Abstract: 

Corsim is microscopic simulation software in traffic engineering with high capability in analyzing urban networks. Nowadays, the use of simulation software is a fundamental way to solve traffic problems. Applying simulation software is very economic, yet the results are obtained in very short time without any traffic disturbances, whereas using field tests, in addition to being expensive, disturbs traffic flow. In this research, capacity analysis and flow optimization of Dastghaib Street, between Ostad Moin Boulevard and Ayatollah Saidi highway, is analyzed by Corsim in Tehran. Input data was taken by municipal GIS files and field investigations. Simulation of the network was proposed in morning and afternoon peak hours. The results showed that when Dastghaib Street was made one-way, total network delays were decreased 7.3 percent and 4.9 percent in the morning and afternoon peak hours, respectively. Also, total travel time decreased from 124 hours to 120 hour, while average speed increased from 20 km/h to 22 km/h in morning peak hours.
