Latent Active Transportation Methodology, Maria Chierichetti, Fatemeh Davoudi Kakhki

Mineta Transportation Institute

Understanding and estimating latent demand for active transportation, such as walking and cycling, is essential for designing infrastructure and policies that promote sustainable mobility. Unlike traditional demand models that focus on observed trips, latent demand estimation seeks to quantify the unrealized potential for active travel due to barriers such as inadequate infrastructure, safety concerns, or lack of connectivity. This study develops a comprehensive latent demand model tailored for California, integrating geospatial analysis and multimodal accessibility assessments. The methodology employs a GIS-based corridor analysis approach, utilizing spatial accessibility metrics and distance decay functions to evaluate potential demand. It incorporates employment and …

Housing Affordability Impacting Factors In U.S. Urban Areas From 2010 To 2020: An Empirical Review Of Theoretical Factors, Colby Lee Woodson

Community and Regional Planning Program: Theses

This study examines housing affordability in United States Combined Statistical Areas (CSAs) and counties from 2010 to 2020, using American Community Survey and Building Permits Survey data. It evaluates theoretical frameworks from George Galster and Kwan Ok Lee. Using a multiscalar approach, affordability is assessed through a costs-over-income ratio, incorporating both supply- and demand-side factors. A novel contribution is the integration of elder dependency rates, which limit housing turnover and exacerbate supply constraints. Findings indicate that rising full homeownership—particularly among older households—has reduced tenure mobility. The study also shows that CSAs offer a stronger analytical resolution than counties. Despite home …

Subway, Collaborative Matching, And Innovation, Yumi Koh, Li Jing, Jianhuan Xu

Research Collection School Of Economics

Using rapid expansion of the Beijing subway from 2000 to 2018, we analyze its impact on collaborative matches in innovations. We find that an hour reduction in travel time between a pair of locations in Beijing brought 14.85% to 37.69% increase in collaborated patents. Far-apart location pairs were more affected, and the local average causal response is approximately 34.92% to 82.29%. The effect is mainly driven by increased matches among highly productive innovators. The entry of new innovators, relocation of existing innovators, and collaborations among low-productive innovators also contribute to the increase in collaborative matches, especially in the long run.

Policymaking And Pretrial Fairness: Evaluating Illinois' Ban On Cash Bail Beyond Chicago, Kaitlyn M. Sims

Global and Public Affairs: Faculty Scholarship

Over 400,000 people are incarcerated awaiting trial each day in the United States. Many of these individuals are held because they are unable to post cash bail, generating substantial economic inequality between those who are able to be released and those who must wait. Illinois's Pretrial Fairness Act (PFA) banned cash bail in 2023 to reduce economic inequity and remove judicial discretion in pretrial decisions. I use daily roster data from multiple suburban and rural Illinois jails and a regression-discontinuity-in-time (RDiT) approach to test for changes to jail composition after the law went into effect. Jail population sizes decreased, though …

Utility-Scale Solar In Virginia – Current Trends And Future Impacts, Damian Pitt, Jennifer M. Ciminelli, Josie Laprad

L. Douglas Wilder School of Government and Public Affairs Publications

Electricity demand is soaring in Virginia, driven largely by the state’s booming data center industry. As the country’s cheapest source of new electricity supply, utility-scale solar (USS) is crucial to meeting this growing need.

Virginia has become a leading state for utility-scale solar development, and USS is projected to provide a substantial percentage of Virginia’s future electricity supply.

Concerns about the impacts of solar development, particularly on farm and forest land, is among the factors leading some localities to reject USS local land-use permits, and/or adopt more restrictive permitting regimes.

This trend towards more restrictive local permitting may threaten the …

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.
