The main perspective of this research is to investigate the existing potential of Mashhad to become tourist-friendly and the capabilities of Mashhad to become a tourist-friendly city as a new topic. For this purpose, efforts are being made to systematically compile the indicators of the tourist-friendly city according to the existing cultural and pilgrimage potentials of Mashhad. Behavioral patterns of tourists are analyzed in the form of statistical and spatial databases. The results showed that in all 19 field sampling points, on average, about 65% of tourists' responses to the directional questions raised (with the topic of the tourist-friendly city) were negative. Among the studied parameters, the parameters related to the spatial components have not been satisfied and approved by the tourists. The parameters studied in the research were analyzed and weighted by the hierarchical analysis process of AHP and used to overlap the layers of spatial maps and the final zoning in GIS. The results of our study showed that the highest satisfaction of tourists was recorded in the central area of Mashhad and around the shrine, which shows the characteristics of religious tourism in Mashhad. Considering the facilities and limitations of Mashhad city from the perspective of the research topic, the appropriate strategies for production and formulation, and the obtained results showed that the policy of strengthening and expanding service and welfare uses is important and preferable and a higher priority for the realization of the research topic in Mashhad city.

The purpose of this article is lotting the mine hazardous and determining the dangerous zone next to the minefields by means of Remote Sensing and GIS techniques.

In this article four factors are considered such as; Altitude, gradient, The distance from waterway network and soil erosion factor (the result of RUSLE-mode) 7 location map for lotting mine hazardous for under study zone was created by means of fuzzy overlap of gamma operators type 0, 0.25, 0.5, 0.625, 0.75 and 0.875.

The results of the research showed a high correlation between the location map of lotting mine hazardous with different gamma powers (except gamma 1) and height and soil erosion factors in sequence.In the location map resulting from the fuzzy overlap with gamma 1, this high correlation relationship was created with erosion and gradient factors in sequence When the gamma power is equal to 1, most of the areas are introduced as high-risk class, which means that it has been negligent in introducing the lots as high-risk zones. On the contrary, as the value of gamma power decreases, the area of the high-risk class decreases and the area of the high-risk, medium-risk, low-risk, and very low-risk classes increases in sequence. and in fact in introducing the zones as high risk lots is act strictly.

In all the location maps created, low altitude areas and waterways are placed in high-risk and very high-risk classes, which shows that these areas should be prioritized for demining.

Environmental factors play an effective role in creating human settlements in any time period. Sarakhs Basin in the northeast of Khorasan Razavi province is one of the regions of Iran that due to the lack of archaeological research on its biological and cultural landscape, many ambiguities and questions are raised. In the last fifty years, this area has been studied by various delegations, and several Bronze Age sites have been identified in this area. In this study, the main question is what are the most important environmental factors in the formation of bronze settlements in this area? In this research, 8 identified areas belonging to the third and second millennium BC of this area have been studied by descriptive-analytical method, using Arc GIS software, in relation to natural variables. The analysis of the findings has shown that this area in the Bronze Age includes settlements that have been subject to watercourses and other geographical factors such as terraces and clay sediments. In the Bronze Age, we see permanent and temporary settlements in this area, so that settlements with few deposits have been created near the water sources of waterways. These areas are often located in low altitudes and in the Bronze Age, the livelihood of this area, according to the elevation measurement of Bronze Age areas and soil type analysis, this area was probably based on livestock and agriculture was limited.

The effect of weather and climate conditions on road accidents has attracted considerable attention in recent years. This research aimed to analyze climatic parameters, including wind speed, dust storms, fog, and hail, using the GIS technique. Station data used for this study were from Amirieh, Bastam, Foroomad, Qaleh Now-e Kharaqan, Hosseinian, Kohan, Mehdishahr, Majen, and Nardin in Semnan province. Following that, accidents on the main roads of Semnan-Shahrud and Mayamey-Jajarm over six years (2016-2021) were examined. Maps were produced regarding accident risk for each meteorological parameter on the mentioned roads using ArcGIS 10.3 software, divided into five situations: very low, low, medium, high, and very high. A comparison was made between Kriging and IDW as interpolation methods. According to the findings, most accidents happen on both roads in April. Also, on both roads, most accidents happen during the day, followed by lighting at night in all years. The results showed that the most serious accidents occurred on Semnan-Shahrood and Mayamey-Jajarm roads during clear weather conditions between 2016 and 2021. Furthermore, rainy conditions are ranked second regarding the risk of accidents on both roads during the years mentioned. The findings showed that the level of accident risk for the climatic parameters of thunderstorms and temperature was reported as low to medium and very low, respectively, on the Semnan-Shahrood road. Also, the risk level for precipitation and snow depth parameters was assessed as low to moderate. Further, the level of accident risk for the climatic parameters of snow depth, temperature, thunderstorm, and precipitation was evaluated as low to high, low, medium, and low to medium on the Mayamey-Jajarm road.

According to the findings, the level of accident risk for the climatic parameters of fog and dust storms is very low to moderate on the Mayamey-Jajarm road. Also, the level of risk for wind speed and hail parameters was assessed as low to high and low to medium, respectively.

Informal housing is a common style of urban growth in most developing countries and is organized somehow which is neither urban nor rural. This study aimed to understand the daily life experience of citizens in the suburbs of Hoveyzeh city in Khuzestan province. The research method in this research was based on the qualitative method in the form of data theory and the data collection technique was semi-structured interviews and participatory field observations. To achieve the research objectives, 20 residents of these areas have been purposefully selected. Interviews continued until the saturation of data. After coding, 21 main categories of data emerged, each of which was analyzed based on the text of the interviews. In terms of conditions including (lack of support and skills, disregard for spatial justice, the need to change the space for social change, sense of abandonment, direct experience of war, actors' mental contexts, historical criticism of the produced space, marginalized lifestyle, acceptance and normal Marginal life, destiny and heredity, local dependence on interests and connections, combination of fear and narrative) and in the action-interaction dimension (confrontation, conflict, comparison, feeling of despair in changing the situation, the blind cycle of poverty) and in Then there are the consequences (marginalization of the marginalized, the principles of the right to the city as a missing link, the combination of fear and narrative, self-reliance) that have formed around a core category called (bio-luxury and return to habit). Finally, after extracting the findings, using the GIS, the relationship between location and the incidence of injuries is discussed and the results are expressed analytically and graphically. Also, the results of the spatial analysis show that among the vulnerability components, most of Hoveyzeh's areas are exposed to security and psychological vulnerabilities.

Today, the importance of passive defense, especially location, is more apparent than ever. The location of military bases and barracks within the urban context, along with the horizontal expansion of cities, has created many problems in the missions assigned to the barracks and reduced its efficiency, which poses a serious threat to the proper execution of missions. In this regard, location selection studies as one of the requirements of passive defense in order to select a point with a high coefficient of spatial security is one of the key elements in the success and survival of these centers. Considering the location of the 216th Mechanized-Armored Independent Brigade in the urban area of ​​Zanjan and the need to transfer it to development programs, this study seeks to find a suitable and optimal location for this military barracks in Zanjan. The present study is descriptive-analytical; Using geographic information system and hierarchical analysis model, the necessary information was collected and analyzed. After determining the effective criteria for location in the GIS environment, suitable zones for creating a garrison were determined, and finally, using the weighted linear method, 6 suitable areas were determined as the best points for locating the garrison.

Criminal acts are located in crime hotspots, which is a place with a high rate of crime. The occurrence of crime in one place produces an apparent map that shows the spatial distribution of crime. Therefore, the main purpose of this study was to study the geographical centers of drug-related crimes in terms of causes and spatial distribution.

The statistical population of the study is the case of prisoners of Sepidar prison in Ahvaz who committed a total of 300 drug-related crimes in 2015. Geographic information system models and tools were used to analyze the data and generate a map of drug crimes in Ahvaz.

The highest incidence of drug-related crimes is in the central, western and southwestern areas and in the last areas of Asphalt, Khashayar, Hasirabad, Ein Do, Kemplo and Goldasht.

The results showed that the main centers of drug crimes in Hasirabad, water source, 20 meters and Asiabad from region 7, Khashayar and Kemplo, Lashkar and Sholangabad from region 6, the end of asphalt from region 1 with cluster pattern They are distributed. Glass, opium and heroin had the highest rates of drug crimes. The average center of total crimes corresponds to the city center and the ellipse is the standard deviation of all drug-related crimes with scattering and spread in the central part and stretching to the northeast, west and southwest.

Unemployment has a high potential for creating crises socially and politically, and thus it can call into question the state’s acceptability and legitimacy. The state’s response to unemployment is to delay the entrance of the new labor force into the job market by providing educational opportunities, which has led to an increase in unemployment among educated people in Iran. An spatial difference in unemployment and share of unemployed educated people in the country, a chronic spatial discrimination and domination of the core-periphery pattern and its adaption on the habitat of ethnic groups increase political concerns and the chance of rising unrests in Iran. This article uses descriptive-analytical and statistical methods with an emphasis on the discovery of spatial patterns of unemployment in general and unemployment of educated people in particular. The paper applies the methods of spatial analysis of Moran and Getis – Ord Gi * statistics to address the question on unemployment patterns in Iran and their effect on the country's political geography. The results show that the spatial patterns of unemployment are different from those related to the unemployment of educated people, and the sustainability of these patterns over time has strengthened the uneven processes of migration and development leading to the people's perceiving these as political. The continuation of this situation from a political geography perspective is a major challenge for the state and government.

The increasing urban development in Iran has caused many social, economic, and environmental problems. Among the social issues in cities, especially metropolitan areas, is the spread of crime and the formation of insecure spaces in the city. When urban spaces create a sense of fear and insecurity in people, they become defenseless spaces. That is, spaces in which a person feels the presence may be attacked or something unpleasant happens to him. In other words, such spaces, for whatever reason, could induce fear in people. These spaces are the product of a complex interaction in which the lack of symbolic and real barriers, the absence of the definition of specific areas and monitoring facilities, including natural-social and physical supervision, have made the rate of crime and social harms significant. Therefore, the identification of such spaces is necessary to take preventive measures and reduce the occurrence of crimes.  

The purpose of this study is to identify, analyze, and rank the risk of defenseless spaces in District 3 of Ardabil city. The present research is of applied-developmental type and its research method is descriptive-analytical based on graphic methods. In order to collect the required information, first, a library method was used. Also, the field harvesting method was used to identify defenseless spaces in District 3 of Ardabil city. To perform the analysis, criteria such as the frequency of defenseless spaces, population and building density, income groups, the quality of the road network, the physical quality of the texture, social characteristics, land and building prices, and land use were used. In the next step, data related to the main criteria of the research on surface complication (area zoning) were entered and the analysis was based on spatial statistics in GIS. Finally, after determining the effective parameters in the analysis of urban defense spaces in the form of pairwise comparison of the hierarchical analysis process, the weight of each research criterion was calculated according to the opinion of experts (30 experts including professors and experts in universities, research centers and offices such as Municipalities, law enforcement research offices, and experts in the field of urban planning). Then, after preparing the standard maps, creating a distance map from them, standardizing and reclassifying each of the maps, the layers were superimposed using the weight overlap index.  

Based on the map prepared using the kernel method, neighborhoods No. 3, 4, 6, and 9 had the highest density of defenseless spaces and thus are in a state of danger and vulnerability in terms of the existence of defenseless spaces. These neighborhoods are most densely populated. Calculations made using the nearest neighborhood mean tool indicated that urban defenseless spaces were distributed, clustered, and unbalanced throughout the region. According to the above results, certain areas are the focus of defenseless spaces under study and follow the centralized pattern; in contrast, parts of the area surface are considered as clean areas in terms of the existence of such spaces. The result of implementing the AHP model in GIS showed that 45.35% of the neighborhoods are at high and very high risk in terms of the existence of defenseless spaces. These neighborhoods are among those with informal settlements and middle neighborhoods of the city whose condition of the road network and the quality of their texture are not suitable. They have a high population density and the land use in this area is not compatible. These areas have the potential to spread social harm and delinquency. Also, poor monitoring, visibility, solitude and darkness, confusion, and burnout are the most important elements of urban space defense.  The present study can pave the way for other studies such as the study of crime in the city by types of crimes, the effect of environmental variables on crime, urban crimes based on type of urban context, and other related issues. Based on the findings, the following suggestions can be considered in managing and reducing the vulnerability of neighborhoods:1) Preparing a comprehensive crime plan.  This can help and guide the security forces. In this regard, GIS is very important. 2) Regenerating worn out urban texture that often forms criminal areas. 3) Determining the status of ruined buildings (cleaning or reconstruction) in the area, the number of which is not small. 4) Establishing or combining centers with long hours of work time (even 24 hours a day) 5) Locating and constructing law enforcement centers even in the form of smaller units in vulnerable areas. 6) Installing CCTV cameras in crowded spaces and announcing its existence along with controlng the space by using signs while observing aesthetic principles (with priority on installation in vulnerable areas). 7) Updating and accurately recording computer information about the place and time of crimes.

During the last two decades, the geographical analysis of delinquency and attempting to identify the spatial factors of social anomalies have been important using the GIS and statistical and graphical techniques for coping and preventing police and police administration. The identification of environmental and spatial factors of the crime and trying to eliminate these factors or reduce its effects is known as the most important preventive method for the occurrence of abnormalities. Spatial-temporal analysis is two important dimensions of criminal events. This kind of analysis provides valuable information for solving problems and responding to security and law enforcement problems. The present study was conducted with the aim of analyzing the spatial and temporal patterns of theft of crime in the area of ​​Municipality of Zone 2 and the area of ​​police control of Tabriz Metropolis. The purpose of this study is to use a descriptive, comparative, and analytical method. For statistical analysis and graphic data of delinquency data, GIS software, which is implemented under the name of Geographical Analysis of Crime by Naja in police stations, has been used. The statistical population of this research is the collection of robbery crimes that occurred during the period of research in the studied area. The research findings show that spatial and temporal spatial patterns proposed by the system are consistent with real and field patterns, and the geographic analysis system of crime has the necessary efficiency in analyzing patterns and identifying massive corpora.

Over time, criminologists discovered that certain places are affecting the amount of crime occurring. In such a way that with the expansion of cities, they form the focal points within their range, in which there are more crimes than other areas. The current research, which deals with the identification and analysis of shop stealing cases in the geographical area of ​​Semnan, has been used by Geographic Information System as well as SPSS software for spatial and temporal analysis as well as time. In this study, the crimes committed by the shop stealing from 1/1/1394 to 29/12/1394 were studied in the legal area of ​​Semnan as a statistical society. The method of research in this research is analytical and descriptive, and the data and information required for research is provided by two methods of library and field studies. The result of the study showed that the most important shops for stealing from Mazandaran crossroads to Imam Square, which are considered as a part of the commercial area of Semnan city, have been formed. In terms of time, June also has the highest incidence among other months. Distribution during the week and night hours, the early days of the week, as well as the early hours of the day, the highest rates, and the late hours of the week and the opening hours of the shops, have been the lowest reported in the theft.

The article is concluded with an outlook for some emerging trends.

The foundation of today''''s world is based on increasing productivity by using modern technologies and reducing costs. In road transport, the issue of promoting safety is one of the most important issues. Different approaches have been proposed to increase the safety of roads, each of which has advantages and disadvantages. The most effective options are the use of intelligent road transport systems to increase safety and reduce accidents. In this research, we have tried to compare the impact of the installation of intelligent systems and the correct location of the installation of these systems on road safety and reduction of road deaths by examining the objectives of ITS application and the impact of the installation of intelligent systems. This research, based on the descriptive-analytical method, has tried to evaluate the proper location of intelligent road transport equipment in the Shahrood-Sabzevar axis in Semnan province using the investigation and identification of strike sections. Using the analytical method, the status of existing systems Intelligent transportation has been evaluated according to technical criteria and criteria. Using the GIS location model, the location of installation of intelligent transportation systems in Shahrood has been taken. The analytical functions of multi-criteria model and need assessment of incident sections Identified by the province using ARC GIS software, GOOGLE EARTH, RMG and M AP SOURCE has been helped to select the optimal location for these systems. The results of the research show that in recent years, with the installation of intelligent road transport systems, the number of casualties in the outskirts of the province has decreased significantly. In total, the year 92, compared to the year 87, has a 37.6 percent reduction in casualties. This research, in addition to providing a template for the installation of intelligent systems in all parts of the province, can provide solutions for the optimal use of intelligent systems.

Crime is an unsuitable social phenomenon with many negative economic and social consequences. To control crime in the country, identifying the roots of crime is of great importance. The statistics show that there are important factors in the occurrence of the crime, one of the most important of which is environmental factors. Environmental factors are the basis for various types of crimes, one of the most important of which is theft of crime. The main purpose of this research is to investigate and identify the factors affecting theft in Kerman city in 2016, which has been investigated in four regions.
This research is an analytical-descriptive study and in collecting information, library methods, documents (use of documents, information and statistics of devices and organizations) and surveys have been used and mapping and analyzing information is also done using GIS software.
Findings: The main reasons for robbery in Kerman are unemployment, lack of policing control, spatial location, physical-environmental and time-based issue.
With the spatial analysis obtained in this study, it was found that the crime of robbery is more likely to occur on the outskirts of Kerman. Of course, in some of the central regions and the old texture, too much of this crime is due to environmental-physical conditions. Most cases of theft, including car theft, occurred in areas four, one, three, and two, respectively.

The field and purpose:

In this research, two critical issues of crisis management and road network in the strategic layer have been investigated by recognizing the criteria that have been emphasized in urban planning. Specifically, with the development of traffic-police designs and taking into account the requirements for coping with crises, it could be a good framework for establishing compatibility between traffic strategies and measures to reduce the effects of natural and man-made disasters. The purpose of this study is to simulate traffic nodes against possible earthquakes and to secure traffic on the road network in times of earthquake accidents.

This research is in terms of practical and in method of descriptiveanalytic. Data used were documentary, field and library and internet

were used for collecting and collecting information that the information on the research indicators was obtained through questionnaire with the advice of expert experts and municipality experts, crisis management and traffic police and evaluated and analyzed with the methods mentioned in the discussion.

At the analytical stage, at first the data of all indicators were descriptively analyzed through a questionnaire and extracted values based on Analytical Hierarchy Process (AHP) and Expert selection methods by weighting the relevant indexes. Then using the GIS software, the  vulnerability map of the area of Tehran region 21 FUZZY logic is presented.

The results of the study show that in the earthquake with the intensity of 7 mercilial, the most traffic nodes are in the range of very high, high, moderate, low and very low in area 3, region 2 and region 1 of the municipality respectively. In the end, the result was that in the event of an
earthquake with a 7-Mercantile earthquake in North Chitgar, Esteghlal, Villashahr and Werdavar have the highest traffic nodes in the very high range, which indicate a high degree of vulnerability to physical and traffic factors. The result is that the road network of Tehran 21 area in terms of crisis management requires a strategic plan and systematic solutions and is in the first priority of planning.

During recent decades gradually deteriorating neighborhoods and informal settlements, mainly on the periphery of major cities, outside the official program for urban development and gradually formed and expanded. Informal settlement in Iran, like many other countries, a phenomenon that is growing cities in the country is faced with new issues. Informal settlements, the causes of poverty and development, as well as endangering the environment and impose heavy costs to solve problems, is considered a serious threat to the stability and cohesion of the urban population, Mirror sphere of informal settlements as urban issues, the role and importance of scientific research has found. Aran Bidgol Yhyyabad neighborhood of the city as one of the settlements mentioned are faced with the phenomenon of informal settlements. In this study, anatomical pathology and insecurity in urban areas paid. The study area using GIS and Google Earth software, positioning and distribution, the percentage of social deviance and insecurity tends to be considered. Studies showed a tendency to social deviations (smoking, drug abuse, etc.) in more marginal areas is not excluded that all these factors together cause insecurity in urban space is Aran Bidgol.
