Embodiment 1
[0031] Embodiment 1, combining Figure 1-Figure 3 , the present invention city road crossing colored traffic sign mark line, it is made up of pavement color guide mark line and roadside traffic sign board, it is characterized in that: road surface color guide mark line is arranged in the center of the carriageway, and the left turn guide arrow is Red, the right-turn guiding arrow is green, the straight-going guiding arrow is yellow, the colored guiding markings on the road surface are 45 cm long and 7 cm wide, and three colored guiding markings on the road surface are set for each entrance lane, which are respectively set at the traffic sign supports, It is forbidden to change the starting position of the lane line and the stop line, and the guide markings are drawn with reflective materials;
[0032] The roadside traffic signs are set on the sidewalk. The color of the arrows and Chinese characters indicating the direction on the roadside traffic signs is consistent with the c...
Embodiment 2
[0050] Example 2: Combining Figure 1-Figure 3 , due to the continuous setting of traffic markings, it can make up for the traffic signs set in dots, that is, the use of colored markings to make up for the shortcomings of discontinuous information on sign boards. The invention makes full use of the characteristics of color identification and strong sensitivity to draw colored traffic markings, reasonably determine the location of the traffic signs at the intersection, and spray-paint colored indicator strips on the sign boards to cooperate with the colored guiding markings on the ground Guidance path, that is, one color represents a travel path to guide motor vehicles at the intersection to stop in an orderly manner and move smoothly.
[0051] The present invention includes the traffic sign front distance D of the urban road intersection entrance road s The calculation formula of the straight direction arrow setting g, the setting of the straight direction bar on the signboar...
Embodiment 3
[0081] Example 3: Binding figure 1 , the front distance of the traffic sign D s The calculation method and the application case of the setting of the color guide marking line and the color indicator bar (indicated by image 3 example shown in):
[0082] ①Calculation of sign reading distance l
[0083] There are 12 Chinese characters on the signboard, and the total strokes exceed 15, then t 1 Take 2.5, w 1 Take 2, w 2 Take 1.2.12 Chinese characters are divided into 6 groups, the frequency of road is 1 / 3, the frequency of yellow, river and river is 1 / 6, and the frequency of long and pearl is 1 / 12, then
[0084] H ( s ) = - ( 1 3 log 2 1 3 + 3 × 1 6 log ...
