The Economic Impact of Bicycling and Walking As economic recession has impacted communities across the nation, active transportation has emerged as a promising sector for growth and revitalization. Bicycling and walking projects create 11-14 jobs per $1 million spent, compared to just 7 jobs created per $1 million spent on highway projects. A series of case studies in 2010, examining the construction of U.S. bicycle and pedestrian facilities, found that such projects created between 218 and 1,050 new construction jobs.
After an initial economic boost from construction, pedestrian and bicycle infrastructure has a lasting impact on local economies. A 2009 study in Minnesota found that bicyclists on state trails spend $2.4 billion annually, supporting nearly 31,000 full- and part-time jobs. A survey of San Francisco business owners on Valencia Street found that two-thirds of merchants thought the street's bike lanes had an overall positive impact on their business or sales.
Bicycling and walking also results in significant cost savings on health care spending. If just one out of every 10 adults started a regular walking program, the U.S. could save $5.6 billion in health care costs — enough to pay the college tuition of more than 1 million students. Thanks to bicycle infrastructure and programming, the City of Portland expects to see between $388 and $594 million in health savings by 2040. Cost benefit analysis show that as much as $11.80 in benefits can be gained from every $1 invested in bicycling and walking.
