20090051568 | METHOD AND APPARATUS FOR TRAFFIC CONTROL USING RADIO FREQUENCY IDENTIFICATION TAGS - 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.
