What are the letters g, s, x and y on the road signs? On 9 september, the ministry of transport and communications carried out a full-scale science programme with msc。
According to the ministry of transport and communications, according to the rules on the marking of road routes and the state road number (gb/t 917-2017), the first administrative grade of the road line number represents the administrative grade of the road, expressed in a single letter, comprising g (guo country, national highways, including the national highway, and general national highways), s (sheng province, provincial roads, including provincial highways and ordinary provincial roads), x (xian county, county lanes), y (sangkat, and county repeats, x-post to one letter y), c (cun village, village lanes) and z (zhuan specific roads)。
The route number of the ordinary road (general state road, general provincial road, county rural road and special highway) is indicated by the combination of a road administrative class letter “g(s/x/y/c/z)” and a three-digit group “xx”。
The first number of the national highway is indicated by a national highway alphanumerator “g”. Of these, the main line numbers of the capital's radiology, north-south, east-west and area ring lines are indicated by the combination of a country-route letter identifier, “g”, and no more than two numeral numbers, “x” or “x”; the city-turned roundabout, contact line and parallel line numbers are indicated by a country-way letter identifier, “g”, and two main lines, “xx”, a route-type identification number, “*” and a serial number, “#”, with four digit numbers. The numbering structure is as follows:
The figure below shows, for example, the marking of the longest highway in the country, the g30 company high highway (lian yunport to holgos highway). It is marked “national high speed”, with an east-westerly-high speed line, followed by a national track identifier, g, and a double even number of 30。
According to the recent national road network plan (2022-2035), the urban circle has been added to the above-mentioned high-speed categories, with the g99+ double digit number being used provisionally。
The provincial highway number is first indicated by a provincial alphabet identifier, “s”. Of these, the main line numbers of the provincial centre radiology, north-south and east-west lines shall be indicated by a provincial alphanumerator “s” and a group of not more than two digital numbers “x” or “x” and the number of the urban roundabout and contact lines, which may be appropriate for a provincial alphabet identifier “s” and a group of two digital numbers “xx”. The numbering structure is as follows:
The highway above the provincial highway is marked in yellow and black, with the designation “provincial abbreviations + high speed”, such as “su-high speed” and “zen-high speed”. S and one to two digits。
There are, however, some provinces with particularly dense provincial highway networks, such as guangdong, where s1-s99 is no longer fully covered by all provincial high-speed networks, and some of the shorter lines of communication are also composed of s+4 figures。
