Environmental Quality Assessment of Tehran's Recent Urban Design Projects, Based on Place Check Technique in Experts and Public View Point

Urban space, as a place for social interaction, has a very important role in image of the cities and also in place competition between them. These issues along with the outstanding demands of citizens for the quality of urban spaces have led the urban authorities to reconsider such spaces, as Marvi Alley, Naser Khosrow, and Sabzeh Meidan, through definition and implementation of urban projects as well as organization of the public spaces. Some of these projects have been pursued with approaches of organizing and rehabilitation and some others through the approach of creation of places. The aim of this study is to assess the environmental quality of the new urban design experiences implemented in Tehran. This assessment will lead to achieve the most significant intellectual paradigm in these experiences. Case studies will include Naser Khosrow Street, Marvi Alley, Sabzeh Meidan, Bab Homayoun Street, Haft Howz Square, Bagh – e Ferdows, Chitgar Lake, Imam Hussein Square, Ab-o-Atash Park, Farahzad, Shohada Walk-Street and Saf Street. The research method is based on using place-check technique in field analysis, by urban design experts, at the first step. Then, survey research method was accomplished though collecting the questionnaires from 360 residents in the twelve case studies. The obtained Data were also analyzed by SPSS. v19 software. The results indicate that the pedestrian-oriented paradigms, as well as the environmental urban design, have been more influential in Marvi Alley, Naser Khosrow Street, Bab Homayoun Street, Imam Hussein Square, Sabzeh Meidan, Saf Street and Shohada Walk-Street, Abo- Atash Park, as well as Chitgarlake, generally more than other approaches.
