The General Transit Feed Specification (GTFS) has revolutionized multi-modal information and open transit data. Started as a simple way to represent fixed route transit systems by TriMet in Portland, Oregon and Google in 2005, GTFS data is now shared publicly by over 1,500 transit agencies worldwide, according to Transitland.
There are exciting new developments in the world of bike share that could potentially mirror the success of the GTFS data format. The General Bikeshare Feed Specification (GBFS) was launched by the North American Bikeshare Association (NABSA) in 2016 as a standardized way for apps to access information about the availability and location of rental bikes, as well as the capacity of racks where bikes can be returned.
This Google Summer of Code project will help accelerate the adoption and utilization of the GBFS format by implementing open-source tools to consume the data format and visualize it in an existing open-source transportation app:
