We can usually see that most of the traffic signs are white on blue background. Why is there only this style? In fact, this is an effect of traffic signs, mainly to make the shape, color, and pattern of traffic signs become the subconsciousness of drivers, and they will realize what they mean when they see it. The traffic sign manufacturer explains for you:
1. Shape
Marks with different appearances are different in their recognition process. Practice has shown that the easy-to-identify order of signs with the same shape and area is: triangle, square, regular pentagon, circle and regular octagon. It can be seen that the more edges and corners, the poorer visibility. Rectangular signs tend to be muddy with advertisements and other structures. Therefore, the road warning signs of the United Nations and many countries have adopted the three-yield shape. However, some countries (such as Guan Guo, Japan, Australia) have adopted the diamond shape as a warning sign. The reason is that the diamond shape has a larger area than the triangle, which enhances visibility.
2. Color
Most psychologists think that the color of traffic signs is a kind of stimulus to the vision that can inspire people to seek. The stimulus effect of different colors makes people have a different secret thought reaction, that is, the result of different visual recognition. So as to improve people's visual recognition ability, according to the research and comment, under the visual distance of 230M, the different colors The corresponding visually clear area can be seen from the above. Under the same visual rejection, the marking color is prominently yellow, followed by white, red, blue, green, black, etc.
3. Graphic symbols
The traffic sign symbol is the abbreviation of words, signs and patterns. Most of the road signs and traffic signs are represented by pictograms, which require conciseness and accuracy of text, intuitiveness and unification of symbols, and shared vividness and popularity of patterns. Symbols should be clear at a glance, not easy to misunderstand, and even foreigners can understand the meaning of symbols.
