Oregon Department of Transportation Traffic Noise Prediction Manual
This document serves as the official guide for the Oregon Department of Transportation (ODOT) regarding highway traffic noise and construction noise. It details the implementation of the Federal Highway Administration (FHWA) Noise Standard, defining how ODOT identifies noise impacts and evaluates abatement measures for federal-aid highway projects. The manual covers the background of noise regulations, including the National Environmental Policy Act and the Federal-Aid Highway Act of 1970, and establishes ODOT's specific procedures for compliance.
Covers: Introduction · Noise Standards · Definitions · Applicability · Traffic Noise Prediction · Analysis of Traffic Noise Impacts
