Zifeng (Lilian) Wu, PhD
Lilian is a transportation planner and engineer who joined Kittelson with five years of research experience and four years of consulting work in multimodal transportation planning, traffic simulation and operation studies, safety analysis, innovative intersection design, and data-driven decision-making support. Lilian has developed and updated travel demand models using TransCAD and VISUM for multimodal networks of varied sizes. Her traffic operations experience includes interchange ramp intersection improvement studies with innovative intersection design—diverging diamond interchange, restricted crossing U-turn intersection, displaced left-turn intersection—using VISSIM, Synchro, and other major software tools. She is expert in the application of advanced statistical modeling methods to analyze crash data and evaluate the effectiveness of safety improvement strategies.
Lilian holds a Ph.D. in civil engineering from the University of Nebraska–Lincoln, where her research projects focused on transportation system reliability evaluation, real-time travel time prediction, outlier identification for data collection, and highway-railway at-grade crossing studies. She has coauthored several peer-reviewed journal articles and conference papers and has given technical presentations at local- and national-level conferences. She has also served as a peer reviewer for both domestic and international journals.
When not in the office, Lilian might be found working out at the gym, translating (from Chinese) and writing papers, watching figure skating, or heading out to visit friends.
