Research on personnel evacuation model considering action mechanism of guiders
In order to study the influence of guiders on the personnel evacuation process,the guidance threshold was intro-duced to quantify the action mechanism of guiders on the pedestrian,and an improved cellular automaton personnel evacuation model considering the dynamic guidance strategy,namely the behavior change guidance mechanism,was proposed.The influ-ence of the number of guiders,the position of guiders and the guidance threshold on the personnel evacuation efficiency was simulated and analyzed.The results show that there is an optimal value range for the number of guiders.The evacuation time is the shortest and the utilization rate of guiders is the most balanced when the position distribution of guiders is homocentric squares shape.When the guiders adopt the behavior change strategy,there is an optimal value of the guidance threshold to make the evacuation efficiency relatively the highest.The research results can provide a theoretical reference for the guiders to adopt the guidance strategy during crowd evacuation.
