National Transportation Noise Map. This 'Noise Map' Reveals the Loudest Areas in the Country Mental Floss 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 In 2017, BTS launched the National Transportation Noise Map to track trends in transportation-related noise, both individually by mode and collectively over time at the national level

The data also allow viewing of the potential exposure at. This map was created by overlaying the Bureau of Transportation Statistics' Year 2020 National Transportation Noise Map with 5-year (2016-2020) population data at the block group level from the Census Bureau's American Community Survey The data also allow viewing of the potential exposure at.
Enhancing the BTS National Transportation Noise Map Volpe National Transportation Systems Center. The National Transportation Noise Exposure Map was created by overlaying the Bureau of Transportation Statistics' Year 2020 National Transportation Noise Map with 5-year (2016-2020) population data at the block group level from the Census Bureau's American Community Survey The following assumptions apply to the road noise modeling in the National Transportation Noise Map: • Weather: TNM's default temperature and humidity levels are used (68 degrees F, 50% relative humidity)
(PDF) The National Transportation Noise Exposure Map. 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 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
