TraversRL: Traversable Pedestrian Pathway Generation With Reinforcement Learning
Bin Han, Robert Wolfe, Bill Howe
Automatically generating pedestrian pathways from aerial images requires producing a connected network suitable for routing, not just detecting where sidewalks appear. Sidewalks an…
Can Large Language Models Integrate Spatial Data? Empirical Insights into Reasoning Strengths and Computational Weaknesses
Bin Han, Robert Wolfe, Anat Caspi +1
We explore the application of large language models (LLMs) to empower domain experts in integrating large, heterogeneous, and noisy urban spatial datasets. Traditional rule-based i…
Reliable, Routable, and Reproducible: Collection of Pedestrian Pathways at Statewide Scale
Yuxiang Zhang, Bill Howe, Anat Caspi
While advances in mobility technology including autonomous vehicles and multi-modal navigation systems can improve mobility equity for people with disabilities, these technologies…
Towards Zero-Shot Annotation of the Built Environment with Vision-Language Models (Vision Paper)
Bin Han, Yiwei Yang, Anat Caspi +1
Equitable urban transportation applications require high-fidelity digital representations of the built environment: not just streets and sidewalks, but bike lanes, marked and unmar…
PathwayBench: Assessing Routability of Pedestrian Pathway Networks Inferred from Multi-City Imagery
Yuxiang Zhang, Bill Howe, Sachin Mehta +2
Applications to support pedestrian mobility in urban areas require a complete, and routable graph representation of the built environment. Globally available information, including…
Laboratory-Scale AI: Open-Weight Models are Competitive with ChatGPT Even in Low-Resource Settings
Robert Wolfe, Isaac Slaughter, Bin Han +8
The rapid proliferation of generative AI has raised questions about the competitiveness of lower-parameter, locally tunable, open-weight models relative to high-parameter, API-guar…
Top-down Green-ups: Satellite Sensing and Deep Models to Predict Buffelgrass Phenology
Lucas Rosenblatt, Bin Han, Erin Posthumus +2
An invasive species of grass known as "buffelgrass" contributes to severe wildfires and biodiversity loss in the Southwest United States. We tackle the problem of predicting buffel…
