Feasibility Study of Dynamic Lane Management in Urban Roads

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. Therefore, in the network of urban thoroughfares, one can find highways that are crowded in one direction in the morning and in the other direction in the evening. By allocating a lane from a not crowded to a crowded time at different times of the day, arrangements can be made to reduce the volume and congestion of highways. In this research, by implementing a part of Hemmat highway in Aimsun simulation software, it has been investigated to what extent this method improves the traffic situation. Input information to the software such as traffic volumes, vehicle dimensions, vehicle speed, number of lanes and lane width were obtained from the field study and output parameters including delay, speed, travel time, distance traveled and fuel consumption from the software output. To do this, the current state of the study area and the proposed scenario, ie assigning a band from not crowded to crowded, were implemented in the simulator software, and the results of their simulation were compared. Based on this, at the peak of the morning, the route changed to 5 lanes from 4 lanes and the return route changed from 4 lanes to 3 lanes and vice versa.
