A first of its kind report in the Journal of Physical Activity and Health finds that Portland, Oregon's past and planned investments in bicycling relate to millions of dollars saved in health care costs and fuel expenditures (.pdf). By 2040, the author states that investments in the range of $138 to $605 million will result in health care cost savings of $388 to $594 million and fuel savings of $143 to $218 million. The League of American Bicyclists shares additional data from the Portland metropolitan region, showing that investments in biking and walking are related to more new commute trips in bicycling – and at a lower cost – than investments in motor vehicle infrastructure.

The Cost Effectiveness of Active Transportation Investments


Around here we love data, so after I sent the latest safety in numbers data around the office, it took Andy less than an hour to try to one-up me. He passed along this graph showing the Portland Metropolitan Region’s expenditures on biking and walking, transit, and motor vehicles (1995 – 2010) along side the number of new daily commute trips by those modes (1990 – 2008). There were increases in the number of commuters for all three modes. What the graph makes clear is how cost-effective the biking and walking investments were. The city spent about 11 times the amount on motor vehicle infrastructure that they spent on active transportation per new commuter.

Portland Regional Expenditures and New Trips

[Updated, Feb 18th.] “In 2008, Portland had 14,912 more daily bicycle commuters, 13,191 more daily transit commuters and 37,0006 more drive alone commuters than in 1990,” explains Portland’s Bicycle Coordinator, Roger Geller,  ”During that time period bicycling  grew appreciably compared to population. Drive alone trips dropped, from 67.3% to 64.6%, transit trips grew 18% from 11.4% to 13.4% and bicycling grew 440% from 1.2% to 6.4%.”

Here are the graphs separated out:

Portland Increase in daily commute trips 1990 - 2008

Portland Regional Capitol Expenditures 1995 - 2010

Hopefully, you can read the graph at the top. If not, I’m happy to email it. (Request it at darren [at] bikeleague.org.) The blue bar is the total expenditures (1995 – 2010). The red bar is the increase in daily Portland commute trips (1990 – 2008).  The black line towards the bottom is the estimated cost of complete Portland’s 2030 Bicycle Master Plan.

Thanks to Roger Geller for sending us these graphs.
