摘要： An external adaptive control system and method control a traffic signal controller assembly. The external adaptive control system determines a non-linear schedule with one or more states corresponding to one or more individual phases with each state having a start time and a duration. The external adaptive control system generates presence data for reception by the controller assembly for each state and its associated duration.

摘要： An adaptive control system controls a traffic signal at a critical intersection that has a most conflicting volume of traffic among volumes of traffic at intersections in a traffic network. The adaptive control system determines a plan identifying a guaranteed green light time and a minimum green duration and a period for the plan. The adaptive control system determines, based on the plan, a non-linear schedule with one or more states corresponding to one or more individual phases with each state having a state start time and a state duration. Queues for individual traffic movements at the critical intersection also may be used to determine the non-linear schedule. The adaptive control system controls the traffic signal according to the non-linear schedule. The adaptive control system transmits its plan to one or more other adaptive control systems for other intersections. The other adaptive control systems determine other plans based on the plan from the adaptive control system and an expected travel time between the critical intersection and the corresponding intersection.
