transportation efficiency, environmental benefits, economic benefits and improving the quality of life. Remarkably, 15 years later, these benefits continue to convince us to walk or bike as much as we can. Additionally, these same benefits are now the driving force behind the advanced technology vehicles of tomorrow.
