National Transportation Noise Map

Tuesday, March 2, 2021

The purpose of the National Transportation Noise Map is to facilitate USDOT stakeholders, researchers, industry and the public in their efforts to track trends in transportation-related noise, by mode, and collectively for multiple transportation modes. The National Transportation Noise Map provides a basis for understanding what-if scenarios and helping policy makers and planners to prioritize noise-related transportation investments. The data allow viewing the national picture of potential exposure to aviation and highway noise. The data also allow viewing of the potential exposure at the state or county level. This is the first time BTS is venturing out into this world of providing a noise map and data that people can use. Being able to see the modes together is exciting. The public typically only sees these data individually, and now they will see how these interdependent data sets will present a more comprehensive picture

The National Transportation Noise Map will be an addition to the National Transportation Atlas Database, a set of nationwide geographic databases of transportation facilities, networks, and associated infrastructure available from the BTS Geospatial Data Catalog.  The layers will be updated on an annual basis, and future versions of the National Transportation Noise Map are envisioned to include additional transportation noise sources, such as rail and maritime.
