Staff Biography

Gregg G. Fleming
B.S., Electrical Engineering
University of Lowell, MA, 1987

As Chief of the Environmental Measurement and Modeling Division at the John A. Volpe National Transportation Systems Center, Mr. Fleming has over twelve years of experience in all aspects of transportation-related acoustics. He guides the technical work of multi-faceted staff, made up of engineers, mathematicians, and computer programmers. In support of the Federal Aviation Administration (FAA), he is currently responsible for evaluating, establishing and maintaining standardized procedures for national and international aircraft noise certification. In addition, he is responsible for the technical development of the FAA's Integrated Noise Model (INM), and the FAA's Heliport Noise Model (HNM), computer programs which predict aircraft noise patterns in the vicinity of airports and heliports, respectively. In support of the Federal Highway Administration, Mr. Fleming oversees the development of the Federal Highway Administration's (FHWA) Traffic Noise Model (TNM), a computer program used to predict noise in the vicinity of highways, and used to design highway noise barriers.

Under Mr. Fleming's direction, the Acoustics Facility maintains a portable, quick-response measurement capability which is currently performing special projects in support of the FAA, the FHWA, the Federal Railroad Administration and the United States Postal Service.

Mr. Fleming is Chairman of the Transportation Research Board's Committee for Transportation Related Noise and Vibration, AIFO4. He is also a member of the Society of Automotive Engineers' (SAE) Aircraft Noise Subcommittee, A-21, as well as two SAE Project Working Teams (PWT), PWT 4.1, "Procedures for Assessment of Rotorcraft Noise in the Vicinity of Terminal Operations", and PWT 2.1, "Assessment of Methods to Compute Sound Absorption by the Atmosphere". He has served on working groups for numerous national and international standards, including standards dealing with topics such as noise measurement instrumentation, highway noise barrier evaluation, and vehicle tire/pavement noise.

Mr. Fleming also recently established and now oversees a core capability in the area of air quality measurement, modeling and analysis. He is responsible for the core technical development and validation of the FAA's Emission and Dispersion Modeling System (EDMS), a computer program used to assess air quality emissions and dispersion in the vicinity of airports.
