The period spanning middle of Qajar era to the first decade of Pahlavi is a part of Iran contemporary architecture which is influenced by inevitable alterations caused by modernity. Modern forms and figures have gradually changed spatial hierarchy of houses and their structure and consequently have led to a combinational style. A brief survey of spaces and chief elements of traditional houses of Sanandaj demonstrates these changes quite well. This paper tries to shed light on the prevalent style of spatial hierarchy of house entrances in transitional time period from tradition to modernity in Sanandaj. This research has been conducted using a theoretical approach and by a historical-interpretational method. In theoretical part, a qualitative approach is adopted and considering the literature history, effective factors on spatial quality evaluations are analyzed. The practical part of the research is carried out in two phases and by taking case studies under account. In this viewpoint, the theoretical part is firstly a brief appraisal of the architecture of the historical eras of Qajar and Pahlavi, evolution criteria and social revolutions of those periods as well. Moreover, assessment of houses based on historical periods has been done utilizing field studies, local survey, photography, house plan depicting and existing documents and plots. Secondly, based on acquired field and librarian information, all qualified houses for this research are compared and analyzed to attain a comprehensive understanding of their entrance spatial hierarchy. Findings of the research indicate that there has been a hierarchy in entrance of houses with traditional architecture pertinent to the needs of residents which is neglected to some extent by the designers in Pahlavi period. In conclusion it is admitted that by intermediate spaces, alongside the provision of confidentiality, it would be possible to achieve a proper definition of private and semi-private spaces in houses. Furthermore, disruption in functions and entities of other spaces could be avoided, which in turn leads to introducing a pattern for obtaining confidentiality; an inseparable principle of entity in Iranian architecture and culture.

This study analyzes the spatial variations of urban hierarchy of Kermanshah province in the period of 1996-2011. This study aimed to explain the uneven distribution of population and social inequality-to reduce the economic disparities across the province. Analysis indicates that 29 cities of Kermanshah in 2011, with a population of about 851, 405 people in the city of Kermanshah Province, 62.8% of the urban population, approximately 16 times and 8times the second and third cities of the same province (Kangavar) population has the most unevenly distributed population. In fact, the lack of central cities in metropolitan networks in urban areas has created instability. This analytic method utilizing GIS, EXCEL, the rank-size model of a class difference, Entropy Coefficient and Lorenz Curve has been done. Results of the entire hierarchy of methods used in urban imbalance and instability tends to show instabilities. Based on a floor equal to 96.6 percent in 2011, more than 141 thousands of people in equations obtained from the following cities ranked as the cities of Kermanshah show much difference between the three periods and the line of normality. The entropy rate of 75 year /8to / 79 in 85 and in year 2011, /69 which indicates heterogeneity in the distribution of population was reached. The city of Kermanshah in terms of spatial distribution of population is the worst compared to other cities, so that, the first city (Kermanshah) has 216 times more population compared to the second city (Kvzran).

Balanced planning necessitates a harmonious national and regional planning as well as a specific and relevant project for a given region under the whole system of national order. This is particularly even more necessary in the third world countries such as Iran. In Iran the growth of economy based on capitalism, land reform, concentration of social and economic investment in major cities particularly in Tehran metropolis, has brought about several irregularities in the national and regional level. Unbalanced distribution of facilities and various services and their concentration in large urban centers have been the characteristics of this irregularity. In This study the hierarchy of settlement of Hashtrud Township has been examined and analyzed in terms of its demographic functional and developmental planning.Research methodology employed is descriptive-analytical and quantitative models and relevant computer software has been made use. Conducted researches in the township level of Hashtrud suggest that firstly, due to the lack of living facilities such as health and educational and welfare services the population of villages declines steadily and some of its are vacated, and in rural phenomenon of migration occurs area than a large number of ruralareas of Hashtrud township lack the proper spatial order in terms of population distribution. Secondly, the township centre (Hashtrud city) also has been unable to offer optimism services to it hinterland due to the poor financial facilities and technical equipments. This has led to irregularities in the spatial order of the township.

Introduction Cities accept different roles and functions based on their characteristics with different power and influences. More attention is paid to some cities. This leads to reduction of the importance of other cities and finally, this leads to development of urban primacy phenomenon. Urban hierarchy as one of important subjects in urban studies includes several topics such as stair system of urban hierarchy. Along with development of urban primacy in this system, a kind of internal order is developed among the cities and a hierarchical system is created. These groups are formed via population gap on a linear curve. This urban hierarchy system is faced with some questions on the relationship between spatial pattern of urban groups, pervasiveness of the stair system, the number of cities, the number of urban population, the urban primacy coefficient and the number of urban groups. This paper investigates these issues in Iranian urban hierarchical system. Methodology The present article is conducted via descriptive analytical method with documentary and library studies. In order to answer the research questions, first of all the status of the cities in urban hierarchy was examined using rank-size model and then the stair system in national and regional scale. In the next phase, spatial dispersion of the cities was displayed using the GIS to investigate the relationship among the cities in a group and their spatial dispersal. Census studies were also carried out by Iran's Statistical Center in 2010. Finally, the aim of this research is based on spatial distribution analysis of cities in stair system of urban hierarchy, the average of nearest neighborhood, multi-distance spatial cluster analysis and standard deviational ellipse methods. At the end of the research, Spearman test was used to understand the relationship between the numbers of urban population with the number of groups in the stair system. The statistical population of the present study is all the cities of the country at national and regional scale. Out of 30 provinces, 10 provinces were studied as the research sample. Results and discussion Findings showed that different regions of Iran are very different in terms of the number of cities and population. Among them, Khorasan Razavi province has the greatest number of cities (72 cities) and Yazd Province has the lowest number of cities. In terms of population, the urban population in different regions has fluctuated from 800 thousands to more than 11 million people; as Tehran and Khorasan Razavi have had the highest number of population and Hormozgan and Yazd have had the lowest number of population in the sample. On the other hand, based on the studies, West Azerbaijan with 9 groups and Chaharmahal-o-bakhtyari with 5 groups, have been ranked as the first and the last of urban groups in regional scale, respectively. It is interesting that the lowest number of urban groups is seen in the national scale. Based on the above mentioned cases, urban system in Iran at both national and regional level is faced with stair system of urban hierarchy. This characteristic comes from the urban primacy. On the other hand, the group-mate cities in this system, not only are not in the same area, but also they are dispersed in the region without any specified pattern. Group-mate cities don’ t create isochromatic zones in the region based on urban groups' dispersion map. Accordingly, it is not possible to determine a border for group-mate cities. Therefore, cities contrary to the stair system on the diagram don’ t follow any order geographically. There are significant differences in this field between urban groups. Most important of them are stair system is not visible in low population urban groups in some regions (Yazd and Mazandaran). In some regions urban groups have very low members (2-3 members), some regions in terms of the number of groups and city frequency are in balance and the provincial capitals are the most regular. Results show that there is no relation between dependent variables including number of cities, number of urban population, urban primacy coefficient) and independent variables, number of urban groups. This means that the increase or decrease in the dependent variables have no effect on the number of city groups as independent variable. Conclusion Investigation about urban network of Iran in both national and regional level shows that there is no harmony with rank-size model in urban hierarchy. This indicates undesired relations between cities. Thus, urban primacy is a dominated phenomenon in Iranian urban system. However, this phenomenon appears in different patterns named as stair hierarchy. Study of urban system in Iran confirms the existence of stair system in urban hierarchy at both national and regional levels. This system divides the urban hierarchy into several urban groups. The group-mate cities are separated from upper and lower level cities due to the population gap. It seems that they make a new form of urban hierarchy. In this system, the cities could be classified into several groups and each of them developed more homogenous hierarchy system compared with the whole urban system in the region. One of the most important issues in this area is identification of the main factors, because the variables have been studied in this research are not the main factors in the development of the stair system. Study of this system and mechanism of its function can lead to the identification of new dimensions of urban hierarchy system at the other scales. This research can achieve better results, provided that it is done as a comparative study at different scales ranging from regional, trans-regional and international scales.

Undoubtedly, privacy with the tool of spatial hierarchy has been one of the main criteria for designing and building Islamic cities. Islam's emphasis on privacy has caused this characteristic to affect all social and cultural aspects of which architecture is one of its manifestations. The architecture of buildings is designed to respond to the cultural and environmental needs of people. Since the model of the contemporary houses of Kermanshah is to some extent proof of the disregard for the principle of privacy in Iranian architecture and culture, providing a model for maintaining privacy in modern houses based on the typology of housing seems to be one of the necessities. This research aims to know the spatial hierarchy in creating privacy in the historical typology of houses. By investigating the spatial hierarchy in creating privacy, the evolution of these spaces in the houses of three eras was investigated. The research method is descriptive-analytical, with an emphasis on logical reasoning. The research findings show that in the historical houses (traditional and transition period) of Kermanshah, the hierarchy in entering the house has been proportional to the needs of the residents, and this proportionality is less in the priority of attention of today's designers. Therefore, by creating a hierarchy in the entrance space, in addition to creating privacy, it is possible to achieve a proper definition of private and semi-private spaces in contemporary (modern) houses and to prevent disruption in the use and identity of other spaces.

Decision making about choosing appropriate locations for groundwater dam construction by considering the various criteria that must be considered in the selection, is difficult. These criteria include technical, environmental, economic and social standards. Using Analytic Hierarchical Process (AHP) due to the possibility of considering various qualitative and quantitative criteria can be one way to select the appropriate location for constructing the underground dam. In This study, the spatial and non-spatial Analytic Hierarchical Process (AHP) was used and with regard to assessment criteria, five convenient locations for constructing an underground dam in the area of Pishkuh catchment's in Taft's township of Yazd province were prioritized. At the end with defining five scenarios these places were prioritized in which due to the property of some of the criteria, sub-criteria and evaluation indicators, the results of prioritizing two spatial and non-spatial methods were not the same.

The issue of privacy has always been regarded as an essential criterion in designing and constructing Islamic cities. Since the existing pattern of house-building in Tehran tends to neglect the privacy principle, there exists a necessity to reintroduce it in modern Iranian architecture and culture. The present study aims at investigating the issue of privacy in houses located within traditional parts of Tehran via analyzing typology. This would help the residents of those areas to renew and reapply the privacy principle at their residential apartments. In the present study a functional approach was adopted accompanied by a descriptive-analytical method of analysis. Using maps and field observations, houses from both traditional and modern era were selected in two quarters of Sanglaj and Imamzadeh Yahya in Tehran. The process of typology of entrance spaces was conducted based on the hierarchy of entry. The research findings indicate that there exists a kind of hierarchy of entrance in traditional houses based on the needs of their residents which is missing in modern houses, because it is neglected by the designers. Through creating such spatial features in entrance spaces, not only privacy is enhanced but also a proper definition of private and semi-private spaces can be achieved. Privacy enhancement will be effective to prevent the interruption in functions of other spaces. Accordingly, recognizing the spaces of entry can lead to providing a more appropriate pattern for enhancing privacy.

A B S T R A C TThe right to the city in urban development goes beyond the physical form and, at the same time, has a mental and social meaning, which has been popularized in planning theory and urban studies after its proposal by Lefebvre. This theory focuses on the residents and the distinctive features of the space and believes that the right to the city can only be formulated as the right to the evolved and renewed urban life. Based on descriptive-explanatory purpose, this research seeks to spatially analyze the components of right to the city in Bandar Abbas. Therefore, after collecting 77 subjective and objective measures around the research components, the multi-criteria decision-making technique of COPRAS has been exploited to integrate the data in the ArcMap Tools. The findings show that in the current state of urban development in Bandar Abbas, the right to the city in all its aspects, the right to ownership, the right to participation and the right to difference for the residents have been weakened and ignored. A share of up to 20.7% of the city space, which is mainly directed to the wealthy neighborhoods and parts of the central areas of the city, as well as parts of new developments, the right to the city has been more manifested, and in about 19.8% of the city spaces. Mainly applicable to informal settlements and slums of the city, this right has been undermined and ignoredExtended AbstractIntroductionThe right to the city as a physical, mental and social concept seeks a fundamental change in dealing with urban planning and development issues, which has been popularized in planning theory and urban studies after its proposal by Lefebvre. This theory focuses on the residents and the distinctive features of the space and believes that the right to the city can only be formulated as the right to the evolved and renewed urban life. In other words, this theory is a call for the priority of the consumption value of the city against its exchange value, which can only be pursued through the analysis of urban issues in the framework of the "city space" metaphor in the right to the city. It is a fundamental change in the city to create opportunities and space for citizens to meet and achieve their needs. MethodologyFrom a descriptive-explanatory purpose, this research seeks to spatially analyze the explanatory components of urban development in Bandar Abbas from the perspective of the right to the city. In this research, by collecting 77 subjective and objective measures, the COPRAS multi-criteria decision-making technique has been used to integrate data in the ArcMap environment. Citizens are the source of mental data, official documents and maps are the objective data, and experts are the relative weight of the criteria. It should be mentioned that to guarantee the validity of the content based on the guidance of supervisors and advisors, the collective opinion of university experts and the use of similar studies were exerted. The reliability of the questionnaire was also tested by Cronbach's alpha method, and the value of the alpha coefficient (0.866) indicates the high reliability of the questionnaire. Results and discussionThe findings show that in the current state of urban development in Bandar Abbas, the right to the city in all its aspects, including the right to possession, the right to participation, and the right to difference for the residents, has been weakened and ignored. A review of the findings shows that the social function of the city's real estate and land, with a coefficient of 0.136, followed by environmental justice, with a coefficient of 0.131, has the greatest impact on the urban development of Bandar Abbas. On the other hand, socio-spatial justice in the process of taking over space, with a coefficient of 0.106, shows the lowest level of influence in the development of Bandar Abbas compared to other components of the right to the city. The results show that about 20% of the area of Bandar Abbas city is in a very unfavorable situation compared to the components of urban development based on the right to the city approach. These areas of the city are spaces where the residents' right to the city has been severely denied, and they are deprived of taking over the city space.In this regard, the results show that 20.7% of the city's space, mainly focused on wealthy neighborhoods, parts of the city's central areas, and parts of Mehr's housing, has the right to a greater manifestation of the city. The city's space is more in line with its residents. As shown in the spatial distribution of the urban development components of Bandar Abbas based on the right to the city approach, the possession of space through the right to presence, the accessibility of residents to the opportunities and resources of the city, as well as the fair distribution of facilities and services play a decisive role in urban development. However, as the results show, it is the difference that gives meaning to the urban space, and therefore the space must provide the conditions for the city to play a role in meeting the needs of all city groups. The requirement of this role is the central position of the residents in making decisions about the city space, which is a unique way to realize the right to the city. ConclusionAs Brenner states, the right to the city is a call to create "cities for people, not for profit." In this definition, urban development is more than a physical thing and has a mental and social dimension at the same time. In terms of the right to the city, the right to possession, the right to participation, and the right to difference form the trinity of urban development and the guiding light of these three principles that determine the quality of a different city. Unfortunately, urban development in Bandar Abbas has weakened and denied residents' rights. The zoning resulting from the spatial analysis shows that about 19.8% of the city's spaces, which mainly correspond to informal settlements and poor neighborhoods, this right has been weakened and ignored. From the theoretical aspect of the right to the city, this event originates from the space as an economic and physical thing exchanged in the market, not a consumption thing formed by the citizens and in social interaction with the space. FundingThere is no funding support. Authors’ ContributionAuthors contributed equally to the conceptualization and writing of the article.

The development of motor vehicle use has reduced irreversible fossil fuels, environmental pollution, and reduced physical mobility, despite significant reductions in travel times, especially over long distances. On the other hand, this saving is not achieved during peak hours, especially at short travel distances. One way to solve this problem, especially in metropolises that face more environmental challenges, is to develop intercity transportation for short distances by bicycle. The purpose of this research is to select the optimal safe bicycle route in District 10 of Mashhad Metropolitan Municipality due to the modernity of the area, high traffic load, and at the same time having the capacity to develop bicycle-based transportation. The research method in this paper is descriptive-analytical and based on Analytic Hierarchy Process (AHP). The method is to collect documentary and field information. Multi-criteria analysis of indicators in this research has been done by expert choice software in digital mapping layers and simulated in GIS environment. The input of this model will be the information and documents examined by the target environment and its output will be maps that show the potential of the area's roads to be used as a safe bicycle route. The findings of this study showed that the safety index of intersections and the type of passages with 27% had the highest impact factor and the index of distance to bus stations with an impact factor of 2% had the lowest coefficient of importance. Therefore, it can be concluded that Shahid Rasti Street and Andisheh Boulevard, after Shahed and Shahed Boulevards intersections, have the greatest potential for safe cycling, respectively.
