Urban landscapes form the main parts of the city. One of these spaces is urban streets, in which social interactions and urban vitality reach its maximum quality and quantity. One of the principles and properties of urban landscape design is its intelligibility. A viewer who takes a look at an intelligible city and knows it can attract new emotional manifestations of city without damaging its original image. Orientation is also very easy for the viewer and he completely knows the environment he lives in. numerous characteristics influence the legibility of urban landscapes. The current research, which is a descriptive- analytic study, is designed to identify the factors influencing legibility of urban landscape and citizen participation as the main bases of visual preference technique. First we begin with concepts, ideas and attitudes of experts inside and outside the country about “landscape, legibility, urban streets” and identification of visual preference technique by investigating some foreign examples is done by collecting principles and characteristics to coordinate the components of city even more. Finally, considering the citizens (residents and non-residents) participation based on surveys and evaluations that have always carried thoughts and ideas about the environment, it was clarified that in different age groups, no fear should be held for the development of this technique. However, considering the new ideas of citizens, criteria are proposed to create and reinforce legible landscapes for the streets and urban landscapes.
