VEHICLE EMISSION NOISE EVALUATION FOR ARIZONA SPECIFIC STAMINA 2.0 AND TRAFFIC NOISE MODEL (TNM)

The University of Louisville Research Foundation conducted a series of Reference Energy Mean Emission Level (REMEL) measurements of individual vehicle operations in the state of Arizona. 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. The following conclusions are drawn from the results of this study: The Arizona TNM REMEL data are different than the FHWA/TSC national TNM REMEL at a 95% confidence level for all three vehicle types addressed in this report; Arizona state-specific REMEL data increase the accuracy of both STAMINA and TNM over the same models using the FHWA/TSC national REMEL data, when modeling sites in the state of Arizona; The most accurate prediction method for sites in Arizona at distances of up to 400 ft from the roadway is the STAMINA model using Arizona state-specific REMEL data; The least accurate prediction method for Arizona sites at distances up to 400 ft from the roadway is the TNM model using national REMEL data; and TNM significantly over-predicts sound levels whether using either FHWA/TSC or Arizona state-specific REMEL data.
