Biography

Sahar's research investigates driver behavior using human/machine learning and agent-based modeling techniques. She has researched driver decision prediction models at the onset of yellow at signalized intersections, and developed a novel safety surrogate measure applying intelligent transportation systems (ITS) technologies. She has conducted research related to traffic safety evaluation and analysis by installation of a real-time data collection and safety improvement system at signalized intersections to address dilemma zone safety issues with control solutions. She is also experienced in experimental design of naturalistic behavior studies as well as traffic safety scenario development and implementation in driving simulator. Her lab at SDSU features a driving simulator which is used to examine new safety related ideas that are dangerous or time/money consuming to be examined in the real world. In another stream of work, she has studied infrastructure-based safety systems such as innovative delineation systems to increase road users' safety. She is presently working on a human factor study researching the impacts of vehicle to infrastructure communication on driver behavior in a connected vehicle environment.
