Rajaram Bhagavathula is a Senior Research Associate in CIBSS at VTTI. His research is focused on the effect of the built environment on road user safety. Specifically, he aims to understand the safety effects of treatments in the built environment (e.g., lighting and signage) on driver behavior. He is currently a PI on research studies examining the effects of roadway lighting on driver health, alertness, and visibility. He is also a lead experimenter in a series of projects related to roadway lighting, including intersection lighting, the spectral effects of roadway lighting, work zone lighting, conspicuity of cyclists, and pedestrian safety at roundabouts. Dr. Bhagavathula is also a member of IES’s Roadway Lighting Committee. Dr. Bhagavathula received a Ph.D. in Human Factors and Ergonomics from Virginia Tech with a focus on driver visual performance and roadway lighting, specifically at intersections.
