Lewis J. Lehe

Lewis J. Lehe is an Assistant Professor in the Department of Civil and Environmental Engineering at the University of Illinois at Urbana-Champaign (UIUC), specializing in Transportation Systems. He holds a Ph.D. from UC Berkeley (2016) and prior degrees from UC Berkeley, University of Leeds, and University of Pittsburgh. His research focuses on transportation pricing, urban traffic dynamics, and the economic implications of transportation policies.

Lehe's work includes groundbreaking studies on congestion pricing, parking policy impacts, and the integration of AI tools (e.g., GTFS Segments, TransitGPT) for transportation data analysis. He has been recognized with the Gordon F. Newell Award (2016) and Ove Arup Transport Prize (2012), and leads the Urban Traffic & Economics Lab (UTEL) at UIUC.

Notable research contributions include modeling hyperdemand in traffic systems, analyzing bus stop spacing, and evaluating taxation strategies for ride-hailing services. His recent articles explore transit pricing determinants, parking lot segmentation via NIR datasets, and equilibrium tolling paradoxes. Lehe advises graduate students like Ayush Pandey and Shirin Qiam, advancing topics such as bus route optimization and GTFS data benchmarking.
