Pursuing Vision Zero In Seattle – Results Of A Systemic Safety Analysis, Rebecca Sanders

PSU Transportation Seminars

Many cities are considering pursuing Vision Zero to eliminate traffic deaths, but may not know how to move beyond addressing past crash locations toward preventing future crashes. Systemic analysis, which looks at crash patterns to determine common characteristics associated with various types of crashes, shows promise in helping cities to identify problematic locations and treatments in the hopes of preventing future crashes.

This presentation will share results from part of Seattle’s Vision Zero effort – a multi-phased analysis of pedestrian and bicycle crash data aiming to help the City understand both where crashes have occurred and where they are most …

Stranding Mortality Patterns In California Sea Lions And Steller Sea Lions In Oregon And Southern Washington, 2006 To 2014, Kessina Lee

Dissertations and Theses

As changing ocean conditions lead to declining fish stocks and movement of forage fish, sea lions on the Oregon coast are subject to the pressures of declining prey availability and increasing conflicts with commercial and recreational fisheries. An analysis of strandings of California sea lions, Zalophus californianus, and Steller sea lions, Eumetopias jubatus, from 2006 to 2014, included cause of death, changing ocean conditions, and anthropogenic activity. Causes of death included disease, injury, and human interaction, such as gunshot wounds, fisheries net entanglements and boat strikes.

Oregon and Washington strandings of California sea lions are primarily adult and …

Where Is Portland Made? The Complex Relationship Between Social Media And Place In The Artisan Economy Of Portland, Oregon (Usa), Stephen Marotta, Austin Cummings, Charles H. Heying

Urban Studies and Planning Faculty Publications and Presentations

Portland, Oregon (USA) has become known for an artisanal or ‘maker’ economy that relies on a resurgence of place specificity (Heying), primarily expressed and exported to a global audience in the notion of ‘Portland Made’ (Roy). Portland Made reveals a tension immanent in the notion of ‘place’: place is both here and not here, both real and imaginary. What emerges is a complicated picture of how place conceptually captures various intersections of materiality and mythology, aesthetics and economics. On the one hand, Portland Made represents the collective brand-identity used by Portland’s makers to signify a products’ material existence as handcrafted, …

Agent-Based Model Simulating Pedestrian Behavioral Response To Environmental Structural Changes, Amy Lobben, Christopher Bone

TREC Final Reports

Our research focused on understanding the travel behavior of individuals in complex urban environments. Specifically, we investigated how land use patterns and infrastructure influence how individuals across a broad range of travel abilities navigate through urban landscapes. Our overall project goal was to develop a transportation planning tool that allows users to simulate pedestrian travel behavior. The tool was built on a computation model that was developed through rigorous measures and observations of pedestrian travel behavior. Our definition of pedestrian includes a broad perspective as one of our aspirations through this project was to expand the definition of what constitutes …

Wildfire Risk As A Socioecological Pathology, A. Paige Fischer, Thomas A. Spies, Toddi A. Steelman, Cassandra Moseley, Bart R. Johnson, John D. Bailey, Alan A. Ager, Patrick Bourgeron, Susan Charnley, Brandon M. Collins, Jeffrey D. Kline, Jessica E. Leahy, Jeremy S. Littell, James D. A. Millington, Max Nielsen-Pincus, Christine S. Olsen, Travis B. Paveglio, Christopher I. Roos, Michelle M. Steen-Adams, Forrest R. Stevens, Jelena Vukomanovic, Eric M. White, David Bowman

Environmental Science and Management Faculty Publications and Presentations

Wildfire risk in temperate forests has become a nearly intractable problem that can be characterized as a socioecological “pathology”: that is, a set of complex and problematic interactions among social and ecological systems across multiple spatial and temporal scales. Assessments of wildfire risk could benefit from recognizing and accounting for these interactions in terms of socioecological systems, also known as coupled natural and human systems (CNHS). We characterize the primary social and ecological dimensions of the wildfire risk pathology, paying particular attention to the governance system around wildfire risk, and suggest strategies to mitigate the pathology through innovative planning approaches, …

Can Significant Trends Be Detected In Surface Air Temperature And Precipitation Over South America In Recent Decades?, Daniel De Barros Soares, Huikyo Lee, Paul C. Loikith, Armineh Barkhordarian, Carlos R. Mechoso

Geography Faculty Publications and Presentations

Trends in near-surface air temperature and precipitation over South America are examined for the periods 1975–2004 and 1955–2004, respectively, using multiple observational and climate model data sets. The results for observed near-surface air temperature show an overall warming trend over much of the continent, with the largest magnitudes over central Brazil. These observed trends are found to be statistically significant using pre-industrial control simulations from the fifth phase of the Coupled Model Intercomparison Project (CMIP5) as the baseline to estimate natural climate variability. The observed trends are compared with those obtained in natural-only CMIP5 simulations, in which only natural forcings …

Connecting People To Places: Spatiotemporal Analysis Of Transit Supply Using Travel-Time Cubes, Steven Farber

TREC Final Reports

Despite its importance, temporal measures of accessibility are rarely used in transit research or practice. This is primarily due to the inherent difficulty and complexity in computing time-based accessibility metrics. Estimating origin-to-destination travel times that include the “last mile” of travel between the transit network and actual start and endpoints of the trip is technically difficult. Not only do such estimations require multimodal network structures, they also require detailed knowledge of transit schedules and sophisticated algorithms for calculating shortest paths using such inputs. Recently, new standards for sharing transit schedules and geographic data, namely the General Transit Feed Specification (GTFS) …

Factors Driving The Concentration Of Ephemeral Flow, Gretchen Anne Guyer

Dissertations and Theses

In spite of decades of related research, stream channel initiation is still not well understood. Current theories of channel initiation are grounded in research conducted by Montgomery and Dietrich, largely in the transport limited, temperate, humid climate of the Pacific Northwest, USA. This field data driven work concluded that the drainage area required for channel initiation is directly correlated to the slope of the contributing area. However, there are a host of related variables that have yet to be examined in the field. This study revisits the slope-area relationship focusing on ephemeral overland flow in headwaters of both the Pacific …

The "Adam Cube" : Categorizing Portland, Oregon's Urbanization Using Gis And Spatial Statistics, Jeremy Grotbo

Dissertations and Theses

Transportation availability and land use intensity demonstrate a strong relationship, with intense development concentrated near significant transportation investment. Transportation networks evolved in response to emergent transportation technologies and changing urban land uses. The irregular distribution of transportation systems reinforced patterns of land use development, shaping urban form. Understanding the relationships between transportation and the intensity of land uses allows urban geographers and city planners to explain the urbanization processes, as well as to identify areas historically susceptible to future development. The goal of this research is to develop a quantitative framework for the analysis of the development of urban form …

On The Variability Of Pacific Ocean Tides At Seasonal To Decadal Time Scales: Observed Vs Modelled, Adam Thomas Devlin

Dissertations and Theses

Ocean tides worldwide have exhibited secular changes in the past century, simultaneous with a global secular rise in mean sea level (MSL). The combination of these two factors contributes to higher water levels, and may increase threats to coastal regions and populations over the next century. Equally as important as these long-term changes are the short-term fluctuations in sea levels and tidal properties. These fluctuations may interact to yield locally extreme water level events, especially when combined with storm surge. This study, presented in three parts, examines the relationships between tidal anomalies and MSL anomalies on yearly and monthly timescales, …

Locating Truck Data Collection Sites In Oregon Using Representation Optimal Sampling, Kenneth Dueker, William A. Rabiega, Bruce Rex

Center for Urban Studies Publications and Reports

The Oregon Department of Transportation collects data on the performance of the highway system by sampling traffic volume, vehicle classification, truck weights, pavement conditions, etc. The selection of efficient and accurate locations for collecting data is important. This report addresses the larger sampling problem by focusing on locations for collecting truck weight data. Sites selected for weight-in-motion/automatic vehicle identification (WIM/AVI) within the Crescent/HELP project are assessed to determine their locational suitability for truck weight data collection. A method, Representation Optimal Sampling (ROS), to aid in site selection is reported here. Sampling configurations of six and twelve station using ROS are …

Geography Of Gender And The Gender Of Geography In The Roman Imagination, Austin Howard

Student Research Symposium

This paper argues for a profound link between gendered stereotypes and geography in the Graeco-Roman imagination focusing on the early Roman Empire. Hitherto, this link has been mentioned, sometimes assumed, and almost never treated as a venture worthy or deeper study or unifying themes, apart from questions of “proto-racism.” Notwithstanding, the links can be drawn comparing how the peoples living in different parts of the empire are described and how stereotypes of gender also appear in historical and literary texts. By careful examination (including cross-examination) of Strabo, Tacitus, Livy, Julius Caesar, and others, I seek the argue for a strong …

Aquifer Vulnerability Modeling In New Jersey Through The Use Of Modified Drastic Methodology, Clement Uduk, Tanja Hopmans

Student Research Symposium

Due to the global average increase in temperature over the last 50 years, sea levels have been rising and making coastal aquifers more susceptible to saltwater intrusion. The average rate of sea level rise has increased from 2 mm/year to 3.5 mm/year during the twentieth century. The state of New Jersey is not only densely populated but the development along coastlines makes inundation a potential serious threat. New Jersey is diverse in aquifer types, in addition to the types of water bodies surrounding New Jersey, and makes for an interesting case study for groundwater vulnerability. The EPA has a universal …

Then And Now: Vegetative Change Detection On Mount St. Helens 2000-2015, Douglas S. Thalacker, Andrés Holz

Student Research Symposium

The 1980 eruption of Mount St. Helens (MSH) proved a dramatic event with many important socio-economic consequences. In addition, this eruption resulted in an array of ecological consequences with subsequent studies and profound theoretical ramifications. The eruption created a complex gradient in disturbance severity on the northern aspect of MSH3, promoting successional processes from varying starting points and change rates. This study uses a landscape-scale approach to quantify spatio-temporal trends in vegetative responses to the eruption from 2000-2015, relying on Landsat TM and ETM+ imagery focusing on the primary and (i.e. no biological legacies) secondary (i.e. with biological legacies) succession …

Multimodal Transportation Planning Curriculum For Urban Planning Programs, Kristine M. Williams, Tia Claridge, Alexandria Carroll

TREC Final Reports

Integrated multimodal transportation and land use planning is critical to advancing mode choice, public health and safety, and livability objectives. Communities across the U.S. are seeking to redefine their planning process accordingly. In response, university graduate urban planning and engineering programs are beginning to address multimodal planning and sustainable transportation, but most do not yet offer a robust curriculum on these topics. To help address this need, the University of South Florida (USF), Center for Urban Transportation Research (CUTR) developed a curriculum for a course on multimodal transportation planning and its role in advancing livability and related objectives. The course …

Advanced Gis: Smart Transportation, Christopher Bone, Ken Kato, Jacob Bartruff, Marc Schlossberg

TREC Final Reports

As sensors have become cheaper and more common, they have found an increasingly important role in transportation. However, curriculum to prepare students who will be working with these technologies as developers and planners has not developed at the same rate. The goal of this project was to develop a college course focused around sensors and smart transportation to be offered to undergrad and graduate students at the University of Oregon. The class focused on the practical application and the theoretical consequences of these developments. The class was offered in the spring term of 2015 to a group of undergraduate and …

Urban Studies and Planning Faculty Publications and Presentations

The article looks into the critical geographic information science (GIS) in approaching questions both emerging and enduring around the intersection of the spatial and the digital. It offers trading zones for discussion of issues, for building alliances and interrogating tensions, and for a constant dialectical process of critique and renewal. One tension running through critical GIS is the contradictory role it has played in addressing questions of social justice.

Track Time And Monetary Costs Of Transportation As A Comprehensive Performance Measure: Development And Application Of Transportation Cost Index, Liming Wang

PSU Transportation Seminars

As federal and state policies place increasing emphasis on using comprehensive transportation performance measures to guide transportation decision making, there is a gap in such measures of transportation and land use systems. This seminar reports the results from a research project aiming to fill the gap in the type of applications and policy areas covered by existing measures. Modeled after the popular Consumer Price Index, the project refines and develops a transportation cost index (TCI) measure for transportation and land use systems by tracking the time and monetary costs of transportation for households as they travel to satisfy their daily …

Slavery: The Main Ingredient To An Ancient Greek Polis' Military Dominance, Steven T. Tran

Young Historians Conference

Spartan and Athens' victories against the Persians and their eventual military dominance cannot be attributed to military strategy or government alone. The social acceptance of slavery provided the foundation for Greek poleis' social and economic spheres, leading to the development of slave deployment during the Persian Wars and Peloponnesian War. An in-depth analysis of Classical Greece slavery shows that its prevalence is much greater than what previous historians have thought, and more notably, that it was one of the most massive slave usage in history, allowing for the development of a dominating western world.

Crisis In Education -- The Effect Of The Cold War On The American Education System, Spencer C.J. Gregg

Young Historians Conference

The Cold War era had a dramatic impact on the American educational system. Striving to demonstrate superiority over Soviet counterparts, new curriculum were developed to prepare the American youth intellectually, emotionally, and technologically to position the U.S. as a world power. With the American public polarized whether schools were a venue for the dissemination of national ideologies or institutions for the development of critical thinking; world events including nuclear warfare, space exploration, and military preparedness served as catalysts for the development of future citizens that would effectively contribute to the intellectual and technological growth of the nation.

Minimum Wage Increases And Oregon’S Long-Term Care Sector, Mike Paruszkiewicz, Peter Hulseman, Emma Willingham

Northwest Economic Research Center Publications and Reports

Analysis of direct and "ripple" effects of Oregon's recent minimum wage increase in the long-term care industry.

Minimum wage proposals have dominated recent policy debate in Oregon, culminating in the February 2016 legislative session that included the passage of Senate Bill 1532, a three-tiered minimum wage increase to be phased in between 2016 and 2022. Barring changes in other states, the law will give Oregon the highest minimum wage in the country. While the immediate impacts of the law on workers earning near the minimum are substantial and relatively clear-cut, businesses face less certain outcomes as the delicate balance between …

How Landscape Ecology Informs Global Land-Change Science And Policy, Audrey L. Mayer, Brian Buma, Amélie Davis, Sara A. Gagné, E. Louise Loudermilk, Robert M. Scheller, Fiona K.A. Schmiegelow, Fiona Majorin, Yolanda F. Wiersma, Janet Franklin

Environmental Science and Management Faculty Publications and Presentations

Landscape ecology is a discipline that explicitly considers the influence of time and space on the environmental patterns we observe and the processes that create them. Although many of the topics studied in landscape ecology have public policy implications, three are of particular concern: climate change; land use–land cover change (LULCC); and a particular type of LULCC, urbanization. These processes are interrelated, because LULCC is driven by both human activities (e.g., agricultural expansion and urban sprawl) and climate change (e.g., desertification). Climate change, in turn, will affect the way humans use landscapes. Interactions among these drivers of ecosystem change can …
