National Transportation Noise Map. Transportation noise Bay Area's loudest places to live 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 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 multimodal context this map provides can be used to better understand trends in transportation-related noise and highlight areas that may benefit from more. The layers will be updated on an annual basis, and future versions of the National. • Ground type: Acoustically soft ground was assumed for the computation of ground effects.
National Transportation Noise Map shows levels of interstate highway noise across the country. 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 • Ground type: Acoustically soft ground was assumed for the computation of ground effects.
Sounds Like a Better Plan USA Transportation Noise, Revised and Updated. 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 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)
