Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: the current traffic markings have a single color, basically white or yellow, and the planning process lacks overall consideration with the sign setting, so that the combined guiding function of the two cannot be fully utilized

Embodiment 1

[0017] Example 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 guide arrow is green, the straight guide arrow is yellow, the colored guide markings on the road surface are 45 cm long and 7 cm wide, and three colored guide markings on the road surface are set for each entrance lane, which are respectively set on the supports of traffic signs At the starting position of the forbidden lane line and the stop line, the color is drawn with reflective material. The roadside traffic signs are set on the sidewalk side, and the color indicator strips are marked under the Chinese characters indicating the direction on the sign board. Note.

[0018] The joint design method of colored traff...

Embodiment 2

[0020] Example 2: Combining Figure 1-Figure 3 , due to the continuous setting of traffic markings, they can complement each other with point-like traffic signs, that is, using colored markings to make up for the shortcoming 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.

[0021] The present invention includes the traffic sign leading distance D of the intersection entrance road s The calculation formula of the straight-going arrow setting g and the setting c of the straight-going bar on the sign, the sett...

Embodiment 3

[0048] 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):

[0049] ①Calculation of sign reading distance l

[0050] 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. The 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

[0051] Taking the driver information processing rate as 4bit / s, the reading time is 2.4183 / 4=0.61s;

[0052] From this we get t 1 =2.5×2×1.2+0.61=6.61s;

[0053] Taking the urban road travel speed as 60km / h, the sign recognition distance

[0054] ②Calculation of reaction distance j

[0055] Assuming that the judgment time is 3.5s, and the speed of the driver i...

Abstract

The invention belongs to the technical field of road traffic signs, and discloses an urban road intersection traffic sign line and a positioning method thereof to direct vehicles. The urban road intersection traffic sign line has the characteristic of being continuous, facilitates improvement of spatial cognitive psychology of divers, facilitates correction of wrong visual image and orientation concept of people, facilitates reduction of mental fatigue due to anxiety and confusion caused by path selection and judgment, and facilitates formation of longtime effective memory and judgment. According to the positioning method, only simple parameters need to be conveniently measured to determine the front distance of traffic signs, and further sign board color indicator bars and road colored guide lines can be arranged to lead the divers to reasonably park based on driving needs. Urban traffic management departments can erect and spray traffic sing lines with the best management effect according to the method. The colored sign lines are simple in principle, low in construction difficulty, high in speed, low in project investment, and is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of road traffic signs, in particular to a traffic sign line at an urban road intersection and a method for determining its position. Background technique [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. 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 ...
