1. A method for interpreting traffic information by a vehicle, comprising:
collecting, by a processor, sensor data from at least one first sensor device of the vehicle;
determining, by the processor, at least one relevant object within the sensor data based on a window defined by a plurality of ranges and associated elevations, wherein the plurality of ranges and associated elevations are defined relative to the at least one first sensor device;
determining, by the processor, a confidence score of the at least one relevant object based on an identification of at least one pattern of activity of other objects associated with an intersection;
determining, by the processor, a subset of sensor data from at least one second sensor of the vehicle based on the confidence score of the relevant object;
generating, by the processor, traffic device data for use in controlling the vehicle based on an evaluation of the subset of sensor data, wherein the window is updated based on a confirmation of the traffic device data and;
implementing, by the processor, an autonomous driving system (ADS) comprising a vehicle control system, wherein the vehicle control system navigates the vehicle based on the traffic device data.
