Abstract:
Embodiments describe new mechanisms for signalized intersection control. Embodiments expand inputs beyond traditional traffic control methods to include awareness of agency policies for signalized control, industry standardized calculations for traffic control parameters, geometric awareness of the roadway and/or intersection, and/or input of vehicle trajectory data relative to this intersection geometry. In certain embodiments, these new inputs facilitate a real-time, future-state trajectory modeling of the phase timing and sequencing options for signalized intersection control. Phase selection and timing can be improved or otherwise optimized based upon modeling the signal's future state impact on arriving vehicle trajectories. This improvement or optimization can be performed to reduce or minimize the cost basis of a user definable objective function.

Claim (Index 9):
A self-configuring traffic signal controller apparatus, the apparatus comprising:\n a traffic controller comprising electronic hardware that:\n receives sensor data from a trajectory sensor at an intersection, the trajectory sensor optionally including a radar or video camera; \n generates trajectory data from the sensor data based on intersection geometric data about the intersection stored in data storage, the trajectory data comprising data about vehicles speeds; \n automatically adjusts a signal timing configuration of the traffic controller by analyzing the trajectory data according to user-defined policies; and \n outputs control signals to traffic signal lights according to the adjusted signal timing configuration to cause the traffic signal lights to selectively turn on and off the traffic signals according to the adjusted signal timing configuration.
