A chain navigation grid based on cellular automata for large-scale crowd evacuation in virtual reality

International Journal of Applied Earth Observations and Geoinformation, 2021
Large-scale crowd evacuation simulation in virtual reality is of great significance for emergency response. However, the existing large-scale crowd evacuation simulation methods are challenging to apply to the virtual reality scene.

Entropy-Based Crowd Evacuation Modeling With Seeking Behavior of Social Groups

IEEE Access, 2021
Emergency crowd evacuation, especially in congested indoor scenes, is an important issue in public areas' daily management. Computer simulation is a widely adopted technique to study crowd evacuations and help design reasonable emergence plans due to its

Study on Evacuation Speed based on Psychological panic in Railway Tunnel [PDF]

E3S Web of Conferences, 2020
In order to probe the panic psychology effect on the evacuation characteristics and evacuation efficiency under an emergency such as a fire in a railway tunnel, this paper uses a combination of theoretical derivation and 3D simulation technology to study

Modified Social Force Model Considering Pedestrian Characteristics and Leaders [PDF]

Jisuanji kexue, 2022
Social force model is a classic model in crowd movement simulation.The model expresses the subjective wishes of pedestrians and the interaction between pedestrians in the form of “force”.The model is concise and easy to explain.However,there are many ...

Reasoning about crowd evacuations as emergent phenomena when using participatory computational models

Frontiers in Education, 2023
How do students apply systems thinking to make sense of a computational model of crowd evacuation? We developed a participatory simulation in which users play the role of evacuees that move through a narrow passageway.

Simulating the Effects of Gate Machines on Crowd Traffic Based on the Modified Social Force Model

Mathematics, 2023
Gate machines, such as ticket gates in stations and secure gates in office buildings, are very common in people’s daily lives. On the one hand, the passage between the gates is not wide enough for pedestrians to pass through, which may affect the traffic

Deep reinforcement learning and 3D physical environments applied to crowd evacuation in congested scenarios

International Journal of Digital Earth, 2023
To avoid crowd evacuation simulations depending on 2D environments and real data, we propose a framework for crowd evacuation modeling and simulation by applying deep reinforcement learning (DRL) and 3D physical environments (3DPEs).

Real Time Building Evacuation Modeling with an Improved Cellular Automata Method and Corresponding IoT System Implementation

Buildings, 2022
Facility emergence evacuation is often a complicated process under extreme conditions. Most of the buildings today use pre-installed signages to guide the emergence evacuation.

HDRLM3D: A Deep Reinforcement Learning-Based Model with Human-like Perceptron and Policy for Crowd Evacuation in 3D Environments

ISPRS International Journal of Geo-Information, 2022
At present, a common drawback of crowd simulation models is that they are mainly simulated in (abstract) 2D environments, which limits the simulation of crowd behaviors observed in real 3D environments. Therefore, we propose a deep reinforcement learning-

Placing large group relations into pedestrian dynamics: psychological crowds in counterflow [PDF]

, 2020
Understanding influences on pedestrian movement is important to accurately simulate crowd behaviour, yet little research has explored the psychological factors that influence interactions between large groups in counterflow scenarios.
