BTS Updates Datasets to National Transportation Atlas Database

Friday, October 28, 2022

The U.S. Department of Transportation’s Bureau of Transportation Statistics today released its fall 2022 update to the National Transportation Atlas Database (NTAD), a set of nationwide geographic databases of transportation facilities, networks, and associated infrastructure.

Five new layers to the NTAD were made available with this release:

  • Railroad Bridges
  • US DOT Regional layers for the following USDOT operating administrations:
    • Federal Motor Carrier Safety Administration (FMCSA)
    • Federal Railroad Administration (FRA)
    • Federal Transit Administration (FTA)
    • Pipeline and Hazardous Materials Safety Administration (PHMSA)

The updated layers in this release include:

  • Marine Highways 
  • Intermodal Passenger Connectivity Database;
  • Bikeshare;
  • Bikeshare Scooter Systems;
  • Intermodal Freight Facilities Rail TOFC/COFC;
  • Intermodal Freight Facilities Marine Roll-on/Roll-off;
  • National Bridge Inventory Element 2022 data;
  • National Tunnel Inventory 2022 data;
  • National Tunnel Inventory Element 2022 data;
  • Navigable Waterway Network Lines;
  • Navigable Waterway Network Nodes;
  • Docks;
  • Principal Ports;
  • Waterway Locks;
  • National Dam Inventory data;
  • Congressional Districts – Updated 117th Congressional Members updated weekly;
  • 2020 Noise data;
  • Alternative Fueling Stations updated daily;
  • Aviation Facilities;
  • National Transit Map Stops;
  • National Transit Map Routes;
  • National Transit Map Agencies;
  • North American Rail Network Lines;
  • North American Rail Network Nodes;
  • Railroad Grade Crossings;
  • Nonattainment Areas;
  • National Parks;

The map below displays the locations of the intermodal freight Marine Roll-on/Roll-off (Ro-Ro) and Rail trailer-on-flatcar/container-on-flatcar (TOFC/COFC) facilities along the I-95 corridor between New York City, NY and Wilmington, Delaware. The Ro-Ro facilities show locations of ports where roll-on/roll-off vehicles and cargo can transfer from the ports to rail cars and trucks. Whereas the TOFC/COFC facilities show locations where containers can transfer from rail to ports and trucks and vice-a-versa. These facilities are essential for the efficient movement of goods through the nation’s transportation infrastructure and these layers can be used for a myriad of purposes such as geographic analysis and modeling.

About the National Transportation Atlas Database (NTAD)
NTAD data is available for download in comma separated values (CSV), Keyhole Markup Language (KML), and shapefile formats through the BTS Geospatial Data Catalog. Additionally, Open Geospatial Consortium (OGC) standard Web Feature Services (WFS) and Web Mapping Services (WMS) are available for all NTAD datasets, here and here. Also available are optimized services for fast rendering of full NTAD datasets and vector tile services for 13 of the largest NTAD datasets. These faster services are designated in NTAD by service names ending in “DS” for each layer and “VT” for the vector tiles services.

BTS now uses a dynamic NTAD publication cycle, with updated data released throughout the year as they become available from their respective government agencies. Follow BTS on Twitter, LinkedIn, and Instagram or subscribe to email updates for announcements of additional dataset releases throughout the year.
