Vehicle controller circuitry for a subject vehicle. The vehicle controller circuitry includes vehicle constraint determination circuitry to determine vehicle constraints including predicted values for vehicle speed of at least one other vehicle and predicted values of for vehicle position of the at least one other vehicle relative to the subject vehicle, wherein the vehicle constraints are determined at predetermined time steps (k) over a time horizon (Th). The vehicle controller circuitry also includes traffic signal constraint determination circuitry to determine, within a distance horizon (Dh) from the subject vehicle, traffic signal constraints including a green signal state of at least one traffic signal, a distance to the at least one traffic signal relative to the subject vehicle, and a time remaining in the green signal state of the at least one traffic signal; wherein the traffic signal constraints are determined at the predetermined time steps (k) over the time horizon (Th). The vehicle controller circuitry also includes acceleration profile (AP) determination circuitry to determine at least one AP for the subject vehicle based on the vehicle constraints, the traffic signal constraints and a minimum safe distance from the at least one other vehicle; wherein the at least one AP comprising k number of acceleration values, which when applied to the subject vehicle at each time step k will cause the subject vehicle to travel at a target velocity that is sufficient to pass through the at least one traffic signal while in the green signal state and while maintaining at least the minimum safe distance to the at least one other vehicle.
