Determine the capacity for a two-lane approach to a signalized intersection that gets 45 seconds of green out of a cycle length of 100 secs. Studies show that the saturation discharge headway at the intersection is equal to 2.1 secs. Assume that the start-up lost time is equal to 2 secs, the clearance lost time is equal to 1.2 secs, and that the duration of the yellow interval is equal to 3.5 secs.
