Abstract

A smart toll network system for “network-based” analysis via communication of relevant vehicle identifications among to stations (i.e., by forming a smart toll network) coupled with a probabilistic-based search is disclosed. Comparing vehicle identification data (such as license plate recognition and vehicle signatures) between toll stations improves the performance relative to point-based vehicle identification analysis. Of the vehicles unidentified by license plate recognition, vehicle signatures are used to link each of them to the corresponding vehicle at the opposite end of the tolling system. If license plate recognition fails on a vehicle at an exit station, vehicle signatures can be used to find the location where that vehicle entered the tolling system. If license plate recognition was successful at the entrance station, that same license plate number can be assigned to that vehicle at the exit station, on the basis of the vehicle signature matching, without requiring human intervention.
