A comparative study of the effectiveness of the production of riding and walking space on the quality of the urban environment(Case: 22 Districts of Tehran city)

Tehran metropolis has faced many environmental pollutions in recent decades and its quality has been affected.This situation has been paralleled by the ever-increasing population and, as a result, the significant increase in the reliance on motor vehicles for intra and extra-urban trips in this metropolis.  The purpose of this study is to evaluate the environmental quality of Tehran and its spatial relevance to transportation variables. This research has been done by quantative method and using the data of the statistical yearbook of Tehran province in 2019. Shannon entropy weighting method and Promethee multi-criteria decision making technique for evaluating and ranking Tehran regions in terms of environmental quality, hierarchical clustering in SPSS environment for clustering 22 regions and bivariate Moran autocorrelation analysis in Geoda software to study spatial coherence And environmental quality quotes are used. The results indicate the existence of major spatial differences between different regions of Tehran in terms of environmental quality and regions are divided into four major clusters. Positive and negative relationships between transport variables and environmental quality were observed in the form of different spatial patterns in the regions and spatial clusters and non-clusters were analyzed. The results showed that the production of riding space and the increase in travel production, under the influence of artificial road construction in the second cycle of capital accumulation and Fordism mass production style, has a negative spatial correlation with the quality of the urban environment.
