基于虚拟眼动实验的指向型应急疏散标识布局优化方法

Layout Optimization of the Directional Emergency Evacuation Signs Based on Virtual Reality Eye-Tracking Experiment

  • 摘要: 应急疏散标识是逃生人员能否安全逃生的关键因素之一,但其布局的合理性需要进一步的定量优化研究。以办公楼为实验区,借助虚拟眼动实验,分析了实验区指向型应急疏散标识布局的不合理之处;同时设计有效的修改优化方案,提升了应急疏散标识的指向作用。设计了两组虚拟眼动疏散实验,每组实验由两个实验构成,其中实验组1使用真实疏散标识布局,实验组2作为验证实验,使用修改后的疏散标识布局。对比实验结果可得,实验组2的两个实验较实验组1的疏散时间分别缩短了30.28%和30.99%,期望疏散距离分别缩短了42.67%和40.06%,疏散时间和期望疏散距离均明显改善。实验结果与数据分析证明了实验区域内指向型应急疏散标识修改方法和修改方案的有效性。同时创建了一套新的指向型应急疏散标识布局优化方法和流程。

     

    Abstract: The emergency evacuation sign is one of the key factors that determine whether the personnel can escape safely. The rationality of its layout needs further quantitative optimization research. This paper takes the office building as the experimental area, with the help of the virtual reality eye-tracking experiment, analyzes the unreasonable layout of the directional emergency evacuation signs in the experimental area, and designs an effective modification and optimization scheme to improve the directional function of the emergency evacuation signs.Two groups of virtual eye movement evacuation experiments are designed. Each experiment consists of two experiments, in which the experimental group 1 uses the real evacuation sign layout, and the experimental group 2 uses the modified evacuation sign layout as the verification experiment. Compared with the experimental data, the evacuation time of the two experiments in experimental groups 1 and 2 was reduced by 30.28% and 30.99%, and the expected evacuation distance was reduced by 42.67% and 40.06%, so the evacuation time and the expected evacuation distance were significantly improved. The experimental results and data analysis prove the effectiveness of the modification method and scheme of directional emergency evacuation signs in the experimental area. At the same time, a new optimization method and process of directional emergency evacuation signs layout is established.
