Online mapping pioneer MapQuest is using open data to provide transit directions via its MapQuest Directions API and the OpenStreetMap-based MapQuest Open Directions API. In both cases, transit directions are based on the Google-created GTFS data standard that helps transit agencies share their routes, schedules and fares in a consistent format. Currently MapQuest's support is limited to six U.S. metro areas.
