This app is free and open source. It was created to promote public transportation in order to help fight global warming and reduce our dependency on oil. OpenMBTA is part of a new green software movement that calls on developers to donate their time to making free and useful software that helps us save the environment and promote democracy.


The idea for this mobile app was born during Open Government Hack Day at Betahouse in Central Square, Cambridge, MA on September 27, 2009.

Chris Dempsey and Joshua Robin of the Massachusetts Department of Transportation were tremendous sources of encouragement and answered lots of questions. They pushed the MBTA to open up its data and make apps like this possible.

Michael Smith of NextBus helped OpenMBTA access real-time bus data.

Eric Richmond helped create the mobile web interface for OpenMBTA.

Braulio Carreno also provided this project with useful insights into the GTFS dataset.

Hoony Youn created the Android client for OpenMBTA.

Daniel Choi created that iOS clients and the Ruby/PostgreSQL back end.

OpenMBTA is maintained by Kaja Software, a software company based in Cambridge, Massachusetts.
