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

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 ...
