pdubey@v1-media.com on February 2, 2022 - in Transportation

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

The updated layers in this release include:

  • National Transit Map data;
    • Transit Stops;
    • Transit Routes;
    • Transit Agencies;
  • North American Rail Lines;
  • North American Rail Nodes;
  • National Bridge Inventory and Element 2021 data;
  • Intermodal Passenger Connectivity Database attribute correction;
  • Bikeshare attribute correction;
  • Bikeshare Scooter Systems attribute correction;
  • Alternative Fueling Stations;
  • National Parks;

 

The hexagon bin map below shows the concentration of bridges in poor condition across the U.S. based on the new 2021 National Bridge Inventory (NBI) data from the Federal Highway Administration. In the NBI 2021 data, 7% of bridges were rated in poor condition. These and similar data can be of use to State and local governments and others implementing the Investments in Infrastructure and Jobs Act of 2021 (IIJA).

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. Additionally, Open Geospatial Consortium (OGC) standard Web Feature Services (WFS), including Web Mapping Services (WMS), are available for all NTAD datasets. 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 TwitterLinkedIn, and Instagram or subscribe to email updates for announcements of additional dataset releases throughout the year.
