Abstract: The following constitution is employed for enhancing the visual recognition of a road traffic sign by presenting a road traffic sign composed of a solid pattern having shades as visual image. A marking pattern divided into plural sections is tightly formed on the road, and the adjacent sections are mutually different in lightness, so that, in the road traffic sign of the invention, a solid figure is recognized as the visual image of the marking pattern. Herein, the adjacent sections have a lightness difference of 1 or more in Munsell value, and the lightness of each section is selected at lightness in two to four stages set at mutually different Munsell values. Moreover, when the adjacent sections are colored in hues mutually different in lightness, a more solid visual image will be obtained due to the difference in hue among the sections.
