摘要:
在介绍可见域概念的基础上,将导向标志可见域转化为偏移角和观察距离的关系,开展了不同偏移角下导向标志观察距离的测量实验,分别测定了两种导向标志类型(电光源型和磷光型)在两种环境照度水平(正常照明和无照明)下,9种偏移角(0°、10°、20°、30°、40°、50°、60°、70°和80°)所对应的观察距离。实验发现随着偏移角的增加,观察距离非线性的减少,导向标志的可见域为椭圆形,该椭圆的短轴是偏移角为0°时的观察距离,该项实验的开展为导向标志可见域的确定提供了基础数据。
Abstract:
Based on the introduction of the visibility catchment area of direction sign, the visibility catchment area of direction sign is quantified by the relationship of the bias angle with the observational distance. The experiments for measuring the observational distance of direction sign under different bias angles are conducted, and as a result the observational distance for two types of direction sign(electrically powered components and phosphorescent components)and two kinds of luminance level (normal lighting and no lighting) as well as nine bias angles (0°, 10°,20°、30°、40°、50°、60°、70°、80°) are measured. It is found that with the increasing of bias angle, the observational distance will be reduced nonlinearly. The visibility catchment area of direction sign is an ellipse, and the size of ellipse short axis is equal to the observational distance under the 0 degree bias angle. The experiments establish the fundamental dataset for the calibration of the visibility catchment area of direction sign.
