The Directory of Transportation Data Sources, 1993, identifies 285 transportation data sources within the U.S. Department of Transportation and other Federal agencies. The purpose of the Directory is to provide users of transportation statistics with a comprehensive inventory of transportation data sources to effect easier accessibility to information. The Directory defines a data source as a computerized data base developed within the Federal government for internal and external use, as well as regularly scheduled or special printed statistical reports published by the Federal government that are not included on a computerized system. A new edition of the Directory of Transportation Data Sources will be available in February 1995 and will include information from the U.S. private transportation industry, Canadian and Mexican statistical agencies, as well as updated federal material. The Directory is also available on diskette as an executable file.

The Freight Analysis Framework (FAF5) - Network Links dataset was created from 2017 base year data and was published on April 11, 2022 from the Bureau of Transportation Statistics (BTS) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). The FAF (Version 5) Network contains 487,384 link features. All link features are topologically connected to permit network pathbuilding and vehicle assignment using a variety of assignment algorithms. The FAF Link and the FAF Node datasets can be used together to create a network. The link features include all roads represented in prior FAF networks, and all roads in the National Highway System (NHS) and the National Highway Freight Network (NHFN) that are currently open to traffic. Other included links provide connections between intersecting routes, and to select intermodal facilities and all U.S. counties. The network consists of over 588,000 miles of equivalent road mileage. The dataset covers the 48 contiguous States plus the District of Columbia, Alaska, and Hawaii.

The Travel Monitoring Analysis System (TMAS) - Stations dataset was compiled on December 31, 2023 and was published on July 22, 2024 from the Federal Highway Administration (FHWA), and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). Geospatial station data from the FHWA TMAS database contains latitude and longitude data from over 7,000 permanent (temporal data representing each time period) traffic monitoring sites in all 50 states plus DC. Data from these stations are submitted to FHWA every month and is a result of a long standing partnership between FHWA and the state DOTs.

The Travel Monitoring Analysis System (TMAS) - Stations Table dataset was compiled on December 31, 2023 and was published on July 16, 2024 from the Federal Highway Administration (FHWA), and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). The data included in this table have been collected by the FHWA from State DOTs through 24/7 permanent count data. The attributes are used by FHWA for its Travel Monitoring Analysis System and external agencies and have been intentionally limited to _location referencing attributes since the core station description attribute data are contained within TMAS. The attributes in the Station data correspond with the Station file format found in Chapter 6 of the 2001 Traffic Monitoring Guide (https://doi.org/10.21949/1519109). A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/1529084

FAF domestic region level datasets and products provide information for states, state portions of large metropolitan areas, and remainders of states. Metropolitan areas consist of Metropolitan Statistical Areas or Consolidated Statistical Areas as defined by the Office of Management and Budget. When a metropolitan area is entirely within a state or when a state's portion of a multi-state metropolitan area is large enough to support the sampling procedures in the Commodity Flow Survey, the area becomes a separate FAF region. Small single-state metropolitan areas and small portions of a multi-state metropolitan area are part of the State or Remainder of State. FAF has two metropolitan areas that are each divided into three FAF regions, four that are each divided into two FAF regions, and several that have small pieces combined with States or Remainders of States.

The Fatality Analysis Reporting System (FARS) 2023 Initial Release - Vehicle Information Auxiliary File dataset was compiled from January 1, 2023 to December 31, 2023 by the National Highway Traffic Safety Administration (NHTSA) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). This file contain elements derived from the FARS datasets to make it easier to extract certain data classifications and topical areas. This file downloaded from the open data catalog is synonymous with what USDOT/NHTSA releases for FARS as the VEH_AUX file. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/1529024

The Fataility Analysis Reporting System (FARS) dataset is as of July 1, 2017, and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics's (BTS's) National Transportation Atlas Database (NTAD). One of the primary objectives of the National Highway Traffic Safety Administration (NHTSA) is to reduce the staggering human toll and property damage that motor vehicle traffic crashes impose on our society. FARS is a census of fatal motor vehicle crashes with a set of data files documenting all qualifying fatalities that occurred within the 50 States, the District of Columbia, and Puerto Rico since 1975. To qualify as a FARS case, the crash had to involve a motor vehicle traveling on a trafficway customarily open to the public, and must have resulted in the death of a motorist or a non-motorist within 30 days of the crash. This data file contains information about crash characteristics and environmental conditions at the time of the crash. There is one record per crash. Please note: 207 records in this database were geocoded to latitude and logtitude of 0,0 due to lack of location information or errors in the reported locations. FARS data are made available to the public in Statistical Analysis System (SAS) data files as well as Database Files (DBF). Over the years changes have been made to the type of data collected and the way the data are presented in the SAS data files. Some data elements have been dropped and new ones added, coding of individual data elements has changed, and new SAS data files have been created. Coding changes and the years for which individual data items are available are shown in the “Data Element Definitions and Codes” section of this document. The FARS Coding and Editing Manual contains a detailed description of each SAS data elements including coding instructions and attribute definitions. The Coding Manual is published for each year of data collection. Years 2001 to current are available at: http://www-nrd.nhtsa.dot.gov/Cats/listpublications.aspx?Id=J&ShowBy=DocType Note: In this manual the word vehicle means in-transport motor vehicle unless otherwise noted.

Data from all U.S. air carrier domestic and international, scheduled passenger flights. International data in system total includes U.S. carrier operations to and from the U.S. and from one foreign point to another foreign point. BTS’ Airlines and Airports available here (https://www.transtats.bts.gov/Data_Elements.aspx) does not include U.S. carriers’ foreign point-to-point flights.

This data is collected by the U.S. Department of Transportation, Bureau of Transportation Statistics (BTS), U.S. Air Carrier Traffic Statistics reported in BTS' monthly Air Traffic Data release, available here (https://www.bts.dot.gov/statistical-releases).

The Travel Monitoring Analysis System (TMAS) - Volume dataset was compiled on December 31, 2023 and was published on July 16, 2024 from the Federal Highway Administration (FHWA), and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). The TMAS data included in this table have been collected by the FHWA from State DOTs through (temporal data representing each time period) permanent count data. DOTs determine what volume data is reported for any given month or day within the month. Each record in the volume data for the reported site, direction or lane is for the given day of record (it contains all 24 hours of data). The attributes are used by FHWA for its Travel Monitoring Analysis System and external agencies and have been intentionally limited to _location referencing attributes since the core station description attribute data are contained within TMAS. The attributes in the Volume data correspond with the Volume file format found in Chapter 6 of the 2001 Traffic Monitoring Guide (https://doi.org/10.21949/1519109).

The Air Carrier Statistics database, also known as the T-100 data bank, contains domestic and international airline market and segment data. certificated U.S. air carriers report monthly air carrier traffic information using Form T-100. Foreign carriers having at least one point of service in the United States or one of its territories report monthly air carrier traffic information using Form T-100(f). The data is collected by the Office of Airline Information, Bureau of Transportation Statistics, Research and Innovative Technology Administration.

The National Bridge Inventory dataset is as of June 27, 2024 from the Federal Highway Administration (FHWA) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). The data describes more than 615,000 of the Nation's bridges located on public roads, including Interstate Highways, U.S. highways, State and county roads, as well as publicly-accessible bridges on Federal and Tribal lands. The inventory data present a complete picture of the location, description, classification, and general condition data for each bridge. The element data present a breakdown of the condition of each structural and bridge management element for each bridge on the National Highway System (NHS). The Recording and Coding Guide for the Structure Inventory and Appraisal of the Nation's Bridges contains a detailed description of each data element including coding instructions and attribute definitions. The Coding Guide is available at: https://doi.org/10.21949/1519105.

The Transportation Safety CD-ROM is another product in the BTS State and Metropolitan Analysis for Regional Transportation (SMART) series. The SMART project was conceived to assist metropolitan planning organizations (MPO)and state department of transportation (DOT) planners in responding to the increased requirements of the Intermodal Surface Transportation Efficiency Act (ISTEA) of 1991 and the Clean Air Act Amendment of 1990. The project is an experiment in communications that involves gathering the collective wisdom of the transportation planning community and making the materials generated by MPOs and DOTs easy to use and share.

The Transportation Safety CD-ROM contains over 200 safety-related reports, accident studies, award winning community programs, program planners, data sets and youth programs collected from MPOs, state DOTs, the federal government, and professional associations during the last quarter of 1995. Safety topics include rail, roadway, motor vehicles, transit, bicycle and pedestrian safety, and occupant protection.

The CD-ROM, Transportation Safety, has been released byt the Bureau of Transportation Statistics (BTS, "http://www.bts.gov" of the U.S. Department of Transportation (DOT).
