City of San Francisco 2009 Bicycle Count Report
In August 2006, the SFMTA Bicycle Program conducted its first citywide bicycle count, with the goal of establishing a baseline of bicycling use around the City. Over the past three years, the SFMTA has continued with bicycle counts in the first three weeks of August. The data gathered from the last four years have enabled the SFMTA to identify and measure some basic trends in bicyclist ridership throughout San Francisco. Furthermore, the bicycle counts will inform the City's ongoing bicycle planning efforts, providing the data needed to evaluate the efficacy and efficiency of the City's bicycle network, as well as identifying locations where additional infrastructure improvements are needed.
