Headshot of Gregg Fleming

As the director of the U.S. DOT Volpe Center's Center for Policy, Planning, and Environment, Gregg G. Fleming has more than 30 years of experience in all aspects of transportation-related issues. He has guided the work of numerous multifaceted teams on projects supporting government, industry, and academia, including the Office of the Secretary of Transportation, the United Nations' International Civil Aviation Organization (ICAO), the Federal Aviation Administration (FAA), the Federal Highway Administration (FHWA), the National Park Service, the National Aeronautics and Space Administration, the Environmental Protection Agency, and National Academy of Sciences.

In his role as center director for Policy, Planning, and Environment, Fleming oversees seven technical areas—Economic Analysis, Policy Analysis and Strategic Planning, Transportation Planning, Environmental Measurement and Modeling, Energy Analysis and Sustainability, Environmental Science and Engineering, and Program Development and Capacity Building—as well as the CAFE Program Office. The Center for Policy, Planning, and Environment provides a full range of planning, evaluation, compliance, and implementation assistance to transportation decision makers at the local, regional, state, and federal levels.

He is responsible for the design, development, and deployment of internationally recognized analysis tools, including FAA's Aviation Environmental Design Tool (AEDT) and FHWA's Traffic Noise Model (TNM). The FAA tool is used for establishing national and international policies pertaining to aviation and the environment, including noise and environmental stringencies and domestic analyses in support of the Next Generation Air Transportation System (NextGen). FHWA's TNM is used for designing highway noise barriers and informing the federal distribution of noise mitigation funds related to highway noise barrier construction.

Fleming is also responsible for evaluating, establishing, and maintaining standardized procedures for national and international aircraft noise certification. Most recently, he has been working with industry and academia on projects related to alternative fuels, with particular focus on approaches to achieving carbon-neutral growth.

Under Fleming's direction, the Center for Policy, Planning, and Environment maintains an extensive laboratory of measurement and monitoring instrumentation, including a quick-response capability to support all aspects of transportation-related environmental measurements.

He currently co-chairs the ICAO Modeling and Databases Group and represents FAA at the United Nations Framework Convention on Climate Change. Fleming is chairman emeritus of the Transportation Research Board's Committee for Transportation Related Noise and Vibration and is active in the Society of Automotive Engineers, as well as numerous other technical organizations.

He holds a BS in electrical engineering from the University of Massachusetts Lowell (Lowell, MA). Fleming has co-authored numerous peer-reviewed journal articles and participated substantially in the development of national and international standards and policy documents pertaining to transportation-related issues.
