The time values of the saturation flow rate in signalized intersections play a key role in their schedule, and performance. So far, studies have been done to estimate average discharge headway of the nearside legs of intersection. While its values are not the same as far-side legs due to the number of lines, driver behavior and other physical characteristics. In the present paper, with the help of field data acquisition at five signalized intersections in Rasht city. Then estimated and compared the values of the time of discharge and delay time in the nearside and far-side legs of the signalized intersection. The results show that saturation conditions occur between the second and last vehicle in the far-side legs and between the fifth or sixth vehicle in nearside legs intersection. In other words, the number of vehicles with start-up delay is 1 or 2 vehicles and 4 or 5 vehicle in the far-side and nearside legs respectively. Also, the amount of saturation headway of far-side legs is less than the nearside legs.
