Abstract
By narrow region communication between a gate side communication apparatus (G-COM) and a mobile unit side communication apparatus (M-COM) passing through an on-road real gate at an interconnection, the G-COM assigns a real identification code (R-ID) IDincluding an intersection number to the M-COM after receiving a R-ID IDhaving been assigned from the M-COM, while time series pictures of the intersection including all real gates are taken by a camerainstalled to assign a virtual identification code (V-ID) to a mobile unit passing through a slit, corresponding to a real gate, in pictures by processing them. In response to the assignment of the R-ID, the R-ID is brought into correspondence with the V-ID. The mobile unit is tracked and when an anomalous behavior thereof is detected in pictures, warning information is transmitted to the M-COM using the corresponding R-ID. By gathering sets of IDand IDassociated with each other in a plurality of intersections, a mobile unit having displayed an anomalous behavior is tracked.
