【摘要】:考慮基于社會力模型的多出口場館的人員疏散問題.首先對社會力模型進(jìn)行改進(jìn),包括個(gè)體之間的相互作用力和他們的相對位置有關(guān),個(gè)體的期望速度隨時(shí)間變化等.然后,針對多出口情形,定義動態(tài)變化的視野范圍,綜合考慮個(gè)體到出口的距離、個(gè)體視野范圍內(nèi)的人數(shù)和人群密度等因素,建立最優(yōu)化模型描述個(gè)體選擇目標(biāo)出口的過程.最后,仿真結(jié)果表明,上述模型可以模擬出多出口的體育場館中的疏散場景,該模型可用于體育場館的建設(shè)評估及為現(xiàn)場指揮預(yù)案的制定提供依據(jù).
[Abstract]:The evacuation problem of multi-exit stadiums based on social force model is considered. Firstly, the social force model is improved, including that the interaction between individuals is related to their relative position, and the expected velocity of individuals varies with time, and so on. Then, considering the distance from individual to exit, the number of people in the field of view and the density of population, the optimization model is established to describe the process of selecting the target exit in the case of multi-export, which defines the horizon of dynamic change and considers the distance from the individual to the exit. Finally, the simulation results show that the above-mentioned model can simulate the evacuation scene in multi-exit stadiums and stadiums. The model can be used to evaluate the construction of stadiums and provide the basis for the formulation of field command plan.
