摘要
长时间高速驾驶容易造成驾驶员视觉和神经的双重疲劳和速度适应性提高,使得驾驶员对速度信息的获取和处理速度下降,造成驾驶员出现无意识超速行为.为此,文中将法契纳效应成色规律、人眼的辨色机理和高速情况下的视觉特性、道路的实际环境结合,设计一种施画在高速公路护栏上的矩形图案.在行车速度达到限制值时,驾驶员即可发现两旁的护栏出现彩色,从而在行车过程中实时意识到当前超速行驶状态.
Prolonged high-speed driving easily lead to visual fatigue,nervous fatigue and high-speed adaptation′s raising,which makes the drivers′unconscious speeding.This paper combines coloring law of Fechner Effect,the mechanism of color vision of the human eye and the visual characteristics of the high-speed with the physical environment of the road to design a special rectangular pattern painted on the highway guardrail.When the driving speed limit is reached,colors can be shown to the drivers on the guardrail and drivers will realize the speeding state.
