Bicycle Infrastructure = More Bicyclists
"Based on figures from an annual count of bicyclists conducted since 1984, the New York City Department of Transportation announced on Thursday that commuter cycling rose a remarkable 35 percent between 2007 and 2008.
The data are suggestive, not definitive, but officials said they considered the trend to be genuine.
The annual count, known as a screenline count, was first conducted in 1980 and has been done annually since 1984. This year's count identified 12,583, up from 9,327 in the previous year."
