What are the classifications of traffic signs?
Traffic signs and road markings are traffic management measures that use words, symbols, lines or colors to guide, warn, standardize or indicate traffic. It provides accurate road traffic information for pedestrians and drivers, 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 categories: guidance, warning, adjustment and indication.
Orientation course is mainly to provide people with all kinds of orientation information, with the nature of inquiry. Such as road name, place names and facilities along the way, distance, route and direction, etc. With such a sign system, even people who have never been to this city can reach their destination directly without having to delay time by asking for directions. Some cities also use vivid pictures to guide pedestrians and vehicles. For example, road signs painted by cameras are hung on both sides of the streets of German cities, indicating that tourist attractions can be reached along this direction. Or draw signposts with ball racks, rings and female divers who jumped into diving pool from the springboard to tell people that there is a gymnasium or stadium ahead. France has a "smiling signpost" in the downtown area of the city: a cheerful young girl is telling pedestrians that there are entertainment places ahead.
Warning categories mainly provide people (especially drivers) with information about dangers or preventive measures on or along roads. Such as the existence and shape of intersections, the direction of road bending, road narrowing and lane reduction, road slippage, steep slopes, construction, etc., in order to arouse people's vigilance. In some city bus stations, anti-theft "warning signs" are hung: a thief carrying stolen goods is fleeing hastily, and he is holding a master key that says "beware of thieves". In some cities, there are pictures of quiet nurses sticking their fingertips to their lips, or pictures of "sleeping baby girls", reminding nearby hospitals and nurseries to walk slowly and not honk their horns.
Laws and regulations are formulated by the transportation department according to laws and regulations, indicating that traffic is prohibited or restricted. The difference between it and the first two functions is that the prescribed category has the function of law, and violators should be dealt with according to the law. For example, signs indicate that vehicles carrying dangerous goods are forbidden to pass, trucks and tractors are forbidden to pass, parking is forbidden, honking is forbidden, bicycles are forbidden to pass, pedestrians are forbidden to pass, and so on. In order to protect children's traffic safety, Japanese cities set up safety flags for them to cross the road. All school-age children wear yellow hats when crossing the street and are escorted by women holding yellow flags. In the alley where children come and go, the ground is painted green and written in big yellow letters: school district. Large signs are posted on the surrounding walls to remind drivers that children will suddenly rush out.
Instructions are to point out the allowed traffic behaviors or to remind people of matters. For example, signs of parking, priority roads, dedicated roads and safe areas, as well as lane lines, center lines, parking lines, crosswalk lines, etc. In the endless stream of cars in Japan, you will find yellow signs on the front and back of some cars. If the lights go out at night, the yellow sign will reflect light. This yellow sign means that the driver of this car has not obtained the license for one year, and asks the vehicles behind him not to get too close, and the oncoming vehicles should slow down to prevent accidents. However, if this yellow label is overdue, even if it is overdue for one day, it will be severely punished by the police.
Recently, some modern road signs have come out one after another. The British set up "flashing road signs" on the road. It is a special infrared device, which can record the traffic flow and monitor the driving distance. If the distance between the two cars is less than the specified standard, the road sign will flash and display the words "too close" to warn the illegal drivers. In many countries, there is no traffic police standing in the middle of the road, and everything is controlled by computers. On the high electronic display board, all kinds of words are constantly changing, reminding people to pay attention to the distance, telling people where to go ahead, how many kilometers ahead of traffic accidents, and how long the traffic jam will last, so that people can see at a glance and make corresponding choices as soon as possible.
