【摘要】：為完善視野受限時的行人疏散理論,探討了出口指示標(biāo)志在行人疏散中的作用和其他影響疏散的因素。在前人工作的基礎(chǔ)上,進(jìn)一步闡述了視野受限時的疏散理論模型,統(tǒng)計估算了行人的疏散時間;并利用計算機(jī)仿真對比研究了出口指示標(biāo)志在行人疏散過程中的作用。結(jié)果表明,出口指示標(biāo)志能夠明顯地影響行人疏散過程中的動力學(xué)特征,避免了無出口指示標(biāo)志時的盲目和繞行現(xiàn)象,優(yōu)化了行人疏散路徑,提高了疏散效率。同時發(fā)現(xiàn),在不同出口寬度下大的視野距離會對疏散起積極作用;初始行人密度較小時,行人數(shù)量的變化對疏散時間影響不大;初始行人密度較大時,疏散時間與行人數(shù)量間呈線性關(guān)系。
[Abstract]:In order to perfect the theory of pedestrian evacuation with limited visual field, the function of exit sign in pedestrian evacuation and other factors affecting evacuation are discussed. On the basis of previous work, the theoretical model of evacuation with limited vision is further expounded, and the evacuation time of pedestrians is estimated statistically, and the function of exit indication sign in pedestrian evacuation is compared by computer simulation. The results show that the exit sign can obviously affect the dynamic characteristics of pedestrian evacuation process, avoid the phenomenon of blindness and detour when there is no exit indicator sign, optimize the pedestrian evacuation path and improve the evacuation efficiency. At the same time, it is found that large visual field distance will play a positive role in evacuation under different exit widths, and the change of pedestrian number has little effect on evacuation time when the initial pedestrian density is small. When the initial pedestrian density is high, there is a linear relationship between the evacuation time and the number of pedestrians.
