The U.S. DOT Volpe Center's Environmental Measurement and Modeling Division measures and models acoustics and air quality to support transportation-related noise, air quality, and safety initiatives. Our work is used to develop energy and environmental policies and drive reductions in carbon and other greenhouse gas emissions.
Our team measures noise and emissions for all modes of transportation and conducts long-term noise monitoring in remote locations, such as national parks.
We model noise, emissions, and dispersion from transportation-related sources to understand environmental and technological impacts and improve quality of life.
