Abstract:In February 2021, the CPC Central Committee and the State Council issued the Outline of the National Comprehensive Three-dimensional Transportation Network Planning, and put forward the requirements of building a multi-level integrated national comprehensive transportation hub system and promoting the integrated planning and construction of comprehensive transportation hub. The development and construction of station-city comprehensive passenger transport hub based on the TOD development model in China have also ushered a very rare historical opportunity. Taking the comprehensive traffic planning and design scheme of an new high-speed railway city as an example, the integration of traffic inside and outside the hub, the layout of traffic facilities, the transfer and connection of various traffic modes, and the organization of main traffic lines in the station area are mainly studied, and the methods and strategies of comprehensive traffic planning and design of new high-speed railway city are discussed in order to provide reference for similar projects.
