Abstract
Methods, systems, and computer program products for optimizing automobile traffic flow through an intersection by detecting and reducing platoon interference. One method, performed in a computer product, includes steps of identifying a cluster in traffic information of a cycle of a traffic signal, determining that the cluster qualifies as an upstream platoon, calculating properties of the platoon, and generating an Enhanced Purdue Coordination Diagram (EPCD) for the cycle based on the calculated properties of the platoon. Another method includes obtaining, by a computer device, traffic information corresponding to an intersection; determining, by the computer device, platoon properties of the traffic information corresponding to each cycle of a traffic signal; and calculating, by the computer device, a timing change to make to the traffic signal to improve traffic flow through the intersection, the timing change being based on the platoon properties.
