Claim 14:
15. A method of automatically reallocating green time between different movements for a traffic light in an intersection, comprising:
receiving intersection geographical data;
establishing a center point for the intersection;
receiving vehicle global positioning system (GPS) data;
establishing a radius of interest for the intersection based on the received vehicle GPS data;
establishing entry and exit headings for each vehicle based on the GPS data;
generating an angular cluster chart based on the entry and exit headings of each vehicle;
generating an output movement layout for the intersection based on the generated angular cluster chart;
identifying overcapacity or under-capacity state for each generated output movement thereby determining delay and number of stops for each vehicle in the intersection; and
reallocating green time between movements on a traffic light at the intersection to clear all vehicles during one cycle of the intersection traffic lights based on any under-capacity movement at the intersection.
