1. building name signs and speed

People in different moving speed, vision is to change, the faster the speed, the more the visual acuity in the field of vision to see objects. How much specific vision decline must be verified by experiments, if the development of standards must be carried out a large number of experiments, investigations and verification.

2, building name signs shape

The shape of building name signs, especially the shape of traffic building name signs, must meet national standards or international standards, and in the case of no standard specifications, pay attention to the principle of easy to identify, not identical (preferably unique).

3. Size of building name signs

According to the human factor experiment, the larger the building name signs under the same visual distance, the shorter the recognition time of people, on the contrary, the longer the recognition time. The size setting depends on how long we expect to complete the recognition. Of course, the premise is that the size of the building name signs can be seen at the farthest point of the set visual distance. On expressways, vehicles travel at a fast speed, and drivers must complete identification in a very short time, so the building name signs on expressways are much larger than the size of building name signs on ordinary urban roads.

4. building name signs and text symbols

There are rules for how many words, symbols or patterns are written on a sign, first of all, the size must be visible, and then it can be read in the expected recognition time.

5. building name signs and color

Whether the building name signs are clear or not has a great relationship with the color used. If the building name signs of the same size are seen from the same visual distance, the underlying color of the sign board and the color of the text symbols on it are different, whether they can be seen and how long it takes to identify them are very different. In general, the higher the warning level, the brighter the color used, and the greater the color contrast.
