CCEE associate professor Dr. Ali Hajbabaie was recently interviewed on CBS 17 about his research on adding a fourth light on traffic signals to help traffic flow with autonomous vehicles.
“We want to make the traffic going through the intersection more efficient, at the same time safer and we want to save on fuel cost options.”
Ali Hajbabaie
Hajbabaie and other researchers are looking at the effects of adding a light to intersections that would signal to drivers to follow autonomous vehicles that would act as guides to get through the intersection safely. They are continuing the study by examining how pedestrians play a part in the light system.
Hajbabaie is interested in real-time optimization of large-scale complex engineering systems represented by models with a high degree of realism. His research is focused on traffic operations and control in the presence of connected human-driven and self-driving cars. Hajbabaie and his research group use multi-scale analysis, modeling, and optimization to improve traffic operations. His research is advancing our understanding of cooperative traffic control systems and contributes to the development of future mobility systems, including connected and automated vehicles.
