applying the land use-transportation integrated model, using the most effective sustainable urban variables case study: part of the district 22 of city of tehran

land use planning is the main core of urban planning and one of the main components of an urban system. this element has close relation with transportation system of the city, so if their interaction becomes insufficient, deterioration and chaos would have an adverse impact on the urban system and would cause serious environmental issues. the integrated land use-transportation models seem to be the ones that can help to create efficient interaction between land use and transportation systems. since the introduction of sustainability to urban studies, urban researchers have tried to investigate and use the variables that will help to achieve urban sustainability in the models. this analytical-documental research (with a quantitative approach), with emphasis on sustainability tries to verify the most effective variables in the above  mentioned models, and then propose a process with a particular kind of analysis. the verified variables and the process are then examined in part of the 22nd district of tehran as the case study. our findings indicate that; applying the chosen variables in the model and simulation process will make significant reduction in energy use, pollution (mo2), and delay (direct effects on environment and economy). the indirect effect shows itself on social aspect since the mentioned changes are related to the citizens conveniences.
