Comprised of members from Appalachian State University, NC A&T University, NC Central University, UNC Charlotte, the UNC-Chapel Hill Department of City and Regional Planning and the UNC Highway Safety Research Center, TSAP is a consortium of partners encompassing diversity in disciplines and representation. We are a multidisciplinary group of traffic safety research professionals, human factors experts, planners, public administrators, educators, computer scientists/systems engineers, and civil and electrical engineers who share a collaborative mindset.
Our team draws upon and leverages extensive national transportation experience, including extensive professional networks established through three University Transportation Centers—the Collaborative Sciences Center for Road Safety (CSCRS),Center for Advanced Transportation Mobility (CATM) and Mineta Consortium for Transportation Mobility (MCTM)—to benefit all North Carolinians. Additionally, NCCU brings extensive experience working with individuals with disabilities and App State is focused on rural and mountain transportation issues, two additional perspectives that further round out the consortium’s diverse research portfolio.
Randa Radwan is the director of the UNC Highway Safety Research Center. She has over 25 years of experience in transportation safety and vehicle crashworthiness research, including vehicle safety performance and advanced technologies, and fostering international partnerships with automakers, safety regulators, and other researchers.
TSAP Associate Director
Maranda McBride is the director of the Transportation Institute at North Carolina Agricultural and Technical State University and the director of the Center for Advanced Transportation Mobility (a University Transportation Center funded by the U.S. Department of Transportation). Her research revolves around human-machine systems engineering, particularly interface design issues, and includes topics related to highway safety and aviation.
Srinivas S. Pulugurtha is currently working as Professor & Research Director of the Department of Civil & Environmental Engineering at the University of North Carolina at Charlotte (UNC Charlotte). He is also currently directing the Infrastructure, Design, Environment and Sustainability (IDEAS) Center on UNC Charlotte’s campus. Dr. Pulugurtha has experience working in diverse fields of transportation. These fields include traffic safety & operations, transportation system planning, Intelligent Transportation Systems (ITS), Geographic Information Systems (GIS) applications, data analytics and visualization, Internet applications, artificial intelligence (AI) techniques, and operations research applications.
Elizabeth Shay is an associate professor in the Department of Geography and Planning at Appalachian State University. Her teaching and research in city and regional planning focuses on transportation and land use, travel behavior and active travel, transportation equity, community development, and rural resilience.
William Wiener, PhD
TSAP Associate Director
William Wiener serves as the Brenda Brodie Endowed Chair and Professor at the North Carolina Central University training program in Visual Impairment. He is an authority on travel by persons with disabilities and has served as coordinator of university programs at three universities that prepare instructors who teach independent travel to people who are blind or have other disabilities. He is the main editor of the most widely used textbook in the field and an Associate Editor for the Journal of Visual Impairment and Blindness.
Tabitha Combs is a scholar of transportation planning and policy. She has expertise in transport and land use planning, the built environment-travel behavior connection, equity impacts of new mobility innovations, and transport planning in developing contexts, with a particular focus on social and environmental impacts of transport policies. Her overarching research goals are to expand our knowledge of the environmental determinants of travel behavior and vehicle use, and to apply that knowledge to support efforts of decision-makers to create more sustainable, healthy, socially just communities.
Sean Tikkun serves as an Assistant Professor at NC Central University in the Visual Impairment Training Program. He has served as a Subject Matter Expert in the domain of Assistive Technology and assisted in launching the area for ACVREP. Dr. Tikkun has over 15 years of experience teaching in the areas of mathematics, visual impairments, and orientation & mobility at all grade levels. He annually reviews consumer technologies for emerging impact to the population of individuals with visual impairments.
Hyoshin (John) Park serves as an Assistant Professor at North Carolina A&T State University. His focus areas include distributionally robust optimization-based active sensing for Transportation Systems, previous projects by the National Science Foundation (NSF), the U.S. Department of Transportation (USDOT), and the U. S. Department of Energy (DOE). He is a member of TRB’s Subcommittee for the Emerging Technologies in Network Modelling (TRB ADB30) and a member of ASCE T&DI Artificial Intelligence (AI) Committee. Dr. Park’s academic efforts include the development of an online transportation certiﬁcate at NCA&T. He teaches in multiple departments that feature cross-listed transportation classes for modeling, visualization, optimization, and simulation of transportation systems, demand modeling, and transportation network models.
Michael Clamann is the senior human factors engineer at the UNC Highway Safety Research Center. He has performed human factors research in industry and academia for over 18 years, and his areas of expertise include human-automation interaction and autonomous vehicle technology.
