## Background
CROSS REFERENCE TO RELATED APPLICATION
This application claims the benefit of U.S. Provisional Patent Application No. 60/604,994, filed Aug. 27, 2004 which is hereby incorporated by reference as if set forth in full herein.


BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to public street parking and more specifically to using Radio Frequency (RF) and Radio Frequency IDentification (RFID) in monitoring and regulating public street parking, using RFID in issuing parking tickets purchased by individuals, and using RFID to identify parking tickets that have expired together with a vehicle parked in a public street parking space.
2. Background
The majority of municipalities use a coin meter for each parking space in public street parking. These coin meters are prone to theft and fraud, require personnel to remove the coins from each meter, and are usually limited to a time frame of 1 to 4 hours.
Currently, to legally park a vehicle in public street parking in many municipalities, an individual must insert coins or tokens into a coin meter located next to a public street parking space in which the individual's vehicle is parked after determining the length of time needed for parking. Municipalities must then rely on the honesty of individuals parking their vehicle in public street parking spaces as well as parking enforcement personnel to properly monitor public street parking and enforce the issuance of parking violation tickets.
A drawback of the present situation is that municipalities lose revenue each time another vehicle parks in a space where time is still available on a meter from a previously parked vehicle or a vehicle is parked in a space with an expired meter and an individual does not pay for parking. In addition, municipalities suffer a decrease in revenues due to the personnel requirements for meter maintenance, violation ticket issuance, and parking space expiration tracking.
An inconvenience to individuals with regard to the present situation is the need to have readily available coins or tokens to use in the coin meters for public street parking. Another disadvantage of the present situation is that if an individual wishes to park their vehicle for a length of time beyond the capabilities of most coin meters (usually 1 to 4 hours) currently in use, the individual must return to the coin meter and reinsert more coins or risk receiving a parking violation ticket.
SUMMARY OF THE INVENTION
This invention allows municipalities to increase revenues, decrease theft and fraud in revenue collection from existing metered parking equipment, and reduce the number of personnel needed for meter maintenance, parking violation ticket issuance, and parking space time monitoring/expiration tracking.
One solution to the present situation is to allow municipalities to issue RFID parking tickets for public street parking without a preset length of time, thereby allowing an individual to determine the amount of time they need for parking. A municipality uses RF technology to issue an RFID parking ticket after an individual purchases an RFID parking ticket for public street parking. After purchasing the RFID parking ticket, the individual places the RFID parking ticket on the vehicle's dashboard near the windshield. A municipality then uses RF technology in conjunction with parking enforcement to monitor and regulate public street parking and parking ticket expiration.
Another solution to the present situation is for municipalities to replace a plurality of existing coin meters with a kiosk including the ways and means to accept cash, coins, Automated Teller Machine (ATM) cards, credit cards, or other Electronic Data Interchange (EDI). This method is beneficial to a municipality in that the municipality can capitalize on the reduction in personnel requirements, theft and fraud. An individual parking their vehicle also benefits with the convenience this invention offers.

DETAILED DESCRIPTION
FIG. 1 is an illustration of a designated parking area, such as a block of public street parking, in a municipality including a kiosk and RFID transceivers in accordance with an exemplary embodiment of the present invention.
As shown in FIG. 1, a kiosk 100 is placed in a readily accessible location on a public street. When an individual parks a vehicle, such as vehicles 102a to 102c, in a public street parking space, the individual must purchase a parking ticket from the kiosk or risk receiving a parking violation ticket. After the individual purchases a parking ticket from the kiosk, the kiosk validates the purchase and prints an RFID parking ticket, such as parking tickets 104a and 104b. The individual returns to the vehicle and places the RFID parking ticket on the vehicle's dashboard near the windshield.
The kiosk is coupled through a wired or wireless local area network 105 to one or more RFID transceivers, such as RFID transceivers 106a to 106c, which are mounted to the curb, sidewalk, or a building in proximity to the public parking space to communicate with an RFID tag or chip which could be present in the form of an RFID parking ticket. The kiosk, components thereof, and associated RFID transceivers are used to interrogate each RFID parking ticket, such as parking tickets 104a and 104b, for validity. Each interrogation from the kiosk may be performed at a defined interval such as every minute, randomly or at the initiation of an event, such as arrival of a new vehicle or request from a parking enforcement official. If an expired RFID parking ticket, such as parking ticket 104b, is identified during the interrogation process, the kiosk having a connection to a central server 108, notifies (110) the central server of the expiration of the RFID parking ticket and its approximate or specific location. The central server, in turn, notifies (111) parking enforcement 112 to dispatch a parking enforcement officer to the location.
FIG. 2 is an illustration of a block of public street parking in a municipality including a:kiosk, RFID transceivers, and vehicle present sensors in accordance with an exemplary embodiment of the present invention.
As shown in FIG. 2, a kiosk 100 is placed in a readily accessible location on a public street. When an individual parks a vehicle, such as vehicles 102a to 102c, in a public street parking space, the individual must purchase a parking ticket from the kiosk or risk receiving a parking violation ticket. After the individual purchases a parking ticket from the kiosk, the kiosk validates the purchase and prints an RFID parking ticket, such as parking tickets 104a and 104b. The individual returns to the vehicle and places the RFID parking ticket on the vehicle's dashboard near the windshield.
The kiosk is coupled is coupled through local area network 105 to sensors, such as sensors 200a to 200c, which can be used to detect the presence of a vehicle, such as vehicles 102a to 102c, in a parking space. The kiosk, sensors, and RFID transceivers can be used to interrogate for the existence of an RFID parking ticket located in a parked vehicle, such as vehicle 102c, which is sensed to be present in a parking space to identify a parked vehicle not having a purchased RFID parking ticket. If the kiosk identifies a parked vehicle not having a purchased RFID parking ticket, the kiosk having a connection to a central server 108, notifies (202) the central server. The central server, in turn, notifies (204) parking enforcement 112 to dispatch a parking enforcement officer to the location.
In addition, the local area network and/or sensors used with the kiosk can be of an optical or proximity nature. The optical or proximity sensing is used to determine if a vehicle is parked in a particular space for which a kiosk is responsible.

As shown in FIG. 3, a kiosk 100 is placed in a readily accessible location on a public street. When an individual parks a vehicle, such as vehicles 102a to 102c, in a public street parking space, the individual must purchase a parking ticket from the kiosk or risk receiving a parking violation ticket. After the individual purchases a parking ticket from the kiosk, the kiosk validates the purchase and prints an RFID parking ticket, such as parking tickets 104a and 104b. The individual returns to the vehicle and places the RFID parking ticket on the vehicle's dashboard near the windshield.
FIG. 3 also illustrates possible locations for one or more cameras, such as cameras 300a to 300c. These cameras are used in conjunction with the kiosk, RFID transceivers 106a to 106c, and sensors 200a to 200c to provide visual signals of illegally parked vehicles, such as vehicle 102c, not having a purchased or valid RFID parking ticket.
Cameras can also be used in one or multiple locations to provide visual recording of vehicles having moved from a parking space after an expired RFID parking ticket was interrogated and identified. In this example, the camera would take a photograph of the license plate of the vehicle.
As shown in FIG. 3, one possible location for a camera would be mounted to a building 302. Another possible location for a camera is within the kiosk 100. Yet another possible location for a camera is on the pole 304 which holds the signal lighting used to control an intersection.
The kiosk is coupled through local area network 105 to sensors 200a to 200c which can be used to detect the presence of a vehicle in a parking space. The kiosk, sensors, and RFID transceivers can be used to interrogate for the existence of an RFID parking ticket located in a parked vehicle which is sensed to be present in a parking space to identify a parked vehicle, such as vehicle 102c, not having a purchased RFID parking ticket. If the kiosk identifies a parked vehicle not having a purchased RFID parking ticket, the kiosk having a connection to a central server 108, notifies (110) the central server. The central server, in turn, notifies (111) parking enforcement 112 to dispatch a parking enforcement officer to the location.
The kiosk is coupled through local area network 105 to RFID transceivers which could be mounted to the curb, sidewalk, or a building in proximity to the public parking space to communicate with an RFID chip which could be present in the form of an RFID parking ticket. The kiosk, components thereof, and associated RFID transceivers are used to interrogate each RFID parking ticket for validity. Each interrogation from the kiosk is performed periodically, aperiodically or on the occurrence of an event. If an expired RFID parking ticket is identified during the interrogation process, the kiosk having a connection to a central server 108, notifies (110) the central server of the expiration of the RFID parking ticket and its approximate or specific location. The central server, in turn, notifies (111) parking enforcement 112 to dispatch a parking enforcement officer to the location.
FIG. 4 is an illustration of an RFID parking ticket depicting logical fields in accordance with an exemplary embodiment of the present invention. Any field or a plurality of fields shown in FIG. 4 could be optional. Additional fields not currently identified may be included on the ticket.
As shown in FIG. 4, an RFID parking ticket 104 includes an RFID tag or chip 400 which provides a unique identity for the parking ticket. This RFID tag or chip could be located anywhere on the parking ticket. The RFID tag or chip is used by a kiosk to record the identity of an RFID parking ticket. Also encoded on an RFID tag or chip is information as to the validity of the time frame associated with a parking ticket by a kiosk comprising the ways and means, along with its local area network of RFID transceivers.
An ID field 402 on the RFID parking ticket provides human readable characters based on the contents of the RFID tag or chip.
A Date In field 404 on the RFID tag or chip is used to identify the date the ticket was purchased. A Time In field 406 is used to identify the time the ticket was purchased. A Date Expire field 408 is used to identify the date the ticket will expire. A Time Expire field 410 is used to identify the time the ticket will expire.
The Date In, Time In, Date Expire, and Time Expire fields are used by a kiosk to link the identity of a ticket to a time frame. These fields are also used during interrogation of an RFID parking ticket to verify the validity of the ticket. If an expired RFID parking ticket is identified during an interrogation process, a kiosk having a connection to a central server notifies the central server of the expiration of the RFID parking ticket. These fields used in conjunction with a Kiosk Location field 414, Public Parking Space Number field 416, and/or Municipality field 418 can be used to identify the approximate or specific location of the vehicle containing the expired RFID parking ticket.
A Purchase Price field 412 is used to identify how much an individual paid for the ticket.
The Kiosk Location field is used to identify the location of a kiosk within a municipality. The Kiosk Location field could also be used to encode the location where a ticket was issued.
The Public Parking Space Number field is used to uniquely identify a public parking space. The Public Parking Space Number field also could be used to associate the RFID parking ticket with a parking space number to prevent the reuse of the RFID parking ticket in a different parking space in another location in the same municipality. Additionally, this field can be used to void a previously purchased RFID parking ticket when another RFID parking ticket associated with a parking space number is purchased for the same parking space number.
The Municipality field could be used to identify the municipality in which a ticket is purchased.
The contents of any of these fields and/or others not currently identified could be recorded on the RFID tag or chip.
FIG. 5 is an illustration of a kiosk and components thereof in accordance with an exemplary embodiment of the present invention. A component or plurality of components shown in FIG. 5 could be optional.
As shown in FIG. 5, a kiosk 100 includes a controller 500 coupled to a memory 501 for storing data about issued parking tickets. The controller is further coupled to an RFID transceiver 502, a printer 504, a card reader 506, a cash or bill acceptor 508, a coin acceptor 510, a camera 512, a connection to a sensor LAN 514, a connection to an RFID transceiver LAN 516, a connection to EDI 518, a connection to a central server 520, a cash return mechanism 522, and a parking violation mechanism 524.
Also shown in FIG. 5 is the controller coupled to an RFID transceiver. During all interrogation processes the controller stores information gathered from the RFID transceiver.
The controller records the identity of a ticket containing an RFID tag or chip when an individual purchases an RFID parking ticket as shown and described in FIG. 4. The controller also enters data in each field of an RFID parking ticket. The controller also identifies expired RFID parking tickets during the interrogation process of RFID parking tickets. The controller also encodes information on an RFID chip as to the validity of a time frame associated with a ticket as well as encoding the location where a ticket was issued. The controller also defines the interrogation process for a defined interval such as every minute.
Alternatively, the controller records the identity a ticket containing an RFID tag or chip when an individual purchases the RFID parking ticket. The controller then enters data in each field of a data record corresponding to the data fields of FIG. 4 with the data record stored in the memory of the kiosk. The controller thus stores information about the RFID chip as to the validity of a time frame associated with the RFID parking ticket as well as storing the location where a ticket was issued.
The controller processes data received from the card reader.
Another component is the RFID transceiver which interrogates each RFID parking ticket to verify the validity of each ticket. The RFID transceiver when coupled with an associated local area network of RFID transceivers interrogates each RFID parking ticket for validity.
An RFID transceiver also interrogates for the existence of an RFID parking ticket located in a parking vehicle which is sensed to be present in a parking space. This interrogation process is to identify a parked vehicle not having a purchased RFID parking ticket.
An RFID transceiver also interrogates each RFID parking ticket located in a parked vehicle to identify a vehicle having an RFID parking ticket purchased from another location with the municipality.
Another component of a kiosk is a printer. The printer coupled with the controller prints an RFID parking ticket when an individual purchases an RFID parking ticket.

The coin acceptor when coupled with a cash return mechanism provides change when an individual inserts a larger denomination of coins or tokens than necessary for the purchase of an RFID parking ticket.
Another component of a kiosk is a camera. The camera when coupled with RFID transceivers provides visual signals of illegally parked vehicles not having a purchased or valid RFID parking ticket. The camera by this method also provides visual recording of vehicles having moved from a parking space after an expired RFID parking ticket was interrogated and identified; for example, by taking a photograph of the vehicle's license plate.
Another component of a kiosk is a connection to a sensor LAN. Sensors coupled to a sensor LAN identify the existence of a vehicles in parking spaces. Sensors coupled to the sensor LAN when coupled with the RFID transceiver LAN interrogate for the existence of an RFID parking ticket located in a parked vehicle which sensors coupled to the sensor LAN identify as being present. This interrogation identifies a parked vehicle not having a purchased RFID parking ticket.
The sensor LAN provides optical or proximity sensors for sensing to determine if a vehicle is parked in a particular space for which a kiosk is responsible.
Another component of a kiosk is a connection to an RFID transceiver LAN. The RFID transceivers coupled to this LAN interrogate RFID parking tickets to verify the validity or expiration of each ticket. The RFID transceivers when coupled to the RFID transceiver LAN to a sensor LAN identify a parked vehicle not having a purchased RFID parking ticket. The RFID transceivers by this method also identify a vehicle having an RFID parking ticket purchased from another location within the municipality or a different municipality.
A RFID transceiver when coupled with a camera identifies illegally parked vehicles not having a purchased or valid RFID parking ticket.
Another component of a kiosk is a connection to EDI where upon after receiving a request by an individual to purchase an RFID parking ticket, EDI processes and validates the purchase if the purchase was made using ATM, credit card, or other EDI.
The connection to EDI is coupled with a card reader where after ATM, credit card, or other EDI is inserted into a card reader, EDI processes and validates the purchase.
Another component of a kiosk is a connection to a central server, the central server comprising the ways and means necessary to monitor the kiosk and track public parking activity. Information such as expired RFID parking ticket notification, illegally parked vehicles not having a purchased RFID parking ticket, and vehicles having an RFID parking ticket purchased from another location is passed from a kiosk to a central server using the connection to a central server.
Another component of a kiosk is a cash return mechanism. The cash return mechanism when coupled with a cash acceptor dispenses change when an individual inserts a larger denomination of currency than necessary for the purchase of an RFID parking ticket.
The cash return mechanism when coupled to a coin acceptor provides change when an individual inserts a larger denomination of coins or tokens than necessary for the purchase of an RFID parking ticket.
Another component of a kiosk is a parking violation mechanism which includes the ways and means to accept payment from an individual for a parking violation ticket.
