The Portland State University Department of Civil and Environmental Engineering is pleased to announce Patrick Singleton's PhD Dissertation Defense: "Exploring the Positive Utility of Travel and Mode Choice."
Adviser: Dr. Kelly Clifton
The “positive utility of travel” (PUT) concept suggests that travel may provide benefits and be motivated by factors beyond simply reaching a destination. This dissertation explores the PUT idea theoretically and empirically, using the results of a novel 2016 survey of nearly 700 commuters in the Portland, OR, region.

Findings contribute to travel behavior research and knowledge and...Read more
The City of Portland and the Metropolitan Region have strong policies in place to encourage transportation through means other than the single-occupancy vehicle.
