On July 6th, the reporter learned from the Guangzhou Municipal Bureau of Planning and Natural Resources that the "Transportation Interconnection Plan between Guangzhou and Surrounding Cities in the Context of Land and Space" (hereinafter referred to as the "Plan") has been prepared. Guangzhou and surrounding cities will have 210 planned channels (59 tracks and 151 roads), which will be accessible to the city center of the Bay Area in one hour, and build a Guangzhou Foshan one network and a multi channel urban rail network in Guangzhou and Dongguan, Promote the formation of an interconnected transportation network with surrounding cities, consisting of multi-level highways and railways, multiple directions and paths, interconnected networks, and fast central transportation. The "Three Networks" support the development pattern of the metropolitan area. The "Plan" focuses on building the "Three Networks" with stronger regional transportation resilience, better travel quality in the bay area, and higher efficiency of urban commuting. In terms of building a national skeleton network, smooth domestic circulation support capacity. The "Plan" proposes that Guangzhou plans to build a "two person+three horizontal" national railway network, efficiently connecting the entire province and reaching major urban agglomerations nationwide; Both expansion and construction will be carried out to promote the establishment and rooting of the "Two Rings and Sixteen Shoots" national trunk network, forming 33 national skeleton external channels. In terms of strengthening the trunk network in the Bay Area, enhance the ability to drive pole radiation. Guangzhou will build a "double ring+cross+radiation" bay area intercity network around the Guangfo Center, and create a multi-level bay area trunk line network with the "three ring and nineteen radiation" expressway as the skeleton, forming 63 bay area trunk lines for external channels. Enhance commuting support capabilities in the area of dense urban branch network. Guangzhou will build a network of Guangzhou and Foshan, a multi channel urban rail network in Guangzhou and Dongguan, and a dense network of local road branches to smooth the microcirculation in border areas and form 114 external channels of local branch lines. After the implementation of the "Plan", there are more than two national railways and expressways from Guangzhou to various directions, which are accessible to the city center of the Bay Area within one hour. The peak hour commuting traffic range of the center has been expanded from 15km to 30km in the Foshan direction and from 30km to 50km in the Dongguan direction. The overall goal of the "Plan" is to create an "omnidirectional multi-layer three-dimensional network, efficient and convenient transportation circle". It aims to build a modern comprehensive three-dimensional transportation network that efficiently connects the world, conveniently radiates to the whole country, and quickly and directly connects to the Bay Area, forming a "1-hour transportation circle in the Bay Area" and a "1-hour commuting circle in the neighboring Guangzhou area", promoting the three-dimensional network of transportation infrastructure between Guangzhou and surrounding cities, supporting core guidance, axis support The development pattern of urban circles with interconnected circles. It is worth noting that the total demand for intercity communication has increased exponentially. During the preparation process of this "Plan", it actively contacted 7 surrounding cities such as Shenzhen, Foshan, Dongguan, Zhongshan, Huizhou, Qingyuan, and Shaoguan, and conducted in-depth research on the "Transportation Interconnection Plan between Guangzhou and Surrounding Cities". Based on regional and urban development directions, it analyzed the trend of population and economic agglomeration, Forecast and analyze the characteristics of transportation demand between "future cities": firstly, the regional economic correlation is strengthened, and the total demand for intercity communication is increasing exponentially. The economic correlation between Guangzhou and surrounding cities has increased by 1.8 times, and the frequency of cross city travel has increased by 65%. The total number of outbound trips has increased from a daily average of 4.03 million to 7.66 million, including 30% of transit traffic, reaching 10.85 million, an increase of nearly double. The second is the high-frequency output of medium and short distances
