The General Bikeshare Feed Specification, known as GBFS, is the open data standard for shared mobility. GBFS makes real-time data feeds in a uniform format publicly available online, with an emphasis on findability. GBFS is intended to make information publicly available online; therefore information that is personally identifiable is not currently and will not become part of the core specification.GBFS was created in 2014 by Mitch Vars with collaboration from public, private sector and non-profit shared mobility system owners and operators, application developers, and technology vendors. Michael Frumin, Jesse Chan-Norris and others made significant contributions of time and expertise toward the development of v1.0 on behalf of Motivate International LLC (now Lyft). The North American Bikeshare Association’s endorsement, support, and hosting was key to its success starting in 2015. In 2019, NABSA chose MobilityData to govern and facilitate the improvement of GBFS. MobilityData hosts a GBFS Resource Center and a public GBFS Slack channel - you are welcome to contact us there or at sharedmobility@mobilitydata.org with questions.GBFS is intended as a specification for real-time, read-only data - any data being written back into individual shared mobility systems are excluded from this spec.The specification has been designed with the following concepts in mind:Provide the status of the system at this momentDo not provide information whose primary purpose is historicalThe data in the specification contained in this document is intended for consumption by clients intending to provide real-time (or semi-real-time) transit advice and is designed as such. https://github.com/MobilityData/gbfs
