C onclusions The assessment of the intersection was performed by important parameters such as considering delay, queue, fuel consumption, amount of pollutantsand level of service. The analysis showed the existing condition at the intersection was stable flow with average delay of 21.61second/vehicleand LOS -C.Two alternatives to improve the intersection performance were investigated using Vissim 20: Alternative 1 and Alterative 2. The first alternative was re-designing green time of traffic light and the second alternative were consisted of re-designing green time and changed type of intersection. The 1 st alternative obtained LOS of F in 2030 year, average delay of 89 second/vehicle, queue 231.5 meters. The 2 nd alternative resulted performance was increasing with average delay of 81.1 second/vehicle, maximum vehicle queue 257.42meters and LOS of F in 2027 year. Alternative 1 is considered the best solution, this option will reduce delay by 25 %, queue by 21 %, decrease the congestion cost by 25 %, and increase LOS. In general, the 1st alternative improves the intersection performance significantly for long period of time. Based on the computer modeling results in all three conditions, the second scenario is the best option with optimization of traffic signals with the PTV vissim simulation software.
