OneBusAway is an open-source software system that implements a real-time transit information system using the GTFS data specification for the basic description of the transit system. OneBusAway was initially developed in 2008 by Brian Ferris and Kari Watkinsat the University of Washington and saw its initial deployment in the Puget Sound area in Washington. Since its initial deployment OneBusAway has since been deployed to other cities including Atlanta, San Diego, Tampa, Washington, D.C., with international deployments in York (Canada), Finland, and Poland. 
In 2013, the MTA in New York City implemented OneBusAway software as a core part of its Bus Time system. \cite{Ferris_2010,transitwiki2017}
