Webinar: Spatial Equity Analysis of Dock-based and Dockless Bike Share in San Francisco

Event Date


Event Overview

Bike share use has grown rapidly over the past decade, and is rebounding from ridership declines in the early days of the COVID-19 pandemic. Both dock-based and dockless bike share systems can improve urban mobility and provide an alternative to car travel, supporting cities’ safety, livability, and sustainability efforts. But actors such as bike distribution, cost, and lack of payment options can limit certain communities’ access these benefits.

This webinar will present findings from a quantitative analysis comparing the service levels of dock-based and dockless bike share systems operating in San Francisco with respect to underserved communities. The analysis is based on multiple advanced metrics: the spatial distribution of service areas, available bikes and bike idle times, trip data, and rebalancing among dock-based and dockless systems. The analysis finds that the dockless bike share system’s larger service area and frequent bike rebalancing practices result in greater availability of bikes in underserved communities. These results can provide policy insights to local municipalities regarding managing bike share systems to improve equity.

Guest Respondent

drian LeungAdrian Leung works at the San Francisco Municipal Transportation Agency as Bikeshare and Bike Parking Program Manager. He's worked in bike/ped planning and advocacy since 2004, at non-profits, private firms, and public agencies. He was the first to call Donald Shoup “Shoup Dogg,” and he feels fortunate to be working on efforts explicitly around mode shift. He likes to think of imagining the future as a kind of time travel to alternate realities. He's seen how the alternate realities of soft shared mobility range from fantastic to frightening.
