What's the difference between a traffic sign and a road sign?

Highway traffic signs: they are facilities that convey specific information with graphic symbols and characters, and are used to manage traffic and indicate driving directions, so as to ensure smooth and safe road driving. It is applicable to expressways, urban roads and all special highways, and it is legal in nature, and vehicles and pedestrians must abide by it.

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 of vehicles and pedestrians;

(3) Indicating signs are signs indicating the movement of vehicles and pedestrians;

(4) Guiding signs are signs that convey information about road direction, location and distance.

Auxiliary signs are signs attached to the main signs, which play an auxiliary role and are divided into time, vehicle type, area or distance, warning, prohibition reasons and other types.

Provisions on the colors and shapes of various signs:

(1) The color of the warning sign is yellow background, black edge and black pattern, and it is in the shape of an equilateral triangle with the vertex facing upwards.

(2) The colors of the prohibition sign are white background, red circle, red stripe and black pattern, and the pattern is pressed. 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 the indicator is blue background and white pattern. Shapes are round, rectangular and square.

(4) Except for milestones, 100-meter piles and highway jiepai, the colors of road signs are generally blue and white. Except for the location identification signs, the shapes are all rectangular and square.

Milestones, 100 meter piles and highway 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 colors are 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 road 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 expressways. 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 the no-stop sign, it should be set in pairs at the beginning and end of the restricted or prohibited road section and at both ends of the bridge.

Indicating signs are mostly used in urban roads and high-grade highways, and are rarely used in general highways.

Direction signs are usually used in ordinary roads, such as place names, boundaries, directions, milestones, 100-meter piles and road boundary markers. Place name signs are located on the edge of the town; Set demarcation marks in administrative divisions.

The boundary of the custody part; 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 expressway traffic signs: (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 distance between the inner edge of the post sign and the road surface (or shoulder) shall not be less than 25 cm, and the height between the lower edge of the sign and 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 highways is 5 meters, and the clear height of the third and fourth grade highways 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 rules for setting subsidiary signs are the same as those for column signs.
