Who We Are
HASS COE brings together knowledge across USDOT, academia, and industry on highly automated transportation systems, exploring new technologies and their potential impact on safety. Based in the USDOT Office of Research and Technology, our office and its expert staff complement and augment each USDOT Operating Administration’s own resources, especially where automation systems intersect across multiple modes of transportation. By engaging academia and industry as partners in safety, we inform a safe national framework for highly automated systems, today and tomorrow.
Advance the safe and responsible integration of automation across the transportation ecosystem.
Ensure federal capacity to review, assess, and validate the safety of automated technologies comprehensively across modes while enabling cross-sector collaboration for a holistic approach to the safe integration of automation in transportation.
In Congressional order H.R. 1865, Further Consolidated Appropriations Act, 2020 (2019), Congress mandated that HASS COE provide support and partnership to USDOT Operating Administrations in reviewing, assessing, and validating the safety of highly automated systems. Congress directed HASS COE to offer a USDOT-wide expert resource on the safety implications of highly automated systems, integrating expertise in artificial intelligence, computer science, data analytics, machine learning, sensors, and other technologies.
The HASS COE team is made up of leaders from government, academia, and industry who bring extensive, new kinds of expertise to USDOT resources. Our senior-level specialists bring insight and perspective, operating in a highly collaborative, interdisciplinary model across subjects and skillsets.
- 17 specialists (as of July 2023)
- 25+ years of experience
- 78% bring expertise from outside USDOT
- 89% has master's level education or higher
