Claim 0:
1. A traffic signal fixture verification system for an ego vehicle, comprising:
optical recognition means configured to obtain one or more images of two or more traffic signal fixtures in proximity to the ego vehicle, and to detect a motion status of one or more vehicles in proximity to the ego vehicle;
processing means configured to:
determine relevance values for a plurality of traffic signal fixtures identified in the one or more images;
group each of the plurality of traffic signal fixtures that have a same reference value into respective signal groups;
determine which one of the signal groups has relevance values greater than a threshold value;
monitor a status of each of the traffic signal fixtures in the signal group, from among the respective signal groups, that has the relevance values greater than the threshold value;
perform a comparison among all of the traffic signal fixtures in the signal group that has been monitored to determine whether the status of all of the traffic signal fixtures are identical; and
upon the determination that the status of all of the traffic signal fixtures in the monitored signal group are identical, actuate an accelerator function or a braking function of the ego vehicle based on the status of all the traffic signals fixtures in the signal group, and
upon the determination that the status of all of the traffic signal fixtures in the monitored signal group are not identical, actuate an accelerator function or a braking function of the ego vehicle based on at least one of (i) the status of the traffic signal fixture in the signal group that has a highest safety factor or (ii) the motion status of the one or more vehicles surrounding the ego vehicle.
