Summarize : Every station must become a cityIt is a boom in the construction of high-speed rail hub areas in China, but the actual development situation is not ideal.From the perspective of the customer group, LBS full travel chain quantitative analysis was used to evaluate the customer group structure, behavior characteristics and functional layout of 50 major high-speed rail hubs in the Yangtze River Delta. The study found that there was a "double threshold" phenomenon in the development of the hub area, the size and structure of the customer group. The functions of the hub area are related to the characteristics of people such as business, commuting and leisure of "station activities", and are divided into three categories: regional function-led, urban function-oriented and characteristic functionoriented. The functional layout takes 1.5 km around the hub as the core space, and the refined design that is aimed at the customer group and different from station to station is the core grasp to enhance the space in the hub area. In addition, customer groups and functions have a two-way effect and should be objectively understoodHub fixed customer group,Group setting function, the technical logic of functional layout, while paying attention to the reaction of space on the customer group, and building a smart platform to dynamically monitor customer group changes.
