The spatial dynamics of urban vegetation and housing prices: Insights from pre- and post-pandemic Chicago using OLS and MGWR models

Published in PLOS ONE, 2025

This study investigates how changes in urban vegetation—before and after the COVID-19 pandemic—affected housing prices across neighborhoods in the Chicago metropolitan area. Using OLS and Multiscale Geographically Weighted Regression (MGWR), the analysis highlights clear spatial disparities in how greenery influences housing values.

A Research on the Influence of the Ui-Sinseol Light Rail Transit on Housing Price : Focusing on the Apartments near the Ui-Sinseol Light Rail Transit

Published in Journal of Korea Planning Association, 2022

This research analyzes the impact of the Ui-Sinseol Light Rail Transit (Ui-LRT) on nearby apartment prices in Seoul. Using multiple regression analysis, the study reveals that while proximity to Ui-LRT stations can influence property values, factors such as other transit options and apartment characteristics play a significant role. The results indicate varying effects across regions, highlighting the complex relationship between urban infrastructure and housing markets.

A study on the impact of Chicago L Train (Elevated Train) accessibility on housing price

Published in AAG Annual Conference, 2024

Although initially a semester project, this study was presented at an academic conference with the support of the University of Illinois at Urbana-Champaign, in recognition of its outstanding research results. This study examines how proximity to Chicago’s L Train impacts housing prices, with a focus on areas within and beyond a 1-mile radius of the stations. Utilizing multiple regression and geographically weighted regression (GWR), the analysis highlights the significant role of transportation infrastructure in shaping local housing markets, revealing both positive and region-specific effects on property values.

A Research on the Influences of the Ui-LRT(Light Rail Transit) on the Prices Surrounding Apartments. 우이신설경전철이 주변 아파트 가격에 미치는 영향에 관한 연구

Published in Korean Association for Housing Policy Studies, 2018

This study expands upon previous research presented by the Korean Regional Development Association by incorporating a broader range of factors to assess the socioeconomic impacts of the Ui-Sinseol Light Rail Transit (LRT) on apartment prices. While it continues to use multiple regression analysis, it delves deeper by examining a more comprehensive set of variables, including apartment characteristics such as size and year of construction, environmental factors, and neighborhood socioeconomic conditions. The study provides a more nuanced comparison between the eastern and western regions, isolating the specific effects of the LRT and considering additional influences, such as Line 4 in the eastern region. The findings highlight that factors like apartment size and proximity to amenities had a greater impact on price changes, particularly in the western region. Through the use of more sophisticated regression models and a larger data set, this research offers deeper insights into how urban infrastructure like the LRT influences housing markets, providing a more detailed understanding of its socioeconomic implications.

A Research on the Impact of the Construction of Ui-LRT(Light Rail Transit) on the Prices of Surrounding Apartments. 우이신설선 건설이 주변 아파트 가격에 미치는 영향에 관한 연구

Published in The Korean Regional Development Association, 2018

This study investigates how the construction and operation of the Ui-Sinseol Light Rail Transit (LRT) affected apartment prices in the surrounding areas. Using multiple regression analysis, it examines how proximity to the LRT stations and local amenities, such as schools, influences housing prices. The study differentiates between the eastern and western areas along the rail line, highlighting that the western region, which lacked alternative transportation infrastructure, experienced more significant price increases due to improved access provided by the LRT. Conversely, the eastern region, served by both the LRT and Line 4, saw a lesser impact from the new rail line. The study also considers the evolution of property prices before, during, and after the LRT’s construction, giving a phased perspective on its influence. This research provides a foundational understanding of how the LRT reshaped real estate prices in the area by improving transportation access.
