Associate Professor of Transportation Engineering
Timothy J. Gates received his Ph.D. from the University of Wisconsin-Madison in 2007 and was on the faculty at Wayne State University from 2007-2015. Gates has extensive research experience in traffic safety (including pedestrians and bicyclists), traffic control devices, driver behavior, roadside corridor planning and transportation economics. Since 2007, he has served as principal investigator or co-PI on 72 competitive grants with total collective extramural funding exceeding $13.3 million.
Gates’ primary area of expertise is evaluating behavioral effects associated with various countermeasures or policies related to traffic safety or traffic operations, including speed limits, rumble strips, traffic control device enhancements and pedestrian/bike treatments. In this realm, he has led or co-led projects in the assessment of speed limit policies, signal timing strategies (including dilemma zones and railroad interconnections), work zone safety strategies, visibility of signs and marking treatments, development of safety performance functions, and evaluating countermeasures such as rumble strips, cable barriers and curve warning technologies. His work has been acknowledged with numerous awards, including three Best Paper awards from the Transportation Research Board Committee on Pedestrians and Committee on the Operational Effects of Geometrics.
