METHOD AND APPARATUS FOR TRAFFIC CONTROL USING RADIO FREQUENCY IDENTIFICATION TAGS
First Claim
1. A computer implemented method for controlling traffic flow, the computer implemented method comprising:
- monitoring a set of radio frequency identification tags located in a set of vehicles moving from one radio frequency identification tag sensor to another radio frequency identification tag sensor in a network of radio frequency identification tag sensors relative to a traffic light to obtain location data for the set of vehicles;
identifying times needed for the set of vehicles to travel from the one radio frequency identification tag sensor to the another radio frequency identification tag sensor to form time data;
identifying a traffic pattern relative to the traffic light from the time data;
determining whether the traffic pattern is a delayed traffic pattern for the traffic light; and
responsive to a determination that the traffic pattern is a delayed traffic pattern for the traffic light, changing timing of the traffic light to increase the traffic flow through the intersection.

Abstract
A computer implemented method, apparatus, and computer usable program code for controlling traffic. A set of vehicles is monitored moving from one radio frequency identification tag sensor to another radio frequency identification tag sensor in a network of radio frequency identification tag sensors to detect movement of the set of vehicles. A set of traffic patterns is identified in response to detecting the movement of the set of vehicles. A determination is made as to whether a traffic pattern in the set of traffic patterns is a delayed traffic pattern. In response to a determination that the traffic pattern in the set of traffic patterns is the delayed traffic pattern for a traffic control light at an intersection, the timing of the traffic control light is changed to increase traffic flow through the intersection.
