A system for tracking vehicle position using a smart phone in the vehicle as an active transponder, which is detected by roadside equipment is disclosed. In an embodiment, the system uses existing RF transceivers on the smart-phone, such as Bluetooth LE or WiFi to periodically transmit an identifying message. Road-based equipment detects and locates the smart phone. In a further embodiment, the smart phone is alerted by roadside beacons and only then responds with its identification information. Processing can be performed either on the smart phone or by roadside or central office equipment as is the case in prior art active or passive transponder-based tolling systems. Vehicle location detection can be enhanced through the use of directional antenna matrices such as a Butler matrix. The system can be used for automated roadway tolling and monitoring.

Vehicle tracking system using smart-phone as active transponder

An RFID transponder including a Bluetooth® compatible transceiver (BLEET) is described. The Bluetooth® compatible transceiver may be configured to set data that is transmitted via one or more RFID transceivers in the transponder and to return data received by the RFID transceiver(s) to a client application running, for example, on a user's smart phone. The BLEET may be used for electronic vehicle tracking or tolling. Vehicle occupancy data may be set by the user with the client application via a Bluetooth® connection in connection with high occupancy vehicle tolling and express lane incentive programs. The BLEET may be used in a congestion pricing (CP) toll area, wherein the smart phone determines a toll rate based on the location, when triggered by the BLEET, that the BLEET was read by an RFID reader located on a boundary of the CP toll area.

Vehicle tracking system for congestion pricing using transponders

A system is described for tracking vehicle position using a smart phone or similar device as an active transponder that communicates with roadside equipment. The system may uses existing RF transceivers on the smart-phone, such as Bluetooth® LE or WiFi to periodically transmit an identifying message. Road-based equipment detects and locates the smart phone. In a further aspect, the smart phone is alerted by roadside beacons and responds with identification information. Transaction processing may be performed either on the smart phone or by roadside or back office equipment. The system may be used for automated roadway tolling and monitoring and also for access control. A coded card may be scanned by the smart card to enter identification for access control.

Vehicle tracking system using transponders

A system combining readers for RFID transponders and Bluetooth&#xae; devices for for automated roadway tolling and monitoring is described. Because of the ubiquity of Bluetooth&#xae; devices, filtering methods are described to narrow received Bluetooth&#xae; signals to a particular monitored traffic lane and to further associate the Bluetooth&#xae; signal with a registered RFID toll tag in a vehicle. Signal strength of the Bluetooth&#xae; signal at each of a plurality of receiver antennas may be used to identify the location of the Bluetooth&#xae; device that emitted the signal.
