Abstract:To guild a reasonable pedestrian distribution in high rise commercial space is one of key problems in the design of high rise commercial complex. Pedestrian distribution in two rail transit commercial complex in Shanghai was studied by spatial configuration analysis with spatial syntax software and quantification of function and space (relationship with building entrances, distance to escalators, level, passage width and so on). Additionally in an attempt to integrate function with spatial configuration, two combination variables, spatial coefficient of function and spatial depth coefficient of function, were proposed, and SPSS(Statistical Product and Service Solutions) software was used to perform multiple regression analysis for pedestrian distribution. The analysis result reflects: ① space choice behavior has a certain rule in high rise commercial space, and customers’ purposiveness, function and space factors determines the flow distribution; ② comprehensive analytic model developed by spatial depth coefficient of function, space depth,relationship with building entrances, and distance to escalators, can well interpret flow distribution in high rise commercial complex and its determination coefficient can be up to 71.6% and 78.2%.
