Seattle's 2009 Downtown Bicycle Count Results

According to the SDOT, there are more bicycle commuters headed to Downtown Seattle than in previous years, a 15% increase since 2007 when the counts were last done.

In addition to pretty charts, the web page has a lot of interesting stats listed, such as:
Percentage increase since since 2000: 28%

Number of bicyclists wearing a helmet in 1992: 71%

Number of bicyclists wearing a helmet in 2000: 82%

Number of bicyclists wearing a helmet in 2007: 89%

Number of miles cycled yearly by average bike commuter: 1,992

I learned about this data being available from a posting on the PI web site.
