Using qualitative reasoning for social simulation of crowds

Natalie Fridman, Gal A. Kaminka
2013 ACM Transactions on Intelligent Systems and Technology  
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.  ...

Qualitative Methods of Validating Evacuation Behaviors [chapter]

Tomoichi Takahashi

Quantitative comparison between crowd models for evacuation planning and evaluation

Vaisagh Viswanathan, Chong Eu Lee, Michael Harold Lees, Siew Ann Cheong, Peter M. A. Sloot
2014 European Physical Journal B : Condensed Matter Physics  
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.  ...

Modeling pedestrian crowd behavior based on a cognitive model of social comparison theory

Natalie Fridman, Gal A. Kaminka
2010 Computational and mathematical organization theory  
Modeling crowd behavior is an important challenge for cognitive modelers.  ...  We propose a novel model of crowd behavior, based on Festinger's Social Comparison Theory (SCT), a social psychology theory known and expanded since the early 1950's.  ...  One CA model for pedestrian movement (Blue and Adler 2000) uses a set of 6 IF-THEN rules which work in parallel for all cells, to simulate the movement of pedestrians in cells.  ...

SUMMIT: A Simulator for Urban Driving in Massive Mixed Traffic [article]

Panpan Cai, Yiyuan Lee, Yuanfu Luo, David Hsu
2020 arXiv   pre-print
SUMMIT is built as an extension of CARLA and inherits from it the physics and visual realism for autonomous driving simulation.  ...  This paper presents SUMMIT, a high-fidelity simulator that facilitates the development and testing of crowd-driving algorithms.  ...  Social force can simulate large crowds, but the quality of interactions are constrained by model simplicity.  ...

Verification and Validation of Evacuation Models – Methodology Expansion Proposition

Robert Lubaś, Marcin Mycek, Jakub Porzycki, Jarosław Wąs

A Hybridized Approach to Validation: The Role of Sociological Research Methods in Pedestrian Modeling

Erika Frydenlund, Terra Elzie, Andrew J. Collins, R. Michael Robinson
2014 Transportation Research Procedia  
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) ,  ...

Incorporating Intelligence into Exit Choice Model for Typical Evacuation

Mohammed Shuaib, Zarita Zainuddin
2017 Sains Malaysiana  
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.  ...  ACKNOWLEDGEMENTS We thank the Al-Imam Muhammad Ibn Saud Islamic University for supporting this work under the project No. 370807.  ...
