Introduction
The environment can cause positive and negative emotions in citizens. Emotions are important due to their impacts on people’s behaviors, because emotions make up a main component of social behavior, and extraction of emotional responses is one of the best ways to understand different fields of experience and perception. Nowadays, mental health problems and the emphasis on increasing social interactions have led to more and more concern for the subject of emotions, but the impact of physical-spatial factors has received less attention from the conducted studies. The aim of this study is to investigate the effect of the physical-spatial measures of urban streets on pedestrians’ emotional responses by placing the individual in a pseudo-real environment. Moreover, this study makes possible the use of a new neural measurement tool in urban studies and evaluates its accuracy.
Theoretical Framework
The review of previous studies demonstrated that the environmental parameters that can affect emotion include non-physical human factors on the one hand and physical ones on the other. The physical factors that make up the subject of this research can be divided into two categories: 1- non-artificial factors, i.e. green space, and 2- artificial factors, which include the size and enclosure of the space, the shape and form of the space, the characteristics of the surfaces including architectural style, the color and texture of materials, and the variation in spatial sequences. Given the number of studies conducted on the effect of natural factors and certain characteristics of surfaces in the field of architecture, the present research examined four physical parameters.
Methodology
Ten of the most important physical-spatial variables that make up different states and types of the spatial structure of an urban street, which can affect the individual emotions of pedestrians, were selected for investigation and used to design 18 tests. The research was conducted with a combined method consisting of: 1- a self-report method of Self-Assessment Manikin (SAM) images and 2- a neurological method using electroencephalography. In the EEG method, the single-channel MindWave MW001 headset, produced by Neurosky, was used as the instrument. The research population included 50 students of Tarbiat Modares University. The research was conducted with the help of controlled experiments using the mobile digital 3D modeling technique, which makes it possible for people to navigate the virtual street in the city. After the data extracted by the health and Stroop tests were confirmed, the data analysis was made using a quantitative-statistical method.
Results and Discussion
The findings regarding the shape and form of the space demonstrated that people feel more pleased in curved streets than in straight streets, and there is greater arousal in streets of the former than the latter shape. However, the level of control in a straight street is higher than that in a curved or spiral street. As for the size and enclosure of the urban space, the results indicated that there is greater pleasure in a street with medium enclosure (1:2 and 1:1) than in one with low or high enclosure (1:4 and 1:1.2), but streets with medium enclosure exhibit less arousal. Spaces with less enclosure cause people to have more control over the space. The results also demonstrated that the pleasure and arousal experienced by people is increased by the existence of the square as a spatial element and a landmark building as a physical element, permeability in the spatial structure of the street and brokenness in the path, and variation in the landscape of the street. It was only in the street with physical retraction and protrusion that no effect on arousal was observed, although the level of pleasure should increase. Moreover, the results indicated that the pleasure in the street with the curved corner was greater than that with the other forms. However, the shape of the street corner exhibits no effect on the arousal. Furthermore, the walls that are completely three-dimensional exhibit greater pleasure and arousal than those featuring walls with two-dimensional and three-dimensional rhythms. Finally, the walls that are completely two-dimensional have the least pleasantness and arousal. There is a higher level of control in the street with 2D rhythms than in that with 3D rhythms. The results also showed that visual permeability in the physical structure of the street increases the arousal and control of the space, but it has no effect on the pleasure. Another result of this research is that there is 75% conformity in the results obtained from the two methods of SAM and EEG, which demonstrates that the data (EEG) extracted from the device can extract people’s emotions well.
Conclusion
In general, the current research confirms the results of previous studies, but it precisely demonstrated by measuring the extracted neural data that the levels of emotional pleasure, arousal, and control are affected by the shape and form of the street, the size and enclosure of the street space, the presence of a spatial and physical element that creates attention and emphasis in the street, permeability in the spatial structure of the street, rotation along the street and perspective change along the path, two and three-dimensional wall street rhythms, and the shape and form of the corners of the street intersection. However, physical indentations and protrusions exhibit no effect on arousal, and visual permeability has no effect on pleasure. In addition, the results showed that the EEG data extracted from the headset (MindWave MW001) used in this study could well capture the emotions of individuals, thus making up a proper potential tool for evaluation of environmental design interventions in the field of architecture and urban planning. The results of the present study, which indicate the psychological effects of urban design of a street, help to select and design the appropriate elements and physical characteristics of the space, increase positive emotions and reduce negative emotions, and ultimately improve the mental health of citizens.

Objectives Today, walking is one of the missing links in urban life. Thus, it is required to review the form and structure of today’s streets, which is a great concern for the urban experts and citizens. Therefore, it is crucial to consider urban pedestrians and find solutions to promote urban environmental quality of life and to promote citizens’ satisfaction with the environment. The city of Sareyn is not an exception. Given the climatic conditions of Sareyn and its high traffic, it cannot attract tourists and residents. These circumstances may pose an obstacle to the development of Sareyn in terms of tourism. Thus, constructing pedestrian walkways could facilitate the revitalization and development process of the city. As a result, this research aims to introduce significant factors in constructing pedestrian walkways in Sareyn, which will be a suitable background to guide the development process of the city. Findings This paper applies the path analysis method to determine the factors affecting the construction of pedestrian walkways in Sareyn. The results of regression analysis method for direct effects indicate that about 64% variance in pedestrian walkways is likely to be explained by research indicators. Variables of walkways and transportation, security, economic functions and urban services and facilities are more significant than other variables in predicting the dependent variable. The second and later stages of the path analysis method measures indirect effects. The results of these stages show that the effect of urban services and amenities on the construction of a pedestrian walkway is 46.3%, it is 11.4% for the transportation criterion, 11% for economic performance, 3% for the socio-cultural criterion and 18.1% for the security factor. Sum of the direct and indirect effects of the independent variables on constructing pedestrian walkways shows that the most effective factor in Sareyn city is related to “Walkways and Transportation” factors. Walkways and transportation affect the dependent variable directly by 0.362% and indirectly by 0.091%. Other effective factors in order of importance are security, urban services and facilities, economic, socio-cultural and geographic functions. Results Path analysis method was used to determine the effective factors on making pedestrian walkways in Sareyn, as a pole of tourism in Iran. Due to the multiplicity of factors, multiple regression test was performed. The direct effects were analyzed in the first step and then the indirect effects were calculated. In the first step, it was observed that research factors explained pedestrian walkway construction by 64%. The most significant factors in this stage were urban services and facilities, transportation, security, socio-cultural and economic functions. The most significant indirect factors were determined to be geographic factors with an indirect path and security with two indirect paths. There were 5 direct and 8 indirect paths in this research. Finally, the most important factors were walkways and transportation, followed by security, urban services and facilities, economic, socio-cultural, and geographic factors. The results show that the improvement of the above factors would make good conditions for constructing pedestrian walkways. Furthermore, the improvement of these factors would have a positive effect on the number of pedestrians using walkways. Finally, improvement of other factors would also have such effects.
