Agent-Based Modelling of Forces in Crowds
نویسندگان
چکیده
Recent events have highlighted the importance of good models of crowds, however many existing crowd models are either computationally inefficient, or are missing a crucial human behaviour in crowds: local pushing. After discussing some essential aspects of force in crowds, and considering some existing models, we propose an efficient agent-based model of crowd evacuation that incorporates pushing forces and injuries. Basing our model on existing work, we note several problems associated with crowd density in an existing model and recommend solutions. Analysis of our model shows significant effects of force on the crowd, as well as significant effects of crowd density when measuring the number of agents still trapped inside the space after a fixed time.

Modelling Driver Interdependent Behaviour in Agent-Based Traffic Simulations for Disaster Management
Accurate modelling of driver behaviour in evacuations is vitally important in creating realistic training environments for disaster management. However, few current models have satisfactorily incorporated the variety of factors that affect driver behaviour. In particular, the interdependence of driver behaviours is often seen in real-world evacuations, but is not represented in current state-of...
متن کاملInvestigating Crowd Behaviour during Emergency Evacuations Using Agent-Based Modelling
In the present paper we argue that the effectiveness of interventions/design solutions supporting emergency evacuation of crowds in socio-technical systems, depends on the appropriateness of the models used for the crowd behaviour. After reviewing basic approaches already used to model escaping crowds, the knowledge about crowd behaviour provided by modern social psychology is briefly presented...
متن کاملAgent-Based Simulation of Traffic Jams, Crowds, and Supply Networks Reality, Simulation, and Design of Intelligent Infrastructures
Human behavior is normally very hard to describe, as the relevant variables are difficult to identify, to quantify, and to measure. However, scientists have recently discovered several natural constants and laws in pedestrian crowds and vehicle traffic, starting from propagation velocities of traffic jams and Mexican waves, over human trail formation, scaling laws in traveller behavior, interac...
متن کاملFundamentals of Pedestrian and Evacuation Dynamics
Multi-Agent Simulation is a general and powerful framework for understanding and predicting the behaviour of social systems. Here we investigate the behaviour of pedestrians and human crowds, especially their physical movement. Our aim is to build a bridge between the multi-agent and pedestrian dynamics communities that facilitates the validation and calibration of modelling approaches which is...
متن کاملAutomatic rule identification for agent-based crowd models through gene expression programming
Agent-based modelling of human crowds has now become an important and active research field, with a wide range of applications such as military training, evacuation analysis and digital game. One of the significant and challenging tasks in agent-based crowd modelling is the design of decision rules for agents, so as to reproduce desired emergent phenomena behaviors. The common approach in agent...
