Abstract

Technologies and techniques for quality determination for a traffic system. First traffic parameter data is acquired from the traffic system, indicative of a parameter of the traffic system. Second traffic parameter data is acquired, indicative of another parameter of the traffic system, wherein the second traffic parameter data originate from a plurality of traffic participants. The parameter from the first traffic parameter data and second traffic parameter are obtained, wherein the parameter obtained from the first traffic parameter data is compared to the parameter obtained from the second traffic parameter data in order to determine the quality of the first traffic parameter data.

First claim

The invention claimed is:

1. A method for determining quality of signals for a traffic system comprising:
acquiring first traffic parameter data from the traffic system indicative of a parameter of the traffic system;
acquiring second traffic parameter data indicative of the parameter of the traffic system, wherein the second traffic parameter data originate from a plurality of traffic participants;
obtaining the parameter form the first traffic parameter data;
obtaining the parameter form the second traffic parameter data;
comparing the parameter obtained from the first traffic parameter data to the parameter obtained from the second traffic parameter data in order to determine the quality of the first traffic parameter data; and
adjusting a route guidance based on the parameter.

2. The method of claim 1 , further comprising:
determining the quality of the first traffic parameter data based on the comparison; and
deciding, based on the quality, whether the first traffic parameter data are to be considered in a future use of the traffic system.

3. The method of claim 1 , wherein the comparing comprises determining a statistical deviation of the parameter obtained from the first traffic parameter data from the parameter obtained from the second traffic parameter data.

4. The method of claim 1 , wherein the parameter comprises at least one traffic control information, comprising a traffic light phase, and associated with a lane information.

5. The method of claim 4 , wherein the parameter further comprises an anticipated phase change of the traffic light phase.

6. The method of claim 5 , further comprising predicting the anticipated phase change, based on the parameter obtained from the first traffic parameter data when the quality is above a predetermined threshold.

7. The method of claim 6 , further comprising adjusting a speed of a vehicle based on the predicted phase change.

8. The method of claim 1 , wherein the second traffic parameter data comprises swarm data.

9. The method of claim 1 , wherein the first traffic parameter data comprises one or more of a signal phase, time data, and/or road topology data.

10. A quality determining device for a traffic system comprising:
a network interface for acquiring first traffic parameter data from the traffic system indicative of a parameter of the traffic system;
an image capturing device for acquiring second traffic parameter data indicative of the parameter of the traffic system, wherein the second traffic parameter data is associated with a plurality of traffic participants;
a processing device, operatively coupled to the image capturing device and network interface, wherein the processing device is configured to
obtain the parameter from the first traffic parameter data;
obtain the parameter from the second traffic parameter data;
compare the parameter obtained from the first traffic parameter data to the parameter obtained from the second traffic parameter data in order to determine the quality of the first traffic parameter data; and
adjust a route guidance based on the parameter.

11. The quality determining device of claim 10 , wherein the processing device is configured to:
determine the quality of the first traffic parameter data based on the comparison; and
decide, based on the quality, whether the first traffic parameter data are to be considered in a future use of the traffic system.

12. The quality determining device of claim 10 , wherein the processing device is configured to compare by determining a statistical deviation of the parameter obtained from the first traffic parameter data from the parameter obtained from the second traffic parameter data.

13. The quality determining device of claim 10 , wherein the parameter comprises at least one traffic control information, comprising a traffic light phase, and associated with a lane information.

14. The quality determining device of claim 13 , wherein the parameter further comprises an anticipated phase change of the traffic light phase.

15. The quality determining device of claim 14 wherein the processing device is configured to predict the anticipated phase change, based on the parameter obtained from the first traffic parameter data when the quality is above a predetermined threshold.

16. The quality determining device of claim 15 , wherein the processing device is configured to adjust a speed of a vehicle based on the predicted phase change.

17. The quality determining device of claim 10 , wherein the second traffic parameter data comprises swarm data.

18. The quality determining device of claim 10 , wherein the first traffic parameter data comprises one or more of a signal phase, time data, and/or road topology data.

19. A vehicle of a traffic system, comprising:
a quality determining device, comprising (i) a network interface for acquiring first traffic parameter data from the traffic system indicative of a parameter of the traffic system, and (ii) an image capturing device for acquiring second traffic parameter data indicative of the parameter of the traffic system, wherein the second traffic parameter data is associated with a plurality of traffic participants;
a processing device, operatively coupled to the image capturing device and network interface of the quality determining device, wherein the processing device is configured to
obtain the parameter from the first traffic parameter data;
obtain the parameter from the second traffic parameter data;
compare the parameter obtained from the first traffic parameter data to the parameter obtained from the second traffic parameter data in order to determine the quality of the first traffic parameter data; and
adjust a route guidance based on the parameter.

20. The vehicle of claim 19 , wherein the processing device is configured to:
determine the quality of the first traffic parameter data based on the comparison; and
decide, based on the quality, whether the first traffic parameter data are to be considered in a future use of the traffic system.
