Timeline of Operations 1) InSync chooses & Initiates Sequence that “Best” meets Real-time Demand Early release Traffic does not create a Global adjustment, thus downstream intersections may optimize their secondary movements accordingly. Intelligently serves an Early Release state due to lack of demand that matches proper coordinated sequence. 62 sec 2) Time is Given to then intelligently services all movements as secondary movements One Period = 125 sec InSync jumps back and forth across the “Barrier” freely without referencing a “Ring” while following SAFE sequences deter- mined by the User.
