Traffic signs

Hello everyone!

Today I will talk about the relation between the traffic signs form and geometry, because these have different geometrical forms. Between them, we can find triangles, squares, rectangles, circles... having each of them a different meaning. 

But there are specially two traffic signs, which possess a different form to the others and make them easy to recognize. These are the "ceda el paso" and "STOP" signs. Both signs are collected within the priority signs and are considered one of the most important and essential, therefore the need to recognize in a fast and simple way. 

Specifically,  the "STOP" sign, a few centuries ago in USA possessed a different way: it was in the form of square, small and white. Later, with the appearance of several more traffic signs, the need to modify this sign arose. It was when it was decided to use the octogonal form with its name placed in the center. 

But, why this form? The reason is that this form is easy to recognize independently of the climatic condition there is. 

In addition, it can be recognized from behind, being able to know to the perfection that those who must stop are the rest of drivers, that is to say, that you have priority. 

The same goes for the "ceda el paso" sign, as it is the only inverted triangle-shaped sign.
