Description: The Truck Stop Parking dataset was compiled on April 09, 2019 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 truck parking data was collected as part of the Jason's Law Truck Parking Survey requirement of MAP-21 (PL 112-141) to provide a "national priority on addressing the shortage of long-term parking for commercial motor vehicles on the National Highway System to improve the safety of motorized and non-motorized users and for commercial motor vehicle operators." Jason's Law required the USDOT to conduct a survey and comparative assessment in consultation with relevant State motor carrier representatives to: 1. Evaluate the capability of the State to provide adequate parking and rest facilities for commercial motor vehicles engaged in interstate transportation; 2. Assess the volume of commercial motor vehicle traffic in the State; and 3. Develop a system of metrics to measure the adequacy of commercial motor vehicle parking facilities in the State.

Description: The Railroad Grade Crossings dataset was updated on July 13, 2025 and was created on July 15, 2025 by the Federal Railroad Administration (FRA), and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). The Railroad Grade Crossings is a spatial file that originates from the National Highway-Rail Crossing Inventory Program. The program is to provide information to the public, Federal, State, and Local governments, as well as the railroad industry for information and the improvements of safety at highway-rail crossings. Some railroad grade crossings were located outside the US or their respective states, and relocated to latitude longitude 0,0.

Description: 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.
