What is Clogging and Arching Behavior

Chapter 6
Handbook of Research on Design, Control, and Modeling of Swarm Robotics
In emergency case and when there is dense crowds push forward towards a narrow exit, clogging and arching are observed. The exit becomes clogged and the crowd forms an arch-shape, radiating outwards from the exit.

Abstract
The swarm behavior of pedestrians in a crowd, generally, causes a global pattern to emerge. A pedestrian crowd simulation system must have this emergence in order to prove its effectiveness. For this reason, the aim of this work is to demonstrate the effectiveness of the PHuNAC model (Personalities' Human's Nature of Autonomous Crowds) and also prove that the swarm behavior of pedestrians' agents in this model allows the emergence of these global patterns. In order to validate the approach of this work, the authors compared the simulation system with real data. The conducted experiments show that the model is consistent with the various emergent behaviors and thus it provides realistic simulated pedestrian's behavior.
