FROM CROWD DYNAMICS TO CROWD SAFETY: A VIDEO-BASED ANALYSIS [PDF]
Advances in Complex Systems, 2008 The study of crowd dynamics is interesting because of the various self-organization phenomena resulting from the interactions of many pedestrians, which may improve or obstruct their flow. Besides formation of lanes of uniform walking direction and oscillations at bottlenecks at moderate densities, it was recently discovered that stop-and-go waves [D.

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

Macroscopic modeling and simulations of room evacuation [PDF]
, 2013 We analyze numerically two macroscopic models of crowd dynamics: the classical Hughes model and the second order model being an extension to pedestrian motion of the Payne-Whitham vehicular traffic model.

Finite Volume approximations of the Euler system with variable congestion [PDF]
, 2017 We are interested in the numerical simulations of the Euler system with variable congestion encoded by a singular pressure. This model describes for instance the macroscopic motion of a crowd with individual congestion preferences.

Placing large group relations into pedestrian dynamics: psychological crowds in counterflow [PDF]
, 2020 Understanding influences on pedestrian movement is important to accurately simulate crowd behaviour, yet little research has explored the psychological factors that influence interactions between large groups in counterflow scenarios.

Recent Developments in Controlled Crowd Dynamics [PDF]
, 2020 We survey recent results on controlled particle systems. The control aspect introduces new challenges in the discussion of properties and suitable mean field limits. Some of the aspects are highlighted in a detailed discussion of a particular controlled particle dynamics.

A Glossary for Research on Human Crowd Dynamics [PDF]
Collective
Dynamics, 2019 This article presents a glossary of terms that are frequently used in research on human crowds. This topic is inherently multidisciplinary as it includes work in and across computer science, engineering, mathematics, physics, psychology and social science, for example.

A system for efficient egress scheduling during mass events and small-scale experimental demonstration [PDF]
Royal Society Open Science, 2020 Improvements in the design of pedestrian facilities have reduced the frequency of crowd accidents, and safety is now generally ensured in well-planned crowd events. However, congestion and inefficient use of infrastructures still remain an issue.

Parameter Estimation of Social Forces in Crowd Dynamics Models via a Probabilistic Method [PDF]
, 2014 Focusing on a specific crowd dynamics situation, including real life experiments and measurements, our paper targets a twofold aim: (1) we present a Bayesian probabilistic method to estimate the value and the uncertainty (in the form of a probability ...

Physics Inspired Methods for Crowd Video Surveillance and Analysis: A Survey
IEEE Access, 2018 Crowd analysis is very important for human behavior analysis, safety science, computational simulation, and computer vision applications. One of the most popular applications is video surveillance that plays an important role in crowd behavior analysis ...
