Traffic noise compliance is governed by sections of the National Environmental Policy Act (NEPA) that address the avoidance and mitigation of traffic noise impacts resulting from roadway projects and the Federal Aid Highway Act. This act mandates FHWA to develop and promulgate guidelines and standards for highway noise levels. Environmental practitioners can use these tools to prepare materials compliant with those regulations.

Templates and Spreadsheets
Title Date Description Format
Standard Language for Documenting Traffic Noise Analysis
12/19 Standard text to be used when preparing NEPA documents specific to traffic noise.
Template: No Noise Impact
03/20 Used for the noise technical report when the noise analysis indicated no predicted noise impacts.
Template: Noise Impacts No Abatement
03/20 Used for the noise technical report when the noise analysis indicated predicted noise impacts, but no noise abatement is proposed.
Template: Noise Impacts with Abatement
03/20 Used for the noise technical report when the noise analysis indicated predicted noise impacts and noise abatement is proposed.
Alternate Barrier Cost Assessment Worksheet 06/19 Used for the Alternate Barrier Cost assessment to determine if projected costs directly associated with the construction of a proposed barrier would be unreasonably high, and therefore not cost reasonable.
Template: Letter Related to Noise Contours for Land Use Planning

FHWA Regulations and Guidance
Title Date Description Format
Code of Federal Regulations, Title 23, Part 772: Procedures for Abatement of Highway Traffic Noise and Construction Noise   Provides FHWA procedures for noise studies and noise abatement measures pursuant to the standards mandated by 23 USC 109, and all highway projects developed in conformance with this 23 CFR 772 have met the FHWA noise standards
FHWA Highway Traffic Noise Website   Provides guidance to control the undesirable effects of highway traffic noise using a three-part approach: noise compatible planning, source control and highway project noise mitigation
Highway Traffic Noise: Analysis and Abatement Guidance   Provides guidance from FHWA for the applying the strictly voluntary 23 CFR 772 in the analysis and abatement of highway traffic noise based on lessons learned and best practices; it does not constitute the establishment of an FHWA standard
FHWA Highway Traffic Noise: Traffic Noise Model Web Page   Provides guidance about the background of the FHWA Traffic Noise Model (FHWA TNM) and links with additional information
FHWA Highway Traffic Noise: Measurement of Highway-Related Noise Web Page   Provides guidance for measuring different aspects of highway noise to determine or predict community impacts during urban planning; for using a precise, uniform, field measurement practice that allows a valid comparison of results from similar studies performed by a variety of transportation practitioners and researchers; and for determining existing noise in the vicinity of a highway or determining vehicle noise emissions
