Journal ArticleDOI
Path Optimization Study for Vehicles Evacuation based on Dijkstra Algorithm
TL;DR: A dynamic road network model is built for vehicles evacuation based on Dijkstra algorithm and the optimal evacuation path is proposed in three different cases, providing well predictive method and theoretical basis for optimal emergency evacuation path selection and emergency rescue decision in public places.
Journal ArticleDOI
Lattice gas simulation and experiment study of evacuation dynamics
TL;DR: LG models with proper pedestrian speed are capable of simulating the dynamic process of orderly emergency evacuations, and a parameter called ‘exit bias’ is introduced into the model to describe the occupants’ familiarity with different exits in a building.
Journal ArticleDOI
Small-grid analysis of discrete model for evacuation from a hall
TL;DR: The simulation results show that small-grid analysis have reproduced some typical phenomena of evacuation, including jam, block and faster-is-slower, etc. as good as the continuum model, i.e., the social force model, but with high simulation efficiency.
Journal ArticleDOI
A behavior-based model for pedestrian counter flow
TL;DR: A behavior-based lattice-gas model for pedestrian dynamics is presented in this paper, which adopts the behaviorism for mobile robot, and the walk task of pedestrian can be divided into three basic behaviors, i.e., "move", "avoid", and "swirl" basic behaviors.
Journal ArticleDOI
A three-stage evacuation decision-making and behavior model for the onset of an attack
TL;DR: A three-stage model to reproduce a series of complex behaviors and decision-making processes at the onset of an attack, when pedestrians generally do not have clear targets and have to deal with fuzzy information from the attack.
