Dillon Fitch

Co-Director Dillon Fitch, Ph.D.
Dillon Fitch studies travel behavior and transportation planning and occasionally teaches in the Department of Environmental Science and Policy. Through field experiments, travel surveys, and crowdsourced data, Dillon’s recent research has focused on how road environments influence people’s bicycling attitudes and behavior. His current work explores the role of bike shares and other micromobility services on changing travel behavior. He also develops tools to improve planning for bicycles and emerging small vehicles.

Susan Handy

Co-Director Susan Handy, Professor
Dr. Susan Handy's research focuses on the relationships between transportation and land use and on strategies for reducing automobile dependence. Her recent work includes a series of studies on bicycling in Davis, including an exploration of the formation of attitudes towards bicycling, a study of factors affecting bicycling to high school, and the use of electric-assist bicycles.  She recently completed projects for the California Air Resources Board and Caltrans on the impacts of “smart growth” strategies on vehicle travel.
