some time ago
Mafengwo travel network united with several travel channels
The jointly released “Global Self-Driving Travel Report 2019” shows that
In 2018, China’s domestic self-driving tours reached 580 million
▼
In recent years
more and more people
After meeting basic material needs
Start pursuing a higher level of spiritual enjoyment
They love road trips
Apart from being free along the way
Beyond the beautiful scenery
Self-driving tour can also let you
Experience how developed China’s roads are!
According to the national road network plan
There are 200 ordinary national highways in China
(about 265,000 kilometers)
36 national highways
(about 118,000 kilometers)
▼ China National Expressway Network, (data as of 2009)
plus other roads
The total length reaches 4.7735 million kilometers
Enough to circle the earth 119 times
What is this concept?
Suppose we drive 300 kilometers a day
I want to travel all the roads in China
Need 15912 days
in years
That’s what you need to spend about 44 years
(Isn’t it exciting to spend half your life on the road?)

in our lives
highway as a
The most basic social transportation facilities
affect our life more or less
but when it comes to road numbers
In this era when going out depends on navigation
Even an old driver who has traveled all over the country
There are still many people who do not understand
Virtually all roads have
“Directions, Bearings, and Passwords”
▼ Do you know its password?
According to usage tasks, functions and traffic
China’s roads are divided into:
Expressway , National Road (G)
Provincial Road (S) , County Road (X) , Township Road (Y)
and each class road
Has its own direction and its own number
▼ G312 National Highway, starting from Huangpu District, Shanghai, and ending in Horgos City, Ili Autonomous Prefecture
Take national highway as an example
Numbered with the word “country”
Pinyin initial letter G plus 3 – digit code
▼
The first digit of the number is defined as 1 , 2 and 3
Such as G1XX, G2XX, G3XX three types
represents the direction of the road
The last two digits represent the sequence number
▼
Numbers start with ” 1 “
Represents Beijing as the center
Extending radially outward, a total of 12
National Highway 101 from Beijing to Shenyang
Arrange clockwise to National Highway 112
They are arranged in a clockwise rotation
When you are walking on a national highway numbered starting with 1
It means you are not staying away from the capital
on the way to the capital
▼ G109 National Highway, picture by “Self-driving Geography”
Number starts with ” 2 “
It represents the north-south vertical line , a total of 27 lines
From G201 to G228 (no G226)
Arranged from east to west
The first north-south vertical line in the east is
National Highway 201 from Hegang to Lvshunkou
When you walk on the national highway numbered starting with 2
means you’re either heading south
either up north
▼ G207 National Highway, picture by “Self-driving Geography”
Number starts with ” 3 “
It represents the east-west horizontal line , a total of 29 lines
From G301 to G330 (no G313)
Arranged from north to south
The first east-west line to the north is
National Highway 301 from Suifenhe to Manzhouli
When you walk on the national highway numbered starting with 3
Then you are either going east or west
▼ Sichuan-Tibet Line G318, picture by “Self-driving Geography”
But now there is one more number
I am used to seeing friends starting with 1, 2, 3
I might get confused as I walk.
“How can there be a national road starting with 5?”
▼
Turns out it was issued in 2013
“National Highway Network Planning 2013-2030”
There are 81 new national highways in total
These roads are numbered G5XX
2
Let’s talk about high speed
When unfortunately encountering a traffic jam on the highway
We might want to get off the highway and take the national highway
but here comes the problem
High speed also starts with G
How to distinguish which is the expressway and which is the national road?
▼ High speed? state Road?
High speed also starts with G and S
Divided into national expressway and provincial expressway
It seems to be the same as national highways and provincial highways
But there is still a certain difference
One of the differences is the number
National highways and provincial highways generally have 3 digits
while high speed is 1 , 2 , 4 digit
Such as G4, G50, G4212
and the highway
Above the number there will be
“National Expressway” , “Shanghai Expressway” and other signs
identity label
There are no national or provincial roads
▼ Look for the words “National Expressway”
besides
highway network
also includes the mainline
Parallel Line , Regional Circle Line ,
Contact Line and City Surrounding Line
Number of parallel routes
Add English letters to the main line number
“E、W、S、N”
Indicates the east-west, north-south orientation of the main line
▼ G4 is the Beijing-Hong Kong-Macau Expressway, and W3 is the third expressway parallel to the west of the main line G4
The number of the district loop
G91-G99 numbering from north to south
Among them, G99 is the Taiwan Ring Expressway
Take the meaning of “ninety-nine return to one”
▼
The contact line number is
Main line number + number 1 + connection line serial number
A total of 4 digits, the last two digits are in subscript form
If the main line number is 1 digit
Then fill in the front with the number 0
▼ Wenli Expressway Connection Line
The city loop is numbered
Main line number + number 0 + city ring line number
A total of 4 digits, the last two digits are in subscript form
If the main line number is 1 digit
Then fill in the front with the number 0
The main line number is the ring line
The one with the smallest number of connected vertical and horizontal lines
The order of the city circle line is arranged separately in each province (autonomous region, city)
Allowed in different provinces (autonomous regions, municipalities)
The same belt loop number appears
▼ G5001 Chongqing Ring Expressway
Although there are differences
But between expressways and national highways and provincial highways
There is also a certain connection
Some expressways are built on the basis of national highways
Such as National Highway 109
will be upgraded to highway
Form another high-grade highway to Beijing
Relieving the Beijing-Tibet Passage and
Traffic and transportation pressure on the Beijing-Hong Kong-Macao corridor
▼ National Highway 109 New Line Expressway, picture by “Highway and Railway Project Center”
2007
Promulgated by the Ministry of Communications of the People’s Republic of China
“National and Numbering Rules for National Expressway Network”
Intended to unify and standardize the national expressway network
Naming and Numbering Adjustment Work
new naming convention
In order of origin and destination of the route
Add the connector “-” in the middle of the place name of the origin and destination to form
The full name is “××－×× Expressway”
Or the first Chinese character of the place name of the origin and destination
Referred to as “××High Speed”
▼
and in the process of readjusting
There are already several provincial expressways
is slowly merging into the National Highway
Such as Chaoguan Expressway in Huidong
Take the abbreviation of Chaozhou and Dongguan
This provincial highway is also included in the
National Expressway – Ningguan Expressway (G15W3)
▼ S20 Chaoguan Expressway
above
Have you learned it all?
Once self-driving travel meets
traffic jam, road closure
Know the code for road numbers
You can freely switch between high-speed and national roads!
