In the context of accelerating the construction of a strong transportation country, as the cornerstone of supporting economic development, its importance is self-evident. . Recently, the Yunnan Provincial Party Committee and the Provincial Government issued the "Planning Outline of Comprehensive Three-dimensional Transportation Network in Yunnan Province", which proposed to improve the grid layout of comprehensive three-dimensional transportation, promote the coordinated and integrated development of comprehensive transportation, and promote the high-quality development of comprehensive transportation, so as to create a comprehensive transportation network oriented towards South Asia and Southeast Asia. The world's international comprehensive transportation gateway hub, building a new land-sea channel connecting the Pacific Ocean and the Indian Ocean.

According to the "Outline", by 2035, Yunnan will basically build a modern comprehensive three-dimensional transportation network that is convenient, smooth, economical, efficient, green, intensive, intelligent, advanced, safe and reliable. It will basically realize that the county-level administrative center can access the national highway in 15 minutes and the expressway in 30 minutes. , 60 minutes to the railway, 45 minutes to the state (city) level administrative center, 45 minutes to the high-speed railway, 60 minutes to the airport.

Yunnan is located in the southwestern border of China, and there is a strong demand for cross-border transportation. The "Outline" proposes to build a comprehensive transportation and economic corridor of "2 corridors, 4 belts and 5 axes", namely China-Indochina Peninsula, Bangladesh, China, India and Myanmar 2 international comprehensive transportation and economic corridors, Kunming-Beijing-Tianjin-Hebei, Yangtze River Delta, Guangdong-Hong Kong-Macao Greater Bay Area and There are 4 domestic comprehensive transportation and economic corridors in Tibet, and 5 comprehensive transportation and economic axes in the province, including the urban agglomeration in central Yunnan, along the border, northeast Yunnan-southeast Yunnan, west Yunnan-southern Yunnan, and northwest Yunnan-northeast Yunnan. Yunnan will give full play to its advantages in the location of major channels and bridgeheads open to South Asia, Southeast Asia and the Indian Ocean Rim, and vigorously enhance the radiation energy level of the international gateway transportation hub.

Combining the characteristics of future transportation development and spatial distribution, the "Outline" lays out the "555" comprehensive transportation corridor, forming a spatial layout that is open to the outside world, regionally balanced, and interconnected, providing strong support for the construction of the "2 corridors, 4 belts and 5 axes" transportation and economic corridors. Strong support. Among them, 5 international comprehensive transportation corridors are China-Vietnam Corridor, China-Laos-Thailand Corridor, China-Myanmar Ruili Corridor, China-Myanmar Qingshuihe Corridor, China-Myanmar-India Corridor, and 5 domestic comprehensive transportation corridors are Beijing (Rong)-Kunming Corridor, Beijing-Myanmar Corridor (Chongqing)-Kunming Corridor, Shanghai-Kunming Corridor, Guang-Kun Corridor, Yunnan-Tibet Corridor, and the five comprehensive transportation corridors in the province are the Central Yunnan Urban Group Corridor, the Border Corridor, the Eastern Corridor, the Western Corridor, and the Northern Corridor.

The "Outline" coordinates the spatial layout of various transportation modes, focuses on making up for shortcomings, re-connecting, optimizing the network, and improving efficiency, and pays more attention to the optimal utilization of stock resources and the improvement of incremental supply quality, and clearly forms a "high-quality fast network + high-efficiency trunk network". + a comprehensive three-dimensional transportation network with wide coverage of the basic network. By 2035, the total scale of the province's comprehensive three-dimensional transportation network physical network will reach about 400,000 kilometers. Among them, the total scale of the railway network is about 12,000 kilometers, the total scale of the road network is about 383,000 kilometers, the total scale of the waterway is about 5,300 kilometers, there are 29 civil transport airports, 105 general airports, and 19 postal exchange hubs. Keywords: infrastructure, infrastructure construction, domestic engineering news, planning and investment

In order to promote the integrated development of regional transportation, the "Outline" proposes to take the central Yunnan urban agglomeration as the core, and promote the "four-network integration" of trunk railways, intercity railways, urban (suburban) railways, and urban rail transit, so as to create a "central Yunnan city on the track". To improve the traffic level of the central Yunnan urban agglomeration facing the radiation center of South Asia and Southeast Asia, strengthen the interconnection between Kunming and Yuxi, Qujing, Chuxiong, Honghe and other prefectures (cities), and improve the overall efficiency of the comprehensive transportation hub system of the urban agglomeration and the international Competitiveness.
