研究目的: 疏散照明是地铁安全照明的重要组成部分,对地铁的运营安全具有重要影响,作为地铁疏散措施中的重要环节,疏散照明对提高疏散效率、保证疏散安全具有重要影响。本文以乘客视觉感知度为主要评价指标,利用眼动实验方法对传统静态照明标识与动态照明标识对乘客视觉感知度的影响进行研究。
研究结论: (1)乘客对动态照明标识的视觉感知度远高于传统静态照明标识;(2)不同变化形式、不同变化周期的动态照明对视觉感知度提升幅度不同,点追逐式动态照明对乘客视觉感知度的提升最大,且变化周期为3 s的点追逐式动态照明的视觉感知度最高;(3)本研究结论可为地铁安全照明设计提供参考。
Abstract
Research purposes: Evacuation lighting is an important part of subway safety lighting,which has an important impact on subway safety. As an essential step in subway evacuation measures, evacuation lighting significantly improves evacuation efficiency and ensures evacuation safety. In this paper, the visual perception of passengers was adopted as the main index, and the effects of static and dynamic lighting signs on visual perception of passengers were studied individually based on eye movement experiment.
Research conclusions: (1) The passengers' visual perception of dynamic light is higher than that of traditional evacuation lighting signs. (2) Dynamic lighting with different change forms and change periods shows different degrees of improvement in visual perception: point-chasing dynamic lighting has the most remarkable improvement in passenger visual perception, and point-chasing dynamic lighting with a change period of 3 seconds has the highest visual perception,which is more effective on improving evacuation efficiency and decreasing evacuation time. (3)The research results could provide a reference for the design of subway safety lighting.
