Staypoint Detection from Noisy Trajectory Data [Experiment Paper]
Lance Kennedy, Hossein Amiri, Yueyang Liu +9
Detecting staypoints from raw trajectory data is fundamental to numerous spatial computing applications. This process transforms raw numeric sequences of geolocations into semantic…
Simulating Public Transit Fare Policies in NYC: An Efficient, Socioeconomic-Aware Framework
Parker Wischhover, Hossein Amiri, Kiara Ha +4
Designing equitable and effective public transit fare policies is challenging due to complex interactions among traveler behavior, multimodal networks, and socioeconomic heterogene…
Mobility Anomaly Generation using LLM-Driven Behavior with Kinematic Constraints
Yueyang Liu, Joon-Seok Kim, Andreas Züfle
Although the study of human trajectory anomalies is critical for advancing spatial data mining, empirical research remains severely hindered by a pervasive lack of ground-truth dat…
The Patterns of Life Human Mobility Simulation
Hossein Amiri, Will Kohn, Shiyang Ruan +6
We demonstrate the Patterns of Life Simulation to create realistic simulations of human mobility in a city. This simulation has recently been used to generate massive amounts of tr…
