【摘要】：为了提高冰雪公路弯道行车安全,研究冰雪环境中驾驶员对不同线形诱导标志的视认效果,通过分析驾驶员色彩视觉效应,采用3ds Max软件建立了冰雪公路弯道仿真模型。基于E-prime软件分别进行了不同速度下反应时间的色彩视认心理物理试验,根据试验结果采用回归分析法确定了行驶速度与视认距离之间的定量关系。对比结果表明:不同的色彩对冰雪环境中视认距离表现出较大差异;蓝色和红色标志拥有最佳视认效果,表现为在20~50 km/h速度中,视认距离介于33 m和41 m之间,并拥有良好的稳定性,其中蓝色标志的视认效果略优于红色标志;绿色标志视认距离稳定性较差,黄色标志视认距离整体最低,二者均不利于行车安全性。
[Abstract]:In order to improve the traffic safety of ice and snow highway bends and to study the recognition effect of different linear induced signs in ice and snow environment, a simulation model of ice and snow highway curve was established by analyzing the color vision effect of drivers and using 3ds Max software. Based on E-prime software, the psycho-physical experiments of color recognition at different speeds were carried out, and the quantitative relationship between driving speed and visual recognition distance was determined by regression analysis based on the test results. The results show that different colors have great difference on the visual recognition distance in snow and ice environment, and the blue and red signs have the best visual recognition effect, which shows that the apparent recognition distance is between 33 m and 41 m at the speed of 20 ~ 50 km/h. And has good stability, among which the blue sign is a little better than the red sign, the green sign is less stable, the yellow mark is the lowest, both of them are not conducive to the safety of driving.
