&nbsp;In recent years, as the size of displays have become larger, the number of installed outdoor street vision around station intersections have increased year by year. However, there are not sufficient rules to regulate outdoor street vision. Besides, there are no previous studies that have quantitatively examined the causal relationship between physical environmental factors and psychological evaluation of the landscape with outdoor street vision. It is necessary to quantitatively consider the relationship between the physical environmental factors of outdoor street vision and human reactions. In addition, it is necessary to demonstrate concrete guidelines in order to maintain an attractive landscape. Therefore, landscape simulation experiments were conducted using a 1:100 model, in which physical environmental factors such as the number of installed street vision and its size were changed. Subsequently, based on the obtained data, the factors that prescribe landscape evaluation are quantitatively examined.<br><br>&nbsp;As a result of clarifying the factors that regulate landscape evaluation around the intersection of a station with outdoor street vision, the following three points were observed.<br><br>&nbsp;1) Landscape evaluation around station intersections was strongly influenced by outdoor advertisements. Furthermore, it was confirmed that the influence of outdoor street vision is stronger than those of wall advertisements and rooftop advertisement towers.<br><br>&nbsp;2) As a result of evaluating the landscape around the intersection in front of a station, it was confirmed that the feeling of bustle and sense of brightness increase in proportion to the size of the advertisements. Consequently, it was confirmed that the sense of cohesion and comfort decreased in inverse proportion to size of the advertisements. In addition, the bustle and brightness feelings increase when the installation ratio of the outdoor street vision is high, while the sense of cohesiveness and comfort are increased when the installation ratio of the outdoor street vision is low.<br><br>&nbsp;3) In the vicinity of the intersection in front of the station, the comfortable feeling is maximum with the installation ratio of the street vision of 2%. It would be better if there was no street vision than there was not. The installation ratio 5% to 5.5% is an equilibrium point that satisfies 4 scales. When this level is exceeded, the downside is conspicuous in terms of cohesiveness and comfort. It is the limit of the allowable range with the installation ratio of 8%.<br>&nbsp;Based on the above findings, a landscape formation index around the station crossing is described. The upper limit of the percentage of street vision to be installed should be 5% to 5.5%, which is the equilibrium point. It is reasonable to set the allowable range to 8% or less.
