Dr. Saeed Mohammadian is a postdoctoral research fellow in Transport Engineering. His primary research is on understanding freeway traffic flow dynamics and their safety implication with a special focus on the role of human factors. As part of his doctoral work, he has conducted critical meta-research on the state-of-the-art of macroscopic traffic flow modelling, from both theoretical and practical perspectives. The central part of his doctoral thesis develops unifiable mathematical models of traffic flow dynamics and rear-end crashes and presents new insight into the role of human factors on complex traffic phenomena and traffic safety.

His main work at UQ involves conducting research on driver interactions with connected and automated vehicles and studying the implications for both congestions and crashes. He is currently involved in several research projects related to freeway traffic flow modelling and control and safety assessment. His research outcomes can be explicitly utilized in traffic control research for moving towards faster and safer roads.
