More Roads Or Public Transit? Insights From Measuring City-Center Accessibility, Lucas Conwell, Fabian Eckert, Ahmed Mushfiq Mobarak

Discussion Papers

We propose a theory-inspired measure of the accessibility of a city’s center: the size of the surrounding area from which it can be reached within a specific time. Using publicly-available optimal routing software, we compute these ”accessibility zones” for the 109 largest American and European cities, separately for cars and public transit commutes. Compared to European cities, US cities are half as accessible via public transit and twice as accessible via cars. Car accessibility zones are always larger than public transit zones, making US cities more accessible overall. However, US cities’ car orientation comes at the cost of less green …

What The Latest Science On Impacts, Adaptation And Vulnerability Means For Cities And Urban Areas, I Adelekan, A. Cartwright, Winston T. L. Chow, Et Al See Comments For Full List Of Authors

Research Collection College of Integrative Studies

The Summary for Urban Policymakers (SUP) Volume II focuses on impacts, adaptation and vulnerability in cities and urban areas. Drawing on latest research, this volume summarises key findings of the IPCC Working Group II Report for urban policy makers. The scale, reach, and complexity of contemporary urbanization compounds climate risks and conditions adaptation. While cities are embedded in diverse regional contexts and differentially exposed to climate risks, they present key opportunities for a more rapid transition to equitable and climate-resilient development. This volume highlights how cities and regions are a primary locus for innovation and societal choices towards adaptation solutions …

Harmonized Gap-Filled Datasets From 20 Urban Flux Tower Sites, Matthew Lipson, Sue Grimmond, Martin Best, Winston T. L. Chow

Research Collection College of Integrative Studies

A total of 20 urban neighbourhood-scale eddy covariance flux tower datasets are made openly available after being harmonized to create a 50 site–year collection with broad diversity in climate and urban surface characteristics. Variables needed as inputs for land surface models (incoming radiation, temperature, humidity, air pressure, wind and precipitation) are quality controlled, gap-filled and prepended with 10 years of reanalysis-derived local data, enabling an extended spin up to equilibrate models with local climate conditions. For both gap filling and spin up, ERA5 reanalysis meteorological data are bias corrected using tower-based observations, accounting for diurnal, seasonal and local urban effects …

Refining The Nutrition Environment Measures Survey (Nems) For Healthy Community Stores: Adaptations To Capture Alternative Food Retailers And Align With Dietary Guidelines, Alex B. Hill, Ravneet Kuar, Samantha M. Sundermeir, Christina Kasprzak, Megan Winkler, Sara John, Rachael D. Dombrowski, Bree Bode, Joel Gittelsohn

Urban Studies and Planning Faculty Research Publications

Inadequate consumption of healthy food is an ongoing public health issue in the United States. Food availability measures of supply versus consumption of healthy foods are disconnected in many studies. There is a need for an objective assessment of the food environment in order to assess how the food supply aligns with the Healthy Eating Index (HEI). Data were collected as part of the Healthy Community Stores Case Study Project, including a refined Nutrition Environment Measures Survey for Healthy Community Stores (NEMS-HCS) and an updated Healthy Food Availability Index that aligns with the Healthy Eating Index (HFAHEI). This paper will …

Speed Management And Speed Reduction In Portland, Or, Jason C. Anderson, Clay Veka

PSU Transportation Seminars

In 2015, the Portland City Council unanimously passed a resolution committing Portland to Vision Zero, the goal to eliminate traffic deaths and serious injuries. An underpinning of Vision Zero is that streets are managed for safe speeds. This presentation will summarize Portland's speed management process, how it relates to achieving Vision Zero, and present two case studies in which speed limits were reduced: (1) a 25 mi/h to 20 mi/h reduction on residential streets and (2) various reductions on arterials and collectors. Reduction sites in which additional treatments were implemented, such as speed humps and fixed speed safety cameras, will …

Environmental And Social Conflict In The Urban Context: An Analysis Of Waste Management In Hanoi, Nam Hoang

Student Research

The resistance movement regarding the operation of Nam Sơn Waste Processing Center – one of the main landfills in Hanoi – has for over twenty years been a significant challenge to the city. Considering the resistance among local communities as a natural and environmental conflict, this project will attempt to discover the sources, dynamics, and outcomes of the conflict. The continuing reproduction of local resistance despite authority’s efforts to mitigate through negotiations and promises has revealed the complex nature of the conflict, which then required a more comprehensive approach not solely to the direct conflict but also to the system …

In Favor Of Bringing Game Theory Into Urban Studies And Planning Curriculum: Reintroducing An Underused Method For The Next Generation Of Urban Scholars, Brian Mcdonald Gardner

Dissertations and Theses

By looking at some historical examples of Urban Studies literature and theory (and a detailed dive into Neil Smith's "Toward a theory of gentrification…") this thesis makes the case that Game Theory has valid insights to add to the foundation of Urban Studies and Planning and should be included in Masters and Doctorate level curriculums. As a discipline Game Theory has revolutionized multiple other fields, and can be used both mathematically and/or non-mathematically. It is postulated below that the inclusion of Game Theory would help scholars and practitioners arrive at better outcomes. This case is made by reviewing various areas …

Accessing Opportunities For Household Provisioning Post-Covid-19, Kelly Clifton, Amanda Howell, Kristina M. Currans, Gabriella Abou-Zeid, Max Nonnamaker, Paula C. Carder

TREC Final Reports

In this project, we used a mixed-methods study to collect critical information to evaluate the extent to which people modified their shopping behavior, either by choice or necessity, to meet their provisioning needs during the COVID-19 crisis and the following recovery. First, four waves of a cross-sectional survey were administered online to a representative sample of households in Arizona, Florida, Michigan, Oregon, and Washington. This longitudinal, comparative study responded directly to a critical research gap and advanced behavioral science by providing a rich survey dataset to support and test theories of behavioral change and technology adoption. Second, focus groups were …

Evaluating The Stigma Toward Counseling In The African American Community, Jamaica Chapman

Doctoral Projects

Self-stigma is an important factor that hinders help seeking through the use of mental health services. “Self-stigma is the reduction of an individual’s self-esteem or self-worth caused by the individual self-labeling herself or himself as someone who is socially unacceptable” (Vogel et al., 2006, p. 325). Attitudes have suggested both men and women struggle with depression in this population, and that they are reluctant to addressing psychological problems. Most are overly concerned about the stigma associated with mental illness. Though some are open to seeking treatment through mental health services, religious coping in this community is the most preferred method …

“¿Te Invité Yo A Vivir Aquí?” … Vivir Contra La Pendiente: Resistencia Entre El Mapa Y El Territorio, El Caso Del Cerro Las Cañas, Darlene Guadalupe Valencia

Independent Study Project (ISP) Collection

In the Mega Fire of Valparaíso in 2014, more than 1,000 hectares were burned, leaving 12,500 people not only without their homes, but without their neighborhood. 15 people were killed and more than 500 people were injured. This socio-natural catastrophe was a clear demonstration of the marginality and abandonment in which the peripheral sectors of the urban configuration of the city find themselves. Given that most of the communities that live in these sectors have their homes as a result of “tomas de terrenos”, which is the unauthorized occupation and habitation of land, entails a significant level of vulnerability as …

Aclp - Broadband Planning Tool Kit - October 2022, New York Law School

Reports and Resources

This Tool Kit provides state and local policymakers with a range of resources and analyses for use during broadband planning. The Tool Kit focuses on the array of grant and other funding opportunities available to states and localities as a result of the Infrastructure Investment & Jobs Act, as well as other pandemic-era stimulus programs. However, the Tool Kit is also useful for broadband planning outside of these specific funding programs. Indeed, the Tool Kit offers foundational planning resources that can be used now and in the future by officials, ISPs, and other stakeholders in the broadband space.

From Shared Micro-Mobility To Shared Responsibility: Using Crowdsourcing To Understand Dockless Vehicle Violations In Austin, Texas, Shunhua Bai, Junfeng Jiao

Research Collection College of Integrative Studies

In recent years, many progressive U.S. cities have witnessed the rapid popularization of dockless small vehicles as a car-free travel alternative to meet the short distance travel demand. The research gap exists in revealing the social outcome of the massive influx of shared small vehicles on public space. To that end, this study analyzed 4,100 parking violation reports in Austin, Texas, crowdsourced from the Austin 311 non-emergency service request system. The results showed that sidewalk and other public space intrusions were the two most frequently reported violations. Additionally, it found that improperly parked vehicles in parks required the longest time …

Analysing Impacts Of Urban Morphological Variables And Density On Outdoor Microclimate For Tropical Cities: A Review And A Framework Proposal For Future Research Directions, Shreya Banerjee, Ngai Yan Ching, Sin Kang Yik, Yuliya Dzyuban, Peter Jay Crank, Xin Yi Pek, Winston T. L. Chow

Research Collection College of Integrative Studies

Modifying urban morphology, defined as mass, density, and orientation of building stock in cities, are well-known heat mitigation strategies addressing urban heat islands (UHI) at various scales and consequent thermal discomfort. However, varying morphological aspects may have divergent effects on Outdoor Thermal Comfort (OTC) in cities. Unlike UHI, which is derived from urban-rural temperature differences, OTC can be quantified by thermal comfort indices considering the objective assessment of microclimatic variables including air temperature (Ta), relative humidity (RH), mean radiant temperature (TMRT), and wind speed (Va), as well as a subjective assessment of individual perception. In Singapore and other tropical cities, …

Are There Transit Deserts In Europe? A Study Focusing On Four European Cases Through Publicly Available Data, Yefu Chen, Junfeng Jiao

Research Collection College of Integrative Studies

Public transit has been proven as an affordable travel method, while the inequitable distribution is a rising concern among practitioners and researchers. A transit desert, based on the demand and supply concept in measuring the mismatch in allocating the level of public transit service, has proved its ability to be applied in cases across countries. According to this concept, this study investigated transit deserts in four cases in Europe. Results indicate that the public transit system in Grand Paris and Madrid are superior due to a smaller population living in areas where public transit cannot meet the demand. Moreover, we …

Portland State And The Downtown Portland Plan - 50 Years Later With Ethan Seltzer, Ethan Seltzer

PDXPLORES Podcast

Fifty years ago, the City of Portland developed a plan for the downtown corridor with a radical vision of what a central city could be. The downtown we know today is the result of that plan. In this episode of PDXPLORES, Professor Emeritus Ethan Seltzer discusses the 1972 downtown plan and how Portland State evolved into an urban-serving university alongside the downtown corridor.

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

TREC Final Reports

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 …

Minimizing Surface Run-Off, Improving Underground Water Recharging, And On-Site Rain Harvesting In The Kathmandu Valley, Ambika P. Adhikari, Keshav Bhattarai

Himalayan Research Papers Archive

Nepal's political institutions and administrative units were thoroughly restructured in 2015 with the promulgation of the new Constitution. Several rural areas were combined to meet the definition of urban threshold criteria to classify rural areas into urban categories. Accordingly, over 3,900 local political and administrative units were amalgamated into 753 units, of which, 293 units are classified as urban. Within these newly defined urban areas, many natural environments have been converted into impervious surfaces such as paved roads, sidewalks, and building roofs. These impervious surfaces have drastically increased the amount of surface run-offs-often termed as "urban floods"--under increasing precipitation caused …

The Cultivation Of Social Consciousness In Chinese Urban Communities From The Perspective Of Community Governance : Taking The Community In Shandong As An Example, Li Jie Wang

Lingnan Theses (Doctoral degree)

The social consciousness of residents has been changing since China's reform and opening up. The grassroots governance of the society has also become more and more difficult. In the last decade, the Chinese government has been improving the level of social community governance, and since COVID-19 pandemic, the government has been strengthening democratic social governance. It has become very possible to cultivate social consciousness and democratic consciousness among the residents in the community. I conducted two rounds of questionnaires and three rounds of interviews in several communities in Shandong province.

I interviewed over 30 residents, visited a dozen communities, and …
