(1) warning sign: a sign warning vehicles and pedestrians to pay attention to dangerous places.
(2) Prohibition signs: signs that prohibit or restrict the traffic behavior of vehicles and pedestrians.
(3) Indicating signs: signs indicating the movement of vehicles and pedestrians.
(4) Guiding signs: signs indicating the direction, position and distance of roads.
(5) signs of tourist areas: signs that provide directions and distances of tourist attractions.
(6) Road construction safety signs: signs announcing the traffic in the road construction area.
(7) Auxiliary signs: signs attached to the main signs to help explain the purpose. ?
The prescribed road traffic markings are divided into three categories:?
(1) Indicating markings: markings indicating the roadway, driving direction, road edges, sidewalks and other facilities.
(2) Prohibitive markings: markings that indicate the special regulations such as compliance, prohibition and restriction of road traffic, and that drivers and pedestrians of vehicles need to strictly abide by them.
(3) Warning markings: markings that urge drivers and pedestrians to understand the special conditions on the road, be vigilant and make emergency preparations.
Question 2: How many kinds of traffic signs are known in China but unknown in the world? They should be similar:
1) warning sign: a sign warning vehicles and pedestrians to pay attention to road traffic.
2) No sign: a sign that prohibits or restricts the traffic behavior of vehicles and pedestrians.
3) Indicating signs: signs indicating that vehicles and pedestrians should follow.
4) Guiding signs: signs that convey information about road direction, location and distance.
5) signs of tourist areas: signs providing directions and distances of tourist attractions.
6) Road construction safety signs: signs informing the road construction area and traffic blocking and bypassing.
7) Auxiliary explanatory signs attached to the main signs.
Question 3: What are the classifications of road traffic signs? 1) Traffic signs are divided into main signs and auxiliary signs according to their functions. The main signs include warning signs, prohibition signs, indicating signs, guiding signs, tourist area signs, work area signs and notification signs. Auxiliary signs are signs attached to the main signs to help explain. Auxiliary signs cannot be used alone. 2) Traffic signs are classified according to their display positions, which are divided into roadside and roadway. Support forms include single column, double column, single cantilever, double cantilever, portal frame and attached type. 3) According to the optical characteristics, traffic signs can be divided into three types: reflective type, illuminating type and luminous type, among which the illuminating type is divided into internal lighting and external lighting. 4) Traffic signs are divided into static signs and variable information signs according to the display mode of layout content. Variable information sign is a sign that changes the display content according to the change of traffic, road and climate. Generally, it can be used to display speed control, lane control, road conditions, meteorological conditions, etc. The variable information sign shall not display information unrelated to traffic.
Question 4: How many kinds of traffic warning signs are there? Modern road traffic signs in China are divided into two categories: main signs and auxiliary signs *** 100.
1, the main sign of road traffic
The main signs of road traffic can be divided into four types according to their meanings: warning signs, prohibition signs, indicating signs and guiding signs.
(1) Road traffic warning signs. There are 23 kinds of road traffic warning signs, which warn vehicles and pedestrians to pay attention to dangerous places. Their shape is an equilateral triangle with upward vertex angle, and their color is black pattern with yellow background and black edge.
(2) Road traffic ban signs. There are 35 kinds of prohibition signs, which are signs that prohibit or restrict the traffic behavior of vehicles and pedestrians. Its shape is divided into circle and equilateral triangle with downward vertex angle, and the colors are white background, red circle, red stripe, black pattern and patterned layering, except for individual signs.
(3) Road traffic signs. There are *** 17 kinds of signs to indicate the movement of vehicles and pedestrians. Its shape is divided into circle, rectangle and square, and the color is white on a blue background.
(4) Road traffic signs. There are ***20 kinds of road signs, which convey information such as road direction, location and distance. Its shape is rectangular and square except for the position identification mark; Its color, except milestone, 100m pile and expressway boundary pillar, is generally blue and white on the highway, and green and white on expressway.
2. Road traffic auxiliary signs
There are five kinds of auxiliary road traffic signs, which are attached to the main signs and play an auxiliary role. This kind of road traffic sign cannot be set and used separately. Road traffic auxiliary signs can be divided into several types according to their uses, such as signs indicating time, vehicle type, regional distance, warning and prohibition reasons, and combined road traffic auxiliary signs. Its shape is rectangular, and its color is white background, black characters and black border. In addition, there are variable traffic information signs, which display some information in time according to the conditions detected by the road (such as road occupation, congestion, changes in flow and direction, climate conditions, etc.) and convey it to vehicle drivers and pedestrians. ).
3. Geometry and significance of road traffic safety signs.
Whether the visibility and display degree of road traffic safety signs are good or not has an important relationship with the shape of traffic signs. In the case of the same area, the order of good effect and easy recognition is: triangle, diamond, square, regular pentagon, regular hexagon, circle, regular octagon and so on.
The provisions on geometric figures in the draft standard of international "Safety Colors and Safety Signs" are: regular triangles indicate warnings; Circles indicate prohibitions and restrictions; Square and rectangle represent the tip; A circular pattern with diagonal lines also indicates prohibition. The international standard of modern traffic sign geometry in China is basically consistent with the national standard of safety signs.
(1) triangle. Height display, regardless of lighting conditions, is more eye-catching than other shapes. In China, the regular triangle is used as the geometric shape of warning signs, and the inverted triangle is used for "stopping and giving way" and "walking slowly".
(2) circular. The circular display has high visibility and is convenient for arranging characters. In China, a circle is a geometric shape used to prohibit and indicate two kinds of signs.
(3) square. Include rectangles and squares, and their visibility is used to guide the geometry of traffic signs.
Question 5: * * * What is a traffic sign? 3.3. 1 Traffic signs are classified according to their functions, which are divided into two categories: main signs and auxiliary signs. A) main sign 1) warning sign: a sign warning vehicles and pedestrians to pay attention to dangerous places. 2) No sign: a sign that prohibits or restricts the traffic behavior of vehicles and pedestrians. 3) Command signs: signs that vehicles and pedestrians must follow. 4) Guiding signs: signs that convey information about road direction, location and distance. 5) Tourist area identification: provide the identification of the direction and distance of tourist attractions. 6) Road operation area sign: a sign informing the passage of the road operation area. 7) Signs: Signs informing road facilities, off-road facilities and safe driving information. B) Auxiliary signs are attached to the main signs for auxiliary explanation. 3.3.2 According to the supporting forms, signs can be divided into single column type, double column type, single cantilever type, double cantilever type, portal type and attached type. 3.3.3 According to the classification of optical characteristics, signs can be divided into retroreflection, illumination and luminescence; Among them, lighting is divided into internal lighting and external lighting. 3.3.4 According to the display mode of layout content, signs can be divided into static signs and variable information signs. 3.3.5 According to the classification of setting years, signs can be divided into permanent signs and temporary signs. 3.3.6 Legal effect a) Prohibition signs and indication signs have the same legal effect; B) Variable information signs and temporary signs are displayed as prohibited signs and indicative signs, which have the same legal effect as the corresponding static signs and permanent signs; C) The prohibition and indication signs are set on the white floor without borders and have corresponding legal effect; D) The prohibition sign is used on the guide sign, which only means providing relevant prohibition information and has no corresponding legal effect. 3.4 Color 3.4. 1 Basic meaning of traffic sign color a) Red: it means prohibition, stop and danger, and is used for the border, background color and diagonal line of prohibition signs, as well as the background color of cross, diagonal line symbol and warning linear guidance target; B) Yellow: warning, which is used as the background color of warning signs; C) Blue: indicates instruction and compliance, and is used as the background color of indication signs; Driving instructions indicating place names, routes, directions, etc. Used as the background color of general road signs; D) Green: driving instructions indicating place names, routes, directions, etc. , used as the background color of expressway road signs;
Question 6: What kinds of traffic signs can be divided into? Road traffic signs are divided into main signs and auxiliary signs. The main constellations can be subdivided into the following categories: 1. Warning sign: a sign warning vehicles and pedestrians to pay attention to dangerous places. 2. Prohibition signs: signs that prohibit or restrict the traffic behavior of vehicles and pedestrians. 3. Indicating signs: signs indicating the movement of vehicles and pedestrians. 4. Guiding signs: signs that convey information about road direction, location and distance. 5. signs of tourist areas: signs that provide the direction and distance of tourist attractions. 6. Road construction safety sign: a sign announcing the passage of the road construction area. Auxiliary sign: a sign attached to the main sign to help explain. The outer edge of the road traffic sign frame has a background color. The provisions of background color are: yellow warning sign, white prohibition sign, blue indication sign, green guiding sign of expressway and urban expressway, and blue guiding sign of other roads.

Question 7: The main types of traffic signs. There are four ways to support traffic signs: column, cantilever, portal and attached. The support mode of traffic signs should be comprehensively determined according to traffic volume, vehicle composition, number of lanes, distribution of structures along the line, wind load, roadside conditions and other factors. (1) Warning, prohibition, indicating signs and small guiding signs should be supported by single column, and medium and large guiding signs can be supported by double columns or multiple columns. (2) When the following conditions are met, cantilever or gantry support can be used as needed (cantilever support is appropriate when there are few layout contents): ① When the traffic volume reaches or approaches the design capacity; ② When the interchange design is very complicated; ③ When there are three or more lanes in one direction; ④ Interchange spacing is small; ⑤ When the exit is multi-lane; ⑥ When the proportion of large vehicles is large; ⑦ When crossing multiple interchanges, set the position consistency to keep the sign information; When the roadside installation space is insufficient or blocked; Pet-name ruby when connecting two hubs between expressway; When the exit ramp is the left exit, pay attention; 8 intersection signs or exit warning signs at the starting point of deceleration lane of interchange. (3) When overpasses and other structures are set along the highway, and high retaining walls and light poles are set on the roadside, traffic signs can be supported by attachment on the premise of meeting the requirements of highway building clearance.
Question 8: How many kinds of traffic signs are there? What do they do? Highway traffic signs are facilities that use graphic symbols and words to convey specific information, which are used to manage traffic and indicate driving directions to ensure smooth roads and safe driving. It is applicable to expressways, urban roads and all special highways, and has the nature of law, which vehicles and pedestrians must abide by.
Highway traffic signs are divided into two categories: main signs and auxiliary signs. There are mainly four kinds of signs: warning signs, prohibition signs, indicating signs and guiding signs.
The shape, color, size, pattern type and location of road signs shall conform to the provisions of the current Road Traffic Signs and Marking (GB5768).
All traffic signs should be correct, accurate, complete, eye-catching and beautiful.
The role of various signs:
(1) Warning signs are signs that warn vehicles and pedestrians to pay attention to dangerous places;
(2) Prohibition signs are signs that prohibit or restrict the traffic behavior of vehicles and pedestrians;
(3) Indicating signs are signs indicating the movement of vehicles and pedestrians;
(4) Guiding signs are signs that convey information such as the direction, location and distance of roads.
The auxiliary sign is attached to the main sign and plays an auxiliary role, which is divided into time, vehicle type, area or distance, warning, prohibition reasons and other types.
Provisions on colors and shapes of various signs:
(1) The color of the warning sign is a black pattern with a yellow background and black edges, and the shape is an equilateral triangle with the vertex facing upwards.
(2) The color of the prohibition sign is white background, red circle, red bar and black pattern, and the pattern is embossed. Among them, the sign of lifting the prohibition of overtaking and speed limit is a black bar with a black circle on a white background and a black pattern. The shape is round, and the giving way sign is an equilateral triangle with the vertex down.
(3) The color of indicator is blue background and white pattern. Shapes are round, rectangular and square.
(4) Except for milestones, 100-meter piles and highway jiepai, the color of road signs is generally blue and white. Except for the location identification signs, the shapes are all rectangular and square.
Milestones, 100-meter piles and road boundary piles are all guiding signs. When the milestone is located on the national highway, the colors are white and red; When set on the dart, the color is white and blue; When it is located on the county highway, the color is white and black. Regardless of the nature of the road, the color of expressway boundary markers is white and black.
The auxiliary sign is a sign attached to the main sign and plays an auxiliary role. Points indicate time, vehicle type, area or distance, warning, reasons for prohibition, etc.
Location of various flag settings:
The location of warning signs is related to the calculation speed of expressway. In rural mountainous areas, highways should generally be located 20 ~ 50 meters away from dangerous places.
No parking signs should generally be set where restrictions or prohibitions are needed. In addition to no parking signs, the starting and ending points of restricted or prohibited sections and both ends of the bridge should be set in pairs.
Indicating signs are mostly used in urban roads and high-grade highways, and are rarely used in general highways.
Directional signs are commonly used signs in expressway, such as place names, boundaries, directions, milestones, 100m stakes and expressway boundary stakes. Place name signs are located on the edge of the town; The nail landmark is located at the boundary between the administrative division and the trusteeship section; Direction signs are set 30 ~ 50 meters away from the intersection.
Setting methods and relevant regulations of traffic signs:
There are four ways to support traffic signs in expressway: (1) columns (including single column and double column); (2) cantilever type; (3) portal type; (4) Attached type.
Relevant provisions on the setting of highway signs:
The inner edge of column sign shall not be less than 25 cm from the road surface (or shoulder), and the height of the lower edge of the sign from the road surface shall be 180 ~ 250 cm.
The height between the lower edge of the cantilever sign and the road surface, the clear height of the first and second grade roads is 5 meters, and the clear height of the third and fourth grade roads is 4.5 meters. The distance between the inner edge of the column and the road surface (or shoulder) shall not be less than 25cm.
The provisions for setting the entrance sign are the same as those for the cantilever sign.
The setting rules of attached signs are the same as those of column signs.
Question 9: How many kinds of traffic signs are there? main mark
The main signs can be divided into four types.
(1) indicator; Usually round and rectangular, with white patterns on a blue background. Used to instruct vehicles and pedestrians to drive in the specified direction and place. Such as going straight, turning left, turning right, stopping, bypassing, etc. ② Warning signs: generally equilateral triangle (or diamond), yellow (white) background with black (red) edge, and black (or dark blue) pattern. It is used to warn drivers to pay attention to the dangers of the road ahead and the measures that must be taken. For example, predict intersections, road turns, railway crossings, slippery sections, possible rockfall sections, uneven roads, combined traffic, etc. ③ Prohibition signs: generally round, with white background and red edges, red diagonal lines and black patterns. It is a sign that vehicles are prohibited or appropriately restricted according to the situation of streets, highways and traffic flow. Such as no traffic, no parking, speed limit, weight limit, width limit, etc. ④ Guiding signs: generally rectangular, with white characters on blue (green) background. Used to indicate the boundaries between towns and villages, the direction and distance of destinations, the entrances and exits of expressway, service areas and places of interest. And provide various directions along the way. Such as national highway numbers, milestones, 100-meter piles, boundary markers, signs and nameplates, and signs of entrances and exits, gas stations, repair stations and parking lots in expressway. The auxiliary sign is attached to the main sign and plays an auxiliary role. It can be divided into four categories: vehicle type, time, interval range and distance. Auxiliary signs cannot be set separately.
Auxiliary sign
Signs attached to the main signs to help explain are divided into time, vehicle type, area or distance, warning, reasons for prohibition, etc.
Question 10: When was the earliest traffic sign made in China? * *1934 65438+February 2 1 How many kinds are there? At that time, the Ministry of Interior of the State promulgated the first land traffic management rules in China history, which included 27 road traffic signs in three categories, including the no sign 10. During the period of 1935, Jiangsu, Zhejiang, Anhui, Beijing and Shanghai jointly issued the Road Traffic Signs Map, which belongs to the early road traffic signs and marking standards in China.
