Abstract

An article of manufacture for displaying traffic flow data representing traffic conditions on a road system includes creating a graphical map of the road system which includes one or more segments. The status of each segment on the graphical map is determined such that the status of each segment corresponds to the traffic flow data associated with that segment. An animated traffic flow map of the road system is created by combining the graphical map and the status of each segment.

Claims

1. An article of manufacture for displaying traffic flow data representing traffic conditions on a road system, the article of manufacture comprising a computer-readable medium holding computer-executable instructions for performing a method comprising:

(a) creating a graphical map of the road system, the graphical map including one or more segments;

(b) determining a status of each segment on the graphical map, the status of each segment corresponding to the traffic flow data associated with that segment;

(c) creating an animated traffic flow map of the road system by combining the graphical map and the status of each segment; and

(d) updating the traffic flow data in real-time, the traffic flow map reflecting the updated traffic data, the traffic flow map thereby being updated in real-time, wherein the animated traffic flow map depicts artificial moving images.

2. The article of manufacture of claim 1 wherein the traffic flow data is obtained from roadside sensors.

3. The article of manufacture of claim 1 wherein each segment on the traffic flow map is color coded to reflect its respective status.

4. The article of manufacture of claim 1 wherein each segment on the traffic flow map is animated to reflect its respective status by simulating different vehicle speeds that are representative of actual vehicle speeds.

5. The article of manufacture of claim 1 wherein each segment on the traffic flow map simulates vehicle densities that are representative of actual vehicle densities on the road system.

6. The article of manufacture of claim 1 wherein one or more segments of the traffic flow map are redefined by an end user.

7. The article of manufacture of claim 1 wherein one or more icons corresponding to incident information for one of the segments are placed on the traffic flow map.

8. The article of manufacture of claim 1 wherein the traffic flow map is rendered in video format.

9. The article of manufacture of claim 1 wherein the traffic flow map is rendered in broadcast television format.

10. The article of manufacture of claim 1 wherein the traffic flow map is rendered in cable television format.

11. The article of manufacture of claim 1 wherein the traffic flow map is rendered in satellite broadcast format.

12. The article of manufacture of claim 1 wherein step (a) further comprises creating a graphical map having a plurality of segments.

13. The article of manufacture of claim 1 wherein the traffic flow map shows traffic flow data in both directions of travel.

14. The article of manufacture of claim 1 wherein step (b) further comprises continually determining a status of each segment on the graphical map.

15. An article of manufacture for displaying traffic conditions for a road system on a graphical map, the graphical map including one or more segments, each segment having animated traffic flow corresponding to a status for that link, the article of manufacture comprising a computer-readable medium holding computer-executable instructions for performing a method comprising:

(a) evaluating traffic flow data in real time to determine a status change of one or more of the segments on the graphical map, the status change corresponding to the traffic flow data associated with the one or more segments; and

(b) changing the animated traffic flow of the one or more segments in real time to reflect the status change of the one or more segments, wherein the animated traffic flow depicts artificial moving images.

16. The article of manufacture of claim 15 wherein the traffic flow map is rendered in video format.

17. The article of manufacture of claim 15 wherein the traffic flow map is rendered in broadcast television format.

18. The article of manufacture of claim 15 wherein the traffic flow map is rendered in cable television format.

19. The article of manufacture of claim 15 wherein the traffic flow map is rendered in satellite broadcast format.

20. The article of manufacture of claim 15 wherein the graphical map includes a plurality of segments.

21. The article of manufacture of claim 15 wherein the traffic flow is shown in both directions of travel.

22. The article of manufacture of claim 15 wherein step (a) further comprises continually evaluating traffic flow data in real time to determine a status change of one or more of the segments on the graphical map.

23. An article of manufacture for rendering traffic flow data representing traffic conditions on a road system, the road system including one or more segments, the article of manufacture comprising a computer-readable medium holding computer-executable instructions for performing a method comprising:

(a) providing graphical data of the road system and the corresponding segments;

(b) collecting traffic flow data in real time corresponding to each segment on the road system;

(c) determining a status of each segment, the status corresponding to the traffic flow data associated with that segment; and

(d) inputting the graphical data and the status of each segment into a graphics engine to generate a real-time animated traffic flow map of the road system, wherein the animated traffic flow map depicts artificial moving images.

24. The article of manufacture of claim 23 wherein step (d) further comprises inputting the traffic flow data to the graphics engine for updating the status of the segments.

25. The article of manufacture of claim 23 wherein the traffic flow map is rendered in video format.

26. The article of manufacture of claim 23 wherein the traffic flow map is rendered in broadcast television format.

27. The article of manufacture of claim 23 wherein the traffic flow map is rendered in cable television format.

28. The article of manufacture of claim 23 wherein the traffic flow map is rendered in satellite broadcast format.

29. The article of manufacture of claim 23 wherein the road system includes a plurality of segments.

30. The article of manufacture of claim 23 wherein the traffic flow map shows traffic flow data in both directions of travel.

31. The article of manufacture of claim 23 wherein step (c) further comprises continually determining a status of each segment.
