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

VELOS : a VR platform for ship-evacuation analysis [PDF]

, 2010
Virtual Environment for Life On Ships (VELOS) is a multi-user Virtual Reality (VR) system that aims to support designers to assess (early in the design process) passenger and crew activities on a ship for both normal and hectic conditions of operations ...

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).

An Entropy-Based Combined Behavior Model for Crowd Evacuation

Entropy, 2022
Crowd evacuation has gained increasing attention due to its importance in the day-to-day management of public areas. During an emergency evacuation, there are a variety of factors that need to be considered when designing a practical evacuation model ...

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-

Coordinated crowd simulation with topological scene analysis [PDF]

, 2016
This paper proposes a new algorithm to produce globally coordinated crowds in an environment with multiple paths and obstacles. Simple greedy crowd control methods easily lead to congestion at bottlenecks within scenes, as the characters do not cooperate

A configurable agent-based crowd model with generic behaviour effect representation mechanism [PDF]

, 2014
Most of the existing crowd models were designed for specific behaviors or scenarios (e.g., emergency evacuations and bi-directional crowd flows). Significant modifications were often required to accommodate new behaviors or new scenarios.

Computer Simulation of Leadership, Consensus Decision Making and Collective Behaviour in Humans [PDF]

, 2014
The aim of this study is to evaluate the reliability of a crowd simulation model developed by the authors by reproducing Dyer et al.'s experiments (published in Philosophical Transactions in 2009) on human leadership and consensus decision making in a ...

A Multi-Species Artificial Bee Colony Algorithm and Its Application for Crowd Simulation

IEEE Access, 2019
The artificial bee colony (ABC) algorithm has the problem of slow convergence and may be trapped into local optimum. In this paper, a multi-species ABC (MABC) algorithm is proposed based on the multi-swarm model.
