The fine – coarse network model for simulating crowd behavior
Journal Title: Computer Science and Mathematical Modelling - Year 2010, Vol 0, Issue 5
Abstract
The paper covers topics concerning the creation of models and simulators of crowd behavior and their usage in decision support systems. Models and crowd behavior simulators were originally created to understand the phenomena occurring in a real crowd. Due to the complexity of observed processes constructed models only chosen aspects are usually described, while others are being generalized or skipped. Creating a model requires making a choice between descriptions which are constant or discret, deterministic or random, and micro or macroscopic. The paper introduces a developed model of crowd movement and behavior allowing a simulation of the movement of large masses of crowd in a city agglomeration environment. In model the representation of environment uses a combination of two approaches: coarse network model and fine network model simultaneously. Using a self-made simulator the author conducted experiments showing advantages and effectiveness of implemented model.
