SMART TOLL NETWORK FOR IMPROVING PERFORMANCE OF VEHICLE IDENTIFICATION SYSTEMS
First Claim
1. A method for vehicle identification and toll computation for a vehicle having travelled on a toll road, comprising:
- performing absolute vehicle identifications of vehicles entering said toll road utilizing an automated license plate recognition system;
performing absolute vehicle identifications of vehicles exiting said toll road utilizing said automated license plate recognition system;
pairing successful said absolute vehicle identifications of said vehicles entering said toll road and successful said absolute vehicle identifications of said vehicles exiting said toll road;
creating a set of unpaired vehicles wherein said unpaired vehicles are one of the following;
1) a successful absolute identification vehicle at an entrance of said toll road without a corresponding successful absolute identification at an exit of said toll road,
2) a successful absolute identification vehicle at said exit of said toll road without a corresponding successful absolute identification at said entrance of said toll road or
3) an unsuccessful absolute identification vehicle at either said entrance or said exit of said toll road;
matching said unpaired vehicles using signature matching to pair said successful absolute identification vehicles with said unsuccessful absolute identification vehicles wherein said signature matching identifies said unpaired vehicles utilizing non-optical character recognition of said unpaired vehicles; and
assigning absolute vehicle identifications to said unsuccessful absolute identification vehicles if matched with one of said successful absolute identification vehicles and computing tolls on a basis of said parings.

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.
