RADIO FREQUENCY IDENTIFICATION NUMBERING FOR CORRECT DIRECTION INDICATION

摘要

A computer implemented method, apparatus, and computer usable program code for determining a proper direction of travel of a vehicle. A first value is received from a first radio frequency identification tag by the vehicle. A second value is received from a second radio frequency identification tag by the vehicle. A first value and a second value associated with the radio frequency identification tags are identified. A determination is made whether the second value is in an ordinal sequence with the first value to denote the proper direction of travel. In response to a determination that the second value is not in sequence with the first value, a signal is sent that the direction of travel of the vehicle is contrary to the proper direction of travel.
