Introduction and purpose: Urbanization growth and the emergence of the metropolitan phenomenon caused several problems which include the transportation system and traffic. One solution to the above-mentioned problems proposed by urban researchers has been the construction of underpasses in cities. In the past few years, in Valiasr intersection areas in Tehran, similar problems of traffic congestion have been prevalent, making transportation and travelling difficult. Indeed, the construction of Valiasr underpasses wiped out some of the problems. The present study aimed to assess the effectiveness of this underpass and its relationship to sustainability.
Method: The research adopted descriptive-analytical methodology with the aim of being practical and developmental. Data were collected in two ways: library research and field studies. Field data were based on a sample size of 200 questionnaires. The garnered data were entered into SPSS software. For the analysis, in addition to descriptive statistics, Pearson test and ANOVA were used
Findings: The obtained results showed that the performance was above average and the underpass in intersection of Valiasr with 7 indicators of traffic. Furthermore, the relationship between performance and sustainability was shown to be meaningful and significant (P>. 05). This also shows the regression relationship between indicators of performance and sustainability in one way ANOVA table
Conclusion: Valiasr Intersection underpass can be considered as a successful urban project though there are some defects, the most important of which is why fellow citizens pass underground while automobiles move over the ground. However, this project was an inevitable response to existing problems and has been successful so far. Finally, in order to increase the efficiency of the underpass, some suggestions such as constructing elevators for the disabled or special individuals have been made
