Large-Scale Dataset for Radio Frequency-Based Device-Free Crowd Estimation

open access: yesData, 2020
Organisers of events attracting many people have the important task to ensure the safety of the crowd on their venue premises. Measuring the size of the crowd is a critical first step, but often challenging because of occlusions, noise and the dynamics ...

A configurable agent-based crowd model with generic behaviour effect representation mechanism [PDF]

open access: yes, 2014
Most of the existing crowd models were designed for specific behaviors or scenarios (e.g., emergency evacuations and bi-directional crowd flows). Significant modifications were often required to accommodate new behaviors or new scenarios.
