This page provides guidance and suggestions on analyze and evaluate feasibility and reasonableness factors when considering noise barriers as an abatement measure.
- Analysis: The “Noise Barrier Acceptance Criteria: Analysis” report examines the feasibility and reasonableness factors in the 23 Code of Federal Regulations (CFR) Part 772 as implemented in the individual state highway agency noise policies individually and in combination with each other to identify optimized combinations of values - PDF (7MB)
- Evaluation Tools: The “Noise Barrier Acceptance Criteria: Evaluation Tools” There are three files associated with this topic. Two tools (Noise Abatement Feasibility and Reasonableness Analysis Tool (NAFRAT) Version 1 & Noise Abatement Reasonableness Sensitivity Analysis Tool (NARSAT) Version 1) developed to evaluate the effects of policy changes on the feasibility and reasonableness of noise abatement for the factors described in the Federal Highway Administration (FHWA) noise regulation in Title 23 CFR Part 772 as implemented in the individual state highway agency (SHA) noise policies. These tools allow a user to evaluate different combinations of factors to determine the effects of policy changes. There is also a supplemental report discussing both tools collectively - PDF (872KB)
Note: The spreadsheets are tools for States to consider different ways to consider their feasibility and reasonableness criteria. You must download these files for use in MS Excel.
