Quantitative modeling of access to urban parks with spatial justice approach, urban parks in Zone 6 in Tehran

The spatial equity of urban public facility is an important goal to urban planners. Therefore, spatial justice measuring in terms of access to public spaces, such as green spaces and urban parks, is a need of urban management. In this study, for assessment of spatial equity by using Geographic’s information systems (GIS) technology and network analysis have been presented a quantitative method for measuring the accessibility to urban parks in the zone 6 in Tehran municipality. Gravity or weight of each park, the network distance of urban blocks and radius of access is the main criteria of this research. The results showed, with regard to network distance, instead of direct distance, spatial distribution and development of parks in zone 6 have been unjust and there is poor access to the parks. The proposed analysis method has the ability of a Quantitative comparison between urban blocks in terms of their accessability to urban parks and their ability to identify the blocks with the least access.
