TRAFFIC FLOW THROUGH AN INTERSECTION BY REDUCING PLATOON INTERFERENCE
First Claim
1. In a computer product comprising a processor and memory, a method of improving traffic flow by analyzing traffic information corresponding to a cycle of a traffic signal, the method comprising:
- identifying a cluster in the traffic information;
determining that the cluster represents a group of vehicles that qualifies as an upstream platoon;
calculating properties of the platoon based on the traffic information; and
generating an Enhanced Platoon Coordination Diagram (EPCD) for the cycle based on the calculated properties of the platoon.

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.

25. A method of improving traffic flow, the method comprising:
-
detecting vehicles within a traffic stream along a continuous longitudinal section of a roadway; tracking the detected vehicles as the vehicles propagate towards a signalized intersection; identifying clusters of vehicles within the traffic stream based upon the tracking of the vehicles; determining which clusters belong to upstream platoons arriving at the intersection; calculating a velocity field for each of the upstream platoons; and determining properties of the upstream platoons based on the calculated velocity fields. - View Dependent Claims (26, 27, 28, 29)
