Abstract

A method of monitoring car parking obtains entry data containing at least one entry record, and exit data containing at least one exit record, wherein each entry/exit record contains a vehicle registration number and an entry/exit time. Entry and exit records that have the same vehicle registration number are matched to produce at least one parking record, wherein each parking record contains a vehicle registration number and an indication of a time stayed. Payment data containing at least one payment record is obtained, wherein each payment record contains a vehicle registration number and an indication of a period of time corresponding to a fee paid. For each parking record, either a payment record is identified that has the same vehicle registration number. It is determined whether the indication of time stayed exceeds the period of time in the identified payment record, or if there is no matching payment record identified.

Claims

receive payment data containing at least one payment record, wherein each payment record contains a vehicle registration number and an indication of a period of time corresponding to a fee paid; and

for each parking record, one of;

identify a payment record that has the same vehicle registration number and determine whether said indication of time stayed exceeds said indication of time paid for in said identified payment record, and

identify a condition to the effect that there is no matching payment record.

2. Apparatus according to claim 1, wherein said apparatus is configured to monitor a plurality of car parking sites and each of said entry records, exit records and payment records additionally includes a location.

3. Apparatus according to claim 2, wherein said payment data is produced by at least one payment device having a payment processor, a manual input device, a payment device, an output and a network connection, wherein said payment processor is configured to:

receive a vehicle registration number from said manual input device;

determine a fee paid to said payment device;

calculate an assigned exit time corresponding to said fee;

output said assigned exit time to said output device; and

output said vehicle registration number and said assigned exit time via said network connection.

4. Apparatus according to claim 2, wherein said processor is configured to produce each parking record by:

selecting a first record containing a first registration number and a first time from a first set of records;

selecting a second record containing said first registration number and a second time from a second set of records, wherein said second set does not intersect with said first set;

creating a parking record containing said first registration number, said first time and said second time; and

deleting said first and second records, wherein one of;

said first set of records comprises entry records and said second set of records comprises exit records, and

said first set of records comprises exit records and said second set of records comprises entry records.

5. Apparatus according to claim 4, wherein said processor is configured to select a first record by:

identifying a plurality of records in said first set that contain said first vehicle registration number and times that are within a specified duration of each other,

selecting one of said identified plurality of records; and

deleting the rest of said identified plurality of records.

6. Apparatus according to claim 5, wherein said processor is configured to identify only records from the first set containing the same location.

7. Apparatus according to claim 1, wherein said processor is further configured, upon identifying a condition to the effect that, for a first parking record containing a first vehicle registration number, none of said payment records contains said first vehicle registration number, to:

modify said first vehicle registration number to create a modified first vehicle registration number; and

attempt to identify a payment record that contains said modified vehicle registration number.

8. Apparatus according to claim 7, wherein said processor is configured to modify said first vehicle registration number by substituting a character in said registration number for another character.

9. Apparatus according to claim 7, wherein said processor is configured to modify said first vehicle registration number by swapping the positions of two adjacent characters in said registration number.

10. Apparatus according to claim 1, wherein said entry data and said exit data are downloaded periodically from a server connected to at least one automatic number plate recognition camera.

11. A method of monitoring car parking, comprising the steps of:

obtaining entry data containing at least one entry record, wherein each entry record contains a vehicle registration number, a location and a time;

obtaining exit data containing at least one exit record, wherein each exit record contains a vehicle registration number, a location and a time;

matching entry and exit records that have the same vehicle registration number to produce at least one parking record, wherein each parking record contains a vehicle registration number and an indication of a time stayed;

obtaining payment data containing at least one payment record, wherein each payment record contains a vehicle registration number and an indication of a period of time corresponding to a fee paid; and

for each parking record, attempting to identify a payment record that has the same vehicle registration number and, if a payment record is identified, determining whether said indication of time stayed exceeds the period of time paid for in said identified payment record.

12. A method according to claim 11, wherein a plurality of car parking sites are monitored and each of said entry records, exit records and payment records additionally includes a location.

13. A method according to claim 12, wherein said step of obtaining payment data comprises the steps of:

at a payment device;

receiving an indication of a vehicle registration number;

receiving a fee;

calculating a period of time corresponding to said fee;

producing an indication of said period of time;

storing said vehicle registration number and said period of time as payment data; and

at a central server, obtaining said payment data from said payment device.

14. A method according to claim 11, wherein said step of producing at least one parking record comprises the steps of:

identifying a first record containing a first registration number and a first time from a first set of records;

identifying a second record containing said first registration number and a second time from a second set of records, wherein said second set does not intersect with said first set;

creating a parking record containing said first registration number, said first time and said second time; and

deleting said identified first and second records, wherein one of;

said first set of records comprises entry records and said second set of records comprises exit records, and

said first set of records comprises exit records and said second set of records comprises entry records.

15. A method according to claim 14, further comprising the steps of:

identifying a plurality of records in said first set that contain said first vehicle registration number and times that are within a specified duration of each other;

selecting one of said identified plurality of records; and

deleting the rest of said identified plurality of records.

16. A method according to claim 11, further comprising the steps of:

identifying a condition to the effect that, for a first parking record containing a first vehicle registration number, none of said payment records contains said first vehicle registration number;

modifying said first vehicle registration number to create a modified first vehicle registration number; and

identifying a payment record that contains said modified vehicle registration number.
