The U.S. DOT Volpe Center's Innovative Research Division serves the innovative transportation research needs of the U.S. DOT. The team supports a range of activities designed to optimize research programs’ success, from program design and administration to analysis and research.
Making our transportation system safer and stronger, more resilient and sustainable, and fairer and more equitable requires a renewed commitment to innovation. Our team oversees and coordinates key programs supporting U.S. DOT’s Office of the Secretary of Transportation (OST), its modal partners, and the transportation research community—helping design the future of transportation. The Innovative Research Division conducts analysis and research for many of its projects to assist stakeholders in understanding the opportunities and impacts of emerging technology, how certain policies and practices are integrated into research, and learning about best practices and lessons learned from technology adoption from across the country.
Some highlights of our work include:
- Administering the U.S. DOT Small Business Innovation Research (SBIR) program on behalf of OST, identifying topics and solutions that connect the power of small business innovations with emerging federal research and development needs, and awarding more than $78 million in small business funding over the last 10 years on behalf of U.S. DOT’s eight participating operating administrations
- Supporting the FHWA Exploratory Advanced Research (EAR) program with evaluation and research assessment, future topic scoping, and research transition assistance, which analyzes the underlying gaps associated with applied highway programs focused on longer-term, higher-risk research with high-payoff potential
- Supporting the Intelligent Transportation Systems Joint Program Office with developing strategy, assessing scope, and managing ITS exploratory research using a mix of traditional and innovative research approaches on topics such as artificial intelligence, cybersecurity, and Work Zone Data Exchange
- Coordinating technology transfer across the U.S. DOT including research and implementation process analysis, process design, and communication support to OST’s Technology Transfer program
- Supporting the design and implementation of the Strengthening Mobility and Revolutionizing Transportation (SMART) Grants Program, which established under the Bipartisan Infrastructure Law, aims to conduct demonstration projects focused on advanced smart community technologies and systems in order to improve transportation efficiency and safety.
- Advancing equity activities as part of the Department’s Equity Action Plan implementation, including support of information development and dissemination designed to support internal and external stakeholders in expanding access and opportunity and improving how transportation programs are delivered.
Our team of transportation research innovation experts consists of technology policy analysts, general engineers, operations research analysts, policy analysts, and contract specialists who work collaboratively to help transportation leaders invest in purpose-driven research and innovation to meet today’s challenges and modernize the transportation system of the future.
