"\"<Definition> The type of overlap operation for this row. The types are as follows: other: The overlap operates in another mode than those described herein. normal: The overlap output shall be controlled by the overlapIncludedPhases when this type is indicated. The overlap output shall be green in the following situations: (1) when an overlap included phase is green. (2) when an overlap included phase is yellow (or red clearance) and an overlap included phase is next. The overlap output shall be yellow when an included phase is yellow and an overlap included phase is not next. The overlap output shall be red whenever the overlap green and yellow are not ON. minusGreenYellow: The overlap output shall be controlled by the overlapIncludedPhases and the overlapModifierPhases if this type is indicated. The overlap output shall be green in the following situations: (1) when an overlap included phase is green and an overlap modifier phase is NOT green. (2) when an overlap included phase is yellow (or red clearance) and an overlap included phase is next and an overlap modifier phase is NOT green. The overlap output shall be yellow when an overlap included phase is yellow and an overlap modifier phase is NOT yellow and an overlap included phase is not next.

(2) when an overlap modifier phase is red and an overlap included phase is yellow. The overlap output shall be red when an overlap modifier phase and an overlap included phase are red. The overlap output shall be flashing red when an overlap included phase is green and an overlap modifier phase is red. transit-2: The overlap output shall be controlled by the overlapIncludedPhases when this type is indicated. The overlap output drives a 2-section bar signal for transit vehicles using overlap green (vertical bar) and red (horizontal bar) outputs. The overlap output shall be green in the following situations: (1) when an overlap included phase is green. The overlap output shall be flashing green when an overlap included phase is yellow and an overlap included phase is not next. The overlap output shall be red whenever an overlap included phase is red. minusGreenYellowAlternate: The overlap output shall be controlled by the overlapIncludedPhases and the overlapModifierPhases if this type is indicated. The overlap output shall be green in the following situations: (1) when an overlap included phase is green and an overlap modifier phase is NOT green. (2) when an overlap included phase is yellow (or red clearance) and an overlap included phase is next and an overlap modifier phase is NOT green and an overlap modifier phase is not next. The overlap output shall be yellow when an overlap included phase is yellow and an overlap modifier phase is NOT yellow and an overlap included phase is not next. The overlap output shall be red whenever the overlap green and yellow are not ON.
