A signalized intersection approach has three lanes with no exclusive left- or right-turning lanes. The approach has a 50-second green out of a 110-s cycle. The yellow plus all-red intervals for the phase total 5.2 s. If the start-up lost time is 2.2 s/phase, the clearance lost time is 1.2 s/phase, and the saturation headway is 2.35 s/veh under prevailing conditions, what is the capacity of the intersection approach?
