How many bicyclists are there in Oakland? Has the number increased over time, and if so, by how much? Are there parts of the city with more bicyclists than other parts? To help answer these questions, Oakland Public Works monitors volumes of bicyclists in a number of ways:
Annual Counts Program
Oakland Public Works launched an annual program in Fall 2011 to count the number bicyclists at judiciously chosen locations. The purpose is to create consistent data long term on city-wide bicycle usage. Counts are collected at 36 intersections. For details see intersection map, list, and counts methodology.

Analysis of Census Data
An adjunct to the US Census is the American Community Survey (ACS, www.census.gov/programs-surveys/acs). The ACS is conducted more frequently than the Census and asks more detailed questions. One of the topic areas is on transportation including primary commute mode to work. This data point is useful for analyzing where bike commuters live. RespondentsÕ answers to this ACS question are widely assumed to undercount bicyclists (because it includes only the primary commute mode by length thus excluding, for example, many bike trips to BART). Still, it is the primary way communities throughout the nation are able to analyze travel trends.

Oakland has collected traffic counts for decades. Over the last several years, volunteers have created an online interactive map showing intersection locations with available counts (bicyclist, pedestrian and/or vehicle) and a summary of the count data. The map, which includes summary data for over 2,000 traffic counts (as of January 2016) is at www.oaklandbikemaps.info/counts. Raw data: www.oaklandbikemaps.info/counts/reports/counts.7z
