Crowd Evacuation Simulation Based on WebGIS

Applied Mechanics and Materials, 2014
In order to improve the efficiency of people evacuation from hazardous regions and reduce the ill effects of disasters, a distributed decision support system for large scale crowd evacuation is proposed. The system is supported by the technology of Web Geographic Information System (WebGIS). Basically, by analyzing the system framework we may acquire a

Towards Web3D-based Lightweight Crowd Evacuation Simulation

The 25th International Conference on 3D Web Technology, 2020
The heterogeneity of the appearance and behavior of the crowd is an important component in a realistic simulation. Using Web3D technology to recreate a large-scale crowd of virtual avatars via the internet is an increasingly important area in crowd studies, especially for emergency crowd evacuation. One major issue in the early development of real-time

Robotic aid in crowd evacuation simulation

2015 7th Computer Science and Electronic Engineering Conference (CEEC), 2015
Evacuating a building in case of emergency can lead to confusion, which in turn can cause a greater risk than the cause of the evacuation. Emergency personnel may be late to give the needed assistance. Robots are more likely to play a key role in recovery efforts.

A Hybrid Model for Simulation of Crowd Evacuation

2014 5th International Conference on Digital Home, 2014
Crowd simulation has been widely used in virtual building evacuation, crowd behavior drilling, movie making, entertainment and many other fields. So far, it is still a difficult problem to synthesize realistic large-scale crowd rendering with an interactive frame-rate in the real-time applications. Therefore, efficiency is a pivotal problem to resolve.

Crowd Evacuation Simulation Using Hierarchical Deep Reinforcement Learning

2021 IEEE 24th International Conference on Computer Supported Cooperative Work in Design (CSCWD), 2021
Data-driven crowd evacuation learning methods are often used to enhance the realism of crowd simulation. However, the learning results of traditional methods cannot adapt to the dynamic changes of the simple scene, and thus have the disadvantage of poor generalization.

Simulation of competitive and cooperative egress movements on the crowd emergency evacuation

Simulation Modelling Practice and Theory, 2021
ABSTRACT Empirical evidence suggests that evacuees tend to break down their well-coordinated motion and adopt competitive egress behaviour when they are confronting life-endangering situations (e.g., fire accident, earthquake). This phenomenon significantly influences crowd dynamics, and subsequently, the overall evacuation time.

Behavior-Based Simulation of Real-Time Crowd Evacuation

2011 12th International Conference on Computer-Aided Design and Computer Graphics, 2011
Emergency evacuation has many applications in computer animation, virtual reality, architecture planning, safety science, etc. However, current methods most focus on the agent-based modeling and simulation. These simulation results can not consider the human behavior fully and their reliabilities are doubtable.

Simulation Analysis of Tunnel Vision Effect in Crowd Evacuation

2021
Excessive cognitive demands, fear, or stress narrow evacuees’ functional fields of view (FFV) in disaster evacuation situations. This tunnel vision hypothesis leads to a new model of evacuee behavior deviating significantly from the previously accepted understanding, and possibly altering conventional evacuation protocol designs.

Simulation and Analysis of the Crowd Evacuation in Subway Station

ICTE 2015, 2015
Taken Shenyang North subway station as an example, the simulation method of successive event was used to analyze the influence of traffic congestion in subway internal environment. First, the crowd evacuation simulation model in subway station was built.

A CPS-Aware Crowd Evacuation Simulation

2020
To effectively carry out disaster prevention and mitigation, it is essential to study the special disaster risk system. When unexpected events occur in disaster cases with large-scale crowd, crowd evacuation is particularly important. Research on safety evacuation of large-scale crowd has been lasted for a long time.
