Abstract

Systems and methods use cameras to provide autonomous navigation features. In one implementation, a system includes at least one image capture device configured to acquire at least one image of an area forward of the vehicle. The area includes a plurality of traffic lamp fixtures each including at least one traffic light. The system further includes at least one processing device configured to use at least one indicator of vehicle position, as determined from the at least one acquired image, to determine a relevance to the vehicle of each of the plurality of traffic lamp fixtures. The at least one processing device may determine, based on the at least one acquired image, a status of a traffic light included in at least one traffic lamp fixture determined to be relevant to the vehicle, and cause a system response based on the determined status.
