Claim 6:
7. A method for verifying a status of a traffic signal fixture from an ego vehicle, comprising:
obtaining one or more images of two or more traffic signal fixtures in proximity to the ego vehicle;
detecting a motion status of one or more vehicles in proximity to the ego vehicle;
determining relevance values for a plurality of traffic signal fixtures identified in the one or more images;
grouping each of the plurality of traffic signal fixtures that have a same reference value into respective signal groups;
determining which one of the signal groups has relevance values greater than a threshold value;
monitoring a status of each of the traffic signal fixtures in the signal group, from among the 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, actuating 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, actuating 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.
