Research on the correlation between the characteristics of bottom-level interface of commercial complex and the pedestrian behavior around: based on environmental behavior quantification technology ABSTRACT This paper takes 30 commercial complexes in Wuhan, China as examples, based on literature, open data, observation experiment, environmental behavior research methods and environmental behavior quantification methods, SPSS software was used to analyze the correlation between the characteristics of the bottom-level interface of commercial complex and the pedestrian behavior around, the results show that the attractiveness of commercial complexes to surrounding pedestrians is strongly positively correlated with average transparency of bottom-level interface of commercial complex, and the intimacy degree of pedestrians around commercial complexes to commercial complexes is positively correlated with an average saturation of the color of the bottom-level interface of commercial complex. This means that through empirical research on various design factors of the commercial complex itself, explore the impact of the bottom-level interface of the commercial complex on the quality of urban space, and provide a data foundation and provides clues and experience, for planning and designing the high-quality bottom-level interface of commercial complex.
