The Intermodal Freight Facilities - Pipeline Terminals dataset was compiled on February 02, 2021 and was updated on April 21, 2021 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). Pipeline terminals interface between pipeline mode and other transportation modes. They have the ability to receive or deliver freight commodities via pipeline and truck/rail/water. The data consists of location information, truck/rail/water mode connections, storage capacity, and a list of commodities handled at the terminal. Geographical coverage includes the United States and U.S. territories. This dataset is one of several layers in the Bureau of Transportation Statistics (BTS) Intermodal Freight Facility Database.

The Intermodal Freight Facilities - Rail TOFC/COFC dataset was compiled on December 10, 2018 and was updated on July 22, 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). When available, the primary sources for this dataset were the websites of the railroads. Every facility is assumed to be served by both rail and truck, and those facilities which support port operations, the name of the port is also identified. The dataset also includes the services provided at each facility (TOFC only, COFC only, or both TOFC and COFC), and the Station Point Location Code (SPLC) associated with the rail facility. This dataset is one of several layers in the Bureau of Transportation Statistics (BTS) Intermodal Freight Facility Database.

The Intermodal Freight Facilities - Marine Roll-on/Roll-off dataset was compiled on July 01, 2019 and was updated on July 22, 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). When available, primary sources for this dataset were the websites of the ports, as well as port operators. Every facility is associated with a port and assumed to be served by both marine and truck, and those facilities which support rail operations, the reporting code for the operating rail company is also identified. The dataset also includes at least one Navigation Unit ID (NAV_UNIT_ID) from the U.S. Army Corps of Engineers (USACE) Port Facilities dataset which is associated with the Ro/Ro terminal. This dataset is one of several layers in the Bureau of Transportation Statistics (BTS) Intermodal Freight Facility Database.

The National Transit Map - Agencies dataset was compiled on September 09, 2024 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 National Transit Map (NTM) is a nationwide catalog of fixed-guideway and fixed-route transit service in America. It is compiled using General Transit Feed Specification (GTFS) Schedule data. The GTFS Schedule documentation is available at, https://gtfs.org/schedule/. The NTM Agencies dataset represents the physical addresses of participating transit agencies. Regarding data coverage and licenses, starting in Report Year 2023, the Federal Transit Administration (FTA) has required National Transit Database (NTD) Reporters to submit General Transit Feed Specification (GTFS) data. Reporters will submit GTFS during their reporting period, which is determined by their fiscal year end date. All GTFS data submitted to the NTD will enter the public domain. Prior to the GTFS requirement, transit agencies voluntarily participated in the NTM and granted the U.S. Department of Transportation (USDOT) a Creative Commons Attribution 3.0 United States (CC-BY-3.0) license. The CC-BY-3.0 license is available at, https://creativecommons.org/licenses/by/3.0/us/legalcode.

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 BETA release of the Intermodal Freight Facilities - Liquid Bulk dataset was compiled on November 28, 2023 and was completed on January 19, 2024 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). This dataset maps polygons with attributes for port facilities that handle the liquid bulk commodity. This includes liquid materials that are transferred in bulk as opposed to containerized transport. Liquid bulk is most commonly transferred by three (3) modes of transportation: Truck, Rail or Barge. An intermodal facility is defined as a location where two (2) or more modes of transportation are serviced. Locations included in this dataset represent facilities where bulk liquids do not change state (e.g., refinement, liquefaction, manufacturing, fueling, etc.). Data was sourced from the public domain from March 2023 to November 2023. Prioritization of data collection was put towards collecting data for facility locations serviced by ship or barge. Excluded are Intermodal facilities which include pipelines as that is covered in the NTAD Intermodal Freight Facilities Pipeline Terminals. Note that terminal locations are prone to change ownership. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/1529991

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).
