Peihang Li Receives PPTG Student Research Grant

HIACE Lab Ph.D. student Peihang Li, supervised by Dr. Nade Liang, has received the PPTG Student Research Grant from the Perception and Performance Technical Group of the Human Factors and Ergonomics Society (HFES). The grant provides $500 in support of Peihang’s ongoing research in transportation safety and human factors. As part of the award, he will present his work during the PPTG social event at the ASPIRE conference and contribute a summary of the study to the PPTG newsletter.

The funded proposal, titled “Risk Perception and Driver Adaptation in Dynamic Traffic Environments,” investigates how drivers perceive and adapt to transitions in traffic density and speed conditions. Using a driving simulator and physiological measures such as eye-tracking and galvanic skin response, the study aims to understand how shifts in perceived risk influence driver behavior and decision-making. The project also explores computational approaches—such as Linear Mixed-Effects Models and Long Short-Term Memory (LSTM) networks—to model the time-varying relationship between physiological responses and behavioral adaptation in complex driving environments.
