1. The road not only have guardrail and traffic signs. China highway engineering technical standards; Mark is the important traffic management facilities. They divided into warning sign and directional signs, direction signs and shop sign. 。 Therefore, if the road there is no sign of this, if the driver on the road, don't get any information he becomes blind and chaos, the result can be imagined. Of course, the guide of modern traffic management should be accompanied by line and police officers. Traffic lights to guide way to monitor the entire transportation even under a series of management, to ensure that vehicles running fast, safe and orderly. Therefore, logo can be described as a silent language road, road safety is one of the protector. It is a kind of information symbol, is a kind of important traffic management facilities, and by the graphics, symbols, text, special information management of content and behavior rules. It can be erected on the road surface, placed in the middle of the highway subgrade or road on both sides with conspicuous position. It also made out of different colours and reflective material, can be in the daytime or night showed clear traffic information. In the long journey, guide your driving direction and location, tell you what to do and what not to do on the road, and if there is a sharp turn, steep slope, a crossroads, Bridges and tunnels. Where is incidence of accident. Where can be filled with oil, repair, cleaning and parking, and even can be used to eat, eat, live and travel, The highway is often referred to as service) 。 In short, it can make you safe travel smoothly. 2. The evolution of the two symbols. 1 material: sign including wood, synthetic resin plate and waterproof plywood. In order to save timber, also in order to achieve durable and beautiful, the multi-purpose metal material owing to the strong wind and bending, and easily stolen. They have also been developed into marks surfaces and composite materials. Plate made of aluminum alloy sheet metal materials extrusion patchwork, then by solid object size spliced into various floor surface by the regulation, and tags can be made of reflective material, coating and paint, ink, adhesive, transparent rubber sealing side, so the stability and security. Type 2. 2 the sign has two types: ( 1) It is fixed. A number represents a content and fixed in one place. It is called fixed. ( 2) Variable, it is mainly used for highway, such as variable speed signs, usually in the form of round, can according to different speed, such as 120, 100, 80, 60 ( Km/h) And so on. According to the need; hellip。 ; There is a content variable sign. Drawn up in advance in accordance with the contents of some commonly used like rain and fog weather, and driving will slow. Before construction, pay attention to safety driving. Welcome to the pool. Pool; Highway; Hello, welcome. hellip。 。 General fixed on a certain position or a frame overpass, by the central control room according to the content of the need to display in a timely manner. In the 300 - when driving at night Within 400 metres of can clearly see the sign. Variable sign board usually made by leds. Recently, fiber optic products. This character display brightness even, does not have a diode damage caused by the incomplete font phenomenon. It can easily adjust the brightness of the light to adapt to the different external environment, and the light source can be fully used to reduce energy consumption, Gs) 。 2. Three dimension size of the sign is the international standard. Highway sign and marking technology specification; Already there are specific requirements
