摘要
地铁站内的应急逃生效率对于高密度城市的交通网络韧性至关重要,理解公众对站内标识引导系统的感知,进而合理布局应急标识位置,有助于在突发事件中快速引导并疏散人群。为此目的,在虚拟仿真环境中结合眼动追踪技术,构建地铁站模型并分别模拟水灾、火灾逃生情境,征集110位被试者开展眼动感知实验,收集并分析眼动追踪数据。结果显示,两种灾害情境中地铁站内不同空间位置的应急标识的感知存在显著差异:①火灾情境下,立体枢纽型位置的标识重要性更高,醒目性也较高;平面通道型位置的标识重要性更低,醒目性也较低。②水灾情境下,平面枢纽型位置的标识重要性更低,而标识布局较少的平面通道型位置,其标识醒目性更低。
The efficiency of emergency evacuation within metro stations is crucial to the resilience of transportation networks in high-density urban areas.Understanding the public’s perception of signage guidance systems and optimizing the spatial placement of emergency signs can facilitate the rapid guidance and evacuation of crowds during unexpected incidents.To this end,a metro station model is constructed in a virtual simulation environment,where eye-tracking technology is employed to simulate evacuation scenarios involving flooding and fire.A total of 110 participants were recruited to conduct eye-tracking perception experiments,and the resulting gaze data were collected and analyzed.The results reveal significant spatial differences in the perceived importance and visual saliency of emergency signs across the two disaster scenarios:①In the fire scenario,signage located at three-dimensional nodal spaces exhibites higher importance and greater saliency,while signage in planar corridor spaces showes both lower importance and lower saliency.②In the flood scenario,signs in planar hublike areas are perceived as less important,and those in corridor-type spaces with fewer signs are markedly less salient.
