Noise Data 2020
The 2020 National Transportation Noise Map dataset utilized transportation mode data from 2020 to model transportation noise at the national level and was released in November 2022. It was published by the Bureau of Transportation Statistics (BTS) as part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). Please see the website https://www.bts.gov/geospatial/national-transportation-noise-map for downloads and more information about these datasets. For web services of these data, please navigate to https://tiles.arcgis.com/tiles/xOi1kZaI0eWDREZv/arcgis/rest/services and search for service names beginning with "NTAD_Noise_2020." Please contact ntad@dot.gov with any questions.
Data within the National Transportation Noise Map represent potential noise levels across the nation for an average annual day for the specified year. These data are intended to facilitate the tracking of trends in transportation-related noise by mode, and collectively over time and should not be used to evaluate noise levels in individual locations and/or at specific times. This dataset is developed using a 24-hr equivalent A-weighted sound level (denoted by LAeq) noise metric. The results represent the approximate average noise energy due to transportation noise sources over a 24-hour period at the receptor locations where noise is computed. Layers include Aviation, Rail (Freight and Passenger), and Road Noise for the Lower 48 States as well as Alaska and Hawaii.
