Patent ID: 8050854

Claim:
A method for controlling traffic movements for a plurality of traffic intersections each having a volume of traffic comprising: determining a critical intersection having a most conflicting volume from among the volumes; determining a plan at an adaptive control system with at least one guaranteed green time and at least one minimum green duration for at least one direction of traffic movement at the critical intersection and a period for the plan; determining other plans with other guaranteed green times and other minimum green durations for other intersections based on the at least one guaranteed green time and the at least one minimum green duration at the critical intersection and an expected travel time between the critical intersection and the other intersections, each other plan having another period; determining at least one non-linear schedule for the critical intersection at the adaptive control system based on the at least one guaranteed green time, the at least one minimum green duration, the period, and queue lengths for individual phases at the critical intersection; determining other non-linear schedules for the other intersections based on the other guaranteed green times, the other minimum green durations, the other periods, and other queue lengths for other individual phases at the other intersections; controlling at least one traffic signal at the critical intersection according to the at least one non-linear schedule; and controlling other traffic signals at the other intersections according to the other non-linear schedules.
