为保障冰雪环境条件下的行车安全,研究弯道交通标志色彩对驾驶员的影响。通过分析标志信息的传递原理及色彩的心理效应特性,建立驾驶员心理效应量化计算模型。设计冰雪弯道标志铺设方案,分别对冰雪路面和良好路面开展弯道标志试验。采用科恩d值,评价驾驶员色彩心理效应。试验结果表明:良好路面科恩d值为0.2~0.5;冰雪路面颜色产生的驾驶员的心理效应差异较大,红色最强,绿色次之,蓝色最弱。对于各个检测点,良好路面条件下驾驶员各色彩的心理效应分布较为稳定,而冰雪路面时具有明显差异,心理效应分布较为分散。合理设置冰雪环境弯道标志色彩,能够有效提高驾驶员的心理效应。
In order to ensure driving safety under the conditions of ice and snow, the impact of the traffic sign color on the driver is studied. By analyzing the transmission principle of sign information and the psychological characteristics of color, a quantitative calculation model of driver psychological effect is established. Design ice and snow road marking pavement plan, respectively, on the ice and snow pavement and good road curve test signs. Using Cohen d value, evaluate driver color psychology effect. The test results show that the Cohen d value of good pavement is 0.2-0.5. The driver's psychological effects caused by the pavement color of ice and snow are quite different, the red is strongest, the green is the second, and the blue is the weakest. For each test point, the distribution of psychological effects of each color of driver under good road conditions is relatively stable. However, there are obvious differences in the ice and snow pavement, and the distribution of psychological effects is relatively dispersed. Reasonable setting ice and snow environment curve logo colors, can effectively improve the driver's psychological effects.
