This report presents the results of the statistical analysis of FHWA traffic noise data collected in Colorado, Florida, North Carolina and Washington. Prediction equations of the peak dBA levels of trucks as functions of speed are derived for each of the axle groups: 2, 3, 4, 5, 6, 3-5, and each of the four states. These equations are used to establish vehicle reference emission levels for medium and heavy trucks. Similar results are derived for noise levels in octave bands at frequencies 31.6, 63, 125, 250, 500, 1K, 2K, 4K and 8K Hz. Attenuation rates are estimated for each of the four states. These results can be used in highway noise prediction models.

In March 1998, the Federal Highway Administration (FHWA) Office of Natural Environment, released the FHWA Traffic Noise Model (FHWA TNM) Version 1.0, a state-of-the-art computer program for highway traffic noise prediction and analysis. Since then, the FHWA, with assistance from the Volpe Center Acoustics Facility (Volpe Center) and Foliage Software Systems (FSS), have released updates of TNM (Versions 1.0a, and 1.0b) in March 1999 and August 1999, respectively. In support of the FHWA and the California Department of Transportation, the Volpe Center and FSS released Version 1.1 in September 2000. TNM 2.0 is the latest release of the TNM software. Two companion reports were released with TNM Version 1.0, a Technical Manual that describes the acoustics within TNM and a User's Guide. In addition, prior to TNM release, a data report was published that describes the vehicle noise-emissions data base within TNM. This document is an addendum to the FHWA TNM Version 1.0 User's Guide. It details the enhancements in the program up to and including Version 2.0.
