Analysis of the relationship between urban form and access indicator (Case study: Babolsar city)

city's form, is a container in which urban activities take place. The importance of the city's form is due to the functions that has for resident; including Its important functions are the amount of access. The purpose of this study, is measure the relationship between the form and the level of access at the neighborhood level of Babolsar. Research in terms of nature is descriptive-analytical and according to the purpose is practical. Data and information are extracted from the statistical blocks of the Statistics Center and land use maps of the municipality SPSS and GIS have been used to classify them. To measure the form three density, congestion and mixing indicators and 10 related variables were used and Hansen's attraction model was used to calculate the access indicator. The results of Pearson correlation test showed a direct and significant relationship between the form and access (r = 0.668) and compaction has a direct impact on the increase in access rates. This issue is most visible in the central regions of the city; so that the more densely populated areas are, the amount of access increases dramatically. Based on the results, the three main indicators of form have a direct and significant effect on the access indicator, due to their differences in different locations, the result was an imbalance in the spatial structure of Babolsar. Another interesting finding of this study is the high proportion of ownership of automobiles in densely populated areas of Babolsar over peripheral regions, this can be contradicted by the principle of the pedestrian, which is one of the important principles of achieving the city's sustainable form.
