The factors and criteria effective on users’ sense of security were extracted using exploratory factor analysis.
Introduction
One of the most important components of environmental quality, environmental security plays an important role in the use of urban spaces. In fact, the feeling of fear and lack of security in urban environments, including parks, has turned into a problem in today’s societies. Parks are areas in cities where any citizen can spend their leisure time and enjoy park-based recreational activities. Many factors affecting the security of urban parks can be attributed to their design and physical conditions. Therefore, it is necessary to identify these factors and provide appropriate solutions to improve their conditions. Since an urban park needs a conscious design that provides the users’ satisfaction, it is necessary to consider their characteristics, which can be achieved through their participation.
Theoretical Framework
To explain the theoretical concept of security, two distinct dimensions are mentioned. The first is the objective dimension, which is evaluated using objective environmental and behavioral parameters, and the second is the mental dimension, which is understood based on the security of the community. Both dimensions can have a positive or negative effect on the other. Therefore, it is necessary to consider the two dimensions together in order to improve public security.
Methodology
Since a comprehensive questionnaire was not found to measure the security of urban parks based on users’ preferences, a researcher-made questionnaire was prepared, and its validity and reliability were verified. The research method was qualitative and qualitative-quantitative. In the first step, the qualitative research method was used based on content analysis, and the questions of the open-ended questionnaire were implemented in textual form based on the contents of the experts’ statements. The components were obtained from content analyses of users’ responses to the semi-structured open-ended questionnaire, and the closed-ended questionnaire was developed on that basis. The final questionnaire was designed as a closed-ended one to quantify the variables faster and be capable of running on a larger scale. The questions had the structure of a four-point Likert scale, with the answers ranging from strong disagreement to strong agreement. The questionnaire was distributed among 250 visitors of Mellat Park, Tehran. Since the differences in the environmental, socio-economic, and physical characteristics of different places can give different senses of security or fear to citizens, a major park in Tehran (Mellat Park) was chosen for a case study. It extends over an area of about 34 hectares in Municipal District 3. The purpose of this study was to construct, normalize, and validate a security scale for urban parks from the users’ perspective.
Results and Discussion
Content validity was verified through preliminary implementation, open interviews with users, and expert approval. In the preliminary step, reliability was measured using the internal coordination of the questions with Cronbach’s alpha. The final questionnaire was distributed among 250 park visitors. The results indicated that the questionnaire was valid and standard, and eight explanatory factors were obtained from the users’ preferences as the data obtained in SPSS 22 were analyzed using the exploratory factor analysis technique. These included artificial element design, control and surveillance, plant design, readability, physical accessibility, aesthetics, activity patterns, and space size and extent. From the users’ point of view, artificial element design was the most significant factor, followed by control and surveillance, plant design, readability, and physical accessibility, and aesthetics, activity patterns, and space size and extent were ranked next.
Conclusion
Understanding users’ perceptions of landscape design methods and considering their preferences and desires helps landscape designers with their jobs. It can be considered as a topic for future research how each of the obtained components can induce a feeling of fear or security in urban park users. Examples include specification of the relationship between vegetation or readability and the feeling of fear or the standard for each of the service elements, pieces of furniture, etc. Through presentation of a model, the hidden relationships between factors can be achieved, and a theoretical pattern composed of many different components can be examined both entirely and partially. Of course, it should be noted that none of these factors alone induces fear or security; rather, there are a number of factors that contribute to a complex interaction, such as personal characteristics (age, gender, etc.) and social characteristics (familiarity with the environment, solitary presence, frequency of presence, etc.), which can be investigated in future research.

The public spaces of city shape social flows, provide the material needs of citizens, their intrinsic need for communication and face-to-face social interactions. Therefore, the quality of urban spaces in the formation of social interactions, the mental image of the city and its visualization are important. Several factors play a role in the formulation of the concept of quality, the most important of which is the configuration of urban spaces. The spatial configuration organizes the relationships between urban spaces. It is a factor in shaping qualitative variables such as readability and accessibility. Parks are one of the urban spaces whose social performance and productivity are directly affected by spatial quality. However, urban parks are now the epicenter of most social anomalies due to different factors and, as public spaces, are less able to provide a suitable environment for the formation of social interactions. In recent decades, the theory of space layout has made it possible to analyze the spatial configuration and its relationship with social, economic and physical factors using spatial variables.The present study investigates the structure and analyzes the features of spatial configuration of Mashhad in order to examine its effects on the spatial quality of urban parks. Configuration analysis provides an appropriate assessment of the spatial distribution, accessibility, security and readability of urban parks and can play an important role in redefining the quality of urban parks spatially. Since parks play an important role in urban spaces, evaluation of the layout, spatial distribution and access to urban parks in Mashhad are among the most important goals of the study. In addition, the readability and security of Mashhad parks are other parameters that are studied in this study using the space-layout theory variables. The present research is an applied research with a descriptive-analytical method. The statistical sample involves 290 parks in Mashhad in the five categories of neighborhood, local, district, region, and city. The research was conducted using spatial variables of space layout. The theoretical framework of the research was developed based on documentary and library studies with the aim of explaining the dimensions of spatial quality. Also, the city’s statistics in 2014, land use maps of 2011 (1/200 scale), satellite images and field surveys were used to analyze the data and collect information about the urban parks in Mashhad. The analyses were conducted in the GIS environment and 10 UCL Depthmap based on Mashhad’s axial map. The basic variables in this study were connectivity, interconnection, and control. The intermediate variables were readability, accessibility, space security, and cohesion. Research results show that despite the large dispersion of parks in the city, there is a spatial logic between the performance of parks and the city’s configuration. While regional parks are expected to be more readable in the structure and configuration of the city of Mashhad than district parks, the analyses show that they are less visible and accessible than other parks. The spatial distribution of these parks and their placement in spaces with a greater depth has decreased their spatial quality. Thus, one cannot expect significant functional and social effectiveness from this category of parks. In terms of spatial quality, urban parks are perhaps the only form of urban and social spaces that have the greatest impact on the spatial configuration of city due to their type of performance. The results of this study show that the distribution of urban parks in Mashhad is less spatially hierarchical. Although the main parks are distributed on a city scale in accordance with the axes of association and readability, most regional and district parks do not have such a distribution. This feature also affects the spatial cohesion of urban parks in relation to the structure of Mashhad and reduces the quality of space. Finally, it can be of said that, regardless of the spatial cohesion of Mashhad, which has a weak correlation with the components of the urban space and the city as whole, all the research indicators related to the quality of parks in Mashhad are poor and weak. This necessitates the attention to the park’s functional scale in the planning process, the proper location of urban parks, and the proper design according to the urban spatial pattern. Also, an assessment of the category of parks found that despite the number of neighborhood and local parks, these types of parks are better in terms of control than other parks, which seem to be logical according to the functional radius on a local scale. However, urban parks are of great importance in terms of accessibility and readability in the current structure of Mashhad. It seems that the assessment of spatial quality and its relationship with function can have an effective role in the planning and design of urban parks.
