The U.S. DOT Volpe Center’s Economic Analysis Division serves transportation leaders who make policy, programmatic, regulatory, and procurement decisions by providing a comprehensive range of economic analysis, equity impact analysis, industry analysis, and forecasting services—across all modes of transportation.
Our team provides regulatory and financial decision support, evaluation and impact assessment, and travel behavior modeling and forecasting through benefit-cost analysis, econometric modeling, survey research, and interviews and focus groups.
Because our economic, survey research, and evaluation skills have many synergies with engineering, environmental science, information technology, and human factors, our team engages in frequent cross-Center collaboration to provide thorough, multidisciplinary, multimodal analyses and solutions.
We empower transportation leaders, giving them the data, analysis, and forecasting needed to make smart decisions across programs, modes, and Departmental priorities.
We partner with sponsors to provide them the information they need to structure, manage, and evaluate their programs to deliver goals efficiently and equitably.
