Abstract:
A traffic signal fixture verification system including an optical recognition means configured to obtain one or more images of two or more traffic signal fixtures in proximity to an ego vehicle, and to detect a motion status of one or more vehicles in proximity to the ego vehicle, a processing means configured to determine a relevance value for two or more traffic signal fixtures identified in the one or more images, monitor a status of each of two or more relevant traffic signal fixtures having a relevance value greater than a threshold value, and based on the relevance values of the two or more relevant traffic signal fixtures, the respective status of each of the two or more relevant traffic signal fixtures, and optionally, and/or the motion status of the one or more vehicles surrounding the vehicle, actuate an accelerator function or a braking function of the ego vehicle.
