road traffic sign
Road traffic signs include warning signs, prohibition signs, indication signs, road signs, tourist area signs, road construction safety signs, and auxiliary signs. The purpose of setting up traffic signs is to provide accurate information to road passers-by to ensure safe and smooth traffic flow. Highways have high speeds, more lanes, and sign sizes that are much larger than those on general roads.
road markings
Pavement markings include prohibited markings, instruction markings, and warning markings. They are traffic control facilities that are directly sprayed with paint or prefabricated concrete blocks on the road to form lines and symbols, and are coordinated with road signs. There are many types of road markings, such as the center line of the driving lane, the vertical marking of the parking line, and the marking of the curb. Markings include continuous lines, discontinuous lines, arrow lines, etc., mostly white or yellow paint.
safety fence
The safety barrier on the highway should not only prevent the vehicle from going out of the way, prevent the vehicle from crossing the median strip and enter the opposite lane; at the same time, it should also induce the driver's sight.
isolation barrier
The isolation barrier is one of the infrastructures of the expressway, which enables the complete closure of the expressway and prevents people and animals from entering the expressway. It can effectively eliminate lateral interference, avoid the resulting traffic delays or traffic accidents, and ensure the full play of expressway benefits. According to the different materials used, the isolation fence can be divided into several categories: metal mesh, expanded metal mesh, barbed wire and evergreen hedge.
Road lighting
Road lighting is mainly to ensure the safety and smooth flow of traffic at night, and is roughly divided into continuous lighting, local lighting and tunnel lighting. Lighting conditions have a great impact on road traffic safety. Line-of-sight guidance signs are generally set along both sides of the lane, with the purpose of clearly indicating the road alignment and inducing the driver's sight line. For road sections where it is necessary to conduct sight guidance at night, set up reflective sight guidance signs.
Anti-glare facilities
The purpose of the anti-glare facility is to block the glare of the headlights of the opposite vehicle, and it is divided into two types: anti-glare net and anti-glare plate. The anti-glare net blocks the passage of light through the width and thickness of the mesh strands, reducing the intensity of the beam to prevent the dazzling of the headlights of the opposite car; the anti-glare plate is to block the beam of the headlights of the opposite car through its width.
