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 - Air-to-Truck dataset was compiled on January 15, 2019 and was updated on February 24, 2020 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 includes air to truck intermodal freight facilities for the top 60 airports by total freight moved in 2017. 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 Travel Monitoring Analysis System (TMAS) - Class dataset was updated on December 31, 2023 and was created on July 16, 2024 by 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 Continuous Vehicle Classification (CVC) data represents both the FHWA 13 vehicle types and length-based class as defined by the 2001 Traffic Monitoring Guide (TMG).

The National Highway Traffic Safety Administration (NHTSA) Regions dataset is as of July 14, 2023 from 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 dataset depicts NHTSA's Regional Operations and Program Delivery Office regional boundaries. It identifies which states and territories are associated with each region. NHTSA's regions help States use data to identify their highway safety challenges, evaluate safety programs and activities, and provide technical assistance to State program managers to support the implementation of impactful behavioral highway safety programs.

The Marine Highways dataset was created on June 15, 2016 and was updated on September 16, 2024 by the U.S. Maritime Administration (MARAD) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). MARAD's Marine Highway Program is a Maritime Administration led program to expand the use of our Nation's navigable waterways to relieve landside congestion, reduce air emissions, and generate other public benefits by increasing the efficiency of the surface transportation system (https://www.maritime.dot.gov/grants/marine-highways/marine-highway). This dataset contains the locations of all 31 maritime routes that have been designated as Marine Highways by the Secretary of U.S. DOT and contain 2022 tonnage values from the US Army Corps of Engineers (USACE). Routes included in this dataset are diagrammatic and may not depict all waterways and port connectors that are considered to be part of the U.S. Marine Highway System.

A highway-rail crossing is a location where a public highway, road, street, or private roadway, including associated sidewalks and pathways, crosses one or more railroad tracks. All such crossings are reported by railroads and state Department of Transportations to the FRA on Form FRA F 6180.71 U.S. DOT Crossing Inventory Form. Each location has an assigned U.S. DOT Grade Crossing Identification Number, or crossing ID. This dataset is the source dataset and contains raw data values. It replaced the legacy data download (https://safetydata.fra.dot.gov/OfficeofSafety/publicsite/DownloadCrossingInventoryData.aspx). To download data that contains data in a user-friendly human-readable format, please reference https://data.transportation.gov/Railroads/Crossing-Inventory-Data-Form-71-Historical/vhwz-raag/about_data.
