Actuated coordinated operation is defined as actuating a specified period of the coordinated phases, as opposed to non-actuated coordinated operation, in which the coordinated phases are set to recall. In this study, we investigate the operational impacts of actuating the coordinated phases (10% of cycle) at an actuated intersection using measures of effectiveness calculated on a cycle-by-cycle basis. Based upon three weeks of before data and three weeks of after data, we conclude that the use of actuated coordinated phases instead of non-actuated coordinated phases can better balance volume-to-capacity ratios and decrease split failures for the minor street movements without major costs to progression through the coordinated movements. The paper recommend agencies actuate the coordinated phase to provide robust control that more effectively respond to changing traffic conditions.
