Pedestrian dynamics modeling is the computational and mathematical study of how individual people and crowds move through space, encompassing both microscopic approaches that govern each pedestrian's motion through force- or rule-based equations and mesoscopic or macroscopic approaches that characterize collective spatial patterns and flow behaviors. It matters for WiFi/CSI sensing research because accurate movement models provide ground-truth frameworks and simulation baselines against which passive radio-frequency sensing systems can be validated, calibrated, and benchmarked when estimating crowd density, trajectory, and velocity. Key variants include the social force model, which treats pedestrians as particles subject to repulsive and attractive Langevin-style interaction forces, and cellular automata models, which discretize space into adjustable-resolution grids and apply local transition rules to reproduce emergent crowd phenomena such as lane formation and bottleneck congestion.
