Examining Bicycle And Motorized Vehicle Speeds And Their Relationships In The Context Of Urban Roadways, Jaclyn Sue Schaefer

Dissertations and Theses

This thesis presents a compilation of papers exploring passenger car and bicycle speeds through their interactions with each other and with urban roadway factors.

First, following a concern raised in part of the traffic literature that a large mode shift toward bicycling may cause travel time delays and potentially exacerbate congestion instead of alleviate it unless bicycle lanes are installed, an empirical study detailing how the presence of bicycles on urban roads without bicycle lanes may affect passenger car speeds is presented. Pneumatic tube data from six predominantly low speed, low volume roads in Portland, Oregon were utilized to identify …

The Long-Haul: Buddhist Educational Strategies To Strengthen Students’ Resilience For Lifelong Personal Transformation And Positive Community Change, Namdrol Miranda Adams, Kevin Kecskes

Public Administration Faculty Publications and Presentations

For decades, community engagement scholars have built a robust body of knowledge that explores multiple facets of the higher education community engagement domain. More recently, scholars and practitioners from mainly Christian affiliated faith-based institutions have begun to investigate the complex inner world of community-engaged students’ meaning-making and spiritual development. While most of this fascinating cross-domain effort has been primarily based on “Western” influenced Judeo-Christian traditions, this study explores service-learning/community engagement themes, approaches, rationale, and strategies from an “Eastern” perspective based on the rich tradition of Tibetan Buddhism. This case study research focuses on curricular approaches, influences, and impacts of Buddhist …

The Electronic Hardware Music Subculture In Portland, Oregon, James Andrew Hickey

Dissertations and Theses

Music is relatively understudied as a geographic phenomenon, but recently there has been a shift in academic literature to understand the social, cultural and economic factors that determine music and its development in specific places. The purpose of this study is to examine the Electronic Hardware Music Subculture (EHMS) in Portland, why it thrives, and how it is linked to the local cultural economy. To do this, I used semi-structured, long form interviews with key members of the EHMS. These interviews, and my own observations, gave insight into what factors affect the success of members of the EHMS, and how …

Winning The Fight For Better Bus Service, Steven Higashide

PSU Transportation Seminars

The "right to the city" depends on the right to access the city, and U.S. regions are marked by profoundly unequal access. One of the clearest manifestations of this is the state of U.S. bus transit. Bus service is simple to improve and has vast potential to better people's lives, but has been constrained by the racist planning and politics that shape every American city.

How can we fulfill the promise of better buses and create abundant transit networks that expand access to opportunity? In this seminar, Higashide unpacks the elements of effective bus service – and cites examples from …

Aligning Food Environments With Institutional Values: A Mixed Methods Study Of Oregon Health Care Organizations, Elizaveta Walker

Dissertations and Theses

A major driver of the obesity epidemic is obesogenic food environments, characterized by nutrient-poor and energy-dense foods that saturate the collective physical, economic and sociocultural conditions that influence nutritional status. Food environments in organizations such as hospitals and public health agencies warrant special consideration given their health-focused mission. Improving food environments within health care settings has been highlighted by the Centers for Disease Control and Prevention (CDC) as one of seven key strategies to prevent obesity. However, most of the refereed literature examining healthy food environment policies (HFEPs) within hospitals focuses on the inpatient dietary environment, leaving a paucity of …

This is an opinion piece about a survey in Portland that reveals profound racial disparities even in basic answers about where people sleep.

Methodologies To Quantify Transit Performance Metrics At The System-Level Using High-Resolution Gps, Stop-Level, And Gtfs Archived Transit Data, Travis Bradley Glick

Dissertations and Theses

Performance metrics have typically focused at two main scales: a microscopic scale that focuses on specific locations, time-periods, and trips; and, a macroscopic scale that averages metrics over longer times, entire routes, and networks. When applied to entire transit systems, microscopic methodologies often have computational limitations while macroscopic methodologies ascribe artificial uniformity to non-uniform analysis areas. These limitations highlight the need for a middle approach.

This dissertation presents a mesoscopic analysis based around timepoint-segments, which are a novel application of an existing system for many transit agencies. For this research, routes are divided into a consecutive group of bus stops …

Racial Disparities In Traffic Enforcement, Mike Dolan Fliss

PSU Transportation Seminars

Law enforcement traffic stops are one of the most common entryways to the US justice system, with significant downstream impacts for both individuals and communities. Group-specific rates are typically based on jurisdiction resident populations; these rates, like many justice-system indicators, demonstrate race-ethnicity disparities. Residential-based rates implicitly assume race-ethnicity groups have equal vehicle access, equal driving volume, and that all driving occurs in resident’s jurisdictions. In contrast, surveys suggest Black non-Hispanic and Hispanic households have less access and drive less than white non-Hispanic households. Models incorporating US Census data and race-ethnicity driving factors from the 2017 National Household Travel Survey showed …

Home Resources Supporting Workplace Resources: An Investigation Of Moderated Intervention Effects From The Study For Employment Retention Of Veterans (Serve), Sarah Nielsen Haverly

Dissertations and Theses

Social support directly impacts psychological outcomes both within the home and work domains. Hammer and colleagues suggest that social support at work from supervisors is related to a number of positive workplace outcomes. Kossek et al. elaborated that social support from supervisors is additionally effective when it is tailored to the unique needs of workers (i.e., role demands). The Veteran Supportive Supervisor Training (VSST) educates supervisors how to better support former service-members employed within the civilian workplace. Additional sources of social support are also key to positive outcomes for workers. Research shows that support from a partner or spouse can …

Curating Equitable Transportation, Nikotris Perkins

PSU Transportation Seminars

Getting people and goods from here to there is central to the ways we live, work, and play in the United States. The transportation networks we create as planners, engineers, geologists, contractors, consultants, advocates, and citizens involve a multitude of decisions. These decisions have great impact on who can get where, when and how; often connected to our structures of social power. This seminar connects those dots, questions our ability to make change, and calls participants to be actively involved in a transportation system that is curated for those it targets: everyone.

Webinar: Bus Stops: Access And Equity, Keith Bartholomew

TREC Webinar Series

Improving bus stops by providing shelters, seating, signage, and sidewalks is relatively inexpensive and popular among riders and local officials. Making such improvements, however, is not often a priority for U.S. transit providers because of competing demands for capital funds and a perception that amenities are not tied to measurable increases in system effectiveness or efficiency. This webinar focuses on the role that bus stops play as the point of first contact between transit agencies and their potential riders, and how the quality of that contact can influence both ridership and accessibility for riders with mobility-related disabilities. The webinar will …

At The Intersection Of Safety + Race + Transportation, Charlene Mcgee

PSU Transportation Seminars

Transportation policies at the local, regional, state and national levels have a direct impact on urban land use and development patterns. Transportation intersects with multiple areas including public health, education, climate change, physical activity, health outcomes, build environment, violence, safety, social cohesion and the wellness of communities. For the health outcomes influenced by transportation, disparities exist by race, ethnicity, and socioeconomic status in Multnomah County. Disproportionate exposure to injury, air pollution, and noise contributes to inequitable burdens of injuries and chronic disease among race and ethnic groups. This is exacerbated by lack of access to safe places for active transportation …

Bus Stops Improvements Along Utah Corridor Increase Ridership And Ada Accessibility, Keith Bartholomew

TREC Project Briefs

A bus stop can be anything from a simple signpost stuck in the grass, to a comfortable shelter with seating and paved access to the sidewalk. For many U.S. transit agencies across the country, improving facilities at bus stops is a priority. But how much do these improvements actually affect ridership? A lot, it turns out. A new NITC study, co-funded by the Utah Transit Authority (UTA) and led by Keith Bartholomew of the University of Utah, found a 5.9% increase in boardings after improvements were made to a series of bus stops in Salt Lake City - compared to …

Public Housing With Services For Older Adults With Developmental Disabilities: Differences In Efficacy Among Asian And White Communities, Junghee Lee, William Donlan, Paula C. Carder, Leigh Grover, Insik Hwang, Younghwan Kim, Gretchen Luhr

School of Social Work Faculty Publications and Presentations

This study examined the efficacy of a culturally responsive housing with services model for Asian-American older adults and persons with developmental disabilities separately, and with both for an interaction effect. Study participants, including 278 Whites and 75 Asian Americans, lived in 10 properties of public housing with services in Portland, OR. All Asian-American participants (except four) were immigrants from China, Korea, and Vietnam, and were well connected through community-based health and social services that were delivered onsite and at a nearby center by staff members who were also immigrants from these three countries. Asian-American participants were older, very poor, with …

Incorporating Local Foods Into Low-Income Families’ Home-Cooking Practices: The Critical Role Of Sustained Economic Subsidies, Jennifer Gaddis, Amy K. Coplen, Molly Clark-Barol, Allea Martin, Claire K. Barrett, Lauren Lubowicki

Urban Studies and Planning Faculty Publications and Presentations

Alternative food practices, including farmers markets and CSAs, are often inaccessible to lowincome families. Subsidized CSAs and fruit and vegetable prescription programs have the potential to decrease food insecurity, increase fresh fruit and vegetable consumption, and generate better health outcomes. However, several challenges can limit logistics of distribution and an inability to cook from scratch due to a lack of kitchen infrastructure, time, or skills. In this paper, we investigate two dietrelated health programs conducted with community partners in Madison, Wisconsin, and Portland, Oregon. We used photovoice to evaluate and enhance these programs, which supplied lowincome participants with free or …

Case Studies Of Travel Demand Analysis On Transport Disadvantaged Communities, Tierra Bills

PSU Transportation Seminars

Travel Demand Models are the backbone of decision-making for public transportation infrastructure investment. Yet, critiques of these models with respect to their usefulness and performance for transport disadvantage communities are rare in the academic literature. These disadvantage communities may include (but are not limited to) low income travelers, transit dependents, un/underemployed, and the elderly. With the objective of promoting travel demand models that are better equipped for assessing transportation impacts for disadvantaged communities, this presentation highlights lessons learned from two case studies of applying travel demand analysis to understand the transportation accessibility of low income, elderly, and transit dependent communities. …

PSU Transportation Seminars

Eastern Washington University's Small Urban, Rural & Tribal Center on Mobility (SURTCOM) focuses on the mobility needs and challenges faced by tribal communities. In this presentation, SURTCOM Associate Director Margo Hill will examine the accessibility of tribal communities to basic necessities. These necessities include:

• Interstate Onramps
• Micropolitan Population Centers
• Metropolitan Population Centers
• Indian Health Service (IHS) Facilities
• Grocery Stores
• Department Stores
• Fast Food Restaurants

Destinations were chosen based on observed health disparities within the American Indian population (Jones, 2006), and the importance of accessibility to healthy foods found throughout the food desert literature.

Professor Hill will also discuss Missing and …

Dignity Infused Community Engagement In Los Angeles, Caro Vera, Kevin Ocubillo

PSU Transportation Seminars

In 2019, the LADOT Vision Zero Division launched the Vision Zero Dignity Infused Community Engagement (VZ DICE) strategy with the intent to transform the way the City engages with local communities. This planning process intentionally and holistically incorporates the viewpoints, lived experiences, and perspectives of those most impacted by a planning project and seeks to restore and atone for historic, systemic, and institutional injustices. A team of community partners, advocates, social scientists, artists, everyday residents, and technical experts came together to reach community residents in ways that reflect the local social, cultural, and racial/ethnic identity of a neighborhood. The strategy …

Biking While Black: How Planning Contributes To Unjust Policing, Jesus Barajas

PSU Transportation Seminars

Neighborhoods of color tend to be the most dangerous places for cyclists and other road users, a result in part of historic disinvestment and failure to provide basic infrastructure. Safety efforts to reduce crashes, like Vision Zero, have called for both increased investment, a qualified benefit for disenfranchised communities, and increased traffic enforcement, a response that is likely to place people of color in even greater harm based on extensively documented police injustice.

Reducing Vehicle Miles Traveled, Encouraging Walk Trips, And Facilitating Efficient Trip Chains Through Polycentric Development, Reid Ewing, Keunhyun Park, Sadegh Sabouri, Torrey Lyons, Keuntae Kim, Dong-Ah Choi, Katherine Daly, Roya Etminani Ghasrodashti

TREC Final Reports

Compact development can result in many benefits for communities and residents. Areas can connect compact developments through high-quality transportation options, creating a network of centers, or a “polycentric” region. This development pattern is very popular in Europe and is linked to significant benefits. Salt Lake County has organically developed several small centers, and with the right strategies could continue to fuel this kind of growth. The metropolitan planning organization (MPO) for the region, the Wasatch Front Regional Council, has been planning for polycentric development since the Wasatch Choice for 2040 Vision was released in 2010. Our research is aimed at …

Regional Transportation Goals: Reducing Sprawl Through Interconnected Centers, Reid Ewing

TREC Project Briefs

A “polycentric” region is a network of compact developments (centers) that are connected with each other through high-quality transportation options. As the antidote to sprawling suburbs, compact centers can encourage all the things that sprawl discourages: public health, environmental sustainability, social cohesion, and economic diversity. But how can metropolitan planning organizations ensure that their regional plans will actually meet these goals? Polycentric development has been advocated by urban and transportation planners for more than a decade. However, effective practice must be backed by solid research, and to date there has been little or no research that quantifies the transportation benefits …

An Equity Focused Study On The Trip Temporal Distributions Of Vulnerable Road Users, Santiago Espinosa Wild

Civil and Environmental Engineering Master's Project Reports

The United States is a megadiverse nation with a transportation system that, for decades, was designed to serve primarily able-bodied, white, male motorists. This legacy creates a situation in which varying socio-demographic groups experience the transportation system differently with contrasting safety, accessibility, and convenience outcomes. This project introduces descriptive statistics and binary logistic models that provide transportation professionals and policy makers with a quantitative understanding on how, why, and when certain socio-demographic groups are more likely to engage in a trip. This project provides tools to measure and understand the equity implications of a wide array of transportation policy decisions. …

The Role Of Bus Stop Features In Facilitating Accessibility, Keith Bartholomew, Ja Young Kim, Divya Chandrasekhar, Reid Ewing, Arlie Adkins, Samuel Jensen

TREC Final Reports

Although transit decision-makers and riders generally favor improving bus stops by adding shelters, benches, and similar features, it is unclear the impact such features have on transit demand and there has been little research that measures these impacts. This study examines the link between stop improvements and changes in stop-level boardings on scheduled-service buses and in ADA paratransit demand in the Salt Lake City, UT, metropolitan area between 2014 and 2017. The study also investigates current bus stop improvement practices of leading transit agencies nationwide. The study uses a number of quantitative and qualitative techniques, including propensity score matching, propensity …

Human Confusion: Why There Must Be Justice For Non-Humans, David Johns

Political Science Faculty Publications and Presentations

Over the last twelve millennia—since agriculture first emerged—humans have increased their exploitation and efforts to control other species and to colonize the Earth. Human on human hierarchy and colonization of other humans follows on the colonization of the natural world. The task of conservation is to undo that colonial relationship. We have been causing the extinction of other life-forms, including hominid species, since we left Africa at least 60,000 years ago. In the last 50 years, or just about two human generations, nearly 68% of all vertebrate animals have disappeared due to human activity (WWF 2020). Humans go into an …

An Investigation Of The Temporal Relationship Between Agitation And Sleep Disturbances, Emily Catherine Denning

Dissertations and Theses

Suicide rates in the United States have increased almost 30% since 1999, making it the tenth leading cause of death in the country. This problem is especially prominent for veterans of the U.S. Armed Forces, as veterans comprise 8.5% of the U.S. population, yet they account for 18% of all deaths by suicide. These increasing rates have spurred the need for a better understanding of suicide risk, especially for this high-risk group. Previous research has focused mostly on chronic risk factors, which are useful for identifying who from a population may be more likely to engage in suicidal behaviors, but …

A Daily Examination Of Anger And Alcohol Use Among Post-9/11 Veterans, James David Lee

Dissertations and Theses

Anger problems have been commonly reported among military service-connected individuals. Current estimates of self-reported anger issues among post-9/11 veterans are around 57%. Alarmingly, it's been reported that anger does not decrease over the course of the post-deployment period; left unmanaged, it has been associated with a higher risk for suicide, post-traumatic stress, and hazardous alcohol use. Heavy drinking within military-connected samples has also been a well-documented phenomenon. Recent findings suggest that service-connected individuals may cope with adversity and regulate emotions through alcohol use, which may put them at risk for developing alcohol use disorders. While some evidence has observed a …

Webinar: A National Scan Of Bike Share Equity Programs: Best Practices And Lessons Learned, Nathan Mcneil, John Macarthur, Adriel Thornton

TREC Webinar Series

Connecting with cities and bike share operators from across the United States, Portland State University conducted a nationwide scan on what programs and initiatives were running to address equity in bike share. The report “National Scan of Bike Share Equity Programs” documents responses from over 70 bike share systems. This resource will help cities and operators navigate the range of actions that have been implemented to make bike share systems more equitable, examine successful strategies employed across the U.S., and understand how those successes (and challenges) are being measured and articulated. In doing so, we hope the report helps bike …
