People Protected Bike Lanes (PPBL) is a bicycle demonstration tactic that originated in San Francisco in 2017, in which participants stand on the street in line, along a painted bike lane, to draw attention to its inadequacy. The following study tracks the global expansion of PPBL, which as of the close of 2023 has occurred in 25 cities in 11 different countries.

Below is a database which catalogs different People Protected Bike Lane demonstrations, their location, size, and subsequent installation of protected bike lanes. If you participated in or have documentation of a PPBL demonstration which is not included in this database, please contact via my NYU email.
