Abstract

The form of the city is very important because it forms the basis of urban movements within itself. One of the key components of treating the quality of the urban form is access to urban activities and services. The expansion of the horizontal growth of the metropolis of Tehran in the last few decades has caused the fabric and structure of this city to move towards instability, which results in unequal and unbalanced access to different parts of the city. Therefore, the structuring of the city in such a way as to meet the needs of the citizens in the shortest distance from the residential area and easily, is very important in urban planning. The present research was conducted with the aim of investigating the condition of the form and accessibility of the neighborhoods of Tehran. The necessary data and information were extracted from the statistical blocks of the Statistics Center, the land use map of the city, and the Open Street Map website, and GIS and Excel software were used to analyze the data. 3 main indicators of density, connection and mixing were used to evaluate the urban form, and Hansen's gravity model was used to measure accessibility. The results of the research showed that the neighborhoods in the central part of Tehran have a more stable form compared to other neighborhoods, and the western neighborhoods of Tehran have an unstable form. The access factor in Tehran also showed that the central and northern parts of the city are in a better condition than other parts of the city in terms of access. The results obtained from the correlation test also showed that there is a direct and significant relationship between urban form and accessibility; But the degree of correlation between them is not strong. Meanwhile, among the urban form indices, the building density index has the highest correlation with urban accessibility.
