china high speed way
The Shenyang-Dalian expressway, which was built earlier than expressway, Hu Jia, has been completed and opened to traffic for 239 kilometers from June 27th to 27th, 0984 1988. (In addition to the first-class highway in the middle section of Shenda Road, two fully interconnected, fully enclosed and fully controlled toll roads, namely * *131km, have been built from Shenyang to Anshan and from Dalian to Sanlipu, achieving a zero breakthrough in expressway, Chinese mainland. As of 20123,000 km, the total mileage of expressway in China has reached123,000 km, surpassing the United States and ranking first in the world.
China's vast territory and great differences in topography bring great challenges to the construction of expressway. The early construction of expressway started from areas with developed economy and relatively difficult construction. With the gradual implementation of the national trunk highway planning ("five vertical and seven horizontal planning"), in order to meet the requirements of networking, the construction focus has also shifted to areas with complex terrain, the proportion of long tunnels and long-span bridges has increased, and the average cost of expressway has also increased significantly. Since 1990s, China has entered a period of rapid development of expressway's construction, especially since 1998, when China implemented a proactive fiscal policy, China has invested a lot of money in expressway's construction and started many projects.
According to the management and strategic significance, expressway in China is mainly divided into two categories: national expressway and provincial expressway. Among them, the national expressway is of national strategic significance, connecting cities across the country; Inter-provincial expressway is of strategic significance in the province, which mainly connects the cities of this province and neighboring provinces.
Some lines have low design standards, leading to collapse, causing doubts and needing improvement.
Planning and numbering
National highway planning and numbering
Numbering structure
The number of China expressway network consists of letter identifiers and Arabic numerals.
Alphabetic identifier
China expressway is an important part of the National expressway Network, and the route letter logo is represented by the Chinese phonetic alphabet "G"; The serial number of the main line of China National expressway Network consists of the China expressway identifier "G" plus 1 or a 2-digit serial number, and the serial number structure is "G#" or "G##".
Numbers and numbers and letter numbers
(1) The number of Capital Radiation is 1 digit, starting from Beijing and ending at the stop point of radiation. The starting point is 1 expressway, and it is numbered clockwise along the route, with the numbering interval of G 1 ~ G9.
(2) The longitudinal route starts at the northern end and ends at the southern end, and is arranged from east to west along the longitudinal direction of the route. The route number is odd, and the numbering interval is G 1 1 ~ G89.
(3) The horizontal route starts at the eastern end and ends at the western end, and is arranged from north to south along the horizontal direction of the route. The route number is even, and the number interval is G 10~G90 ~ G90.
(4) The serial number of the parallel route is represented by the combination of the main line number followed by the English letters "e", "w", "s" and "n", indicating that the parallel route is located in the east, west, south and north of the main line respectively.
(5) The regional loop lines (such as the Pearl River Delta loop line) included in the China National expressway Network are numbered G91~ G99 from north to south; Among them, the ring road number of Taiwan Province Province is G99, which means "99 ratio 1".
(6) The serial number of the main connecting line of China National expressway Network consists of the national expressway logo "G"+"main line number"+the number "1"+"main connecting line serial number", and the serial number is 4 digits. When making signboards, the font size of the last two digits is less than the main line number, which is about half of the main line number.
(7) The serial number of the ring road is 4 digits, consisting of "g"+"main line number"+number "0"+ring road serial number. The serial number of the main line is the one with the smallest serial number of the vertical line and the horizontal line connected by the circular line. If the serial number space around the city where the main line is located has been fully utilized, the one with the smallest serial number is selected, and so on. If the loop line has only radial connection, it should be filled with the number "0" before the 1 bit main line number. [2] When making signboards, the font size of the last two digits is less than the main line number, which is about half of the main line number.
(8) Before the promulgation of the national highway planning, twelve national highways were planned, namely five longitudinal highways and seven transverse highways. These twelve highways are numbered in the same way as other national highways, with longitudinal lines G0 10, G020, G030, G040 and G050 respectively, and horizontal lines G0 15, G065 and G050 respectively.
shop sign
Each expressway has its own signboard, which is made according to the format specification of the National expressway Network.
(1) The signboard is rectangular with rounded corners and green characters on a white background. The interior is painted with borders and white lines, which are thicker.
(2) The signboard is "two-section", the upper section is similar to a banner, with white characters on a red background and the words "National Highway" in bold, which is a powerful symbol of the national highway.
(3) The lower paragraph is the main part, with white characters on a green background and two lines. The upper line is the number of expressway, printed in bold, and the font size is large enough to make the overall width of the text flush with the border. The following line is optional, it is the name of expressway, and it is also printed in bold, and the overall width of the word is required to be flush with the border.
(4) If expressway is a tie line or ring road, its signs are different from the main roads:
(1) The number is two more than the main expressway, so the signboard is wider;
(2) The number of redundant two digits is less than the number of main lines, which is about half of the number of main lines.
Provincial high-speed planning and numbering
Numbering structure
Corresponding to expressway, China's provincial expressway network number consists of letter identifiers and Arabic numerals.
Alphabetic identifier
Corresponding to the national expressway, expressway, China Province, is an important part of the provincial highway network (provincial highway network), and the route letter logo is represented by the Chinese phonetic alphabet "S"; The serial number of provincial expressway mainline consists of China provincial expressway identifier "S" plus 1 or 2 digit serial number, and the serial number structure is "S#" or "S##".
Numbers and numbers and letter numbers
(1) Theoretically speaking, the number of expressway radially extending from provincial capital cities is 1 digit, but only a few provincial capital cities such as Guangzhou and Tianjin can be marked in this way (e.g. s 1 Jinji Expressway and S2 Jinning Expressway). In most cases, the number of provincial-level expressway is double-digit, even in expressway with the provincial capital as the radiation point (such as S 15 Beijing-Tianjin Expressway and S55 Nanjing Airport Expressway).
(two) corresponding to the national highway, the longitudinal route starts at the northern end and ends at the southern end, and is arranged in the longitudinal order of the route from east to west, and the route number is two odd digits.
(3) Corresponding to the national expressway, the horizontal route starts at the eastern end and ends at the western section, and is arranged from north to south along the horizontal direction of the route, with even route numbers.
(4) The serial number of the ring road or expressway is three or four digits, which consists of "S"+"main line number"+"0"+the serial number of the ring road or expressway. Different from the National expressway Network, if the loop is only connected radially, the number "0" will not be filled in front of the 1 digit main line number. For example, the main line number of S303 South China Expressway in Guangzhou is S3.
(5) As the standards of expressway in different provinces may be different, the specific numbering rules shall be subject to local regulations.
shop sign
The styles of provincial road signs are basically the same as those of national roads, but there are several differences in details:
(1) The banner on the upper section of the signboard is written in black on a yellow background or in black on an orange background, marked with the abbreviation of the provincial administrative region (one word, usually the same as the abbreviation of the administrative region on the local license plate), followed by the word "expressway". For example, the provincial highways in Beijing are marked as "Beijing Expressway", Shanghai Expressway, Guangxi Expressway, Inner Mongolia Expressway, and so on.
(2) Note that the letter sign is "S", which is the most intuitive sign to distinguish national and provincial roads.
Five vertical and seven horizontal.
1992, People's Republic of China (PRC) * * and the Ministry of Communications formulated a national trunk line plan with five vertical lines and seven horizontal lines, and planned to build an inter-provincial expressway system, including 12 key traffic corridors with five vertical lines and seven horizontal lines (five north-south lines and seven east-west lines), with a length of 35,000 kilometers, all of which are composed of high-grade highways above secondary roads, including 25,000 kilometers in expressway. China municipal government plans to build a expressway network with five verticals and seven horizontals before 20 10 (two verticals and two horizontals are planned to be basically completed in 2002). Upon completion, it will run through the capital Beijing, municipalities directly under the Central Government and capital cities of provinces (autonomous regions), connecting all megacities with a population of over 1 10,000 and 93% megacities with a population of over 500,000, bringing the total number of networked cities to more than 200. With the rapid development of China's economy, the Ministry of Communications published a new National Highway Network Plan in June 2005, namely 79 18 Network.

Naming rules
The naming of national highway network routes should follow the general rules of highway naming.
(1) The route name of the National expressway Network consists of the starting point and the ending point of the route in sequence, with a connector "-"between the place names of the starting point and the ending point, which is called "XX-XX expressway". The abbreviation of the route is expressed by the first Chinese character of the place name of the starting and ending point, or by the abbreviation of the province (city) where the starting and ending point is located, and the format is "××× expressway".
(two) the national highway network route name and abbreviation can not be repeated. If there is any duplication, it shall be distinguished by the second or third Chinese character of the administrative division name.
(3) The name of the regional loop of the National expressway Network is called "XX regional loop expressway" or "XX loop expressway" for short. Such as "Hangzhou Bay Area Ring Expressway", referred to as "Hangzhou Bay Ring Expressway".
(4) The ring road name of the National expressway Network is named after the city name, which is referred to as "XX Ring Expressway" or "XX Ring Expressway". Such as "Shenyang Ring Expressway", referred to as "Shenyang Ring Expressway".
(5) When the starting and ending points of two or more road sections are the same, they shall be named "××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××× Referred to as "×× expressway East (Central and West) Line" or "××× expressway North (Central and South) Line".
(six) the name of the route should be spelled in Chinese characters or Roman letters. The place names of the starting and ending points of the route should take the single name of the main administrative division, which is generally the name of the administrative division at or above the county level.
(7) The north-south longitudinal route starts at the northern end of the route and ends at the southern end of the route; The east-west horizontal route starts from the eastern end of the route and ends at the western end of the route. The starting point of radiation is Beijing.
