Abstract

Disclosed here are system, apparatus, article of manufacture, method and/or computer program product embodiments for track association. An embodiment operates by receiving a first set of track identification data from a first tracking system. The first set of track identification data is associated with a global track identifier (GID). The first set of track identification data associated with the GID is broadcasted to the first tracking system and a second tracking system. A second set of track identification data is received from the second tracking system. The second set of track identification data identifies any tracks of the second tracking stystem that match the first set of track identification data. The GID is associated with the second set of track identification data.

updating, in the database, the linked relationship based on the association.

3. The method of claim 2, wherein updating the linked relationship comprises:

generating links between the first set of track identification data, the second set of track identification data and the respective local track identification data based on the GID.

4. The method of claim 2, further comprising:

broadcasting the updated linked relationship to the plurality of tracking systems;

analyzing the additional mapping data; and

updating the database based on the analysis.

5. The method of claim 4, further comprising:

receiving from at least one tracking system of the plurality of tracking systems, an indication of a disagreement with the broadcasted updated linked relationship, wherein the disagreement is based on differences between characteristics of a local track of the at least one tracking system and the broadcasted updated linked relationship;

modifying the updated linked relationship for the at least one tracking system based on the disagreement, wherein the local track is assigned a different GID; and

broadcasting the modified linked relationship for the at least one tracking system, including the different global track ID, to the plurality of tracking system.

6. The method of claim 4, wherein the analyzing comprises:

identifying at least one of new track data and updated track data; and

the updating comprises;

generating a new linked relationship when new track data is identified; and

further updating the linked relationship when updated track data is identified.

7. The method of claim 6, wherein the updating further comprises:

removing associations between a previously assigned GID and respective local track identification data; and

assigning the respective local track identification data to another GID.

8. A system comprising:

a memory; and

at least one processor coupled to the memory and configured to;

receive a first set of track identification data from a first tracking system;

associate the first set of track identification data with a global track identifier (ID) to generate a local track ID to global track ID (GID) pairing;

broadcast, to the first tracking system and a second tracking system, the first set of track identification data and the local track ID to GID pairing;

receive, from the second tracking system a second set of track identification data, wherein the second set of track identification data identifies a track of the second tracking system that matches the first set of track identification data; and

associate the GID with the second set of track identification data that matches the first set of track identification data.

9. The system of claim 8, the at least one processor further configured to:

maintain, in the memory, a linked relationship between the first set of track identification data and the second set of track identification data based on the GID;

broadcast the linked relationship to a plurality of tracking systems including the first tracking system, the second tracking system and additional tracking systems;

receive, from the plurality of tracking systems, respective mapping data, wherein the mapping data links respective local track identification data with the GID;

associate, in the memory, the GID with the respective local track identification data; and

update, in the memory, the linked relationship based on the association.

10. The system of claim 9, the at least one processor further configured to:

generate links between the first set of track identification data, the second set of track identification data and the respective local track identification data based on the GID.

11. The system of claim 9, the at least one processor further configured to:

broadcast the updated linked relationship to the plurality of tracking systems;

receive, from the plurality of the tracking systems, additional mapping data;

analyze the additional mapping data; and

update the database based on the analysis.

12. The system of claim 11, the at least one processor further configured to:

receive, from at least one tracking system of the plurality of tracking systems, an indication of a disagreement with the broadcasted updated linked relationship, wherein the disagreement is based on differences between charateristics of a local track of the at least one tracking system and the broadcasted updated linked relationship;
