Improving Urban Planning Through Agent Based Modeling And Q-Learning, Tristan Kalvoda

Scholarly Horizons: University of Minnesota, Morris Undergraduate Journal

This paper explores the use of agent-based modeling (ABM), enhanced by reinforcement learning techniques such as Q- learning, to optimize urban transportation systems. The focus is on modeling and improving aspects such as traffic design, vehicular flow, and pedestrian mobility. The central research question is how to effectively simulate realistic agent behavior in order to develop models that can inform and support policy-making for more efficient and adaptive urban planning. The paper presents and analyzes simulation-based case studies that demonstrate how learning agents can repro- duce realistic movement patterns and provide insights for larger-scale urban systems.

Can Singapore Be A City That Bounces Back And Gives Back?, Lily Kong

Research Collection School of Social Sciences

In a commentary, SMU President Professor Lily Kong called for a widened definition of sustainability in city-making. She proposed that cities must be resilient, regenerative and restorative (3Rs) — able to withstand shocks, replenish ecosystems, and restore human well-being. Prof Kong cited Singapore’s Draft Master Plan 2025 as an illustration of balancing technical innovation with inclusive engagement, stressing that trust is the “invisible infrastructure” of resilience. She also emphasised the role of universities as conveners of dialogue and innovation, spotlighting SMU’s co-convening of the City Dialogues in Vienna and its hosting of the Lee Kuan Yew Global Business Plan Competition, …

The Economic And Environmental Impact Of Shinkansen And High-Speed Rail Infrastructure: A Comparative Analysis Of Economic Growth And Carbon Emissions Reduction, Dillan R. Victory

SPARK Symposium Presentations

The development of Japan's high-speed rail system, the Shinkansen, has played a pivotal role in the country's post-war economic resurgence. Introduced in 1964 with the Tokaidō Shinkansen, this transformative infrastructure investment significantly reduced travel times, bolstered economic activity around station hubs, and facilitated regional development by enabling urban decentralization. This paper explores the long-term economic benefits of high-speed rail, including its impact on land value, business expansion, and carbon emissions. The case study of the Linear Chuo Shinkansen, Japan's latest maglev project, underscores both the economic promise and the political resistance to expansion, particularly in regions such as Shizuoka.

Commercial Property Vacancies In American Cities, Emily Dinh

University Honors Theses

This paper examines the alarming impacts of the vacancy phenomenon on commercial properties across American during and after the COVID-19 pandemic. The increase in remote work encourages people to work from home more frequently. This does not only lessen employees' foot traffic to offices, but also disconnects the engagement of consumers and visitors to public areas, such as malls, stores, and other amenities. Many commercial properties have closed, shrunk their operating spaces, or reallocated for safety and security reasons. Reduction in occupancy rate among mentioned properties influences negatively on business owners, their associated partners, residents of the impacted areas, and …

Planning, Preserving, And Increasing Accessibility: A Reflection On Going “Car-Free”, Abigail J. Weizer

City and Regional Planning

This paper studies the accessibility of car-free areas to those with mobility impairments by examining three car-free and car-lite experiments in California. Whether slowly converted to car-free with long-term, careful planning, or expeditiously changed to car-free during the COVID-19 pandemic, these three car-free experiments show the shortcomings of planning for accessibility in car-free spaces, and how instead of improving accessibility, current planning practice often hinders it. This paper offers a deep-dive into the drawbacks and benefits of going car-free and the ethical and legal reasons why urban planners, designers, and policymakers must consider the accessibility of a space before planning …

Re-Redlining Richmond? Holc Grades, Market-Driven Development, And Resident Satisfaction In Richmond, Va, Addy Cooley

Graduate Research Posters

This study investigates the relationship between historical redlining policies, contemporary market-driven community development strategies, and resident satisfaction and quality of life in Richmond, Virginia. The purpose of the study is to understand the limits of using market-driven indicators to create and evaluate community development plans that seek to correct historical inequities created by redlining. To do so, it compares data from redlining maps used by the Home Owners’ Loan Corporation (HOLC) in 1937 to a 2017 real estate Market Value Analysis (MVA) and a 2014 citywide resident satisfaction survey. Results show a significant, moderate correlation between redlining grades and market …

Climate Adaptation And Risk Preparedness In Florida’S East Coast Cities: Views Of Municipal Leaders, Sheila A. Young, Kenyon C. Lindeman, Samantha R. Fowler

Ocean Engineering and Marine Sciences Faculty Publications

Cities along Florida’s Atlantic coastline are particularly vulnerable to the effects of climate change, posing significant challenges for city planners. How cities see themselves in terms of developing or implementing their climate change adaptation action plans depends, in part, on the extent to which they perceive climate-related events as risks, and their city size. Data were obtained from city leaders (i.e. mayors, city/town managers, or their designees) from 86 cities along Florida’s Atlantic Coast from January to May 2021 to quantitatively assess factors influencing city adaptation planning. Validity and reliability were obtained for the survey. Multiple regression analyses showed significant …

Our Streets: Increasing Equity In Active Transportation Planning Through Community Outreach, Jordan Hoy

Master's Projects and Capstones

ABSTRACT Significant research has demonstrated that active transportation infrastructure is essential for the growth and livability of San Francisco: it increases access to economic opportunities, promotes overall improved public health, encourages mobility without contributing to roadway congestion, prevents traffic injuries and fatalities, and supports the sustainability goals of the city. Despite the fact that communities of color will benefit the most from active transportation infrastructure development, historical disenfranchisement in tandem with a lack of diverse representation within public participation contributes to an inequitable distribution of walking and biking investments throughout the city of San Francisco. While research shows that Black …

Mitigating Urban Heat Island Effect At Southern City Park, Jim Speer

2021 Spring Reports (Sullivan)

The City of Sullivan indicated the southern City Park as an area of interest for redevelopment as a neighborhood area and for sustainable features. There are existing structures and habitats that they are looking to bolster. Students in ENVI 460 identified multiple components of the city park that could be updated and upgraded to provide more sustainable infrastructure and community focus. They recommended permeable pavers in two locations in the park area, green roofing on some existing structures, and adding native habitats to the overall area.

Somewhere That’S Green: Recreational Space Use And Civic Engagement In Massachusetts’ Urban Areas, Matthew Donohue

Honors Program Theses and Projects

Public green spaces, their use, and their accessibility are all crucial indicators of the state of life in urban areas. These spaces can signify the socioeconomic wellbeing of neighborhoods and cities, and often reflect trends accordingly; in one such case, Rehling et al. found in a study in German urban areas that those living at lower socioeconomic levels are often farther from green spaces than those at higher ones.^[1] Perhaps unsurprisingly, access to these spaces is also often an indicator of personal physical health. Rundle et al. found that adults in New York City who lived closer to large …

The Soniferous Experience Of Public Space: A Soundscape Approach, Kenya Dubois Williams

Dissertations and Theses

This research explores the awareness and perceptions of practitioners regarding the role of the soundscape in understanding and managing public spaces. Without considering the role of the soundscape as part of public spaces, urban planners, designers, and policy officials cannot accurately engage in placemaking that provides a complete sensory experience. The antiquated practice of enforcing noise codes has been the traditional approach to mitigate noise (unwanted sounds). However, sound is an overlooked element in the sensory experience of cities and how individuals and communities construct a "sense of place." This study considers the implications of the soundscape approach and soundwalks …

Generation Of 3d Model Of Downtown Sullivan, Jim Speer

2020 Fall Reports (Sullivan)

The City of Sullivan identified the downtown area as an area for improvement and needed a way to depict areas. In ENVI 610, one graduate student was able to address the agreed upon goals of developing a 3D model of the downtown square. Some recommendations for future use of the 3D model were made for land-use planning, drainage systems, elevation, and more.

Webinar: Transportation Benefits Of Polycentric Urban Form, Reid Ewing, Sadegh Sabouri

TREC Webinar Series

A “polycentric” region consists of a network of compact developments connected with each other through high-quality transportation options. Rather than continuing the expanse of low-density development radiating from an urban core, investments can be concentrated on central nodes and transit connections. This development pattern is very popular in Europe and is linked to significant benefits. This presentation is aimed at exploring the academic literature and empirical evidence surrounding polycentric development, analyzing more than 120 regional transportation plans to see how they promote polycentric development, defining types of centers in a hierarchy of centers, quantifying the transportation benefits of polycentric development, …

Expanding The Geography Of Opportunity And Ownership, Maritza E. Mercado Pechin

Richmond Racial Equity Essays: Individual Essays

The author, a city planner, defines an equitable Richmond as a city where all Richmonders have equal or equivalent access to goods, services, status, rights, power, and amenities. She outlines four ideas to help Richmond expand physical and ownership access: rewriting the zoning ordinance; reconnecting the city; establishing programs that increase generational wealth; expanding engagement and education of city planning.

Comparing The Promise And Reality Of E-Scooters: A Critical Assessment Of Equity Improvements And Mode-Shift, Michael Glenn Mcqueen

Dissertations and Theses

In just three years, e-scooters have substantially disrupted and altered the urban mobility landscape. Throughout this period, they have been commonly touted as part of a larger micromobility solution that promises to erase equity barriers and solve the first-mile/last-mile problem. However, few studies in the nascent e-scooter literature have considered these claims. In this study, we surveyed students at Portland State University (n = 1,968) about the role that e-scooters, among other modes, played in meeting their general and university-related travel needs. We then estimated models that incorporated demographics, travel behavior, and latent attitudes distilled using exploratory factor analysis (EFA). …

Economic And Development Benefits Of Fixed Route Transit Through Denser Housing: A National Assessment, Arthur C. Nelson, Robert Hibberd

TREC Project Briefs

Building upon seven years of research, NITC investigators used economic analysis to determine development outcomes and land use planning implications of different fixed route transit systems (FRT). They have created, analyzed, and shared a nationwide data repository that explores links between transit station proximity and real estate rents, jobs, people, and housing. Earlier research revealed important differences in development outcomes of FRT’s during the 2000’s, but the significantly expanded data repository offers a more representative look at development outcomes after the Great Recession and with 22 new FRT systems added.

The main takeaway from this expanded analysis? Only 5% of …

The Link Between Transit Station Proximity And Real Estate Rents, Jobs, People And Housing With Transit And Land Use Planning Implications, Arthur C. Nelson, Robert Hibberd

TREC Final Reports

This report updates and expands prior research in the genre of research that has used economic base analysis (especially shiftshare) and CoStar commercial rent data to estimate the development outcomes to transit. The study period for prior economic base analysis was 2002-2011and census data for 2000 and 2010, as well as CoStar data for 2013. Prior analysis compared development, demographic and housing outcomes associated with those transit systems during the period before the Great Recession (2000 through 2007) and during recession into recovery (2008 through 2011). Though NITC researchers found important differences in outcomes between the study periods of 2000-2007 …

Capturing The Built Environment-Travel Interaction For Strategic Planning: Development Of A Multimodal Travel Module For The Regional Strategic Planning Model (Rspm), Liming Wang, Brian Gregor, Huajie Yang, Tara Weidner, Anthony Knudson

Urban Studies and Planning Faculty Publications and Presentations

Integrated land use and transportation models have evolved along a spectrum from simple sketch planning models to complex microsimulation models. While each has its niche, they are largely unable to balance the flexibility and realism of microsimulation and the speed and interactivity of simple models. The Regional Strategic Planning Model (RSPM) aims to fill this gap by taking a microsimulation approach while making other simplifications in order to model first-order effects quickly. It enables planners to consider the robustness of prospective policies in the face of future uncertainties by accepting a broad range of inputs and allowing rapid simulations of …

Barriers To “New Mobility”: A Community-Informed Approach To Smart Cities Technology, Aaron Golub, Vivian Satterfield

PSU Transportation Seminars

There is an active debate about the potential costs and benefits of emerging “smart mobility” systems, especially in how they will serve communities already facing transportation challenges. This presentation will describe the results of an assessment of these equity impacts in the context of lower-income areas of Portland, Oregon, based on a mixture of quantitative and qualitative research.

Portland, Oregon’s proposal for the U.S. Department of Transportation’s Smart City Challenge, “Ubiquitous Mobility for Portland,” focuses on developing mobility solutions that would serve traditionally underserved populations (low-income, communities of color, and residents with mobility challenges). This study found that by lowering …

Paradoxes Of Violence: A Post-Colonial 'Gaze' On Chicago's Segregation, Zackary Rupp

Cultural Studies Capstone Papers

Although post-colonial theory was developed to examine the legacy of colonial powers, this project proposes that post-colonial theory can nonetheless fruitfully be used for a literary analysis of the Fair Housing Act to account for the typically non-colonial legacy of US segregation. Even though Chicago is not a city in the colonial context, the post-colonial discourse of violence, territorialization, and citizenship are useful tools for understanding the language in legislation that shaped American systemic segregation. Through a post-colonial lens, the research shifts the individual attention away from the marginalized offender and focuses on systemic othering that has shaped spaces suffering …

Urbanism Next: How Technology Is Changing Our City, Nico Larco

PSU Transportation Seminars

Advances in technology such as the advent of autonomous vehicles (AV’s), the rise of E-commerce, and the proliferation of the sharing economy are having profound effects not only on how we live, move, and spend our time in cities, but also increasingly on urban form and development itself. These new technologies are changing the ease of transport, the role of transit, and the places we spend our time. These changes will have profound effects on cities including large shifts in land use, changes in street design, a potential reduction on the need for parking, a shift on where we choose …

Chinatown Anti-Displacement Community Research Project Report, George Villanueva, Debbie Liu

School of Communication: Faculty Publications and Other Works

The Greater Chinatown area in Chicago (see Figure 1 for map) is rapidly changing because of recent public and private investments. The area continues to attract great interest by developers because of its proximity to downtown, public transportation rail infrastructure, bicycle shares, and its vibrant ethnic culture. Consequentially, Greater Chinatown’s popular real estate market creates concerns about the implications of gentrification (economic and cultural) and potential displacement of existing communities. Community advocates, policymakers, and scholars nationwide point to the displacement in lower-income and ethnic communities resulting from urban revitalization. In particular, Chinatowns across the nation have become part of the …

Metropolitan Centers Mean Smart Growth, Richard D. Margerum, Rebecca Lewis, Keith Bartholomew

TREC Project Briefs

In this study, a multidisciplinary team from the University of Oregon and the University of Utah examined regional metropolitan center programs and policies in the Salt Lake City and Denver regions. The goal of the study was to examine this topic on two levels. First, to learn how and why local governments have adopted the concepts of metropolitan centers over time and the related supporting and constraining factors. Second, to understand how demographics, land use, and transportation choices have changed over time in the designated centers.

Metropolitan Centers: Evaluating Local Implementation Of Regional Plans And Policies, Richard D. Margerum, Keith Bartholomew, Rebecca Lewis, Robert Parker, Stephen Dobrinich

This study examines the programs and policies in the Salt Lake City and Denver regions to examine regional vision influence on local planning and the opportunities and constraints facing centers. The research team analyzed local plans over the past several decades, interviewed planners, and examined demographic, land use and transportation characteristics in select centers across the region. We found that the regional vision had a moderate influence on …

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 …
