16. Abstract Federal-aid highway projects that require a traffic noise analysis must use the latest version of the Federal Highway Administration Traffic Noise Model (FHWA TNM), according to 23 CFR 772.9(a). While the FHWA TNM provides for the accurate prediction of traffic noise levels along the wayside of a highway, accurate results are not necessarily guaranteed. Accurate results depend upon the quality of the input data and the care with which the user replicates objects in the physical world with objects in the virtual world of the FHWA TNM. This study provides TNM users with the best sources for information and input data that are critical to the development of an accurate model of highway traffic noise. This report provides best practices and guidance related to:
