Research to Support Noise Rulemaking
Project Information
Conduct research to inform the development of a notice of proposed rulemaking (NPRM) for 23 CFR 772, Procedures for Abatement of Highway Traffic Noise and Construction Noise. Conduct sensitivity analyses with the Federal Highway Administration (FHWA) Traffic Noise Model to define parameters for complex roads, screening tools, and project exemptions to be included in the proposed rule. Conduct regulatory research to understand historical changes and inform recommendations for proposed changes to the rule. State departments of transportation (DOTs) are required to investigate traffic noise impacts adjacent to federally funded highway construction projects and consider feasible and reasonable abatement measures. Based on feedback from stakeholders and the public, FHWA is working to revise 23 CFR 772 to improve clarity.
