Changing the World

Highway crashes continue to claim lives, traffic congestion is rising, carbon emissions threaten our environment, and drivers are both concerned and excited about emerging technologies such as autonomous driving, connected vehicles, and cybersecurity. Dr. Qin and his team at the Safe and Smart (S2) Traffic Lab are exploring and identifying ways to save lives, save time, and safeguard the integrity of our transportation system.  We invite you to learn about our research, meet our lab staff, and get connected with our innovative community. We are always seeking new collaborators and exceptional students.

Safe and Smart (S2) Traffic Laboratory

The S2 Traffic Lab is a hub of innovation at one of America’s top research universities. In this community, professors, scientists and students make use of state-of-the-art techniques and methodologies to perform tangible and transformative research and studies. We offer research consulting services to facilitate scientific and informed decision making in areas including: Highway Safety; Human Factors and Driver Behavior Modeling; Traffic Operations and Control; Transportation Data Analytics; Mathematical Modeling of Urban Transportation Systems; Intelligent Transportation Systems; Geographic Information System (GIS) Application in Transportation; and impact analysis.


The S2 Traffic Lab is developing strategies and solutions to improve transportation systems in Wisconsin and beyond. Dr. Qin—the lab’s director and a professional engineer—leads initiatives in improving safety and efficiency in transportation systems by making use of statistical modeling, data analytics and engineering technologies to identify, analyze and evaluate factors contributing to crashes, congestion, and costs of travel.
