Abstract

A system and method for ranking the relative movement of objects on a pathway is provided. The method includes: dividing the pathway into a plurality of sectors, each sector having a rank of order with respect to a beginning and an ending point of the pathway; receiving coordinate data from each of the objects; identifying, based on the received coordinate data, if any objects are present in individual ones of the plurality of sectors; determining, for any sector that has at least two objects, the positional order of the at least two objects within that sector; and ranking the positional order of the plurality of objects along the pathway based upon the rank order of the sector in which each object is present, and which multiple objects that are present in any sector are ordered as set by the determining.

Claims

1. A method for ranking the relative movement of objects on a pathway, comprising:

dividing the pathway into a plurality of sectors, each sector having a rank of order with respect to a beginning and an ending point of the pathway;

receiving coordinate data from each of the objects;

identifying, based on the received coordinate data, if any objects are present in individual ones of the plurality of sectors;

determining, for any sector that has at least two objects, the positional order of the at least two objects within that sector; and

ranking the positional order of the plurality of objects along the pathway based upon the rank order of the sector in which each object is present, and which multiple objects that are present in any sector are ordered as set by the determining.

2. The method of claim 1, wherein the pathway defines a closed loop that the plurality of objects will repeatedly travel over a number of laps, the plurality of sectors covering a single lap of the number of laps, the method further comprising:

identifying those of the plurality of objects that are in a first particular lap;

performing the identifying and determining only for those of the plurality of objects that are associated with the first particular lap, while disregarding others of the plurality of objects that are associated with a different lap;

wherein the ranking the positional order of the plurality of objects along the pathway is based upon a rank order of the number of laps, within each lap the rank order of the sectors in which each object is present, in which multiple objects within any sector for any common lap are ordered as set by the determining.

3. The method of claim 1, wherein a forward edge of a highest ranking sector of the plurality of sectors aligns with a predetermined end of the pathway.

4. The method of claim 1, wherein the pathway includes a start line and a finish line, a forward edge of a highest ranking sector of the plurality of sectors aligns with the finish line, and a rearward edge of the lowest ranking sector of the plurality of sectors aligns with the start line.

5. The method of claim 4, wherein the pathway defines a loop, and the start line and the finish line are the same line.

6. The method of claim 1, further comprising visually displaying the positional order as established by the ranking.

7. The method of claim 1, further comprising recursively performing the receiving, identifying, determining, and ranking steps, such that the positional order of the objects as they move along the pathway is monitored and updated.

8. The method of claim 1, wherein the recursively performing occurs in near real-time.

9. The method of claim 1, wherein the determining comprises determining from the received coordinate data the distance of each of the at least two objects to a forward edge of the sector, and ordering the at least two objects based upon the shortest to longest distance.

10. The method of claim 1, wherein the determining comprises determining from the received coordinate data the distance of each of the at least two objects to a rear edge of the sector, and ordering the at least two objects based upon the longest to shortest distance.

11. The method of claim 1, the ranking further comprising:

for each sector, recursively in rank order sequence from the highest to the lowest, listing the objects in each sector to collectively provide a priority order list of the objects for the plurality of sectors.

12. The method of claim 1, the ranking further comprising:

for each sector that includes an object, recursively in rank order sequence from the highest to the lowest, listing the objects in each sector to collectively provide a priority order list of the objects for the plurality of sectors.

13. The method of claim 1, wherein the pathway has at least one branch.

14. The method of claim 1, wherein the branch is a pit area with an entrance and an exit that connects to the pathway, and the dividing step includes the pit area.

19. The method of claim 1, further comprising visually displaying the positional order of the objects as established by the ranking.

15. A method for ranking the relative movement of objects that are lapping a pathway, comprising:

dividing the pathway into a plurality of sectors, each sector having a rank of order with respect to a beginning and an ending point of the pathway;

identifying, for each object on the track, a lap in which the object is in and which of the plurality of sectors the object is in;

determining, for any sector that has multiple objects in a common lap, the position order of the multiple objects within that sector and common lap; and

generating a positional order of the objects along the pathway based upon the rank order of the lap in which each object is present, within each lap the rank order of the sector in which each object is present, and which multiple objects within any sector within a common lap are ordered as set by the determining.

16. The method of claim 15, wherein a forward edge of a highest ranking sector of the plurality of sectors aligns with a predetermined end of the pathway.

17. The method of claim 15, wherein the pathway includes a start line and a finish line, a forward edge of a highest ranking sector of the plurality of sectors aligns with the finish line, and a rearward edge of the lowest ranking sector of the plurality of sectors aligns with the start line.

18. The method of claim 17, wherein the pathway defines a loop, and the start line and the finish line are the same line.

20. The method of claim 15, further comprising recursively performing the receiving, identifying, determining, and generating steps, such that the positional order of the objects as they move along the pathway is monitored and updated.

21. The method of claim 15, wherein the recursively performing occurs in near real-time.

22. The method of claim 15, wherein the determining comprises determining from the received coordinate data the distance of each of the at least two objects to a forward edge of the sector, and ordering the at least two objects based upon the shortest to longest distance.

23. The method of claim 15, wherein the determining comprises determining from the received coordinate data the distance of each of the at least two objects to a rear edge of the sector, and ordering the at least two objects based upon the longest to shortest distance.

24. The method of claim 15, wherein the pathway has at least one branch.

25. The method of claim 15, wherein the branch is a pit area with an entrance and an exit that connects to the pathway, and the dividing step includes the pit area.

26. A method for ranking the relative movement of objects that are lapping a race pathway, comprising:

dividing the pathway into a plurality of sectors, each sector having a rank of order with respect to a beginning and an ending point of the pathway;

receiving coordinate data from each of the objects;

establishing the highest current n^th lap in the race, where n is an integer;

recursively for each k^th lap in order from n to a lowest lap;

identifying any of the objects in the k^th lap;

recursively for each sector, in order from a highest ranking sector to a lowest ranking sector;

identifying whether any of the objects within the k^th lap are within the sector; and

if multiple objects are in the sector, determining a positional order of the multiple objects within the sector;

displaying the positional order of the objects along the pathway in lap and sector order, including order of multiple objects within a sector pursuant to the determining.
