The Volpe Center Acoustics Facility, in support of the Federal Highway Administration (FHWA), investigated the implementation of pavement effects in the 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.


The authors wish to thank the Federal Highway Administration (FHWA) for their vision and support of this study.  The authors also wish to thank several U.S. State highway agencies and other organizations for cooperation in data collection logistics, sharing data, and discussions involving various aspects of this study; this includes: California Department of Transportation, Arizona Department of Transportation, Ohio Department of Transportation, Massachusetts Department of Transportation, The Transtec Group, and Illingworth & Rodkin.  In addition to the authors conducting field measurements, other folks were also involved; the authors wish to thank Mark Ferroni, Adam Alexander, Trevor May, and Gina Barberio.
