This document describes methods to assign a collective state to a group of traffic signal devices (105, 110, 125) that are detected by multiple cameras (145). The states may be color states or other states. The system will process images (200) to identify states of each device (105, 110, 125) in the images (200). When the devices (105, 110, 125) exhibit more than one state, the system will determine an overall state for the group by generating a confidence score for each state and selecting the state having a confidence score that exceeds a threshold. The system will then use the selected state to assign an overall state to the group of traffic signal devices (105, 110, 125). The system may use the overall state to generate a signal causing the vehicle (130) to perform an action such as a motion control action, or output an audible or visual alert.
