Abstract: Traffic signal control systems and methods in accordance with various embodiments of the invention are disclosed. One embodiment includes: at least one image sensor mounted with a bird's eye view of an intersection; memory containing a traffic optimization application and classifier parameters for a plurality of classifiers, where each classifier is configured to detect a different class of object; a processing system. In addition, the traffic optimization application directs the processing system to: capture image data using the at least one image sensor; search for pedestrians and vehicles visible within the captured image data by performing a plurality of classification processes based upon the classifier parameters for each of the plurality of classifiers; determine modifications to the traffic signal phasing based upon detection of at least one of a pedestrian or a vehicle; and send traffic signal phasing instructions to a traffic controller directing modification to the traffic signal phasing.
