Geometry Stars Solar Traffic sign of its implications

The degree of visibility of traffic signs and displays are in good shape there is an important relationship with a traffic sign . In the case of the same size shape , effective and easy to identify the order is: triangle, diamond , square, pentagon , hexagon , round, octagonal , etc. .
The draft international standard " Safety colors and safety signs " in the provisions concerning the geometry is : triangle indicates a warning : Round said prohibitions and restrictions ; squares , rectangles represent tips ; circular pattern with a slash , also expressed prohibited. Traffic signs of modern geometry international standards and national "safety mark " provisions of the standard is basically the same .
⑴ triangle. High degree of display , whether good or bad lighting conditions , than other shapes compelling. China's use of the Road traffic signs of an equilateral triangle geometry , in the " make way for parking " and " slow to make way for " used inverted triangle .
⑵ round . A high degree of circular display , visual large, easy to arrange text, China will ban and instructions for round two signs geometry.
⑶ square . Including rectangles and squares , its visibility , traffic signs for guiding geometry .
