The Hidden Killer: Towards Regulating Railyard Diesel Particulate Matter Emissions In Oregon, Kevin Downing, Robert Mccullough, Eric Shierman Aug 2019

The Hidden Killer: Towards Regulating Railyard Diesel Particulate Matter Emissions In Oregon, Kevin Downing, Robert Mccullough, Eric Shierman

Hatfield Graduate Journal of Public Affairs

Diesel engines are the predominant choice when moving freight, particularly for the railroad industry. Compared to gasoline engines, diesel emits relatively few of the toxic compounds generally associated with internal combustion. However, diesel engines produce a disproportionate quantity of particulate aerosols. Airborne pollutants from locomotives and freight transferring equipment in railyards significantly impact the air quality of surrounding neighborhoods. We summarize the health impacts of diesel particulates emitted from railyards in Oregon. Using the most conservative range of the EPA's assessment, we calculate a Pigouvian Tax for the railroad companies to pay, totaling $624.24 per μg/m3 for each person in …

Has Portland Been Demolishing Its Green Spaces? A Remote Sensing Analysis Of Portland's Urban Vegetation, Robby Gottesman, Eric Shierman Aug 2019

Has Portland Been Demolishing Its Green Spaces? A Remote Sensing Analysis Of Portland's Urban Vegetation, Robby Gottesman, Eric Shierman

Hatfield Graduate Journal of Public Affairs

The magnitude of the Urban Heat Island effect (UHI) in Portland, Oregon is determined from June 1984 to September 2017, and used as a proxy for urban development. This analysis demonstrates that the magnitude of Portland's UHI has remained largely unchanged over this period, implying no significant decline in its urban vegetation. This is supported by analysis of the Enhanced Vegetation Index (EVI) of the Portland Metro area, which has also remained largely unchanged over the period studied. An estimate of the total area of vegetation detectable via satellite in the Portland Metro is also determined and found to have …


Re-Imagining Regulatory Approaches For Methane Emissions, Jongeun You Aug 2019

Re-Imagining Regulatory Approaches For Methane Emissions, Jongeun You

Hatfield Graduate Journal of Public Affairs

Recently, the U.S. Environmental Protection Agency (EPA) took a step-back in regulating the methane released during natural gas extraction. In June 2016, the EPA issued the first federal regulations on methane, estimating methane emissions would decrease by a total of 510,000 short tons in 2025, with a potential net benefit of $160 million. Yet, in October 2018, the EPA released a new proposal that weakened the 2016 methane rules, estimating methane emissions would increase by a total of 380,000 short tons in 2025, with a potential saving of $484 million. This paper explores the EPA’s drastic change between 2016 and …


A Network Approach To Complex Problems: Understanding Collaborative Governance In Watershed Management, Allison Daniel Aug 2019

A Network Approach To Complex Problems: Understanding Collaborative Governance In Watershed Management, Allison Daniel

Hatfield Graduate Journal of Public Affairs

The complexity of current environmental problems poses a challenge to the field of public management. With multiple stressors acting on the earth’s natural systems, the likelihood that complex environmental problems will persist is undeniable. Traditional approaches to such problems follow a top-down method, often useful for problem management within public policy; however, it proves too rigid when considering the complexity of environmental policy. Recent literature points to the use of collaboration and coordination in addressing complex problems, whereby stakeholders accumulate knowledge and resources across a variety of fields. One such method is network governance, identified as a problem-solving approach capable …


No Easy Answer: Representative Bureaucracy And Police Use Of Force, Jacob Herrera Aug 2019

No Easy Answer: Representative Bureaucracy And Police Use Of Force, Jacob Herrera

Hatfield Graduate Journal of Public Affairs

The theory of Representative Bureaucracy is a well-studied concept in Public Administration, positing that more representative government agencies will lead to greater equity for underserved groups. This paper is review of empirical applications of the theory to the use of force by police and it will show that the work does not support the idea that more representative police departments correlate with lower rates of use of force against minority groups. Implications for future studies are addressed at the end of the article.


Moving Beyond ‘Therapy’ And ‘Enhancement’ In The Ethics Of Gene Editing, Bryan Cwik Aug 2019

Moving Beyond ‘Therapy’ And ‘Enhancement’ In The Ethics Of Gene Editing, Bryan Cwik

Philosophy Faculty Publications and Presentations

Since the advent of recombinant DNA technology, expectations (and trepidations) about the potential for altering genes and controlling our biology at the fundamental level have been sky high. These expectations have gone largely unfulfilled. But though the dream (or nightmare) of being able to control our biology is still far off, gene editing research has made enormous strides toward potential clinical use. This paper argues that when it comes to determining permissible uses of gene editing in one important medical context—germline intervention in reproductive medicine—issues about enhancement and eugenics are, for the foreseeable future, a red herring. Current translational goals …

Understanding Factors Affecting Arterial Reliability Performance Metrics, Jason C. Anderson, Rohan Sirupa, Sirisha Kothuri, Avinash Unnikrishnan

TREC Final Reports

In recent years, the importance of travel time reliability has become equally important as average travel time. However, the majority focus of travel time research is average travel time or travel time reliability on freeways. In addition, the identification of specific factors (i.e., peak hours, nighttime hours, etc.) and their effects on average travel time and travel time variability are often unknown. The current study addresses these two issues through a travel time-based study on urban arterials. Using travel times collected via Bluetooth data, a series of analyses are conducted to understand factors affecting reliability metrics on urban arterials. Analyses …

TREC Final Reports

This project builds an open-source, socio-transportation analytic (STAT) toolbox for public transit system planning in an effort to integrate social media and general transit feed specification (GTFS) data for transit agencies in evaluating and enhancing the performance of public transit systems. This toolbox is novel and essential to transit agencies in two aspects. First, it enables the integration, analysis and visualization of two major, new open transportation data, social media and GTFS data, to support transit decision-making. Second, it allows transit agencies to evaluate service network efficiency and access equity of transit systems in a cohesive manner, and identify areas …


Bicycle Planning Gis Tool, Joseph Broach Jul 2019

Bicycle Planning Gis Tool, Joseph Broach

TREC Final Reports

Although currently only about one percent of US trips are done by bicycle, there is significant geographic variation. Differences across communities, along with much higher cycling rates observed in other places around the world, indicates large potential bicycling demand for daily travel in the US. In response, many communities are developing and implementing bicycle master plans that include a range of bikeway infrastructure aimed at making riding more appealing, including separated paths, protected (or separated) bike lanes, striped bike lanes, bicycle boulevards, sharrows, route signage, and intersection crossing aids. Given limited resources, planners and engineers need tools to estimate the …


Characterizing The Trip Generation Profiles Of Multifamily Housing, Kelly Clifton, Kristina M. Currans Jul 2019

Characterizing The Trip Generation Profiles Of Multifamily Housing, Kelly Clifton, Kristina M. Currans

TREC Final Reports

Cities are increasingly wanting to assess the impacts new development has on all modes in the transportation system. Many communities are requiring site-level transportation impact analysis to examine travel outcomes. The historical focus on developing data and methods exclusively for the automobile, such as the Institute of Transportation Engineers (ITE) Trip Generation Handbook, has left planners with little guidance for these new challenges. This study aims to examine the limitations in the dominant approaches to understand how they may misguide the planning process for multifamily housing development. Specifically, we aim to examine the vehicle and person trip generation rates associated …

TREC Final Reports

As bike share systems around the United States have grown in number and size in recent years, there has been an increasing effort to ensure that those systems are accessible to all residents, particularly those who have the fewest resources or have been underserved in the past. The mobility landscape in 2019 is rapidly changing, with scooter and e-bike systems along with ride-hailing and ride-sharing companies contributing to a new and uncharted urban transportation scene. Meanwhile, bike share is still relatively new and changing quickly. In order to compete and excel in this changing landscape, particularly with regard to providing …


Spatial Analysis Of Burglary And Robbery Crime Concentration Near Mass-Transit In Portland, Bryce Edward Barthuly Jun 2019

Spatial Analysis Of Burglary And Robbery Crime Concentration Near Mass-Transit In Portland, Bryce Edward Barthuly

Dissertations and Theses

The relationship between mass-transit and the concentration of burglary and robbery crimes is inconsistent within the available literature in environmental criminology. A number of studies have provided evidence of crime concentration at and near mass transit locations where paths intersect, referred to as a node. These empirical studies bring in environmental criminology theory with the idea that crime is clustered, and the pattern of the concentrations is substantially influenced by how and why people travel and move in a city. It is suggested that public transit allows for a large proportion of the population to move around the community along …

Evaluating Project Assessment Techniques For High-Profile Transportation Projects Development And Delivery: Case Of State Departments Of Transportation (Dots) In The United States, Rafaa Ibrahim Khalifa

Dissertations and Theses

Time delays and cost overruns in construction projects are generally due to factors such as inappropriate planning, design errors, unexpected site conditions, inadvisable tools selection, change scope, weather conditions, lack of resources, and other project changes. Time delays and cost overruns are of concern to most project managers, owners, and governments. These elements of time and cost are two of the critical defects that impact the construction project delivery. These defects can lead to project failures and to various negative issues like increasing in disagreements among the project team, the contractor, suppliers, and the owner.

State Departments of Transportation (DOTs) …


Making Imaginaries: Identity, Value, And Place In The Maker Movement In Detroit And Portland, Stephen Joseph Marotta Jun 2019

Making Imaginaries: Identity, Value, And Place In The Maker Movement In Detroit And Portland, Stephen Joseph Marotta

Dissertations and Theses

This dissertation explores the maker economy and culture in Detroit, MI and Portland, OR and queries the "Made in Place" branding strategy that relies so heavily on a shared imagination of cities, identities, and values. Bridging the gap between urban economic development, political economy, and affect theory, this dissertation is centrally concerned with how imagination works as a commons and how such "imaginaries" shape each city's milieu of small, entrepreneurial, artisanal producers ("makers"). The constituent elements of "Made in" branding "made" and "place" suggest common understandings of each; this sense of coherence is critical for how value is added to …

Small Towns With Big City Problems: Mobility Challenges And Solutions In Our Natural Areas, Danya Rumore, Philip Stoker, Zacharia Levine, Lindsey Romaniello

TREC Project Briefs

Western North America boasts an abundance of scenic mountains, ski areas, stunning desert landscapes and national parks. Living near these natural amenities are small communities, many of which are becoming increasingly popular places to live and visit. The influx of visitors creates unique transportation and mobility challenges for these small towns and cities, such as seasonal spikes in severe roadway congestion and a desire for e-bike share programs in communities of less than 1,000 people. These challenges often in turn affect community character and wellbeing.

Given their proximity to these impacted communities, NITC researchers Danya Rumore of the University of …

Aligning Endangered Species Management With Fire-Dependent Ecosystem Restoration: Manager Perspectives On Red-Cockaded Woodpecker And Longleaf Pine Management Actions, Shelby A. Weiss, Eric L. Toman, R. Gregory Corace Iii Jun 2019

Aligning Endangered Species Management With Fire-Dependent Ecosystem Restoration: Manager Perspectives On Red-Cockaded Woodpecker And Longleaf Pine Management Actions, Shelby A. Weiss, Eric L. Toman, R. Gregory Corace Iii

Geography Faculty Publications and Presentations

Background: Endangered species management has been criticized as emphasizing a single-species approach to conservation and, in some cases, diverting resources from broad-based, land management objectives important for overall biodiversity maintenance. Herein we examine perceptions on management for an endangered species whose habitat requirements largely depend on frequent fire, the red-cockaded woodpecker (Leuconotopicus borealis Vieillot). In doing so, we consider the alignment between species-specific population recovery actions and broader ecosystem restoration goals. Through semi-structured interviews with natural resource professionals (n = 32) in the Southeast Coastal Plain of the United States, we examined manager perspectives on the evolution of recovery …

Living Streets: A Pathway Toward Inclusive, Equitable, And Accessible Pedestrian Streets, Eavan Moore, Kevin Tracy, Jason Nolin, Zoie Wesenberg, Oscar Saucedo-Andrade, Kate Wihtol Jun 2019

Living Streets: A Pathway Toward Inclusive, Equitable, And Accessible Pedestrian Streets, Eavan Moore, Kevin Tracy, Jason Nolin, Zoie Wesenberg, Oscar Saucedo-Andrade, Kate Wihtol

Master of Urban and Regional Planning Workshop Projects

Since 2009, the Portland Bureau of Transportation (PBOT) has aimed to prioritize pedestrians above all other transportation modes. By putting pedestrians first, cities can improve outcomes for communities and transform streets into welcoming public spaces. Pedestrian streets help achieve this goal by reallocating space that was once dedicated to the movement and storage of cars to spaces for people to interact, socialize, and recreate. By developing a typology and an evaluation framework for pedestrian streets, this document attempts to answer the question, what could pedestrian streets look like in Portland’s Central City?

Life-Space Mobility: How Transportation And Policy Can Support Aging In Place For Older Adults, Ivis Garcia Zambrana, Alan Kenneth Delatorre Jun 2019

Life-Space Mobility: How Transportation And Policy Can Support Aging In Place For Older Adults, Ivis Garcia Zambrana, Alan Kenneth Delatorre

TREC Project Briefs

Research on older adults frequently explores the notion of "aging in place"—providing older adults the opportunity to continue to live in their own homes and communities. However one’s ability to stay or leave, particularly in old age, often depends on the built environment. An accessible neighborhood that prioritizes mobility affords the ability to meet basic needs like goods, services, and social activities.

This life-space mobility is rarely applied in the field of urban planning and architecture. A NITC project led by Ivis Garcia Zambrana of the University of Utah and Alan DeLaTorre of Portland State University sought to operationalize this …
