As urban areas across the country are investing in bicycle and pedestrian infrastructure to promote environmentally sustainable transportation and to develop livable communities, many have pointed to improvements in environmental quality, economic development and public health as potential positive outcomes. While these outcomes of active transportation infrastructure are relatively well documented, it is also known that both transportation and environmental...Read more
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. First, a critical literature review strengthens the PUT concept. Next, the two main PUT aspects—travel-based multitasking and subjective well-being in the travel domain—are analyzed, and potential determinants examined. Finally, an integrated choice and latent variable model reveals significant associations between PUT measures and commute mode choices. Findings contribute to travel behavior research and knowledge and offer implications for...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. Both governments have numeric goals for the proportion of trips to be made by walking, bicycling, transit, shared vehicles, working at home and driving alone. Indeed, the City of Portland desires that by 2035 no more than thirty percent of commute trips be made by people driving alone. Similar policies have driven transportation planning in the city and region for decades.
To understand if these policies will be effective it's necessary to understand whether their antecedents have been effective. The Portland region has been investing in transit, bicycling and walking for more than two decades? Are we moving the needle? Have we been effective?
Roger's presentation will take a look at regional data for the period 2000-2014 to assess the effectiveness of our efforts and use that information to suggest pathways forward.
Roger Geller has been Portland, Oregon’s bicycle coordinator since 2000 and has been...Read more

Oregon, and Portland in particular, is internationally known for its love for bikes. Not only does the region have some of the highest bike ridership in the nation but the Oregon bike manufacturing industry is quickly growing as well. Oregon’s electric bike (e-bike) market is also growing, but little data are available on the potential market and e-bike user behavior and interest.
Only a limited amount of research has explored the potential new market segments for e-bikes and the economic, operational, safety, and transportation issues surrounding e-bikes in the United States. This webinar will present findings from a research project evaluating e-bike use at three Kaiser Permanente employment centers in the Portland region.
The project's primary goal was to test user acceptance of electric-assist folding bicycles as a commuting solution.
What makes Americans’ travel behaviors so different from that of their West European counterparts? Longer trip distances? Higher rates of licenses and auto-ownership? A culture and economy that depends on the automobile industry? According to visiting scholar Ralph Buehler, none of these explain the differences in mode splits.
In partnership with Students in Transportation Engineering and Planning (STEP), Portland State University recently hosted visiting scholar Ralph Buehler at the Friday Transportation Seminar series. Dr. Buehler traveled west from Washington, D.C. where he is an Assistant Professor in Urban Affairs and Planning at Virginia Tech’s Metropolitan Institute. Dr. Beuhler’s research and expertise is in multimodal planning and travel behaviors, with a focus on Western Europe and North America.

Dr. Buehler’s presentation, titled “Making Urban Transport Sustainable: Comparison of Germany and the US,” poked holes in many of the common theories explaining why Americans are more likely to use their cars for all their travel needs. Instead, he noted that, “transport policies have to explain the difference [in mode shares] over time, including the changes that have happened in Germany and those that have not happened in the US. ” His research has led him to identify four major policy...Read more
Bicycle commuters represent a significant chunk of business consumers in Portland, Ore., one of America's most bike-friendly cities. OTREC research in the past year has provided data on how cyclists and other mode users patronize local businesses.
