Demand for travel in Tehran, in line with the movement of people to work, increases in the morning from different areas to the city center and in the evening from the center to other areas. , an area including Shahid Hemmat Highway has been examined. Based on the simulation in Aimsun software, according to traffic input information such as vehicle volumes, vehicle dimensions, vehicle speed, physical parameters including delay, speed, travel time, mileage and fuel consumption index has been extracted. First, traffic volumes were counted at different times of the day and traffic information, including peak hours, was obtained from traffic volume information. In the next step, the speed of the vehicles,, after drawing the researched network in the software environment, the collected information including the equivalent rides, speed and capacity has been entered into the Aimsun software. Then, the current situation of the study area is compared with the proposed scenario, ie allocating a lane from solitude to crowded direction. Based on the simulation results, it was found that at the peak of the morning, the conversion path to 5 lines from 4 lines and the return path conversion from 4 lines to 3 lines improve performance indicators including latency, speed, travel time, density.At the peak of the evening, if the route is changed from 4 lines to 3 lines and the return path from 4 lines to 5 lines, it will improve performance indicators
