An Assessment Of Bicycle Detection Confirmation And Countdown Devices, Christopher Monsere, Sirisha Kothuri, David S. Hurwitz

PSU Transportation Seminars

For a person on a bicycle at intersections, trail crossings, or midblock locations that are signalized, knowing that they have been detected and how long they must wait to receive a green indication is valuable information. This presentation will summarize the findings from the online survey (1,048 responses), observed behaviors (2,428 persons on bicycle), and an intercept survey ( 234 persons) to understand blue light feedback devices and countdown timers at signalized intersections.

Findings suggest that the design where the blue light was embedded in the sign was more visible to cyclists and observed by higher proportions of cyclists in …

New Mobility For All: Evaluation Of A Transportation Incentive Program For Residents Of Affordable Housing In Portland, Or, Nathan Mcneil, John Macarthur, Huijun Tan

TREC Final Reports

Low-income residents, immigrants, seniors, and people with disabilities - people who are often the most transport disadvantaged and thus stand to gain the most from tools that could reduce transportation costs and time – are often poorly served by new transportation tools and services, whether due to issues of affordability, gaps in technology adoption, unbanked populations, social or knowledge gaps, physical access, or other barriers. The research team worked with the Portland Bureau of Transportation (PBOT) to evaluate the Transportation Wallet for Residents of Affordable Housing Pilot (TWRAH). The program provided a set of transportation incentives for low-income participants including …

Centennial School District Enrollment Forecasts 2021-22 To 2030-31, Portland State University. Population Research Center, Charles Rynerson, Christina Wei

School District Enrollment Forecast Reports

In August 2021 the Portland State University Population Research Center (PRC) prepared high, middle, and low scenarios of district‐wide enrollment forecasts by grade level for the Centennial School District (CSD) for the 10‐year period between 2021‐22 and 2030‐31. Each enrollment forecast scenario is related to population forecasts that incorporate different assumptions about growth within the District, with the primary differences being the contribution of net migration to the District’s population and age distribution. To facilitate the boundary review process, PRC also provided forecasts of CSD students residing within each existing elementary attendance area, consistent with the middle series, to CSD …

Webinar: Data-Driven Mobility Strategies For Multimodal Transportation, Yao-Jan Wu, Abolfazl Karimpour, Xianfeng Terry Yang

TREC Webinar Series

Multimodal transportation systems (e.g., walking, cycling, automobile, public transit, etc.) are effective in increasing people’s travel flexibility, reducing congestion, and improving safety. Therefore, it is critical to understand what factors would affect people’s mode choices. With advanced technology, such as connected and automated vehicles, cities are now facing a transition from traditional urban planning to developing smart cities. To support multimodal transportation management, this study serves as a bridge to connect speed management strategies of conventional corridors to connected vehicle corridors.

The study consists of three main components. In the first component, the impact of speed management strategies along traditional …

Road Work Ahead: Using Deep Neural Networks To Estimate The Impacts Of Work Zones, Abbas Rashidi, Ali Hassandokht Mashhadi

TREC Project Briefs

Roadside construction - be it a detour, a closed lane, or a slow weave past workers and equipment - work zones impact traffic flow and travel times on a system-wide level. The ability to predict exactly what those impacts will be, and plan for them, would be a major help to both transportation agencies and road users. Funded by the National Institute for Transportation and Communities, the latest Small Starts project led by Abbas Rashidi of the University of Utah introduces a robust, deep neural network model for analyzing the automobile traffic impacts of construction zones.

Evaluating Mobility Impacts Of Construction Work Zones On Utah Transportation System Using Machine Learning Techniques, Ali Hassandokht Mashhadi, Abbas Rashidi

TREC Final Reports

Construction work zones are inevitable parts of daily operations at roadway systems. They have a significant impact on traffic conditions and the mobility of roadway systems. The traffic impacts of work zones could significantly vary due to several interacting factors such as work zone factors (work zone location and layout, length of the closure, work zone speed, intensity, and daily active hours); traffic factors (percentage of heavy vehicles, highway speed limit, capacity, mobility, flow, density, congestion, and occupancy); road factors (number of total lanes, number of open lanes, and pavement grade and condition); temporal factors (e.g., year, season, month, weekday, …

Adoption And Use Of E-Grocery Shopping In The Context Of The Covid-19 Pandemic: Implications For Transport Systems And Beyond, Gabriella Abou-Zeid

Dissertations and Theses

In 2020, the COVID-19 pandemic drastically impacted travel for in-person shopping, commute trips, global supply chains, and food business operations. Previously mundane tasks, like shopping for food and household items, became markedly different as new social distancing and mask guidelines were put in place to mitigate the spread of COVID-19. Concurrently, e-commerce sales in the U.S. skyrocketed. E-grocery pickup and delivery services saw unprecedented expansions. The adoption and use of e-grocery services have implications for equity and mobility, although the nature of the relationship of e-grocery to the latter is still unclear. Enhancing our understanding of the drivers of (and …

Exploring How Gentrification-Related Effects Impact The Health Of Older Black Adults, Ann Wachana, Holly Hinson

McNair Symposium

Black adults living in gentrifying neighborhoods experience cultural incongruence with new, often younger, high SES and White residents. In addition, older Black adults are losing deep ties to their neighborhood. This is a major loss to their social network and their sense of belonging within their own neighborhoods. Disruption of long-standing social ties can cause changes in mental health and raises concerns about gentrification’s potentially disruptive impact on cognitive health and the brain aging process. In order to learn more about the experience of older Black adults within a rapidly changing city, focus group discussions from the Sharing History through …

Mopping Up Or Turning Off The Tap? Environmental Injustice And The Ethics Of Plastic Pollution, Katharine A. Owens, Katie Conlon

Urban Studies and Planning Faculty Publications and Presentations

Opinion article

Decades of scientific research confirm that plastic pollution poses a threat to many species, to water resources, and to economies around the world (Laist, 1997; Barnes et al., 2009; Gregory, 2009; Teuten et al., 2009; Chen, 2015; Newman et al., 2015; Rochman, 2015). Experts demonstrate that oceanic plastic pollution is increasing at astounding rates (Eriksen et al., 2014; Geyer et al., 2017). Research indicates harmful levels of toxicity in everyday plastic items (SCP/RAC, 2020). Scientists find this issue so important that they have recommended plastics …

Marine Debris And Human Health: An Exposure Pathway Of Pops?, Katie Conlon

Urban Studies and Planning Faculty Publications and Presentations

Although there are not any direct studies linking persistent organic pollutants (POPs) accumulated on marine debris to human health, there are numerous studies showing human health impacts from repeated and high level POP exposure, as well as studies that show POPs accumulate on plastic debris in the marine environment. With this knowledge, there is a need for greater awareness of the risks of POP exposure for those who handle marine debris regularly, especially in contexts of higher exposure such as those working in marine debris concentrated areas. Amongst the scientific community, understanding of the exposure risk might be high, but …

Spatial Configuration And Time Of Day Impact The Magnitude Of Urban Tree Canopy Cooling, Miguel Alonzo, Matthew Baker, Yuemeng Gao, Vivek Shandas

Urban Studies and Planning Faculty Publications and Presentations

Tree cover is generally associated with cooler air temperatures in urban environments but the roles of canopy configuration, spatial context, and time of day are not well understood. The ability to examine spatiotemporal relationships between trees and urban climate has been hindered by lack of appropriate air temperature data and, perhaps, by overreliance on a single ‘tree canopy’ class, obscuring the mechanisms by which canopy cools. Here, we use >70 000 air temperature measurements collected by car throughout Washington, DC, USA in predawn (pd), afternoon (aft), and evening (eve) campaigns on a hot summer day. We subdivided tree canopy into …

Green Waves, Machine Learning, And Predictive Analytics: Making Streets Better For People On Bikes, Stephen Fickas

TREC Final Reports

This project focuses on giving bicyclists a safer and more efficient path through a city’s signalized intersections. It builds on a prior NITC project that tested an app for a fixed-time corridor. The goal of this project is to lay the groundwork for extending this earlier app to include actuated signals. Two machine-learning algorithms are introduced that have a good track record with time-series forecasting: LSTM and 1D CNN. The algorithms are tested on data captured from a busy bike corridor on the south end of the University of Oregon campus. A specific actuated intersection is identified on this corridor …

Data Files: Green Waves, Machine Learning, And Predictive Analytics: Making Streets Better For People On Bikes, Stephen Fickas

TREC Datasets and Databases

The project builds on a prior app that was designed for Green Light Optimized Speed Advisory (GLOSA). This is more colloquially known as keeping a vehicle in the green wave: you are at a location and moving at a speed that will allow you to (theoretically) have a green light at each intersection you encounter along a corridor. Our long-term goal is to extend the FastTrack app described in the Background section to include actuated signals along a corridor. This project takes a first step by evaluating the effectiveness of machine-learning algorithms to predict the next phase of an actuated …

The Residential Property Value Premium Of The Proximity To Carsharing And Bikesharing Services: Evidence From New York City, Sangwan Lee, Aaron D. Golub

Urban Studies and Planning Faculty Publications and Presentations

While significant existing scholarship has confirmed that accessibility to “macro” transportation systems, such as transit, creates some value for real estate, few studies have examined the capitalized effect of “micro” transportation modes on property values. Even, despite the increased ridership and market shares of carsharing and bikesharing services, empirical evidence on its property value capitalization effects of the emerging transportation services remains far less limited. In this context, this research examines the residential value uplift induced from the proximity to carsharing (Zipcar) and bikesharing (CitiBike) services in New York City by employing Spatial Durbin Models with sales transaction data that …

These challenges are interconnected, reinforcing the need for increased coordination of economic and workforce development efforts. This article outlines the evaluation findings of a novel business-facing initiative called the Genesis Movement, to understand its role in reshaping the workforce experience within small- and medium-sized manufacturing businesses in Chicago, Illinois. Spearheaded in 2014 by the Illinois Manufacturing Excellence Center (IMEC), Genesis starts with the premise that workforce practices are central to business operations, productivity, and competitiveness—and therefore, manufacturing extension services need to promote improvements to job quality in support …

Racialized Space: Historical, Economic, And Social Factors Contributing To The Gentrification Of North & Northeast Portland's Albina Neighborhoods, Red Burkett

University Honors Theses

Portland, Oregon has long held the reputation of being a quirky, artistic, mid-size American city for the ecologically friendly and progressively minded. What is less well-known is that Portland has a long history of segregation, racial violence, and public policy that is often viewed as hostile by the Black residents, especially the Albina neighborhoods of North and inner-Northeast Portland. Since Dr. Gibson published Bleeding Albina: A History of Community Disinvestment in 2007, terms such as gentrification, redlining and restrictive racial covenants have become more common in academic and social parlance concerning Portland. In this thesis, we will explore how gentrification …

The Community Case For Violence: Toward A Materialist Perspective On Community Work, Aven Handley-Merk

University Honors Theses

This paper examines and synthesizes existing critiques of contemporary community work in the United States. These critiques are substantiated and developed by a discussion of nonprofit history and formal structure, establishing the premise that contemporary community work is constrained both by its powerlessness and its collaboration with government. It is constrained to an extent that it cannot meaningfully address or remedy community problems. Theorists often see the root of this problem in the birth of neoliberalism in the 1970s, but this paper argues that it arises instead from liberal philosophy, and is rooted much more deeply in Western history and …

Transportation And Gentrification: Impacts On Low-Income Black Households In Portland, Steven Howland

PSU Transportation Seminars

Portland’s Black population has been heavily impacted by gentrification in the historic Albina community. Nearly half of Portland’s Black population lives in the area east of 82nd Ave, known as East Portland. This has had substantial impacts on both Black households that can continue living in Albina and those living in East Portland. The suburban-esque built environment of East Portland makes it difficult to get around and reach basic necessities. Those living in Albina have taken on exorbitant rents. Both groups suffer from a geographic divide that has made it difficult to rely on family and friends for basic needs …
