Dr. Yazici's research interests can be broadly classified within two domains: transportation networks and mobility. His research is driven by questions and methodologies that are 1) networks/systems oriented, 2) data informed with particular emphasis on uncertainties, and 3) geared towards providing implementable planning and policy outcomes.

Dr. Yazici's transportation networks research addresses the need for models and metrics to assess the performance of transportation networks, as well as the safety, and economic and societal impacts related to transportation network disruptions. In his mobility research, Dr. Yazici addresses the reliability and safety of day-to-day transportation activities which have important economic, equity and quality of life implications. As technology transforms the transportation industry, Dr. Yazici has incorporated the emerging technologies into his research both as the sources of his big data research and as the driving force for his smart cities related research.

Dr. Yazici's research at Stony Brook Civil Engineering has been funded by both Federal and State agencies such as National Science Foundation (NSF), New York State and City Departments of Transportation (NYSDOT and NYCDOT), New York State Energy Research and Development Authority (NYSERDA).
