Abstract

The present disclosure teaches a software and hardware system capable of operating on a signal controller platform which detects and records individual vehicle data including but not limited to dangerous driving behavior such as red light running and speeding. The disclosure teaches sharing of the computing platform and infrastructure of the traffic control system. The disclosure also teaches receiving, interpreting, and organizing data collected through the traffic control system'"'"'s vehicle detection infrastructure, and driving cameras, video, or other recording devices to provide additional evidence of an individual vehicle'"'"'s behavior.

Claims

1. A method for individual vehicle data trend analysis, the method comprising:

collecting a first set of individual vehicle data;

collecting a second set of individual vehicle data at a different time; and

analyzing, using traffic control computer, a combination of the first set and the second set in order to identify differences and similarities between the two sets and determine whether a number of traffic violations has changed over time.

2. The method of claim 1, further comprising:

analyzing a combination of at least one of the first and second sets of individual vehicle data with and a selected model set of individual vehicle data in order to identify differences and similarities between the analyzed sets and determine whether a number of traffic violations from the one of the first and second sets of individual vehicle data exceeds a number in the selected model set.

3. The method of claim 1, further comprising:

collecting a first set of signal state data;

collecting a second set of signal state data at a different time; and

analyzing a combination of the first set of signal state data and the second set of signal state data in order to identify differences and similarities between the two sets of signal state data and determine whether signal timing has changed over time.

4. The method of claim 1, further comprising:

collecting a set of signal state data; and

analyzing a combination of the collected set of signal state data and a selected model set of signal state data in order to identify differences and similarities between the two sets of signal state data and determine whether signal timing is within a specification of the selected model set.

5. The method of claim 1 further comprising:

collecting concurrent individual vehicle data corresponding to multiple approaches of an intersection;

analyzing a combination of the concurrent individual vehicle data corresponding to the multiple approaches of the intersection to determine whether one of a collision and a traffic violation may occur; and

communicating one of the collision and the traffic violation to a vehicle approaching the intersection.

6. A method for vehicle data trend analysis comprising:

collect a first set of individual vehicle data at a first time, by an individual vehicle data collection and analysis application operating on a traffic control computer in a roadside traffic control system enclosure, using a sensor positioned proximate to a road;

collecting a second set of individual vehicle data at a different time;

analyzing a combination of the first set and the second set in order to identify differences and similarities between the two sets;

and determining, based on the analysis, whether a number of traffic violations has changed over time.

7. The method of claim 6, further comprising:

analyzing at least one of the first or second sets of individual vehicle data in combination with a selected model set of individual vehicle data in order to identify differences and similarities between the analyzed sets and determine whether a number of traffic violations from the one of the first and second sets set of individual vehicle data exceeds a number in the selected model set; and

communicating individual vehicle detection data, using a traffic control application, to the individual vehicle data collection and analysis application.

8. The method of claim 6, further comprising:

collecting a first set of signal state data at a first time;

collecting a second set of signal state data at a different time; and

analyzing a combination of the first set of signal state data and the second set of signal state data in order to identify differences and similarities between the two sets of signal state data; and

determining, based on the differences and similarities, whether signal timing has changed over time.

9. The method of claim 8, further comprising:

communicating the signal state changes to the individual vehicle data collection and analysis application.

10. The method of claim 6, further comprising:

collecting a set of signal state data;

analyzing a combination of the collected set of signal state data and a selected model set of signal state data in order to identify differences and similarities between the two sets of signal state data; and

determining whether signal timing is within a specification of the selected model set.

11. The method of claim 10, further comprising:

communicating signal state changes from a traffic control application to the individual vehicle data collection and analysis application.

12. The method of claim 6, further comprising:

collecting concurrent individual vehicle data corresponding to multiple approaches of an intersection;

analyzing a combination of the concurrent individual vehicle data corresponding to the multiple approaches of the intersection to predict whether one of a collision or a traffic violation may occur; and

communicating, by the traffic control computer, one of the collision or the traffic violation to a vehicle approaching the intersection.

13. The method of claim 12, further comprising:

characterizing the concurrent individual vehicle data as falling within a known classification based on the analysis of the combination of the concurrent individual vehicle data corresponding to the multiple approaches of the intersection; and

capturing an image of the intersection, by an image capture system, in response to characterization of the concurrent individual vehicle data as falling within the known classification.
