Measuring heat stress and mitigation capacity around transit stops during Vancouver's 2021 heat dome using hyperlocal microclimate simulations

Naser Ahmed, Jed Long, Junghwan Kim, Luyu Liu et autres

Despite the increasing frequency and intensity of heat waves driven by climate change, transportation research and practice have largely overlooked the need for heat-resilient transit planning. To address this gap, this study assesses heat stress and mitigation capacity within the walking catchment …

How Walking-Speed Assumptions Shape 15-Minute City (15-MC) Accessibility Scores: A Case Study of Roanoke, Virginia

Fabiha Rahman, Robert Oliver, Thomas Crawford, Ralph Buehler et autres

In contemporary urban planning, the concept of the 15-min city (15-MC) is gaining significant attention. Prior studies on 15-MC often assume a constant walking speed, regardless of variations in urban topography and individual demographic characteristics. Since 15-MC access is frequently evaluated through …

Digital twins as decision infrastructure: evolution, architecture, and research roadmap

Chaowei Yang, Anusha Srirenganathan Malarvizhi, Yahya Masri, Jennifer Seren Smith et autres

Digital twins (DTs) have evolved from domain-specific simulation tools into integrative cyber–physical–social infrastructures that reshape how complex systems are observed, modeled, and governed. Rather than treating DTs as digital replicas, this paper conceptualizes them as dynamic epistemic architectures that integrate observation, physics-based …

Beyond administrative boundaries: implications of the uncertain geographic context problem for neighborhood research and policy

Seul Lee, Taegeon Kim, Kabsung Kim, Junghwan Kim

Abstract The debate over administrative and experiential definitions of neighborhood boundaries has been a longstanding concern in urban geography and planning. While a substantial body of empirical work has examined administrative, behavioral, and perceptual representations of neighborhoods, these approaches have often been …

Static maps, dynamic threats: re-evaluating U.S. wildfire risk with spatiotemporal clustering

Gunjan Barua, Miguel Pires, Junghwan Kim

Abstract Wildfire (WF) risk in the United States is escalating, yet conventional risk assessment methods often treat this risk as static. This study provides a national-scale comparison of purely spatial and spatiotemporal clustering methods to identify WF hotspots across the contiguous United …

Grounded but Misleading: Evaluating Semantic Alignment in AI-Generated Security Explanations

Heajun An, Connor Ng, Sandesh Sharma Dulal, Junghwan Kim et autres

Online scams increasingly leverage fluent and context-aware social engineering strategies, creating growing demand for AI systems that explain why a message may be risky. However, explanations that cite detector-derived evidence may still semantically weaken or redirect the intended risk interpretation. We introduce …
