Optimized evacuation route based on crowd simulation [PDF]

Computational Visual Media, 2017
An evacuation plan helps people move away from an area or a building. To assist rapid evacuation, we present an algorithm to compute the optimal route for each local region. The idea is to reduce congestion and maximize the number of evacuees arriving at

An improved social force model (ISFM)-based crowd evacuation simulation method in virtual reality with a subway fire as a case study

International Journal of Digital Earth, 2023
Crowd evacuation simulation using virtual reality (VR) is significant for digital emergency response construction. However, existing evacuation simulation studies suffer from poor adaptation to complex environments, inefficient evacuations, and poor ...

A hybrid model for simulating crowd evacuation [PDF]

New Generation Computing, 2013
Macroscopic and microscopic models are typical approaches for simulating crowd behaviour and movement to simulate crowd and pedestrian movement, respectively. However, the two models are unlikely to address the issues beyond their modelling targets (i.e.,

An Improved Simulation Model for Pedestrian Crowd Evacuation [PDF]

Mathematics, 2020
This paper works on one of the most recent pedestrian crowd evacuation models—i.e., “a simulation model for pedestrian crowd evacuation based on various AI techniques”—which was developed in late 2019. This study adds a new feature to the developed model

An Entropy-Based Combined Behavior Model for Crowd Evacuation [PDF]

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 ...

Simulating crowd evacuation with socio-cultural, cognitive, and emotional elements [PDF]

, 2017
In this research, the effects of culture, cognitions, and emotions on crisis management and prevention are analysed. An agent-based crowd evacuation simulation model was created, named IMPACT, to study the evacuation process from a transport hub.

A Virtual Reality Simulation Method for Crowd Evacuation in a Multiexit Indoor Fire Environment

ISPRS International Journal of Geo-Information, 2020
Evacuation simulations in virtual indoor fire scenes hold great significance for public safety. However, existing evacuation simulation methods are inefficient and provide poor visualized when applied to virtual reality (VR) simulations.

The study on mechanical model considering optimal self-adaption in the bottleneck area [PDF]

Heliyon
It aims to solve the problem that the evacuation state of pedestrians depicted by the traditional social force model in a crowded multiexit scenario has a relatively large difference with the actual state, especially the 'optimal path' considered by the ...

Robot-Assisted Crowd Evacuation Algorithm Based on Deep Spatio-Temporal Q-network [PDF]

Jisuanji gongcheng, 2021
The application of robots to crowd evacuation is limited by the low flexibility, low scenario adaptability, and low evacuation efficiency of robots.To address the problem, this paper proposes an algorithm for robot-assisted crowd evacuation based on deep
