Shanxi Qijie Road Traffic Signs

Brief description of sign material processing:

　1. Materials use high-quality aluminum alloy plates, engineering grade or high-intensity reflective film, providing excellent reflectivity at night.

　2. Cut aluminum plates and reflective film according to national standard dimensions (square, circular).

　3. Clean the aluminum plate, polish it with a white cloth to roughen the surface, rinse with water, and air dry.

　4. Use a hydraulic machine to apply the reflective film onto the cleaned aluminum plate for later use.

　5. Typeset patterns and text on a computer, and use a computer engraving machine to directly engrave the patterns and text onto the reflective film.

　6. Press the engraved patterns and screen-printed patterns onto the aluminum plate with the base film using a squeegee to form the final product.

　Signs are installed at entrances and exits, inside parking lots, and at appropriate locations on roads to guide vehicles correctly. Traffic signs include prohibition signs, indication signs, and other types of signs.

Technical Requirements

　1. The installation of traffic signs should be comprehensively planned with a reasonable layout to prevent information deficiency or overload. Information should be connected, and important information should be repeated.

　2. Traffic signs should generally be installed on the right side of the road in the direction of travel or above the carriageway; they may also be installed on the left side or on both sides simultaneously depending on specific conditions.

　3. To ensure visibility, when more than two signs are needed at the same location, they can be installed on one support structure (support), but no more than four; separate the installation space for signs, indications, and warning signs.

　4. In principle, different types of signs should not be installed together. Signs such as speed limit removal, no-passing removal, intersection priority, oncoming vehicle priority, stop yield, and減速 yield should be installed separately. If conditions are limited and separate installation is not possible, no more than two types of signs should be installed on one support structure (support). When multiple sign plates are installed on one support structure, they should be arranged in the order of indication and warning, from top to bottom and left to right.

　5. Warning signs should not be over-installed. When more than one warning sign is needed at the same location,原則上 only the most necessary one should be installed. (Warning signs: alert vehicles and pedestrians to pay attention to the road ahead)

Modern road traffic signs in China are divided into two main categories: main signs and auxiliary signs. 1. Main Signs Main signs can be divided into four types based on their meaning: warning signs, prohibition signs, indication signs, and guide signs. (1) Warning signs. There are 23 types of warning signs, which alert vehicles and pedestrians to dangerous locations. Their shape is an upward-pointing equilateral triangle, with a yellow background, black border, and black圖案. (2) Prohibition signs. Prohibition signs prohibit or restrict the traffic behavior of vehicles and pedestrians. Their shapes include circles and downward-pointing equilateral triangles. Their colors, with few exceptions, are white background, red circle, red bar, black圖案, with the圖案 overlapping the bar. (3) Indication signs. There are 17 types of indication signs, which指示 vehicles and pedestrians on how to proceed. Their shapes include circles, rectangles, and squares, with a blue background and white圖案. (4) Guide signs. There are 20 types of guide signs, which provide information on road direction, location, and distance. Their shapes, except for location identification signs, are rectangles and squares. Their colors, except for milestones, hundred-meter posts, and highway boundary markers, are generally blue background with white圖案 for ordinary roads, and green background with white圖案 for highways. 2. Auxiliary Signs There are 5 types of auxiliary signs, which are附加 to main signs to provide additional explanation. These signs cannot be installed or used alone. Auxiliary signs are further divided into those indicating time, vehicle type, area distance, reason, and combined auxiliary signs. Their shape is rectangular, with a white background, black characters, and black border. Additionally, there are variable traffic information signs that display real-time information based on road conditions (such as construction, congestion, changes in flow and direction, weather conditions, etc.) to communicate with drivers and pedestrians.
