Abstract:

The Volpe Center Acoustics Facility, in support of the Federal Highway ; Administration (FHWA) and the California Department of Transportation ; (Caltrans), has been conducting a study to quantify and assess the accuracy ; of FHWA’s Traffic Noise Model (TNM) and make recommendations on its use. ; The TNM Validation Study involves highway noise data collection and TNM ; modeling for the purpose of data comparison. Phase 1 of the study has been ; completed. For this phase, over 100 hours of traffic noise data were ; collected at 17 highway sites around the country. The 17 sites included: ; open areas next to the highway with acoustically soft ground (e.g., lawn); ; open areas with acoustically hard ground (e.g., pavement or water); and ; areas next to the highway with an open area behind a single noise barrier. ; In comparing the measured sound levels to the TNM-predicted sound levels, ; several variables were examined, including distance from the roadway, wind ; conditions, and percentage of heavy trucks. This report discusses the ; results of Phase 1 of the TNM Validation Study.
