3.1 Functions
Road traffic signs are facilities used to manage traffic by transmitting information to road users in terms of color, shape, characters, graphics, and the attention to the road traffic;
2) Prohibition signs: Signs to prohibit or restrict the traffic behavior of vehicles and pedestrians;
3) Indication signs: Signs indicating that vehicles and pedestrians shall follow;
4) Directional signs: Signs that convey the road direction, location,
distance information;
5) Tourist attraction sign: Signs indicating the direction and distance of the tourist attraction;
6) Work zone sign: Signs indicating the passage of the road work zone;
7) Notice sign: Signs indicating off-road facilities, safe driving information, other information.
b) Supplementary signs: Signs provided below the main sign to assist in the explanation.
3.3.2 Traffic signs are classified, according to the display position, into two types: roadside and above lane. The corresponding supporting structure is column type, roadside attachment type, cantilever type, gantry type, attachment type above lane.
3.3.3 Traffic signs are classified, according to the optical characteristics, into three categories: retroreflective, illuminating and luminous. The illuminating type is further divided into internal lighting type and external lighting type. 3.3.4 Traffic signs are classified, according to the display of the content of the layout, into static signs and variable information signs.
3.3.5 Traffic signs are classified, according to the set time efficiency, into permanent signs and temporary signs.
3.3.6 The traffic signs are classified, according to the mandatory degree of the information transmitted, into the mandatory signs and the non-mandatory signs. The prohibition signs and indication signs are signs that must be followed by the road users. Other signs only provide information, such as directional signs, tourist attraction signs. When the prohibition signs and indication signs are used on the frameless white baseplate, they must be followed. The signs to stop to give-way and the signs to decelerate to give-way shall not be used on the frameless white baseplate. The prohibition and indication signs which are used on the directional signs only provide relevant prohibition, limit, followed information, it can only be used as supplementary explanation or forecasting, meanwhile it shall provide corresponding prohibition and indication signs at the Table 3 -- Relationship between other texts and Chinese characters

3.7.4 The letter identifier and number in the road number identification are equal in height. The number and letter in the exit number sign are not equal in height, the height shall be selected according to the design speed from the Table 4. The specific requirements for the height of letter identifier and number of the number identification of the national highway are in accordance with Appendix B. For the road number or road name which is identified in the arrow bar of the directional sign of general road, the height may be appropriately reduced, which generally takes 0.5 ~ 0.7 times the value as specified in Table 2, but the height of the character of the road number or the road name shall not be less than 20 cm, the height of English letters and Arabic numerals shall not be less than 15 cm. The character height of the directional sign as set in the directional sign layout may be appropriately reduced, but shall not be less than 0.5 times the value as specified in Table 2.

3.11 Retroreflective materials and lighting
3.11.1 General requirements
Unless otherwise specified, the sign shall be made of retroreflective materials for the sign surface or be equipped with lighting facilities; or may be luminous type according to the terrain and sunshine conditions. The color of the sign during the day and night shall meet the requirements of GB 5768.1.
3.11.2 Retroreflective material
3.11.2.1 The retroreflective material used for the sign surface is mainly a reflective film. The retroreflective properties of the reflective film shall comply with the provisions of GB/T 18833.
3.11.2.2 The choice of retroreflective materials shall take into account the following principles or factors:
a) The sign for the road which has high impact of background environment, high driving speed, large traffic flow should use materials with good
retroreflective performance;
b) Gantry-type signs, cantilevered signs and attached signs above the lane should use materials with better retroreflective performance than roadside column signs and roadside attached signs;
c) For roads of grade 4 and below, roads with a small traffic flow may, depending on the actual situation, select materials with lower
retroreflective performance than the signs for other roads.
3.11.3 Illumination
3.11.3.1 The illumination of traffic signs shall be white light source, which is installed inside or above the sign plate structure or at other appropriate locations.
3.11.3.2 Internal illumination is the illumination method for installing the light source inside the sign plate structure. It is divided into single-sided display and double-sided display. The requirements are as follows:
a) The internal illumination signs shall be designed according to the size of the plate surface, the wind pressure, etc.;
b) Ensure that the sign surface is evenly illuminated and has a viewing distance of 150 m or more at night;
c) The metal components shall be qualified by anti-corrosion treatment, rainproof and dustproof, the electrical components are durable and
reliable, the maintenance is convenient.
3.11.3.3 External illumination is an illumination method of installing the light source above the sign plate to illuminate the sign surface. The requirements are as follows:
a) The color rendering index Ra of the selected external illumination source shall not be lower than 80, the light source shall be specially designed, the lighting fixture and its shadow shall not affect the reading of sign;
b) The illuminance of the light source on the sign surface shall be uniform, the ratio of the maximum illuminance to the minimum illuminance shall be less than 4, there shall be a viewing distance of more than 150 m at night; c) External illumination sources shall not cause glare;
d) The components supporting the luminaire shall be qualified for rust
prevention, the illumination device shall be durable and reliable, with excellent performance and convenient maintenance.
3.11.4 Active luminating
