Our mission is to provide you with data and resources that help you have informed, constructive conversations with your elected officials and hold them accountable to the unsafe conditions on our city streets.

Transpo Maps was created by Stephen Braitsch
in April, 2022. Stephen has been fighting for safer streets and sustainable transportation since he moved to San Francisco in 2008. In 2019 he designed and built Safe Lanes
, an app that makes it effortless to report drivers for illegal parking and in 2020 he launched The Bike Match Network
which has connected over 300 essential workers with free bikes during the pandemic. Stephen has volunteered countless hours with pedestrian and cyclist advocacy organizations across the Bay Area and beyond and has served on the Board of Directors of the San Francisco Bicycle Coalition.
