Abstract:

Due to the natural advantage of pedestrian flow in rail transit hubs, three-dimensional and composite commercial space above rail transit hub has become a new construction model. The commercial space above rail transit hub has become an important place for passengers, commuters, and citizens to engage in consumption and social activities. However, The development volume of most commercial space above rail transit hub is relatively large, and the spatial organization relationship is complex. It is easy to encounter problems such as mismatched functional requirements, insufficient supply of service facilities, chaotic flow organization, low transfer efficiency, and poor spatial quality, resulting in insufficient guidance of pedestrian flow and low space utilization, which affects the vitality of commercial spaces and thus affects the healthy operation of commercial spaces. Therefore, starting from the study of the vitality of commercial space on the top, the constituent elements of commercial space above rail transit hub are defined from three dimensions: functional organization, flow line organization, and spatial construction. Corresponding evaluation indicators are constructed, and data analysis methods such as spatial syntax theory and correlation analysis are introduced to quantitatively study typical cases built in China. The key elements that affect spatial vitality are summarized, and finally, design strategies are proposed based on practical projects, providing design references for future related designs and bringing new insights to related theoretical exploration.

Key words: rail transit hub; commercial space above rail transit hub, spatial vitality, design research
