SYSTEM AND METHOD FOR MONITORING VEHICLES ON A ROADWAY
First Claim
1. A system for monitoring vehicles on a roadway, said system comprising:
- a plurality of RFID tags affixed at various pre-designated locations along a roadway, wherein each of said RFID tags is encoded with RFID tag information that may be used to determine a physical location of any of said RFID tags on said roadway;
a first RFID scanner installed on a first vehicle to wirelessly interrogate said RFID tags as said first vehicle travels on said roadway and/or to wirelessly receive said RFID tag information from said RFID tags as said first vehicle encounters any of said RFID tags on said roadway;
a first transceiver installed in said first vehicle and operatively connected to said first RFID scanner to receive said RFID tag information from said first RFID scanner and to re-encode and transmit at least said RFID tag information wirelessly as at least a first RF signal;
at least one roadside repeater station to wirelessly receive at least said first RF signal from said first transceiver and to re-transmit the information encoded in at least said first RF signal; and
a remote central tracking station to receive and process at least said re-transmitted information from said roadside repeater station in order to at least track a position of at least said first vehicle on said roadway.

Abstract
A system and method for tracking and monitoring vehicles on a roadway. RFID tags are positioned along the roadway and may be interrogated by vehicles equipped with an RFID scanner and a transceiver as the vehicles encounter the RFID tags along the roadway. The RFID tag information received by the RFID scanner is transmitted by the transceiver to a roadside repeater station which in turn sends the RFID tag information, as well as other identifying information, to a remote central tracking station. The remote central tracking station processes the RFID tag information and other information to determine a current position of a corresponding vehicle. Driver ranking profiles may be generated for drivers of vehicles and stored in a database in the central tracking station. The driver ranking profiles are used to restrict drivers in certain ways.

56. A method to generate a driver ranking profile for a roadway system, said method comprising:
-
assigning a first driver identification code to a first driver; assigning at least one type or class of vehicle that said first driver is authorized to drive on said roadway system; assigning hours of the day that said first driver is authorized to drive on said roadway system for each said vehicle type or class that said first driver is authorized to drive on said roadway system; assigning types of lanes that said first driver is authorized to drive in on said roadway system for each said vehicle type or class that said first driver is authorized to drive on said roadway system; assigning a speed limit that said first driver is obligated to adhere to while driving on said roadway system for each said vehicle type or class that said first driver is authorized to drive on said roadway system; storing said first driver identification code, said assigned type or class of vehicle for said first driver, said assigned hours for said first driver, said assigned types of lanes for said first driver, and said assigned speed limit for said first driver in a database; and associating said assigned type or class of vehicle for said first driver, said assigned hours for said first driver, said assigned types of lanes for said first driver, and said assigned speed limit for said first driver with said first driver identification code within said database to form a first driver ranking profile within said database. - View Dependent Claims (57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67)
