What are the classifications of traffic signs?

When you walk on the road, as long as you pay a little attention, you will see various signs and signs on both sides of the road, in the sky or on the road. People liken these signs and signs to silent traffic police. The traffic management department calls these traffic signs or road traffic signs.

Traffic signs and pavement markings are traffic management measures that use words, symbols, lines or colors to guide, warn, regulate or instruct traffic. It provides pedestrians and drivers with accurate road traffic information, making road traffic smooth, safe, low-pollution and energy-saving. According to their different functions, traffic signs and road markings are generally divided into four types: guidance, warning, regulation and instruction.

The guidance category mainly provides people with various directional information, which is of an inquiry nature. Such as road name, place names and facilities along the road, distance, route, direction, etc. With such a sign system, even people who have never been to this city do not need to delay asking for directions, and can even reach their destination directly without taking detours. Some cities also use vivid images to guide pedestrians and vehicles. For example, on both sides of the streets in German cities, road signs with cameras are hung: indicating that tourist attractions can be reached in this direction. Or there are road signs with ball racks, rings and female divers jumping from the springboard into the pool to tell people that there is a gymnasium or stadium ahead. France has "smiling road signs" in the bustling areas of cities: a smiling young girl tells pedestrians that there are entertainment venues ahead.

Warnings mainly provide people, especially drivers, with information about dangers or information that should be paid attention to on or along the road. Such as the existence and shape of intersections, road bends and the direction in which they bend, road narrowing and lane reduction, slippery roads, steep slopes, construction, etc., to arouse people's vigilance. Some city bus stations have anti-theft "warning signs": a thief carrying stolen goods is running away in a hurry. He holds a master key in his hand with the words "Beware of Thieves" on it. In some cities, there are paintings of a quiet nurse placing the tip of her index finger on her lips, or paintings of a "sleeping baby girl" to remind people that there are hospitals and nurseries nearby, so please drive slowly and don't honk the horn.

The regulatory category is set by the transportation department according to regulations and represents traffic prohibitions or restrictions. The difference between it and the first two types of functions is that the regulatory type has the function of law, and violators must be treated as violations. For example, use signs to indicate: no vehicles carrying dangerous goods, no trucks, tractors, no parking, no sirens, no bicycles, no pedestrians, etc. In order to protect children's traffic safety, Japanese cities have set up safety flags for them to cross the road. All school-age children wear yellow hats when crossing the road and are escorted by women holding yellow flags. The ground in the alley where there are many school children is painted green, with large light yellow characters written on it: School Zone. There are large signs posted everywhere on the surrounding walls, warning drivers to be aware of children suddenly rushing out.

Indicators indicate permitted traffic behaviors to people, or remind people of things to pay attention to. For example, parking, priority roads, dedicated roads and safety zone signs can be used, as well as lane lines, center lines, parking lines, crosswalks and other signs. Among the endless flow of cars in Japan, you will find that some cars have a yellow mark on the front and rear. If it is illuminated by car lights at night, the yellow mark will reflect light. This yellow mark indicates that the driver of the vehicle has been licensed for less than one year and requires vehicles behind him not to get too close and oncoming vehicles to slow down to prevent accidents. However, if this yellow mark is not removed after the expiration date, even if it is one day overdue, you will be severely fined if discovered by the police.

Recently, some modern road signs have come out one after another. The British placed "flashing road signs" on the roads. It is a special infrared device that records car traffic and monitors the distance between moving cars. If the distance between two vehicles is less than the prescribed standard, the road sign will illuminate and display the words "too close" to warn the illegal driver. On highways in many countries, there is not a single traffic policeman standing in the middle of the road during the entire journey. Everything is controlled by computers. On the tall electronic display board, various texts are constantly changing, reminding people to pay attention to the distance, telling people where they are going to be, how many kilometers ahead a traffic accident occurred, how long the traffic jam will last, etc., making it clear to people. In order to make the appropriate choice as soon as possible.
