Research on the Connection of Guangzhou Air and Railway under the Background of Guangdong-Hong Kong-Macau Greater Bay Area's Construction

In recent years, the construction of Guangdong-Hong Kong-Macao Great Bay Area has been in full swing. The development of Guangzhou airport economy has maintained a good momentum, and the construction of international aviation hub has accelerated. Meanwhile, Guangzhou railway hub has prominent location advantages, and the railway transportation network has gradually improved. How to improve the service of Guangzhou air-rail integration transport is directly related to the development of a comprehensive transportation system in Guangzhou. Through the demonstration of the conditions for the development of "air-rail integration transport" in Guangzhou, some shortcomings in “air-rail integration transport” have been analyzed. For example, there are relatively few metro lines for integration, and the railway hub has not yet been established. Some suggestions have been put forward to promote the construction of air-rail facilities, break down the barriers of air-rail sector, and improve the surrounding unban traffic.
