The goal of OneBusAway is to improve the usability of public transit. To help achieve that goal, we provide a number of open-source tools and applications to help transit agencies, riders, and developers work with public transit systems.

This wiki on github is the home for developer-related content for the OneBusAway project. Please see the OneBusAway project home page for information for transit agencies, project vision statement, high-level development agenda, research projects and publications, and a description of project governance.

For Agencies and Users wanting to run OneBusAway—Technical Information
