Cycling By Choice Or Necessity? Exploring The Gender Gap In Bicycling In Oregon, Patrick Allen Singleton

PSU Transportation Seminars

In Oregon, as elsewhere in the US, a greater percentage of men bicycle than women. This study illuminates the gender gap in bicycling by exploring differences in bicycling among women and men in Oregon. A one-day statewide travel survey of over 30,000 adults was examined. Comparisons between individual, household, and trip and activity characteristics for people grouped by gender (women vs. men) and bicycling (made a bicycle trip or normally commuted by bicycle vs. did not bicycle) were assessed using chi-squared tests of independence. Many significant differences were found. In particular, women living alone, not working, without a high-school degree, …

Evaluation Of An Electric Bike Pilot Project At Three Employment Campuses In Portland, Oregon, Nicholas Kobel

PSU Transportation Seminars

Electric bicycles are growing more popular every year, but little research yet exists on how they might play a role in our transportation systems. Much of the literature on biking for transportation focuses on the standard bicycle and infrastructure to support it, less so on the vehicle itself. This project evaluates an electric bicycle program at three Kaiser Permanente campuses in the Portland, Oregon metropolitan area and examines participants' impressions of e-bikes.

Results support the hypothesis that e-bikes allow for a broader participation in cycling and for existing cyclists to go to more places.

Utilizing High Resolution Bus Gps Data To Visualize And Identify Congestion Hot-Spots In Urban Arterials, Nicholas B. Stoll

PSU Transportation Seminars

The research uses high resolution bus data to examine sources of delay on urban arterials. A set of tools were created to help visualize trends in bus behavior and movement, which allowed for larger traffic trends to be visualized along urban corridors and urban streets. By using buses as probes and examining aggregated bus behavior, contoured speed plots were used to understand the behavior of roadways outside the zone of influence of bus stops. These speed plots can be utilized to discover trends and travel patterns with only a few days’ worth of data. Congestion and speed variation can be …

Assessing Travel Plans For Residential Developments, Geoff Rose

PSU Transportation Seminars

A ‘travel plan’ is a travel demand management strategy that contains a package of site-specific measures designed to manage car use and encourage the use of more sustainable transport modes. Much of the existing literature on travel plans focuses on their application in workplaces and schools. Travel plans can be required for new residential developments as part of the land use planning and approvals process. However, there is limited understanding of the extent to which they have influenced travel behaviour. This presentation focuses on the assessment of travel plans developed for new residential apartment developments in Melbourne, Australia. Consideration is …

Managing User Delay With A Focus On Pedestrian Operations, Andrew Kading

PSU Transportation Seminars

Across the U.S, walking trips are increasing. However, pedestrians still face significantly higher delays than motor vehicles at signalized intersections due to traditional signal timing practices of prioritizing vehicular movements. This study explores pedestrian delay reduction methods via development of a pedestrian priority algorithm that selects an operational plan favorable to pedestrian service, provided a user defined volume threshold has been met for the major street. This algorithm, along with several operational scenarios, were analyzed with VISSIM using Software-In-The-Loop (SITL) simulation to determine the impact these strategies have on user delays. One of the operational scenarios examined was that of …

The Importance Of Housing, Accessibility, And Transport Characteristic Ratings On Stated Neighborhood Preference, Kristina Marie Currans

PSU Transportation Seminars

Travel demand models commonly lack the ability to understand how changing residential preferences influence future housing, land use, and transportation policies. As communities struggle to address social challenges related to increased economic uncertainty, transportation and land use planning have become increasingly centered on assumptions concerning the market for residential environments and travel choices. In response, an added importance has been placed on the development of toolkits capable of providing robust and flexible models to aid in understanding how differing assumptions contribute to a set of planning scenarios and how future residential location decisions may be made.

In this study, we …

An Activity-Related Land Use Mix Construct And Its Connection To Pedestrian Travel, Steven R. Gehrke

PSU Transportation Seminars

Land use mix is a central smart growth principle connected to active transportation. This presentation describes the indicators of local land use mixing and their association with pedestrian travel in Oregon’s Willamette River Valley. It argues that land use mix is a multidimensional construct reflected by the complementarity, composition, and configuration of land use types, which is positively linked to walk mode choice and home-based trip frequency. Findings from this study underline the conceptual and empirical benefit of analyzing this transportation-land use interaction with a landscape pattern measure of activity-related composition and spatial configuration.

The presentation for this seminar was …

The Peer Network As A Context For The Socialization Of Academic Engagement, Linda Mary Newton-Curtis

Dissertations and Theses

The school environment is one of the primary contexts for children's social, emotional and cognitive development. While teachers are likely to be primarily focused on students' motivation and learning, for adolescents, one of the most enjoyable and important aspects of school life is likely to be centered around the time spent interacting with peers. It is well recognized that peers socialize one another but although many studies have examined the influence of peers on adolescents' risky behaviors far fewer have focused on the influence peers may have on individuals' positive behaviors. As a result this study focuses on academic development …

In Need Of A Long Welcome: Supporting The Integration Of Newcomers To Portland, Ann Curry-Stevens, Anne Sinkey

Center to Advance Racial Equity Publications and Reports

Portland’s newcomer communities bring considerable assets to the region. Their legacy is one of potential untapped, as they face significant exclusion from economic and civic life, and an environment that is full of challenges without sufficient supports to help them navigate forwards into the fabric of Portland. This report, prepared in partnership with the New Portlander’s Policy Council, surfaces the history of newcomer conditions in the region, including a policy history, alongside a literature review on best practices for newcomer integration, new quantitative data on the patterns of newcomer experiences, a chapter on myths and myth-busting, and insights into five …

Can Expert Testimony Sensitize Jurors To Variations In Confession Evidence, Kelsey S. Henderson, Lora M. Levett

Criminology and Criminal Justice Faculty Publications and Presentations

Confession evidence can be extremely damaging in the courtroom; jurors are more willing to convict based on the presence of a confession than eyewitness evidence and character testimony (Kassin & Neumann, 1997). To date, no research has examined whether jurors notice variations in confession evidence based on whether the confession is consistent or inconsistent with the crime evidence (a likely low quality confession). In Study 1, mock jurors read a trial summary in which a suspect’s confession was consistent or inconsistent with other case facts. Jurors were marginally more likely to convict if the confession and case facts were consistent …

Leadership Positioning Among U.S. Firms Investing In China, Rossitza B. Wooster, Donna L. Paul

Economics Faculty Publications and Presentations

This study investigates leadership positioning by U.S. firms in China using the awareness, motivation, capability (AMC) perspective. We define leadership as first in industry to invest in China, and find that leaders have characteristics associated with higher AMC, evidenced by pre-existing multinational experience, higher product market orientation, smaller scale of operations, and higher input cost structure. Notably, the motivation to lower input costs and the prior capability in multinational operations mattered only for the first wave of firms leading industry investment earlier in time, while firms with smaller scale of operations exhibited a preference to lead investment in less popular …

Optimal Design Of Compact And Functionally Contiguous Conservation Management Areas, Hayri Önal, Yicheng Wang, Sahan T.M. Dissanayake, James D. Westervelt

Economics Faculty Publications and Presentations

Compactness and landscape connectivity are essential properties for effective functioning of conservation reserves. In this article we introduce a linear integer programming model to determine optimal configuration of a conservation reserve with such properties. Connectivity can be defined either as structural (physical) connectivity or functional connectivity; the model developed here addresses both properties. We apply the model to identify the optimal conservation management areas for protection of Gopher Tortoise (GT) in a military installation, Ft. Benning, Georgia, which serves as a safe refuge for this ‘at risk’ species. The recent expansion in the military mission of the installation increases the …

Comparing Unmanned Aerial Systems (Uas) Structure-From-Motion Digital Surface Modeling To Laser Imaging Detection And Ranging (Lidar), Joshua D. Schane

Geography Masters Research Papers

UAS (unmanned-aerial systems) mapping is an emerging technology in spatial science. UAS, more informally referred to as “drones,” are small, radio-controlled or autonomous aerial platforms outfitted with camera sensor systems that can be deployed to fly missions for mapping terrain and structures. With the use of a photogrammetry technique called structure-from-motion, overlapping aerial images can be developed into high-resolution spatial data (< 5-cm). These data are georeferenced by GPS location information assigned to aerial targets which act as ground-control points (GCPs). This research explores the accuracy of the UAS-derived digital surface model (DSM) as it relates to a LIDAR DSM of the same study area in St. Helens, Oregon.

The site that was chosen to be mapped was a large wastewater treatment plant, with surrounding natural areas, residential, and industrial properties. The site was mapped using a small quadcopter-style UAS which was programmed autonomously; the overlapping aerial …

Stewarding Our Mountains: A Program Evaluation Of Place-Based Service Learning On The Appalachian Trail, Bonnie Jean Harvey

Anthropology Theses

Appalachians’ relationships with the environment alter over time due to political, economic, and ecological factors. These changing relationships, for instance rural agrarian livelihoods shifting to urban contexts, can influence how an individual perceives personal responsibility in regional environmental stewardship, such as caring for and preserving local ecology. Observing that recent shifts resulted in less perceived youth stewardship for the Appalachian Trail (AT), the Appalachian Trail Conservancy (ATC) created the Trail to Every Classroom (TTEC) program in 2006. The TTEC program attempts to foster stewardship through the practice of place-based service learning - a diversification of education where youth learn through …

Potentially Traumatic Experiences And Sexual Health Among Orphaned And Separated Adolescents In Five Low- And Middle-Income Countries, Christine L. Gray, Kathryn Whetten, Lynne C. Messer, Rachel A. Whetten, Jan Ostermann, Karen O'Donnell, Nathan M. Thielman, Brian W. Pence

Community Health Faculty Publications and Presentations

Orphans and separated children (OSC) are a vulnerable population whose numbers are increasing, particularly in sub-Saharan Africa and Asia. Over 153 million children worldwide have lost one or both parents, including 17 million orphaned by AIDS, and millions more have been separated from their parents. As younger orphans enter adolescence, their sexual health and HIV-related risk behaviors become key considerations for their overall health. Importantly, their high prevalence of exposure to potentially traumatic events (PTEs) may put OSC at additional risk for adverse sexual health outcomes. The Positive Outcomes for Orphans study followed OSC randomly sampled from institution-based care and …

Halprin Sequence Reimagined, Andrea Villarroel, Nate Miller, Kris Decker, Foster Gough, Scott Robinson

Urban Design Workshop

The Halprin Sequence is a series of underutilized green spaces in the heart of Portland, Oregon. Once a booming attraction, as time has past and the city has grown, the Halprin Sequence has been forgotten amongst the towers. With a rich history in urban development and design, the Halprin Sequence could offer much more to the people of Portland than it is currently. The surrounding street of Fourth Avenue is also underutilized. The street is primarily used by automobiles, and the sidewalks are not pleasant to walk through.

For a green space network, the Halprin Sequence is in an ideal …
