Optimization Design of Interchange Space for Shanghai Rail Transit Zhongshan Park Interchange Station

Taking Shanghai Rail Transit Zhongshan Park Interchange Station as an example, the space features and interchange passenger volume characteristics of the elevated-underground station are analyzed. It is summarized that the main factors restraining the interchange efficiency and travel experience is the inadequate vertical traffic, insufficient underground interchange passage capacity and the lack of accessibility facilities. A systematic optimization strategy of the interchange station is proposed, including vertical traffic capacity enhancement, route optimization and appropriate diversion，of streamlines as well as overall spatial experience improvement.
