Vulnerable populations—such as older adults, individuals with disabilities, or patients—often face spatial barriers that limit their independence and participation. We focus on how the built environment can support or hinder mobility, dignity, and access to care.

Using both qualitative and quantitative methods, we evaluate spatial affordances for people with diverse physical and cognitive needs. Our goal is to inform the design of inclusive environments that remove obstacles, enhance navigation, and allow people of all abilities to move safely and confidently within their surroundings.

Integrating visual and community environments in a motorcycle crash and casualty estimation
Kim, Y., Yeo, H., Lim, L., & Noh, B. (2024). Integrating visual and community environments in a motorcycle crash and casualty estimation. Accident Analysis & Prevention, 208, 107792.
Motorcycle crashes pose a serious problem because their probability of causing casualties is greater than that of passenger vehicle crashes. Therefore, accurately identifying the factors that influence motorcycle crashes is essential for enhancing traffic safety and public health. The aim of this study was to address three major research gaps: first, existing studies have relatively overlooked the built environment in relation to visual factors; second, existing crash prediction models have not fully reflected the differences in built environment characteristics between areas with frequent motorcycle crashes and areas with frequent casualties; and third, multidimensional analysis for variable selection is limited, and the interpretability of the models is insufficient. Therefore, this study proposes a comprehensive framework for motorcycle crash and casualty estimation.
Accessible Bus Stops: Evaluating Bus Stop Design Guidelines
for Diverse Transportation-Disadvantaged Groups
Jeong, D., Kim, J., Shrestha, S., Yeo, H., & Lim, L. (2025). Accessible bus stops: evaluating bus stop design guidelines for diverse transportation-disadvantaged groups. Journal of Urban Design, 1-21.
This study conducted a comparative analysis of ten accessible bus stop design guidelines from six countries. Bus stop design standards were evaluated by focusing on crucial bus stop facility components, such as wheelchair pads, tactile indicators, and seating to assess how well these guidelines address the diverse needs of transportation-disadvantaged groups. Most guidelines prioritize accessibility for people with mobility disabilities, particularly wheelchair users, by incorporating wheelchair pads and designated maneuvering areas. Tactile indicators are commonly included for people with visual disabilities, and seating is often provided for older adults. However, standards addressing the needs of marginalized groups, such as people with cognitive and internal disabilities and pregnant women, are minimal or non-existent.
