3. An intersection approach has two lane groups: left-turn lane group, and through/right-turn lane group. The control delay is 37 seconds/vehicle for the left-turn lane group, and 27 seconds/vehicle for the through/right-turn lane group. The analysis flow rate is 97 vehicles/hour for the left-turn lane group, and 450 vehicles/hour for the through/right-turn lane group. Calculate the approach control delay and write the corresponding level of service (LOS) for the approach in the box below.
