Island Platforms And The Hyper-Terrestrialisation Of Singapore's Smart City-State, Orlando Woods, Tim Bunnell, Lily Kong

Research Collection College of Integrative Studies

This paper foregrounds the importance of underlying territorial formations in realising a vision of the smart city. It argues that as a political technology of the state, territory should be understood as a platform upon which data works and the smart city unfolds. In this view, island territories – of which bordered city-states like Singapore provide paradigmatic examples – provide an integral, yet hitherto unexplored, component in the realisation of urban “smartness”. We illustrate these theoretical arguments through an analysis of how the territorial constraints that characterise Singapore’s island platform enable the state to accurately and effectively realise its vision …

Forests Are Chill: The Interplay Between Thermal Comfort And Mental Wellbeing, Loïc Gillerot, Kevin Rozario, Pieter De Frenne, Rachel Oh, Quentin Ponette, Aletta Bonn, Winston Chow, Et Al.

Research Collection College of Integrative Studies

As global warming and urbanisation intensify unabated, a growing share of the human population is exposed to dangerous heat levels. Trees and forests can effectively mitigate such heat alongside numerous health co-benefits like improved mental wellbeing. Yet, which forest types are objectively and subjectively coolest to humans, and how thermal and mental wellbeing interact, remain understudied. We surveyed 223 participants in peri-urban forests with varying biodiversity levels in Austria, Belgium and Germany. Using microclimate sensors, questionnaires and saliva cortisol measures, we monitored intra-individual changes in thermal and mental states from non-forest baseline to forest conditions. Forests reduced daytime modified Physiologically …

Do Americans Support More Housing?, Michael Lewyn

Scholarly Works

An analysis of opinion poll data on housing issues. The article finds that Americans generally believe that their community needs more housing of all types, but are more closely divided about whether such housing should be in their own neighborhoods. The article further finds that members of minority groups, lower-income Americans, and younger Americans are more pro-housing than older, affluent whites.

What Drives Housing Choices Of Refugees And Immigrants?, Diane Mitschke, Anne Nordberg, Stephen Mattingly, Katherine Kitchens, Yasmin Al-Zubi, Farah Naz

TREC Project Briefs

When newcomers to the US initially settle, if their chosen location does not meet their expectations or needs, that often propels them to relocate. To determine what helps drive those transition decisions, the researchers interviewed people if they fulfilled one of these requirements:

• They were members of the Dallas County community who were planning to move in the next five years.

• They had recently (within the past five years) moved from their initial residence following their arrival in Dallas County.
• They also had to be immigrants to or refugees in the US who were at least eighteen years old. Out …

Housing Choice, Transportation Equity, And Access To Opportunities In Refugee And Immigrant Communities, Diane Mitschke, Anne Nordberg, Stephen Mattingly, Katherine Kitchens

TREC Final Reports

Mobility directly impacts access to opportunities for all protected classes; however, transportation planning and public transit agencies and housing authorities rarely coordinate affordable housing and the transportation system planning decisions. This lack of coordination often leads to mismatches between access to opportunities and affordable housing. Safe access to employment, quality schools, and healthcare represent a few of the many factors that may influence housing choice. For most households with budget constraints, all of these factors may not be achievable. While existing research documents the mismatch between affordable housing and access to opportunities, the role that mobility plays in residential selection …

App-Based Data Collection To Characterize Latent Transportation Demand Within Marginalized And Underserved Populations, Noelle L. Fields, Courtney Cronley, Stephen Mattingly, Nicole Iroz-Elardo, David Levine, Nithisha Gudipati, Cristine Highfill, Mary Kris Stringfelllow, Anna O'Dell, Rebecca Cole, Melody Huslage

TREC Final Reports

Our interdisciplinary team refined an app prototype, MyAmble, to gather data related to quantity of transportation disadvantage and latent demand, and to identify psycho-social-economic corollaries. MyAmble utilizes a traditional travel diary format but expands the type of trips measured to include 1) completed trips, 2) missed trips, and 3) latent travel demand. The app also measures the real-time perceived impact of transportation behaviors (realized and latent) on participants’ physical health, mental health, social engagement, and employment/academics. Finally, the app has a text-messaging feature, Travel Buddy, that is used to increase participant engagement and retention over longitudinal data collection. The project …

Riverview Community Park Commoning Plan, Haley B. Keene

Master of Urban and Regional Planning Capstone Projects

Riverview Community Park began as an illegal DIY skatepark in the Maymont neighborhood of Richmond, Virginia. Now, although it is a city park, it is still entirely managed by volunteer community groups (skateboarders, the neighborhood Civic League, and a community garden) who view the park as a creative, experimental community-led spatial project. Due to a dearth of communication between the three groups, the park has suffered political strife between the groups and a chaotic physical atmosphere. This plan utilizes a commons governance framework and participatory, asset-based community design to usher in a new era of enhanced collaboration, common narratives, and …

An Analysis Of Racially Disparate Impacts On Housing For The City Of Tukwila, Washington, Neil Tabor

Community and Regional Planning Program: Professional Projects

The housing crisis within the Pacific Northwest of the United States has prompted action from Washington legislators, resulting in Governor Inslee identifying housing as a key priority and the legislature passing a number of forward-thinking bills in the last half decade, requiring the allocation of more resources, and asking more of jurisdictions to address current housing needs and anticipated future growth. Layered within the planning efforts for future growth are concerns and considerations for the potential of new housing development to perpetuate and exacerbate societal inequities built on discriminatory housing policies and practices of generations past and present. In an …

A Bike System For All In Silicon Valley: Equity Assessment Of Bike Infrastructure In San José, Ca, Ahoura Zandiatashbar, Jochen Albrecht, Hilary Nixon

Mineta Transportation Institute

Investing in sustainable, multimodal infrastructure is of increasing importance throughout the United States and worldwide. Cities are increasingly making strategic capital investment decisions about bicycle infrastructure—decisions that need planning efforts that accurately assess the equity aspects of developments, achieve equitable distribution of infrastructures, and draw upon accurate assessment methods. Toward these efforts, this project uses a granular bike network dataset with statistical and geospatial analyses to quantify a bike infrastructure availability score (i.e., bike score) that accounts for the safety and comfort differences in bike path classes in San José, California. San José is the 10th largest U.S. city and …

Understanding Connections Between Mobility, Transportation, And Quality Of Life In Refugee Communities In Tucson, Arizona, Orhon Myadar, Arlie Adkins, Maia Ingram, Nicole Iroz-Elardo

TREC Final Reports

In this multidisciplinary research project we aimed to study mobility challenges that refugees in Tucson, AZ, experience after their resettlement. Using qualitative and quantitative data collected from interviews and survey data, we argue that mobility shapes the ways refugees foster social connections, attain employment and access educational opportunities. Accordingly, barriers to mobility negatively impact refugees’ perception of well-being in post resettlement. However, these challenges are not experienced evenly. Nor are refugees passive subjects who lack agency in overcoming various barriers they experience. The study reveals the resilience of the refugee community in navigating the intersectional challenges they confront related to …

State Of Urbanization In Nepal: The Official Definition And Reality, Keshav Bhattarai, Ambika P. Adhikari, Shiva Gautam

Himalayan Research Papers Archive

Nepali government’s official delineation of several human settlements as new urban areas has been questionable because many important criteria such as urban infrastructure and services, open space, population density and economic viability are not thoroughly analyzed while defining what is urban. Many settlements in Nepal officially defined as urban, often driven by political considerations, are operating in the rural framework forming ruralopolises. This paper analyzes various criteria needed for defining urbanization that are internationally accepted to assess Nepal’s official definition of urban settlements. Urban areas have been expanding in Nepal at the cost of agricultural, forest, and shrubland land uses. …

An evidence-based analysis will guide a tree planting framework along 82nd Avenue from I-84 to Foster-Powell. The final report will include policies supporting tree canopy development, strengthening the coalition's Portland Clean Energy Fund application, fostering collaboration between landowners and government agencies, and promoting tree preservation strategies.

Transportation Behavior Among Older Vietnamese Immigrants In The Dallas-Fort Worth Metroplex: Well-Being, Geospatial Mobility, And Potential Indicators For Ride Providers’ Geospatial Burden, Rebecca L. Mauldin, Stephen Mattingly, Mahshid Haque, John P. Connolly, Latisha Thomas, Zachary Tarbet, Farzana Chowdhury, Rupal Parekh

TREC Final Reports

Nearly 4.6 million immigrants aged 65 and older live in the United States. This population is expected to more than triple in size by 2050. A lack of culturally appropriate transportation solutions for older immigrants creates disparities in access to services for older immigrant populations, increasing their risk of social isolation and reduced physical and mental health. A growing number of older immigrants live in low-density urban environments, which are characterized by high automobile dependency and limited public transportation. In these environments, older immigrants are likely to depend on others to provide private transportation. Negative aspects of this reliance on …

Sustaining Multimodal Choices: Examining Travel Behavior For Non-Work Trips Beyond Covid-19, Yizhao Yang, Rebecca Lewis

TREC Final Reports

Increasing the usage of sustainable travel modes requires changes in both environmental and psychological dimensions. A knowledge gap exists concerning the mechanism via which various factors interact to shape travel decision. Gaining such knowledge requires our ability to examine people’s behavioral adjustment in reaction to environmental and psychological changes or interventions.

This project uses COVID-19 as a natural experiment, treating the significant disruption induced by the pandemic as an intervention to study changes in travel behaviors and adoption of different travel choices following the COVID pandemic. This project builds upon a 2020 study conducted by the PI’s. It adopts a …

Exploring The Association Of Brownfield Remediation Status With Socioeconomic Conditions In Wayne County, Mi, Brendan F. O'Leary, Alex B. Hill, Colleen Linn, Mei Lu, Carol J. Miller, Andrew Newman, F. Gianluca Sperone, Qiong Zhang

Urban Studies and Planning Faculty Research Publications

Urban neighborhoods with locations of environmental contamination, known as brownfields, impact entire neighborhoods, but corrective environmental remedial action on brownfields is often tracked on an individual property basis, neglecting the larger neighborhood-level impact. This study addresses this impact by examining spatial differences between brownfields with unmitigated environmental concerns (open site) and sites that are considered fully mitigated or closed in urban neighborhoods (closed site) on the US census tract scale in Wayne County, MI. Michigan’s Department of Environment, Great Lakes, and Energy’s leaking underground storage tank (LUST) database provided brownfield information for Wayne County. Local indicators of spatial association (LISA) …

Youth Perceptions And Constructions Of Urban Space In Morocco, Hadwynne Gross

Independent Study Project (ISP) Collection

Moroccan urban spaces are influenced by 800 years of history, and in particular, legacies of colonialism. This research seeks to examine urban space in Morocco through the lens of youth between the ages of 18 and 25 in the capital city of Rabat. Inspired by the book The Image of the City by Kevin Lynch, this research uses a variety of qualitative methods, namely a semi- structured interview and two mental mapping exercises, to explore how youth in Rabat perceive the city’s ability to both adhere to its historical roots and adapt to a rapidly changing world. Exploring urban geography …

Property Pillagers: Effects Of Dirty Urbanism, Chase Wilson, Kayli Clark

Belmont University Research Symposium (BURS)

This podcast dives into American urbanism and its associated development targeting certain minority communities; the ill intentions to disrupt specific neighborhoods led us to refer to the practice as “dirty urbanism”. The pair of I-40 and Jefferson Street in north Nashville, alongside similarly treated areas across the United States, exemplify dirty urbanism. Exercising their raw power and ability to cover up to 90% of the costs, the federal government incentivizes the local governments to construct the highway system: a highway system used as a racially motivated tool to sever black-built urban fabrics. With the highways, vehicular space overrides …

Pedestrian Behavior Study To Advance Pedestrian Safety In Smart Transportation Systems Using Innovative Lidar Sensors, Taylor Li, Sirisha M. Kothuri, Katherine L. Keeling, Xianfeng Terry Yang, Farzana R. Chowdhury

TREC Final Reports

Pedestrian safety is critical to improving walkability in cities. Although walking trips have increased in the last decade, pedestrian safety remains a top concern. In 2020, 6,516 pedestrians were killed in traffic crashes, representing the most deaths since 1990 (NHTSA, 2020). Approximately 15% of these occurred at signalized intersections where a variety of modes converge, leading to the increased propensity of conflicts. Current signal timing and detection technologies are heavily biased towards vehicular traffic, often leading to higher delays and insufficient walk times for pedestrians, which could result in risky behaviors such as noncompliance. Current detection systems for pedestrians at …

Rural Gentrification And The Spillover Effect: Integrated Transportation, Housing, And Land Use Challenges And Strategies In Gateway Communities, Danya Rumore, Philip Stoker

TREC Final Reports

Small towns and cities near national parks, public lands, and other natural amenities throughout the West are experiencing rapid growth and increased visitation. These “gateway communities” comprise a significant portion of the rural West, constituting about 31% of all communities and more than 60% of those under 25,000 people. Our prior NITC-funded research shows that growth and increased tourism create a range of “big city challenges” for gateway communities, particularly a significant increase in housing prices, which pushes the local workforce to outlying areas and other rural communities. As a result, despite being small towns, many developed gateway communities have …

Network Effects Of Disruptive Traffic Events, Juan Medina, Xiaoyue Cathy Liu

TREC Final Reports

Current traffic management strategies are based on expected conditions caused by recurring congestion (e.g., by time of day, day of week), and can be very effective when provisions are also given for reasonable variations from such expectations. However, traffic variations due to non-recurrent events (e.g., crashes) can be much larger and difficult to predict, making also challenging efforts to identify, measure, and forecast their disruptive effects. This project explores a proactive approach to deploy a tool for managing non-recurrent congestion by identifying and quantifying the effects of disruptive traffic events at a microscopic level using a comprehensive set of data …

New Lidar System Pinpoints Pedestrian Behavior To Improve Eficiency And Safety At Intersections, Taylor Li, Sirisha M. Kothuri, Xianfeng Terry Yang

TREC Project Briefs

Pedestrian safety is critical to improving walkability in cities. To that end, NITC researchers have developed a system for collecting pedestrian behavior data using LiDAR sensors. Tested at two intersections in Texas and soon to be tested at another in Salt Lake City, Utah, the new software created by a multi-university research team is able to reliably observe pedestrian behavior and can help reduce conflicts between pedestrians and vehicles at signalized intersections. The Utah Department of Transportation (UDOT) is already working on implementing this new LiDAR system to improve data collection at intersections.
