Spatial Analysis of the Relationship of Urban Form with Access Index (Case Study: Maragheh City)

Urban form is based on environmental conditions and planning decisions in the context of time.The study of urban forms,is important due to its effects on urban functions,including the quality of citizens access to services located in the city.Each of the urban forms is compact or scatter are impact in the access of citizens to services.The purpose of this research is to identify the urban form of urban neighborhoods in Maragheh and how citizens access to urban services.Research in terms of the nature of the descriptive analytical type that has been done through the documentary library study.in data analysis from Fuzzy method and GIS and SPSS software were used.The research findings show that the Maragheh urban form pattern has been developed intensively and scattered. That way,the city in the center and the old textures have compact and dense patterns and in the periphery and marginal tissues are scattered and semi-dispersed.On the other hand, the results of the correlation analysis between the dense form and the access index indicate is a significant correlation between these two variables.So that the access to neighborhoods and central areas is better than the marginal and the new ones.On the other hand,some accessibility indicators such as the ratio of communication network in central neighborhoods have a lower share than marginal neighborhoods. This factor,along with the establishment of many activities and facilities in this part of the city, has led a large amount of intra-city trips to the city's central neighborhoods,resulting in heavy congestion and traffic problems.
