Vision Zero Benchmarking: Separated Bike Lanes
City streets with separated bike lanes as of 2022 for San Francisco and 9 peer cities.
Controller's OfficeWhy separated bike lanes matter
Bicycling is one of the many ways people travel throughout a city. People biking can be vulnerable to cars if they are sharing the lane or in an exposed area. Separated bike lanes reduce that risk. Parked cars, posts, islands or other physical barriers separate bicyclists from traffic.

Data notes and sources
To create this dashboard, we searched for the miles of separated bike lanes in our peer cities. Only those shown here reported the total miles of separated bike lanes. We then normalized that by the miles of road in the city. We found the data from individual city sources:
There are several different classifications of bike lanes. We focused on separated bike lanes, one of the safest options for travelers. To learn more about the different types of bike lanes, review the SFMTA's website.
Many cities are building more separated bike lanes. San Francisco plans to continue building separated bike lanes through the Quick-Build Program, Biking and Rolling Plan, and other transportation safety projects.

Key takeaways
San Francisco has one of the highest rates of separated bike lanes. SF's rates are similar to New York's, with about 3% of streets having separated bike lanes.
