Data Clouds: Segmenting Favelas

Proposed a scalable framework for the 3D scene understanding of favelas using high-resolution point clouds collected with wearable LiDAR devices and a random forest-based 3DMASC classification model.

Japan Uniqueness

Explored the limitations in how ChatGPT introduces environmental justice issues in 3,108 counties in the contiguous US, particularly in disadvantaged counties.

Adopting Visual GenAI

Revealed substantial inadequacy in the spatial coverage and variability in the temporal ranges of GSV images in 45 small/medium sized US cities, calling for attention to such methodological limitation.

Green Exposure Inequalities

Redesigned urban elements considering citywide adoption of autonomous vehicle, and suggested a novel â€˜patchwork’ concept that merges the design strategies into a connected system.

#generative AI #built environment auditing

LLM Urban Audits

Developed an index that consists of the NDVI, distance to adjacent street segment, and street network characteristics, which enables a human-centered evaluation of access to green spaces.

#urban vibrancy #street typology

Urban Street Clusters

Displayed people’s collective cognitive perception of urban space using text information from user-generated contents.

#place identity #generative AI

Place identity: a Generative AI’s Perspective

Captured place identity of 64 global cities through the words and eyes of generative AI (ChatGPT and DALL·E), being one of the first to explore its capabilities in describing place-specific meanings.

Environmental Justice in ChatGPT

Explored the limitations in how ChatGPT introduces environmental justice issues in 3,108 counties in the contiguous US, particularly in disadvantaged counties.

#data equity #google street view

Spatiotemporal Equity of GSV

Revealed substantial inadequacy in the spatial coverage and variability in the temporal ranges of GSV images in 45 small/medium sized US cities, calling for attention to such methodological limitation.

Crowd-sourced Cognitive Mapping

Displayed people’s collective cognitive perception of urban space using text information from user-generated contents.

#human-robot coexistence #global survey #video stimuli

Robot City

A global online survey to investigate the public perception and social acceptance of robots in urban public spaces using AI-generated video stimuli. As robots enter daily life in cities around the world, how should we prepare ourselves to the new normal of ‘human-robot coexistence’?

#pedestrian behavior #urban shade #video analytics #heat adaptation

Shade Chaser

Used video analytics to track nearly 15,000 pedestrian movements in 50 summer days in Kabukicho, Tokyo, and 1) identified an apparent temperature threshold of 36°C at which urban shade becomes a critical heat refuge, and 2) found that behavioral adaption is most evident with 10-30% shade coverage.
