Logic says that it should work, unfortunately drivers have the car in gear and brains in neutral. =20 Gut feeling is that it will be trouble, so suggest make it main road revert and maintain VA, preferably MOVA if isolated, with as a short cycle as possible; under 60 sec's, even 40 if only two stage. As background, using demand dependant side roads on UTC helps with claims of overnight delay no end.
