Claim 10:
11. A system comprising:
a processor; and
a memory containing programming instructions that are configured to cause the processor to determine an overall state of a group of traffic signal devices by:
receiving a plurality of images that were captured by a plurality of sensors coupled to a vehicle, wherein the images each depict a group of traffic signal devices,
in response to the traffic signal devices of the group exhibiting a plurality of states in the one or more images, the plurality of states including a red state and non-red state:
generating a confidence score for each of the states; and
selecting, from the plurality of states, a state having a confidence score that exceeds a threshold, wherein the red state is associated with a first threshold, and the non-red state is associated with a second threshold higher than the first threshold,
using the selected state to assign an overall state to the group of traffic signal devices, and
using the overall state to generate a signal that will cause the vehicle to perform an action.
