Book Description
This study was conducted to determine if the noise emission characteristics of Arizona highway vehicles are consistent with the data contained in the Federal Highway Administration's (FHWA's) Traffic Noise Model (TNM). This study also examined the prediction accuracy of the TNM and STAMINA models. Field measurements were made at ten separate locations representative of typical Arizona topography and traffic conditions. These sites were modeled and both TNM and STAMINA were used to generate predicted sound levels at each measurement location.

Book Description
This guide which was produced in an effort to consolidate and disseminate research information relating to traffic noise and develop guidelines for the abatement of traffic generated noise through highway design procedures and techniques, reviews the nature of noise and presents a systems approach to the attack of noise problems and its interrelated aspects. Some insight is provided into the problems faced by highway planners and designers and remedial measures are presented for noise reduction. Procedures are outlined which aid in conducting noise studies. Design features are described which aid in obtaining attenuation when studies indicate such measures are desirable and feasible. Several procedures for noise measurement are included in an appendix.

Book Description
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.

Book Description
The Volpe Center Acoustics Facility, in support of the Federal HighwayAdministration (FHWA) and the California Department of Transportation(Caltrans), has been conducting a study to quantify and assess the accuracyof FHWA's Traffic Noise Model (TNM) and make recommendations on its use. The TNM Validation Study involves highway noise data collection and TNMmodeling for the purpose of data comparison. Phase 1 of the study has beencompleted. For this phase, over 100 hours of traffic noise data werecollected at 17 highway sites around the country.

Book Description
The Volpe Center Acoustics Facility, in support of theFederal Highway Administration(FHWA), investigatedthe implementation of pavement effects inthe FHWA Traffic Noise Model (TNM). Three options were considered, resulting in the recommendation of two options: 1) implementation of user-defined pavement-specific emission levels (REMELs), with proof of adequate data; and 2) implementation of on-board sound intensity (OBSI)-adjusted tire/pavement noise source levels, implemented as a large database in the FHWA TNM and also as a user-defined option. Each option would also include adjusting for the pavement sound absorption by applying pavement-specific effective flow resistivity (EFR) values.
