1. A method of generating an output movement layout for a traffic 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; and
generating an output movement layout for the intersection based on the generated angular cluster chart.
