Abstract

A method is provided for providing parking information regarding free parking spaces within at least one city block. The method provides for detecting information regarding available, free parking spaces, wherein a knowledge database with historical data is generated from the detected information. The historical data for specified city blocks and/or specified times or periods of time respectively comprise statistical data regarding free parking spaces. From the historical data and current information that are detected by vehicles in traffic for a first given point in time for a single or a plurality of selected city blocks, a probability distribution of free parking spaces to be expected for the single or the plurality of city blocks is determined. A visualization of the probability distribution is generated that represents the parking information regarding free parking spaces within the single or the plurality of city blocks.

Claims

1. A method for providing parking information regarding free parking spaces within at least a single city block, the method comprising the acts of:

receiving current information regarding available, free parking spaces, wherein a knowledge database with historical data is generated from the information, wherein the historical data respectively comprise statistical data regarding free parking spaces for specified city blocks and/or specified times or periods of time;

fusing the historical data and the current information at a first given point-in-time for at least one selected city block to form fused data,

updating, independently from said fusing, the historical data in the knowledge database with said current information;

determining a probability distribution of the free parking spaces to be expected for the at least one selected city block based on the fused data; and

generating a visualization of the probability distribution that represents the parking information regarding free parking spaces in the at least one selected city block.

2. The method according to claim 1, wherein the current information regarding available, free parking spaces is metrologically detected by vehicles that are in traffic.

3. The method according to claim 2, wherein an edge area alongside a street or roadway is detected by vehicle cameras and an image sequence is generated that is analyzed by a vehicle computer in order to identify free parking spaces alongside the detected edge areas of the street or roadway.

4. The method according to claim 1, wherein the current information regarding available, free parking spaces is detected by sensors that are arranged alongside the city blocks.

5. The method according to claim 1, wherein the current information regarding available, free parking spaces is generated manually by input in an end device.

6. The method according to claim 2, wherein the current information regarding available, free parking spaces is transmitted to a central computer that generates the knowledge database.

7. The method according to claim 1, wherein fusing the historical data and the current information comprises fusing the historical data and the current information using Bayes'"'"' rule.

8. The method according to claim 1, wherein a prognosis of the change of the probability distribution of parking spaces to be expected for a second given point-in-time is determined, wherein the second point-in-time follows after the first given point-in-time, wherein the rate of maneuvering for exiting a parking space (u) and the duration of the search for a parking spot/rate Q are processed to determine the prognosis.

9. The method according to claim 8, wherein the second point-in-time is an arrival time in a destination area that is determined by route navigation comprising the single or the plurality of the specified city blocks.

10. The method according to claim 9, wherein the prognosis is carried out by modeling the probability distribution as determined for the first given point-in-time by an assumed transition to an expected state of the probability distribution, wherein the expected state corresponds to a state that matches the historical data.

11. The method according to claim 8, wherein the prognosis is carried out by modeling the probability distribution as determined for the first given point-in-time by an assumed transition to an expected state of the probability distribution, wherein the expected state corresponds to a state that matches the historical data.

12. The method according to claim 8, wherein the prognosis is generated by a Erlang loss queueing model.

13. The method according to claim 10, wherein the prognosis is generated by a Erlang loss queueing model.

14. A system for providing parking information regarding free parking spaces within at least one city block, comprising:

an information detecting unit configured to detect current information regarding available, free parking spaces so as to generate a knowledge database with historical data based on said detected information, wherein the historical data comprise respective statistical data regarding free parking spaces for specified city blocks and/or specified times or time periods;

a probability distribution determining unit configured to (i) fuse the historical data and current information that are available at a first given point-in-time for at least one selected city block received from vehicles that are in traffic to form fused data, (ii) update, independently from the fused data, the historical data with said current information, and (iii) determine a probability distribution of free parking spaces to be expected for the at least one selected city block based on the fused data; and

a visualization generating unit configured to generate a visualization of the probability distribution that represents the parking information regarding free parking spaces within the at least one selected city block.

15. The system according to claim 14, wherein the information detecting unit comprises vehicles equipped to metrologically detect the information regarding available, free parking spaces.

16. A method for providing parking information regarding free parking spaces within at least a single city block, the method comprising the acts of:

receiving current information regarding available, free parking spaces, wherein a knowledge database with historical data is generated from the information, wherein the historical data respectively comprise statistical data regarding free parking spaces for specified city blocks and/or specified times or periods of time;

fusing the historical data and the current information at a first given point-in-time for at least one selected city block to form fused data,

updating, independently from said fusing, the historical data with said current information;

determining a probability distribution of the free parking spaces to be expected for the at least one selected city block based on the fused data; and

generating a visualization of the probability distribution that represents the parking information regarding free parking spaces in the at least one selected city block,

wherein the current information comprises information regarding maneuvering actions by a vehicle for entering a parking space and/or maneuvering actions by a vehicle for exiting a parking space, wherein a rate of maneuvering for exiting a parking space is determined based on holding times between maneuvering for entering a parking space and maneuvering for exiting a parking space.

17. The method according to claim 16, wherein the current information further comprises information regarding a duration/rate of a search for a parking spot, in that, following the detection of a maneuvering action by a vehicle entering a parking space, location coordinates of a preceding movement of the vehicle and a respective time stamp that is assigned to the local coordinates and momentary velocities are analyzed.
