The SFMTA monitors bicycle volumes and commute trends citywide through three data collection methods: ACS Commute Data, annual bike counts collected manually at specified locations and automated counters citywide. One year ACS Commute Data displays the most recent bike volume trends for bike mode share citywide. Since 2006 the SFMTA has conducted annual bicycle counts at intersections during the evening peak period in the second week of September to analyze bike volume trends at the same locations annually. Lastly, we have counters throughout the city that continuously collect bike volume data. This data is collected and analyzed together to help inform policy and planning decisions as the agency works towards implementing more complete street designs citywide.

Average Weekday Bike Volumes Dashboard
This graph displays the average weekday bike volumes for counters by location. The average weekday volume for each counter is calculated using the specific number of weekdays that counters were up for at each location.
*This dashboard uses data from our 39 consistently reporting counters from 2018 onward.
-
Annual Bike Comparison by Month
This dashboard displays monthly bike volumes for our consistently operating counters. Some counter locations have changed and counter installation dates vary, resulting in some variation in reporting.
*Data prior to 2018 is pulled from 74 counters. From 2018 on, data is pulled from 39 counters.
-
Hourly Bike Counts
This dashboard displays hourly bike volumes for our consistently operating counters. Some counter locations have changed and counter installation dates vary, resulting in some variation in reporting.
*Data prior to 2018 is pulled from 74 counters. From 2018 on, data is pulled from 39 counters.
DISCLAIMER: Our counters embedded in the pavement are typically within the bicycle facility. As a result of this we are not able to capture riders who are outside of the facility. Data is drawn from days that counters were active, meaning that counters may have been active on different days. Although automated counter installation dates vary, no data precedes January 2016.
AUTOMATED BIKE COUNTER LOCATION MAP
Spatial data for our automated counter network can be found on DataSF, here.
*We are in the process of updating the spatial data to reflect the newly consolidated automated counter network as of 10/25/2024
