Basic Signs - Fruitiger

The Square -

Due to it's well known shape and outline, the square offers a form of structure, protection and stability. The Quadrilateral is somewhat comforting and easily established as a simple shape by all audience members.

However once the square is rotated to stand on it's point "The view of this sign is disquieting, and its position on its point indicates a certain intention, which is why this form is used as the ideal background for traffic signs, especially in the United States.” (Fruitiger, 1989, p. 43)

The Triangle - 

 

Placing the triangle vertically onto its apex create a form of direction. Giving it a form of character and movement when placed either vertically or horizontally, the triangle is successfully used for signs that indicates directions left and right. 

However a triangle with a horizontal side becomes successful to use for signals due to its symmetry. This is further explained as the composition of the triangle echoes a form of stability and permeance, "It is also the symbol for the expression “wait,” rather like a mountain, whose only active function is to suffer erosion.” (Fruitiger, 1989, p. 44)

The Circle - 

Due to the lack of straight line, the curved line shape has less of a spontaneous relationship with modern humans. Feelings are evoked strongly with the use of a circle compared to any other signs. The viewer, depending on their character tend to place themselves either inside or outside of the circle. Being inside the circle creates a rather authoritative or hostile, possibly being a reason why the circle is used to command or give orders to the audience.
