| 摘 要： | 随机选取了32名驾驶人,在黄昏时段获得了驾驶人对红色与绿色障碍物的判识距离,分析了环境照度对判识距离的影响规律,建立了不同深度距离下环境照度与判识距离的数学模型,定量比较了红色与绿色障碍物判识距离的差异。分析结果表明:随着外界环境照度的下降,判识距离逐渐增大;绿色与红色障碍物相比,距离判识差异显著,绿色障碍物判识距离大于红色障碍物判识距离;判识距离与照度的对数可用一元三次函数拟合,拟合度大于0.9。

| Abstract: | 32 drivers were selected randomly,their cognitive distances on red and green obstacles were gained at dusk,the influence rules of environment illuminations on cognitive distances were analyzed,some mathematics models between environment illuminations and cognitive distances were put forward under different depth distances,and the quantitative differences between red and green cognitive distances were compared.Analysis result shows that: the cognitive distance continuously increases with the decrease of envi... |
