  Visual aspect is one of those lots of aspects which influence neighborhood quality. Visibility is an important factor of environmental and urban quality. This study is concentrated to find whether the visual quality of housing and urban open space in the neighborhoods is influenced with urban form and its objective is to find the relationship between open space form of the neighborhood unique fabric, its organic pathways, a linear main access which divides this fabric to two parts and visibility. So open space visibility of neighborhood in old fabric of Bushehr and their isovist properties have been analyzed in a correlational research. The case study was a neighborhood public space in spatial configuration located in Bushehr that is surrounded by urban development and sea. Compact urban space, squares, long and narrow streets shape this fabric. One of the characteristics of this morphology is its composition as a set of rather long and narrow streets with number of squares different in shape.This study shows that isovist tool is applicable in analyzing visual quality in urban fabric. In this research two forms of urban open space has been analyzed to evaluate visibility using Syntax2D. Six isovist measures in grid and two paths have been studied that correlations between these measures have been compared with each other in two paths. Findings show that area and perimeter indices have the highest correlation. In organic path these two indices have highest value reaching Enghelab Avenue that divides this fabric in two parts and also these measures are higher in local squares than long and narrow streets. On the other hand these indices remain unchanged in linear path. Drift index that studies the longest possible line of sight raises dramatically reaching Enghelab Avenue while it almost stabilizes inside the organic path. Turning to linear path, this index is the highest at the ends and the lowest in the middle of the path. Occlusive index that is the proportion of the perimeter on the solid boundary of the environment Shows fluctuation in organic path unlike linear path. While Compactness index that shows how close the observers feels themselves to the environment shows notable variations in organic path having a steady graph in linear path. Circularity index that is the square of the perimeter to area as is influenced by details in space shows significant changes in organic path while it is nearly stabilized in linear path. It can be said as a result that urban form has relationship with its visibility; meaning that the organic path creates a variety of isovist indexes unlike linear path that divides the neighborhood fabric in two parts. Furthermore, the analysis shows that squares which are the place of social interactions are more compact than the streets of the neighborhood as they define non physical geometries and variety in the spatial experiences is achieved moving within them. Finally the study shows that the form of neighborhood open space plays an important role in its high visual quality and the quality of housing.   Manuscript profile

        The present study analyzes the entrance of Isfahan Bazaar saria with the aim of investigating the field of vision and the level of visual attractiveness as a place that a tourist encounters at the first glance, and evaluates the components of physical quality with an emphasis on It measures the field of view and the depth of the tourist's gaze angle. The main question of the research is what is the relationship between the tourist's point of view and the physical-spatial quality components in the direction of readability at the entrance of the historical bazaar of Isfahan? The answer to this question is proposed in the form of this hypothesis; It seems that the greater the field and the depth of the viewing angle, it has a greater effect on the legibility of the environment as one of the components of environmental quality.In the study of three categories of Saria (small, medium, large), it can be concluded that the length of the corridor, the model of the entrance (straight, broken or spiral), the location of the entrance (corner or middle of the longitudinal or transverse side), The shape of the yard (rectangular or square), the area of ​​the yard in the plan can have an effect on the field of view of the tourist. But the tourist field of view, Isovist view and angle analysis in all cases have no direct relationship with readability as one of the components of the physical quality of space.Extended AbstractIntroduction:    The present study analyzes the entrance of Isfahan Bazaar saria  with the aim of investigating the field of vision and the level of visual attractiveness as a place that a tourist encounters at the first glance, and evaluates the components of physical quality with an emphasis on It measures the field of view and the depth of the tourist's gaze angle. The main question of the research is what is the relationship between the tourist's point of view and the physical-spatial quality components in the direction of readability at the entrance of the historical bazaar of Isfahan? The answer to this question is proposed in the form of this hypothesis; It seems that the greater the field and the depth of the viewing angle, it has a greater effect on the legibility of the environment as one of the components of environmental quality Methodology.Results and discussion:      As a general result, it can be acknowledged that the observer's view from the Aizovist point of view does not have a direct relationship with readability as one of the components of the physical quality of the space. The vault of gifts is effective for attracting the unfamiliar audience (tourist) to that space, in the case that the short corridors show the current state of the palace for the audience with a passing glance and give him a general view of the palace. The longer the hallway is, the less the lines of sight are, and the attention is focused on the body of the hallway and the mind is involved in the analysis of the body and the spatial structure of the hallways, which multiply similar forms in the ceiling of the entrances leading to the mezzanine, the ceiling, and the vaults and details of the roof. Long-term Isovist view in the corridors, the direct connection between the states of the lines and the psychological states of the people, the parallel and parallel horizontal lines, even with the distance between them, with the help of the human eye, the principle of continuity, the straight and smooth line is understood and evoked. According to the prepared report and the software data about the angular analysis and the amount of rotation of the tourist in the environment, it was also proved to affect the understanding and readability. In all cases, direct paths have no direct relationship with the readability and appeal in the direction of attracting tourists. Why that the entrances that had a large rotation angle in the long corridors, the viewer is involved in the physical arrangement. The decorations protruding from the ceiling are effective in terms of depth and connection and the tourist's perspective and invite people to move in the space of the market. By being in the architectural space and seeing many layers in the horizontal and vertical view, the tourist will see different perspectives in the architectural space and will have a different understanding, this shows that the field of view alone is not enough to understand the environment.Conclusion:      In the study of three categories of houses (small, medium, large), it can be concluded that the length of the corridor, the model of the entrance (straight, broken or spiral), the location of the entrance (corner or middle of the longitudinal or transverse side), The shape of the yard (rectangular or square), the area of ​​the yard in the plan can have an effect on the field of view of the tourist. But the tourist field of view, Isovist view and angle analysis in all cases have no direct relationship with readability as one of the components of the physical quality of space. Manuscript profile
