Abstract:By most forecasts, the U.S. population is projected to grow by over 100 million by 2050. As demand for transportation increases, transportation-related noise will also change. The Bureau of Transportation Statistics (BTS) has started a national, multi-modal transportation noise mapping initiative to facilitate the tracking of trends in transportation-related noise as changes occur over time. This document describes the methodology and assumptions included in the National Transportation Noise Map (NTNM) which consists of noise inventory layers for aviation, roadway, and passenger rail transportation sources. Future versions are envisioned to include additional transportation noise sources (e.g. railroad freight, maritime). Visit the National Transportation Noise Map at https://maps.dot.gov/BTS/NationalTransportationNoiseMap/ and https://data.bts.gov/stories/s/National-Transportation-Noise-Map/ri89-bhxh/
