National Transportation Noise Map

(bottom) bts national transportation noise map displaying potential noise from aviation, road, and rail sources from 2016 and 2018 for the boston metropolitan area. For the 2016 and 2018 versions of the conus raster mosaic dataset, the paths referencing the underlying state datasets used to build the mosaic. Department of transportation (usdot)/ bts' national transportation atlas database (ntad).

Future versions are envisioned to include additional transportation noise sources (e.g. The data allow viewing the national picture of potential exposure to aviation and highway noise. 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.

So basically the noise has a lot more to do with road speed than road density, and airports make the biggest impact of all.

To better understand transportation sound levels, a team led by volpe center scientist meghan ahearn and geographic information systems (gis) specialist gary baker developed a simplified noise modeling tool that makes it easy to track trends in noise levels over time. Department of transportation’s bureau of transportation statistics’ (bts) initial national transportation noise map, released today, shows that more than 97 percent of the u.s. For the 2016 and 2018 versions of the conus raster mosaic dataset, the paths referencing the underlying state datasets used to build the mosaic. The 2018 national transportation noise map dataset is current as of october 2020, published by volpe and the bureau of transportation statistics (bts), and part of u.s.
