The series interpret the article -create a modern and high -quality national highway network, and promote the modernization of urban agglomeration and urban circle traffic

The urban agglomeration is the main form of the new urbanization. The urban circle is the core of the urban agglomeration and an important carrier to promote the new urbanization. Accelerate the development of key urban agglomerations, enhance the population and economic carrying capacity of economic development advantages such as central cities and urban agglomerations, and require the construction of an integrated transportation network of urban agglomerations to further enhance the level of interconnection. Recently, with the consent of the State Council, the National Development and Reform Commission and the Ministry of Transport jointly issued the "National Highway Network Plan" (hereinafter referred to as the "Plan"). By 2035, it will basically build a wide range of coverage, complete functions, intensive efficiency, green intelligence, safe and reliable, reliable, reliable, and reliable. The modern high -quality national highway network has achieved multi -road connectivity between urban agglomerations, convenient urban agglomerations in urban agglomerations, high -level city -level cities high -speed smooth, and county -level nodes. The "Planning" is of great significance to build the city's integrated transportation network and build the urban circle commute transportation network to promote the first modernization of urban agglomeration and urban circle transportation.

1. Fully understand the important role of the national highway network in urban agglomeration and urban circle

The urban agglomeration and urban circle are areas with dense population and towns, concentrated industrial elements, and high level of economic development. Hualu urban passenger and freight services have an important role.

The first is to open up inter -regional comprehensive transportation channels. As an important part of the national comprehensive three -dimensional transportation network and the main skeleton, the National Highway Network plays an important role in improving the level of urban agglomeration and the level of joint and exterior of the urban agglomeration and the urban circle, active services and integrating into the major national development strategy. For example, the National Highway Beijing -Hong Kong -Macao Expressway (G4) runs through the north and south, and connects urban agglomerations such as Beijing -Tianjin -Hebei, Central Plains, Yangtze River Central reaches, Guangdong -Hong Kong -Macao Greater Bay Area, as well as Zhengzhou, Wuhan, Changzhu and other urban areas. The rapid connection between the circle has also strongly supports the Beijing -Tianjin -Hong Kong and Macao's main axis of the Beijing -Tianjin -Hebei -Guangdong -Hong Kong -Macao and the national "two horizontal and three verticals" urbanization pattern of the national comprehensive three -dimensional traffic network. The National Highway Shanghai -Chongqing Expressway (G50) span east to west, connecting the Yangtze River Delta, the middle reaches of the Yangtze River, and the Shuangcheng Economic Circle of the Chengdu -Chongqing area. The corridor provides strong support for traffic connections between the Yangtze River and the middle and lower reaches of the Yangtze River and the coordinated development of the east and central and western regions.

The second is to promote high -efficiency flow gathering of diversified elements. The efficient flow of elements between cities is the prerequisite for building a modern urban agglomeration and urban circle. The rapid development of the National Highway Network has greatly shortened the space -time distance between the provincial and cities, accelerating the circulation of diversified elements in the urban agglomeration and the urban circle, and realizing resource optimization allocation in a larger space. For example, the Shanghai G60 Science and Technology Corridor is based on the National Highway Shanghai -Kunming Expressway (G60) as the link, and connects Shanghai, Jiaxing, Hangzhou and other cities and major industrial parks and science and technology platforms along the line to accelerate the elements of talents, technology, funds, data resources and other elements. flow. During the three years of 2017 to 2020, the Shanghai -Hangzhou G60 Science and Technology Corridor won nearly 30 national scientific and technological awards including the first prize of national technology invention, and nearly 500 provincial and municipal science and technology awards, becoming the most important scientific and technological innovation in the Yangtze River Delta One of the highlands.

The third is to support the layout of the industrial space compact and efficient. The main corridors of urban agglomerations are dense, tightly connected between cities and towns, and the development trend of the development of the transportation corridor and the gathering of central cities is obvious. The construction of the National Highway Network, especially the national highway network, has greatly promoted the division of labor collaboration and organic connection between the central and node cities of the urban agglomeration, as well as the central city and suburban new cities of the urban circle, and support the support of urban space axis and industrial structure. Optimization has a important role in promoting the cooperative development of large and medium -sized cities. For example, the National Highway Shen Da Expressway (G15) is one of the earliest highways in China. In 1990, it opened to traffic in 1990, with a total length of 375 kilometers. It quickly connected industrial cities such as Shenyang, Liaoyang, Anshan, Yingkou, Dalian, and other industrial cities. The equipment manufacturing, petrochemical, shipbuilding, high -tech, steel and other industries are gathering along the line. In 2020, the GDP created by the city accounts for more than 70%of the province's GDP. The main passage of urban agglomerations.

The fourth is to facilitate diverse urban passenger and freight services. The total number of passenger and freight demand for urban agglomerations and urban circles is large and high in strength. Passenger transportation includes diversity of travel, business, commuting, leisure, and tourism. The rapid growth of freight demand and showing small batches and multiple batches. The National Highway Network has the characteristics of extensive coverage and intensive efficiency. By 2020, the national highway has basically covered the prefecture -level administrative center and the general national highway. Provide important support. From the perspective of passenger transportation, relying on the National Highway Network Tranper, Intercity Bus, Intercity Bus, Inter -Provincial Bus, etc., it has greatly facilitated the connection between urban agglomerations and urban circles. From the perspective of freight, the National Highway Network not only undertakes a large number of commodity transportation needs, but also effectively promotes the prosperity of short -range express logistics transportation. Through the transportation with aviation and railway joint transportation, it basically realizes the round -trip round -trip and 1,000 kilometers within 400 kilometers. Express "Daya" and "the next day" became the norm.

2. Accurately grasp the key issues of national highway network planning and construction of urban agglomerations and urban circles areas

The first is to coordinate division of labor and strengthen the function of national highways and trunk railways. Under the guidance of the strategic strategy of transportation, my country's comprehensive transportation system emphasizes integrated integration, more attention to water, land, and empty body multi -dimensional connection and collaboration. , Give full play to the comparative advantages and combination efficiency of various transportation methods, and build a national comprehensive three -dimensional traffic network based on railway -rails as the main trunks and highways, and the comparative advantages of water transportation and civil aviation. The "Planning" clearly proposes that the integrated construction of comprehensive transportation channels is coordinated, the lines of lines such as railway and highways and other infrastructure are coordinated, and the co -sharing of channels of the channel line positions will be promoted. Essence The second is diverse demand and promotes the coordination of national highways and local highways. The transportation demand for urban agglomerations and urban areas is high -intensity, diversification, high frequency, and strong time -effectiveness, especially in major urban corridors, industrial agglomeration and concentrated regions, intercity, suburbs, and cities. As the highest level of highway networks, the National Highway Network must not only use the functions of serving the intercity channels inside the urban group in the urban agglomeration, but also strengthen the division of labor with local highways to promote the integration of the national highway network and local provincial and municipal highways. Improve the "last mile" problem of highway networks in urban agglomerations and metropolitan area, and improve the level of "door -to -door" transportation services. The "Planning" proposes to strengthen the coordination and coordination of planning, strengthen the coordination of cross -departments, cross -regions, and cross -industry integration. When the provinces (autonomous regions, municipalities) are planned and constructed, they must strengthen the connection with this plan and coordinate the coordination of road networks at all levels. Development, reasonably determine the planning goals, construction scale, and construction timing.

Third, supply and demand is adapted to coordinate the construction and expansion of the new national highway. After nearly 10 years of development, the national highway and ordinary national highway layout have basically stable, and the overall needs of economic and social development. However, there are not high network levels in urban agglomerations and urban circles. The traffic volume of traffic sections between the intercity and the main cities and the urban circle transit sections is particularly needed to deal with the relationship between the construction of the new line and the expansion of existing road sections. The "Planning" proposes that the national highway network should strengthen the channel capabilities between urban agglomerations and key cities, strengthen the intercity channels and rapid channels inside the urban agglomeration, and increase some routes that improve the efficiency and toughness of the road network. In the recent construction focus, it is proposed that priority to open the main line and inter -provincial pending through section, realize the main line of the "71118" national highway, and promote the implementation of Beijing -Shanghai, Beijing, Hong Kong, Macao, Changshen, Shanghai -Kunming, Lianhuo and other national highway main lines to congestion congestion. The expansion of the road section is basically eliminated to realize the abroad of ordinary national roads and other exterior and penetration sections, and promote the transformation of the congested roads and urban transit sections in urban agglomerations.

The fourth is to coordinate and promote the organic connection between national highways and urban nodes. The national highway network should focus on the effective connection with urban nodes in urban agglomerations and urban circles, and coordinate foreign transportation, transit traffic, and commuting traffic to avoid various transportation and affect the overall efficiency of the road network. The "Planning" emphasizes the need to strengthen the connection and integration, pay attention to the effective connection with urban transportation, and improve the level of integrated integration and utilization of resource sets; and add 6 regions, 12 metropolitan ring lines, and 30 cities around the national highway network planning plan. City ring. At the same time, the integration and development of the national highway network and tourism and industries along the route is also of great significance to the supporting role of the national highway network for economic and social development. The "Planning" emphasizes that relying on the national highway network development channel economy, focusing on the deep integration of related industries such as tourism, manufacturing, logistics, and e -commerce along the route, guide and optimize the regional industrial layout, and promote the smooth operation of the industrial chain supply chain. Improve the quality of services in the road service area, set up humanized service facilities, charging and replacement, or hydrogenation facilities, and enrich the service functions such as cultural, tourism, leisure and other service functions according to local conditions. Implement the expansion of the service area on demand, and add a special parking area for large trucks or hazardous chemical vehicles.
