Using qualitative reasoning for social simulation of crowds
2013
ACM Transactions on Intelligent Systems and Technology
Preserved Fulltext
In this paper we describe a first attempt to use qualitative reasoning techniques to model demonstrations. ...
We develop qualitative models consistent with the partial, qualitative social science literature, allowing us to model the interactions between different factors that influence violence in demonstrations ...
Thus, we use a qualitative reasoning approach for integrating together these partial models. To the best of our knowledge, QR techniques have never been used for modeling crowd behavior phenomena. ...

Crowd simulation is rapidly becoming a standard tool for evacuation planning and evaluation. ...
We simulated three models: (1) the lattice gas model, (2) the social force model, and (3) the RVO2 model, and obtained the distributions of six observables: (1) evacuation time, (2) zoned evacuation time ...
For example, in a simulation of evacuation, knowledge of the movement of crowds could reveal methods to improve crowd flow and evacuation speed. ...

Commonly used validation methods make strong assumptions about emergence and the importance of crowd structure, leaving a gap in validation literature. ...
Pedestrian and crowd-movement models are difficult to validate using traditional empirical methods because of data-related issues such as generalizability, collection ethics, and costs. ...
An increasingly common way to validate pedestrian models is by comparing videos of real-world or laboratorybased crowds and comparing this qualitative data to simulation results (Kretz et al. (2006) , ...

In simulations, however, the simulated evacuees clogging at exits have behaved non-intelligently, namely they do not give up their exits for better ones for safer egress. ...
This facilitates the approximately equal crowd size at exits for being until the end of the evacuation process, and thereby the model accomplishes more optimal evacuation. ...
