What is the difference between a national highway and a motorway? Which canonical?

National highways refer to the main trunk highways with national political and economic significance, including important international highways, national defense highways, highways connecting the capital and the capitals of provinces, autonomous regions and municipalities directly under the Central Government, and highways connecting major economic centers, port and station hubs, commodity production bases and strategic places. The inter-provincial expressways in the national highway shall be constructed, maintained and managed by a special agency approved by the Ministry of Communications.

Expressway refers to "a highway that can adapt to the annual average day and night passenger car traffic of more than 25,000 vehicles, and is dedicated to high-speed driving of cars in separate lanes, and all access is controlled". Generally, it can adapt to the speed of 120 kilometers per hour or higher, and requires a smooth route, a gentle longitudinal slope, and a width of more than 4 lanes on the road. A separator is arranged in the middle, asphalt concrete or cement concrete advanced pavement is adopted, and a complete set of signs, markings, signals and lighting devices are provided to ensure driving safety; It is forbidden for pedestrians and non-motorized vehicles to walk on the road, and to use three-dimensional crossings, pedestrian cross-line bridges or tunnels with other routes.

In contrast, the national highway is semi-closed, which can be passed by motor vehicles, non-motor vehicles, and pedestrians, and the highway is closed, and only motor vehicles with a maximum speed of not less than 60 kilometers per hour are allowed to pass, and the highway is tolled, and the national highway is not charged or has a low fee.

Technical Standards for Highway Engineering

The method of separating expressways and national highways is as follows: 1. Although national highways and expressways start with G, national highways are not high-speed. In terms of speed limits, the allowable speed range is 60-80 km h on national highways and 60-120 km h on highways.

In terms of speed alone, national highways do not belong to high speed; 2. The national highway is named in the fixed form of G3 digits, such as G321 National Highway; The high-speed is named in the form of G1 digit, 2 digit or 3 digits, such as the G2 expressway from Beijing to Shanghai, the G50 expressway from Shanghai to Chongqing, and the G4212 expressway from Hefei to Anqing. Highway signs are in white and green, while national highways are in white and red; 3. There are many people on the Internet who say that they would rather take the national highway than take the highway, saying that the highway has too many rules and is too dangerous. It is undeniable that there are indeed more rules on expressways than on general roads such as national highways, and the departments that manage expressways are all provincial-level departments, and they are relatively strict about highway violations.

As for whether it is a high-speed danger or a national highway danger, in fact, it is only a matter of opinion.

1.The difference between the national highway and the highway Gongfeng Xiangxi Road, the grading standard for the merger of expressways. According to the provisions of Article 6 of the Highway Law of the People's Republic of China, highways are divided into lanes, provincial roads, county roads, and township roads according to their location in the road network, and are divided into expressways, expressways, secondary roads, Yinhu expressways, and fourth-class highways according to their technical grades.

2.Therefore, highways may be expressways, highways, secondary roads, expressways, and fourth-class highways, and national highways may also be national highways, provincial roads, county roads, and township roads.

3.National highways refer to domestic economic arterial highways. If you want to ask what is the difference between roads other than highways?

4.According to the provisions of the "Technical Standards for Highway Engineering", expressways refer to "expressways that can adapt to the annual average day and night traffic volume of passenger cars, cars can drive at high speed in a single lane, and all entrances and exits are controlled".

5.The biggest difference between expressways and other roads is that expressways are closed, high-speed, with a limited minimum speed of feasting cherry blossoms, and are made up of vehicles. Other roads do not have this requirement.

Although both national highways and highways start with G, there is a big difference between national highways and highways, so what is the difference between taking national highways and highways?

1. The division standards are different, the national highway is mainly determined according to the importance of the road in the road network planning, and the highway is mainly determined according to the technical level of the road structure.

2. The coverage is different, the national highway is the nature of the representative highway, and in simple terms, it is the national trunk highway. Highway represents the grade of the highway, so some national highways are highways, some are first-class roads, and some are second-class roads.

3. The signs are different, as long as there is a green background, this kind of highway belongs to the highway. As long as it has a red background, this is a national highway.

4. The naming method of national highways is generally determined by using G+3 digit fixed methods, such as G321 National Highway. However, the naming method of expressways is mainly determined by G+1 digits, 2 digits or 3 digits, such as the G2 expressway from Beijing to Shanghai.

Legal analysis: The differences between national highways and highways are: 1. The allowable speed range is different

The permissible speed range on national highways is 60 to 80 kilometers per hour; The permissible speed range for high-speed vehicles is 60 to 120 kilometers per hour. 2. Different naming forms: national highways are named in a fixed form of G plus 3 digits; High speed is named in the form of g plus 1 digit, 2 digits, or 3 digits.

National highways refer to the main trunk highways with national political and economic significance, including important international highways, national defense highways, highways connecting the capital and the capitals of provinces, autonomous regions and municipalities directly under the Central Government, and highways connecting major economic centers, port and station hubs, commodity production bases and strategic places. Expressways are referred to as expressways, which refer to highways dedicated to high-speed driving of automobiles. Expressways have different regulations and slowdowns in different countries and regions, different times and different scientific research and academic fields.

Legal basis: Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China Article 78 The highway shall indicate the residual driving speed of the lane, the maximum speed shall not exceed 120 kilometers per hour, and the minimum speed shall not be less than 60 kilometers per hour.

The maximum speed of a small passenger car on a highway must not exceed 120 kilometers per hour, 100 kilometers per hour for other motor vehicles, and 80 volts per hour for motorcycles.

If there are 2 lanes in the same direction, the minimum speed in the left lane is 100 kilometers per hour; If there are more than three lanes in the same direction, the minimum speed is 110 km/h in the leftmost lane and 90 km/h in the middle lane. If the speed indicated by the road speed limit sign is inconsistent with the speed regulation of the above-mentioned lane, the speed indicated by the road speed limit sign shall be followed.
