The urban landscape is an objective-subjective nature that plays a significant role in the perception of collective spaces by the audience. This is possible only by s timulating the perceptual potentials of users and inducing behavioral patterns to users of a space. This s tudy inves tigates the role of urban landscaping in the perception of collective spaces using perceptual potentials. This research is descriptive-analytical and, in terms of purpose, is applied. A ques tionnaire did data collection, and for data analysis, Spearman and Friedman's s tatis tical tes ts were used in SPSS software. A case s tudy is the third square of Tehranpars, where the target community has also been selected as users of this space. In the data collected from the sample group, the highes t level of correlation between the sub-components of objective aes thetics is the composition and color indices with a correlation coefficient of .۸۵۷. Among the sub-components of subjective aes thetics, the penumbra indices and physical cohesion with a correlation coefficient of ۰.۶۹۰ have the highes t level. In addition to the relationship between the proposed indices, the priority of these indices is ranked based on the Friedman tes t, and it is observed that the indices of composition (۷.۹۸), readability (۵.۸۹), and physical coherence (۵.۷۶) have the highes t priority among the ranking of indices in terms of the s tatis tical population. These data-driven priorities can identify design priorities and help take adequate s teps to create a vitality urban space.
