Today is Winter Bike To Work Day in Chicago at Federal Plaza. If the results below are true, we should hold this event weekly during the winter! Held on January 20th to celebrate the coldest temperature on record, in 1985.

I was looking for research on why more people don’t ride bikes, or why they don’t ride bikes more often. I started my search on Professor John Pucher’s website at Rutgers University and found this about Bike To Work Days and other promotional events.

There is some evidence that BWDs increase bicycling beyond the event. The number of “first time riders” has increased in many programs: in Seattle, from 845 new commuters in 2004 to 2474 in 2008; in Portland, from 433 in 2002 to 2869 in 2008 (LAB, 2008). In San Francisco in 2008, bicycle counts at a central point were 100% higher on BWD and 25.4% higher several weeks later; bicycle share was 48.3% before BWD, 64.1% on BWD, and 51.8% afterwards (LAB, 2008). In Victoria, Australia, 27% of first time riders on BWD were still bicycling to work 5 months later (Rose and Marfurt, 2007).

Read it on page 8 of this PDF. I thank John for distributing all of his work for free online so that those without expensive journal subscriptions (or those who lost it by graduating college) can read the latest in bicycle research.

Here’s me surveying an attendee at the 2009 Bike To Work Day Rally in Chicago’s Daley Plaza. The results of the surveys taken each year by the Chicago Department of Transportation are not published.
