Thomas Gotschi, formerly of the Rails-to-Trails Conservancy, presented a cost-benefit analysis of bike infrastructure and promotion in the city of Portland, Oregon.

Since 1991, Portland has spent $64 million on bicycling paths, lanes, and programs. There are a lot of people reaping the benefits of bicycling there now, but it won’t be until 2017 that enough has been saved on health care and fuel for the city to recoup its investment.
