Pedestrian, Crowd, and Evacuation Dynamics [PDF]

, 2013
This contribution describes efforts to model the behavior of individual pedestrians and their interactions in crowds, which generate certain kinds of self-organized patterns of motion. Moreover, this article focusses on the dynamics of crowds in panic or

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

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

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 ...
