Data is reported on a monthly basis, by mode and type of service, for a fiscal year.\n\nThe four data items included are:\n\n1.\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Unlinked Passenger Trips \n2.\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Vehicle Revenue Miles\n3.\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Vehicle Revenue Hours\n4.\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Vehicles Operated in Maximum Service (Peak Vehicles)\n\nThis dataset presents these values in their own column in a long format (each row of the file is an individual Agency/Mode/TOS/Date). The data source is shared with the static Excel file hosted on the FTA website here: https://www.transit.dot.gov/ntd/data-product/monthly-module-adjusted-data-release. This dataset differs from the static Excel file in its formatting as well as being updated weekly, to capture data as it is reported and validated for a given publication month.\n\nMode Codes:\nAlaska Railroad (AR)\nCable Car (CC)\nCommuter Rail (CR)\nHeavy Rail (HR)\nHybrid Rail (YR)\nInclined Plane (IP)\nLight Rail (LR)\nMonorail/Automated Guideway (MG)\nStreetcar Rail (SR)\nAerial Tramway (TR)\nCommuter Bus (CB)\nBus (MB)\nBus Rapid Transit (RB)\nDemand Response (DR)\nFerryboat (FB)\nJitney (JT)\nP\u00fablico (PB)\nTrolleybus (TB)\nVanpool (VP)\n\n\nMode and Type of Service Changes and Impacts on this Time Series:\n\n\"Monthly data are reported by mode and type of service. From 2002 through 2011, there were 16 modes in the NTD. NTD monthly ridership data is now reported according to refined modal classifications. Service previously reported as bus (MB) now may be reported as either MB, Commuter Bus (CB), or Bus Rapid Transit (RB). Additionally, service previously categorized as Light Rail (LR) now may be reported as LR or Streetcar (SR). \n\nSimilarly, Types of Service were refined in Report Year 2019. From 2002 - 2018, there were two types of service: Directly Operated (DO) and Purchased Transportation (PT). As of 2019, Purchased Transportation is now classified such that agencies report the purchased transportation based on the type of contractor: general third party (PT), taxicab operator (TX), or transportation network company (TN). FTA concurrently removed the \"\"Demand Response Taxi\"\" (DT/PT) mode in 2019. FTA now considers all such service as Demand Response (DR) with Taxi (TX) type of service and this time series has been updated to reflect this change. \"\t\t\t\t\t\n\nFor more information on this dataset, please consult the full Read Me in the attached file.", "distribution": [{"@type": "dcat:Distribution", "describedBy": "https://data.transportation.gov/api/views/8bui-9xvu/columns.json", "describedByType": "application/json", "downloadURL": "https://data.transportation.gov/api/views/8bui-9xvu/rows.json?accessType=DOWNLOAD", "mediaType": "application/json"}, {"@type": "dcat:Distribution", "describedBy": "https://data.transportation.gov/api/views/8bui-9xvu/columns.rdf", "describedByType": "application/rdf+xml", "downloadURL": "https://data.transportation.gov/api/views/8bui-9xvu/rows.rdf?accessType=DOWNLOAD", "mediaType": "application/rdf+xml"}, {"@type": "dcat:Distribution", "describedBy": "https://data.transportation.gov/api/views/8bui-9xvu/columns.xml", "describedByType": "application/xml", "downloadURL": "https://data.transportation.gov/api/views/8bui-9xvu/rows.xml?accessType=DOWNLOAD", "mediaType": "application/xml"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.transportation.gov/api/views/8bui-9xvu/rows.csv?accessType=DOWNLOAD", "mediaType": "text/csv"}], "identifier": "https://data.transportation.gov/api/views/8bui-9xvu", "issued": "2025-05-06", "keyword": ["monthly ridership", "national transit database", "ntd", "public transit", "ridership", "transit", "upt", "voms", "vrh", "vrm"], "landingPage": "https://data.transportation.gov/d/8bui-9xvu", "license": "https://www.usa.gov/government-works", "modified": "2026-05-12", "programCode": ["021:000"], "publisher": {"@type": "org:Organization", "name": "Federal Transit Administration"}, "theme": ["Public Transit"], "title": "Complete Monthly Ridership (with Adjustments and Estimates)"}
