The U.S. Department of Transportation’s (DOT) Bureau of Transportation Statistics (BTS) is asking transit agencies to submit data by Nov. 15 for the second edition of the National Transit Map. Agencies must register their General Transit Feed Specification (GTFS) data in a voluntary process by that date for BTS to harvest it for the second edition, which will be released in late 2016. The National Transit Map is a geospatial database containing information from transit agencies that provides open, machine-readable data about transit stops, routes, and schedules. The first version of the National Transit Map, released in September 2016, contained data from more than 200 transit agencies including 84 percent of the top 25 urban transit agencies with fixed-route service, 74 percent of the top 50 agencies, and about one third of all urban transit agencies with fixed-route service. The ranking of transit agencies included urban transit agencies with fixed route services and were based on maximum revenue vehicles operated or Vehicles Operated in Annual Maximum Service (VOMS).
