Abstract

A method and system for combining short range communication and long range communication for traffic related applications is presented. In one example, a central server is equipped and configured to receive information via long range communication from one or more individual traffic objects, analyze the received information to determine the short range communication needs, if any, between an identified subset of traffic objects and then initiate short range communication between the traffic objects in the identified subset of traffic objects.

Claims

1. A system, comprising:

a plurality of individual traffic objects within a group of traffic objects being configured for communication with one another over short range communication technology; and

a central server configured for communication with one or more of said plurality of individual traffic objects over long range communication technology, said central server being configured for receiving information from one or more of said plurality of individual traffic objects, analyzing said received information, determining short range communication needs between an identified subset of traffic objects and initiating short range communication between said identified subset of traffic objects.

2. The system as defined in claim 1 further comprising the central server receiving sensor data information from one or more of said individual traffic objects.

3. The system as defined in claim 1 further comprising the central server receiving information for initiating ad-hoc short range communication between traffic objects.

4. The system as defined in claim 1 further comprising initiating ad-hoc short range communication between traffic objects via short range radio identification (ID) information.

5. The system as defined in claim 1 further comprising the central server sending short range radio identification (ID) information to the identified subset of traffic objects for the traffic objects short range communication.

6. The system as defined in claim 2 wherein said sensor data information includes information about others of said plurality of individual traffic objects within said sensor sensing distance of a said individual traffic objects and information about the position and trajectory of said individual traffic object.

7. The system as defined in claim 1 wherein said individual traffic object is configured to request and accumulate sensor data information from others of said plurality of individual traffic objects.

8. The system as defined in claim 1 wherein said individual traffic object is configured to evaluate if an individual traffic object trajectory is on course leading to a potential collision with said individual traffic object.

9. The system as defined in claim 4 wherein one or more of said plurality of individual traffic objects are configured and arranged with imaging capability to sense individual traffic objects within said sensor sensing distance of a said individual traffic object to provide in real time a graphic representation of said individual traffic objects within said sensor sensing distance in said area of interest or concern.

10. The system as defined in claim 9 wherein said real time graphic representation is shared with others of said plurality of individual traffic objects over said ad hoc short-range communication network.

11. Method, comprising:

communicating via long range communication technology between a central server and one or more traffic objects in a set of individual traffic objects for receiving the traffic-related information;

analyzing the traffic-related information;

determining the short range communication needs between traffic objects in an identified subset of individual traffic objects; and

initiating short range communication between traffic objects in said identified subset of individual traffic objects for providing a complete traffic scene of the area of interest or concern.

12. The method as defined in claim 11 comprising the central server receiving sensor data information from one or more of said individual traffic objects.

13. The method as defined in claim 11 comprising the central server receiving sensor data information from one or more of said individual traffic objects each of which has collected sensor data information from one or more of others of said individual traffic objects, the central server initiating ad-hoc short range communication between others of said traffic objects in an identified subset of individual traffic objects.

14. A computer program product comprising a computer readable storage structure embodying computer program code thereon for execution by a computer processor, wherein said computer program code comprises instructions for performing a method according to claim 11.

15. An application specific integrated circuit configured for operation according to claim 11.

16. Apparatus, comprising:

a traffic object arranged with a suitable short-range communication technology and a suitable long range communication technology, configured for providing traffic related information via said long range communication technology and further configured for receiving instructions via said long range communication technology for initiating short range radio communication with other traffic objects.

17. The apparatus as defined in claim 16 comprising said traffic object further

configured for long range communication with a central server.

18. Apparatus, comprising:

a traffic object arranged with a suitable short-range and/or a suitable long range communication technology and with at least one camera for image and/or video capturing functionality configured for receiving further image/video information via said short range communication technology and/or said long range communication technology and for computing said captured and said received image/video information for generating a traffic scene around said traffic object.

19. Apparatus as defined in claim 18 wherein said traffic object is further configured for transmitting and/or receiving further sensor information including one or more of speed, position and distance to other traffic objects.
