TREC Webinar Series

With findings from a mixed methods research study, this interdisciplinary webinar will present results from a historical public document analysis, a GIS spatial analyses, client surveys and interviews, and interviews with professionals and service providers. In 2019, the delivery of homeless sheltering services in Salt Lake County transitioned from a centralized emergency shelter to a scattered site model with multiple resource center locations, operated by multiple service providers. To understand the degree to which “proximity” to public transportation and other needed services was achieved, this study examined: how the decentralization of homeless services influenced transportation demand and mobility patterns for …


Fortunate People In A Fortunate Land: Dwelling And Residential Alienation In Santa Monica's Rent-Controlled Housing, Lauren E.M. Everett Apr 2022

Fortunate People In A Fortunate Land: Dwelling And Residential Alienation In Santa Monica's Rent-Controlled Housing, Lauren E.M. Everett

Dissertations and Theses

The importance of safe and stable housing for individual and community wellbeing is widely acknowledged. However, for the one third of Americans who rent their homes, housing-related stress and precarity (residential alienation) may undermine stability and a sense of home. Rent control is perhaps the most well-known tenant protection policy in the United States, but it remains highly controversial and its efficacy has been debated for decades. This research is the first academic inquiry to examine the policy through the experience of residents of rent-controlled housing. In academic discourse dominated by quantitative inquiry from the discipline of economics, this study …


Stakeholder Participation And Influence At State Public Utility Commissions, Genevieve Theresa Kruse Apr 2022

Stakeholder Participation And Influence At State Public Utility Commissions, Genevieve Theresa Kruse

Dissertations and Theses

Despite the international consensus that climate change is a problem, few substantive policies are being pushed forward at the national level to meet international greenhouse gas reduction commitments under the Paris Agreement. The most significant climate change policies are emerging at state public utility commissions (PUCs). While PUCs were traditionally structured to regulate utilities, state PUCs are now finding themselves at the hub for renewable energy, clean energy, and distributed energy policies. Despite the increase in renewable and clean energy policies at state PUCs, there is a noticeably small environmental and clean energy stakeholder presence at those PUC proceedings. A …

Newberg Car Camping Initiative, Katie Carroll, Ryan Haight, Mary Hendricks, Scott Sharba, Anthony Tortorici, Paul Vickers

Master of Urban and Regional Planning Workshop Projects

The Newberg housing market is experiencing the effects of a rapidly growing population on a relatively static housing stock. As competition for a limited supply of housing increases, low- and moderate-income households face the choice of absorbing rising housing costs or being priced out of their homes. This pressure has shown to result in increased rates of housing instability and houselessness in comparable communities across the state. Concerns around housing affordability prompted the Newberg City Council to adopt a 5-Year Housing Work Program in 2020. The 5-Year Housing Work Program consists of 49 housing-related directives intended to address a variety …

Webinar: Exploring Data Fusion Techniques To Derive Bicycle Volumes On A Network, Sirisha Kothuri, Joe Broach, Kate Hyun Mar 2022

Webinar: Exploring Data Fusion Techniques To Derive Bicycle Volumes On A Network, Sirisha Kothuri, Joe Broach, Kate Hyun

TREC Webinar Series

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 …


Global Climate Governance: Rising Trend Of Translateral Cooperation, Nataliya Stranadko Mar 2022

Global Climate Governance: Rising Trend Of Translateral Cooperation, Nataliya Stranadko

Public Affairs and Policy Faculty Publications and Presentations

The transformation from the Kyoto Protocol to the Paris Agreement has been analyzed by international relations scholars, international law, and transnational governance theory. The international relations literature looks at the climate regime from a perspective of power distribution, state interests, institutions, and multilateral negotiations. International law theory focuses on legal analysis and design of international climate agreements. The transnational governance literature examines the participation of transnational actors at different levels of governance. However, each of these theories overlooks a bilateral trend of cooperation in a multilateral setting that arises as part of the construction or reconstruction of the international regime. …

TREC Final Reports

This research developed a method for evaluating and integrating emerging sources (Strava, StreetLight, and Bikeshare) of bicycle activity data with conventional demand data (permanent counts, short-duration counts) using traditional (Poisson) and advanced machine learning techniques. First, a literature review was conducted, along with cataloging and evaluating available third-party data sources and existing applications. Next, six sites (Boulder, Charlotte, Dallas, Portland, Bend, and Eugene) that represented a variety of contexts (urban, suburban) and geographical diversity were selected. Of these, Boulder, Charlotte and Dallas constituted the basic sites, where one year of data (i.e., 2019) was used for modeling. Portland, Bend, and …


Immigration Federalism In The United States: Constructing A Contemporary Institutional Framework Centered On Local Communities Through A Case Study Approach, Sara Kuehlhorn Friedman Feb 2022

Immigration Federalism In The United States: Constructing A Contemporary Institutional Framework Centered On Local Communities Through A Case Study Approach, Sara Kuehlhorn Friedman

Dissertations and Theses

This research study presents a new model of immigration federalism which integrates existing theories into a framework that emphasizes agency at the local level. Unlike dominant models of federalism that observe the cascading effect of higher-level policy on lower levels of government, this research focuses on empirical evidence at the local level to understand its relation to policy at higher levels. Immigration federalism is receiving substantial interest in scholarly work and in practice, but it lacks a cohesive and comprehensive theory explaining variation at the community level. There is little reason to expect sweeping changes in immigration policy at the …


Webinar: Is Transit-Oriented Development Affordable For Low And Moderate Income Households?, Reid Ewing, Justyna Kaniewska Feb 2022

Webinar: Is Transit-Oriented Development Affordable For Low And Moderate Income Households?, Reid Ewing, Justyna Kaniewska

TREC Webinar Series

Transportation and land use planning, as a field, is shifting away from segregated uses connected by highways and streets to more compact, mixed-use developments connected by high-quality transit. This new paradigm has brought special attention to transit-oriented developments (TOD), which are sometimes touted as being among the most affordable, efficient places to live. But how affordable are they, and who has the power to effect change? This study examines housing costs for households living in TODs.

This study, completed in early February 2022, included focus groups and interviews with 18 government employees and service providers, interviews with 19 people experiencing unsheltered homelessness, a review of research literature and news articles on the topic, and previous surveys and research from Portland State University to better understand gaps and opportunities in providing hygiene, storage and waste management to people living unsheltered.


Reckoning With Induced Vehicle Travel, Jamey Volker Feb 2022

Reckoning With Induced Vehicle Travel, Jamey Volker

PSU Transportation Seminars

Empirical research shows that expanding roadway capacity induces more driving - the so-called "induced travel" phenomenon. However, environmental impact assessments and cost-benefit analyses of roadway capacity expansion projects have historically ignored, underestimated, or misestimated this induced travel effect. As a result, they frequently overestimate the projects' potential to relieve congestion and reduce air pollution. That spurred our team at the National Center for Sustainable Transportation (UC Davis) to develop an online tool to facilitate estimation of induced vehicle travel from capacity expansion projects. This presentation will explain the induced travel phenomenon, introduce our induced travel calculator and its offshoots, …


Is Transit-Oriented Development Affordable For Low And Moderate Income Households?, Reid Ewing, Sadegh Sabouri, Justyna Kaniewska, Hassan Ameli, Wookjae Yang, Fatemeh Kiani, Junsik Kim, Douty Chibamba Feb 2022

Is Transit-Oriented Development Affordable For Low And Moderate Income Households?, Reid Ewing, Sadegh Sabouri, Justyna Kaniewska, Hassan Ameli, Wookjae Yang, Fatemeh Kiani, Junsik Kim, Douty Chibamba

TREC Final Reports

The transportation and land use planning paradigm is shifting away from segregated uses connected by highways and roads to more compact, mixed-use developments connected by high-quality transit. This new paradigm has brought transit-oriented development (TOD) to the fore, and researchers continue to highlight advantages of this style of well-integrated land use and transportation planning. When it comes to affordability, what counts isn’t housing costs alone but the combination of housing plus transportation costs (H+T). If TODs do, in fact, command higher rents due to increased transit accessibility, this creates an issue of social equity, especially if higher housing costs are …


Understanding The Impact Of Decentralizing Homeless Services On Transportation And Mobility In Salt Lake County, Sarah L. Canham, Jeff Rose, Ivis Garcia Zambrana, Shannon O. Jones Feb 2022

Understanding The Impact Of Decentralizing Homeless Services On Transportation And Mobility In Salt Lake County, Sarah L. Canham, Jeff Rose, Ivis Garcia Zambrana, Shannon O. Jones

TREC Final Reports

In 2019, the delivery of homeless sheltering services in Salt Lake County transitioned from a centralized emergency shelter—The Road Home Salt Lake Community Shelter and Resource Center (TRHSLC)—operated by The Road Home to a decentralized, scattered site model with multiple “Homeless Resource Center” (HRC) locations operated by multiple service providers. To understand to what degree and to which “proximity” to public transportation and other needed services was achieved, this study examined: 1) how the decentralization of homeless services influenced transportation demand and mobility patterns for persons experiencing homelessness (PEH); and 2) how transportation and mobility changes affected access to services …

Leat, Mansi Patel, Michael Mitchell, Santhosh Medeti, Craig Keaton, Jobaidul Boni, Jhanvi Manishkum, Alireza Fallahi, Sheida Khademi

TREC Final Reports

Roughly 2,000 inmates return to communities each day in the U.S. Unsuccessful reentry jeopardizes community safety, promotes re-incarceration, and increases costs to taxpayers to support the criminal justice apparatus. Research indicates that strong networks of support reduce recidivism, but most communities remain ill-equipped to successfully support former offenders. Our community partner, Unlocking DOORS in Dallas, TX, is a reentry brokerage firm that coordinates services including housing, mental and physical health services, job retraining, transportation, and parole or probation obligations. This, like most reentry service providers, assists former offenders navigating a patchwork of logistical hurdles including individual offender obligations, scarce offender …

Mobility disparities among older adults affect their ability to travel and access services. This project seeks to understand challenges, barriers, and gaps that older adults experience and to develop forms of assistance or educational strategies to fill the varying mobility gaps and meet the mobility needs. This study characterizes older adults’ use of existing and potential transportation options, including conventional transit, paratransit, and ride-hailing systems, based on surveys and interviews collected from community-dwelling older adults in Dallas, Texas. Through the interview during the pandemic, the research team found that perceptual and knowledge barriers appear to be reduced among older adults …


Psu Student Research From The Trb 2022 Annual Meeting: Drone Facility Location Considering Coverage Reliability: Application To Emergency Medical Scenarios, Darshan Chauhan Jan 2022

Psu Student Research From The Trb 2022 Annual Meeting: Drone Facility Location Considering Coverage Reliability: Application To Emergency Medical Scenarios, Darshan Chauhan

PSU Transportation Seminars

Public service agencies like hospitals, fire, rescue, and police departments are required to maintain a high level of service. These service standards often come as reliability constraints. For example, fire-related incidents require a 90% response rate in 4 minutes. We consider a case study of tackling out-of-hospital cardiac events using AED-enabled drones in Portland, OR. Environmental factors, majorly wind speed and direction, significantly impact drone performance. We formulate the drone location problem as a robust multi-period maximum coverage facility location problem. We model the coverage reliability constraint as a chance constraint on failure probabilities. For our context, multiple periods translate …

Psu Student Research From The Trb 2022 Annual Meeting: Effect Of Covid-19 On Property Value Premium Of Light Rail Transit, Sangwan Lee

PSU Transportation Seminars

The COVID-19 pandemic has impacted health and transformed many aspects of our lives, such as travel behavior and residential location preference. For instance, since the outbreak, there was a sharp decline in the ridership of public transportation. Moreover, since the pandemic, a shifting preference toward suburban and exurban areas from denser urban areas like Central Business Districts has been reported. Accordingly, a question arises whether the plummeted transit ridership, alongside the anecdotal and empirical evidence that some households prefer to disperse away from the cities, could combine to transform the long-standing housing price mechanism related to transit proximity. Thus, we …


Heat, Wildfire And Energy Demand: An Examination Of Residential Buildings And Community Equity, Chrissi Argyro Antonopoulos Jan 2022

Heat, Wildfire And Energy Demand: An Examination Of Residential Buildings And Community Equity, Chrissi Argyro Antonopoulos

Dissertations and Theses

Extreme heat and wildfire events are becoming more prolific and exacerbated by climate change, carrying significant implications for environmental and social systems. Residential buildings play a central role in protecting people from heat and pollutant exposure during extreme weather events, but the level of protection varies dramatically depending on building energy efficiency and technology availability. Low-income and communities of color have higher energy burdens compared to affluent populations, and underserved communities often do not have financial resources for, or access to, advanced building technologies. This dissertation explores the impacts of extreme heat and wildfire on residential buildings, focused specifically on …

Data From: Statistical Inference For Multimodal Travel Time Reliability, Avinash Unnikrishnan, Miguel Figliozzi, Subhash C. Kochar

TREC Datasets and Databases

Travel time reliability is a key metric of interest to practitioners and researchers because it affects travel choice and the economic competitiveness of urban areas. This research focuses on three travel time reliability metrics – buffer index, modified buffer index, and the relative width of travel time distributions. The key novel contributions of this research include using the multivariate delta method to prove that the sampling distributions of the three travel time reliability metrics are asymptotically normal. The asymptotic standard error for the three reliability metrics is derived. The asymptotic normality and the standard error result are used to arrive …
