About Christopher

Dr. Christopher Day is an affiliate researcher with the Center for Transportation Research and Education. His research focuses mainly on performance measures for highway transportation systems, particularly in their integration with transportation agency business practices. This research was supported in part by funding from National Academies projects, including NCHRP 3-122. The products of that research have seen widespread implementation in practice. Dr. Day’s work on automated traffic signal performance measures has been selected as a focus technology by the Federal Highway Administration’s Every Day Counts program and has been adopted by most traffic control equipment vendors in the US. 

Background


Dr. Christopher Day received bachelor’s and master’s degrees in physics at Ball State University in 2004 and 2006, and master’s degree and PhD in civil engineering from Purdue in 2007 and 2010. He is currently an assistant professor in Civil, Construction, and Environmental Engineering at Iowa State University. Before joining ISU, Dr. Day worked for about seven years as a senior research scientist in the Joint Transportation Research Program at Purdue University. His research has focused mainly on performance measures for highway transportation systems, particularly in their integration with transportation agency business practices.
