Method of identifying vehicle turning movements at intersections from trajectory data and reallocating green time therefor

A method of automatically reallocating green time between different movements for a traffic light in a traffic intersection, comprising:

• receiving traffic intersection geographical data;
• establishing a center point for the traffic intersection;
• receiving connected vehicle (CV) data from vehicles approaching and within the traffic intersection based on a predetermined distance from the center point;
• establishing an area of interest for the traffic intersection based on the received CV data;
• establishing entry and exit headings for each vehicle based on the CV data;
• generating direction groups based on the entry and exit headings of each vehicle;
• generating an output movement layout for the traffic intersection based on the generated directional groups;
• identifying overcapacity or under-capacity state for each generated output movement thereby determining delay and number of stops for each vehicle in the traffic intersection;
• and
• reallocating green time between movements on a traffic light at the traffic intersection to reduce congestion and minimize vehicles during one cycle of the traffic intersection traffic lights based on any under-capacity movement at the traffic intersection.
