About John Sangster
Dr. Sangster joined the department in Fall 2015 as an assistant professor. He received his Ph.D. and MS from Virginia Tech in 2015 and 2011, respectively. Prior to his return to graduate school, he worked as a practicing engineer for seven years in Chicago and New Hampshire. His practice experience focused on roadway design and traffic engineering, with his dissertation research combining the two, bridging research and practice on the topic of vehicle operations at alternative intersections.
Research by Dr. Sangster and his graduate students focuses on modeling and simulation of traffic scenarios to better understand the operational and safety impacts of our roadway design decisions. Specific ongoing research topics include the analysis of best practices for road diet implementations in Nebraska, comparison of analysis tools to assess operations at roundabouts, exploration of capabilities and limitations of various commercial traffic simulation software applications, and exploratory research investigating driver behavior analysis utilizing a driving simulator.
Dr. Sangster says that his most rewarding work as a faculty at UNL has been to apply his experience to bridge the gap between theory and practice within the courses he teaches. By providing the foundational academic background in parallel with realistic situated design experiences, he works to ease the transition for graduates preparing to enter the workplace, helping them be more successful in their future careers. He was recognized “for his commitment to education and the impact he has made on his students” in November of 2015 with an Omicron Delta Kappa Professor of the Month award.
