Summary: The declining rates of physical activity among children, particularly adolescent girls, are well-documented, yet there has been insufficient research into the attitudes about health behaviors, particularly active travel, of the children themselves. Tara's research explores attitudes about active transportation among children aged 4-17 years and examines how perceived ability, self-efficacy, and sensitivity to certain environments or facilities vary across gender and age of the children. She utilises data from the Family Activity Study, a multi-year longitudinal intervention study in Portland, Oregon, in which 490 children answered surveys regarding their attitudes, perceptions, and behaviors about traveling by walking, bicycling, or being in a car.

OVERVIEW
The National Street Improvements Study, conducted by PSU in conjunction with PeopleForBikes and consulting firm Bennett Midland, researched the economic effects of bicycle infrastructure on 14 corridors across six cities — Portland, Seattle, San Francisco, Memphis, Minneapolis and Indianapolis. The study found that improvements such as bicycle and pedestrian infrastructure had either positive or non-significant impacts on the local economy as measured through sales and employment. In this webinar, lead researcher Jenny Liu will share the results of the investigation and the unique methodology for investigating these economic outcomes.

This webinar is based on a study funded by the National Institute for Transportation and Communities (NITC) and the Summit Foundation, and conducted at Portland State University. Read more about the research: ...
Read moreTransportation 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.

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...

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’...

OVERVIEW
Planners and decision makers have increasingly voiced a need for network-wide estimates of bicycling activity. Such volume estimates have for decades informed motorized planning and analysis but have only recently become feasible for non-motorized travel modes.
Recently, new sources of bicycling activity data have emerged such as Strava, Streetlight, and GPS-enabled bike share systems. These emerging data sources have potential advantages as a complement to traditional count data, and have even been proposed as replacements for such data, since they are collected continuously and for larger portions of local bicycle networks. However, the representativeness of these new data sources has been questioned, and their suitability for producing bicycle volume estimates has yet to...

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...
