<P>PROBLEM TO BE SOLVED: To provide a traffic line management system which detects change in a traffic line of a mobile object and discloses a cause of the traffic line change. <P>SOLUTION: An IC tag mounted on the mobile object, tag readers 30 to 39 for receiving information from the IC tag, a traffic line processor 100 for accumulating information received from the tag readers to process it, and cameras 20, 21 for photographing images are communicatively connected. The tag reader receives IC tag identification information (S501), and transmits, to the traffic line processor 100, the IC tag identification information and location identification information (S502). The traffic line processor 100, on the basis of the location identification information, obtains a traffic line, determines whether or not the traffic line is the same as previously stored movement (S504), extracts presence/absence of change in information of images photographed by the cameras 20, 21 if determined that the traffic line shows movement different from the previously stored movement (S506), and if the change is present, notifies a manager as such (S507). <P>COPYRIGHT: (C)2009,JPO&INPIT |
