Transportation mode choice is often expressed in terms of models which assume rational choice; psychological case studies of mode adoption are comparatively rare. We present findings from a study of the psychology of adoption for sustainable transportation modes such as bicycles, car sharing, and mass transit. Case studies were conducted with current and former participants in PSU’s ‘Passport Plus’ transit pass program, as well as a longitudinal cohort study of first-time winter bicycle commuters. Composite sequence analysis was used to construct a theory of the adoption process for these modes. Our findings suggest that mode evaluation is cognitively distinct from mode selection and has different information requirements. We conclude that public and private organizations could improve the adoption rate for these modes by tailoring their communication strategies to match the commuter’s stage of adoption.

APPLICATIONS HAVE CLOSED

Registration is open to female and female-identified students in Oregon who will be current high school students in the Fall of 2018.

For the third year in a row, we're hosting an Oregon Summer Transportation Institute (OSTI) for high school girls. This two-week residence camp offers any student entering the 9–12 grade who identifies as female an immersive introduction to the workings of the Portland transportation system.

Half of each day is spent in the classroom hearing from PSU faculty and guest lecturers from ODOT, the FHWA, the Portland Bureau of Transportation, TriMet, the Port of Portland, and various other public and private transportation agencies that operate in the Portland metro area.

The other half is spent outside, in field tours of Portland’s transportation infrastructure and public spaces. Planners, engineers and designers come from all over the country to see Portland’...

It has been nearly 25 years since non-motorized modes and non-motorized-specific built environment measures were first included in the regional travel demand models of metropolitan planning organizations (MPOs). Such modeling practices have evolved considerably as data collection and analysis methods improve, decisions-makers demand more policy-responsive tools, and walking and cycling grow in popularity. Many models now explicitly consider the unique characteristics of walking travel, separate from travel by bicycle. As MPOs look to enhance their models’ representations of pedestrian travel, the need to understand current and emerging practice is great.

This project presents a comprehensive review of the practice of representing walking in MPO travel models. A review of model documentation determined that – as of mid-2012 – 63% (30) of the 48 largest MPOs included non-motorized travel in their regional models, while 47% (14) of those also distinguished between walk and bicycle modes. The modeling frameworks, model structures, and variables used for pedestrian and non-motorized regional modeling are described and discussed. A survey of MPO staff members revealed barriers to modeling non-motorized travel, including insufficient travel survey records, but also innovations being implemented, including smaller zones and non-motorized network assignment. Finally, best practices in...

15 years of travel surveys at portland transit oriented development
 

PRESENTATION ARCHIVE

OVERVIEW

Since 2005, Portland State University has periodically surveyed occupants of recently developed  higher-density and mixed-use projects near transit, often referred to as Transit-Oriented Developments (TODs). The general objectives of the surveys were to better understand actual transit use, among other factors, of residents in these buildings. Between 2005 and 2018, the research team surveyed residents of nearly 50 TODs. With funding from Metro and the National Institute for Transportation and Communities, the research team carried out a two-pronged study drawing on this wealth of data. First, we explore geographic differences within the Portland region in terms of travel behavior and attitudes of TOD residents, including differences between TODs within the city of Portland, in eastside suburbs, and in westside suburbs. Second, we conducted a second wave of surveys for select TODs to understand if travel behavior or attitudes changed over time, particularly as neighborhoods surrounding the buildings were built up. In this webinar, we will present select findings from both aspects of the study.

THE TOPIC 

Container cargo shipping service returned to the Port of Portland in Oregon in January 2020 with the regular weekly SM Line service, following more than three years of no container shipping service. Following the global supply chain changes associated with COVID-19, the number of monthly vessel calls at the Port of Portland’s deep-water berth at Terminal 6 has increased regularly to 12 vessel calls in January of 2022. In March of 2022, the largest containership to transit the Columbia river – at 1,100 feet length with capacity of 8,200 containers – arrived at the Port of Portland.

The return of...

Oliver Smith (USP PhD) - Peak of the day or the daily grind? Commuting and subjective well-being

To understand the impact of daily travel on personal and societal well-being, measurement techniques that go beyond satisfaction-based measures of travel are used. Such metrics are increasingly important for evaluating transportation and land-use policies. This study examines commute well-being, a multi-item measure of how one feels about the commute to work, and its influences using data from a web-based survey that was distributed to Portland, Oregon, U.S.A. workers. Valid surveys (n=828) were compiled from three roughly equally sized groups based on mode: bike, transit and car users. Average distances between work and home varied significantly among the three groups. Descriptive results show that commute well-being varies widely across the sample. Those who bike to work have significantly higher commute well-being than transit and car commuters. A multiple linear regression model shows that along with travel mode, traffic congestion, travel time, income, health, job satisfaction and residential satisfaction also play important individual roles in shaping commute well-being. While more analysis is needed, these results support findings in previous research that commuting by bike enhances well-being while congestion detracts from well-being. Implications...

OVERVIEW

This webinar will introduce you to the concept of the Community Transportation Academy (CTA), a model which has been operating in Portland for over 30 years in the form of the Portland Traffic and Transportation (PTT) class. Now catching on in other cities, the project team recently implemented the Wasatch Transportation Academy (WTA) in Salt Lake City. The presenters also include key stakeholders (and guest lecturers) in the WTA, and the PTT instructor. The presentation will include discussions about why CTAs can be good for both community members and transportation agencies/practitioners, and how you can bring a CTA to your city.

KEY LEARNING OUTCOMES

  • How to make interactions between community members and transportation agencies more effective
  • How to increase human capital and community capacity by teaching community members how and where they can engage in transportation decision-making processes
  • Lessons from transportation...
