Problems solved by technology

However, the current traffic markings have a single color, basically white or yellow, and the planning process lacks overall consideration with the sign setting, which makes it impossible to give full play to the joint guiding function of the two. In the setting, the mutual complementarity of the two functions is fully considered and the joint design is carried out

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 complement each other with point-like traffic signs, 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 layout position of traffic signs at intersections, 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-going arrow setting g, the setting of the straight-going bar on the signbo...

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] ① Calculation of sign recognition 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

Abstract

The invention aims to provide a method for the joint design of colorized traffic sign and marked lines at an intersection of an urban road, which can determine the preposition distance of a traffic sign to further set color indication bars of mark plates and road surface colorized guiding marked lines by only measuring simple parameters. The colorized traffic sign marked lines consist of the roadsurface colorized guiding marked lines and roadside traffic sign mark plates, wherein the road surface marked lines are arranged in the middle of a lane, a left-turning guiding arrow is red, a right-turning guiding arrow is green, a straight-moving guiding arrow is yellow, and the guiding marked lines are drawn by using a reflecting material. The roadside traffic sign mark plates are arranged on one side of a sidewalk, the colors of arrows and Chinese characters indicating directions are consistent with that of the guiding arrows of the road surface marked lines, the colors of Chinese character indication bars indicating directions are consistent with that of the guiding arrows of the road surface colorized guiding marked lines, and the indication bars are drawn by using the reflecting material. The colorized marked lines have the advantages of simple principle, low construction difficulty, high speed, less construction investment, and advantageous popularization and application.

Description

(1) Technical field [0001] The invention relates to traffic science, in particular to a joint design method of colored traffic signs and markings at urban road intersections. (2) Background technology [0002] Road traffic signs use graphic symbols, colors and words to convey specific information to traffic participants. Road markings are mainly used to induce, divert, prompt or restrict the driving of vehicles, so as to ensure the normal driving of vehicles on the road and avoid traffic accidents. happened. [0003] Whether the location of the traffic sign is reasonable or not will be related to the function of the sign. Since the driver has a certain time limit for the memory of the sign information, if the distance ahead of the traffic sign is too long, the driver has not reached the moment when the driving behavior needs to be changed for a long time, then the memory of the sign information in their brains will be reduced. If the distance is too short, the driver does ...
