Assessing Driving Performance Using Refined Ground-Truth Trip Recorders
Data-processing pipeline for on-road ground-truth trip recorder tests and CARLA simulation (project report to NHTSA).Sponsor: National Highway Traffic Safety Administration (NHTSA) · Period: through 2024
The project used instrumented vehicles as “ground-truth” trip recorders to assess driving performance, especially around intersections, and refined how accurately such recorders capture the surrounding traffic.
My contributions
- Worked on radar tracking and sensor fusion, combining radar, camera, and LiDAR outputs to improve accuracy in intersection-based safety assessments.
- Co-author of the project’s final report to NHTSA (LeBlanc et al., 2024; in review).

Efe Yarbasi is an Assistant Research Scientist in the Engineering Systems Group at the University of Michigan Transportation Research Institute (UMTRI). His research covers the safety of automated and driver-assistance systems and the electrification of transportation. He serves as principal investigator and co-principal investigator on projects sponsored by NHTSA, Toyota Motor North America, and the National Cooperative Highway Research Program. He co-leads the Low Altitude Airspace Working Group at M-Air.
He holds a PhD in Aerospace Engineering from Georgia Tech. There he worked in the Aerospace Systems Design Laboratory under Prof. Dimitri Mavris and developed methods to find and reduce the uncertainties that matter most in complex, multi-disciplinary designs. He is a member of AIAA and IEEE.
Students: I enjoy working with students. If you are interested in my research, please send me an email.
