The Portland State University Department of Civil and Environmental Engineering is pleased to announce Steven Gehrke's PhD Dissertation Defense: "Land Use Mix and Pedestrian Travel Behavior: Advancements in Conceptualization and Measurement."

Adviser: Dr. Kelly Clifton

Urban policies encouraging pedestrian travel are often rooted in land development strategies, which are intended to promote greater efficiencies in the built environment. Land use mix, an important smart growth tenet, is one such strategy beholding of lasting urban planning and public health benefits. Still, no consensus exists about the conceptualization and measurement of land use mix or the magnitude of its connection with pedestrian travel. This dissertation is comprised of three empirical studies that explore this topic in detail.

NITC dissertation fellow Steven Gehrke is a Ph.D. candidate and graduate research assistant in the department of civil & environmental engineering at Portland State University. Steven's doctoral research centers on an improved understanding of the relationships between nonautomotive travel behaviors and the temporal mixing of activity locations. He previously received a master’s degree in community planning from the University of Maryland and a B.S. in geography from New Mexico State University. His research explores the transportation-land use connection, with a primary focus on better understanding the built environment determinants of active transportation. He has published articles in transportation journals studying the travel outcomes of residential location decisions, work-based travel behavior, and built environment measurement. For his dissertation research, Steven is investigating the impacts of land use mix on pedestrian travel in Oregon’s Willamette River Valley. In 2015, he was awarded a NITC dissertation fellowship and the Stan Czamanski Prize from the Regional Science Association International for his research proposal.
