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. An integrated traffic control and individual vehicle data collection and analysis system comprising:

a traffic control computer residing in a roadside traffic control system enclosure;

an individual vehicle data collection and analysis application operating on the traffic control computer; and

a sensor positioned above a road,

wherein the traffic control computer is configured to collect a first set of individual vehicle data at a first time, collect a second set of individual vehicle data at a different time, and analyze 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 integrated traffic control and individual vehicle data collection and analysis system of claim 1 further comprising:

an image acquisition system, wherein the individual vehicle data collection and analysis application is further configured to analyze a combination of at least one of the first and second sets of individual vehicle data 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

a traffic control application configured to communicate individual vehicle detection data to the individual vehicle data collection and analysis application.

3. The integrated traffic control and individual vehicle data collection and analysis system of claim 1, wherein the individual vehicle data collection and analysis application is further configured to collect a first set of signal state data at a first time, collect a second set of signal state data at a different time, and analyze 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 traffic control and individual vehicle data collection and analysis system of claim 3 further comprising:

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

5. The integrated traffic control and individual vehicle data collection and analysis system of claim 1 wherein the individual vehicle data collection and analysis application is further configured to collect a set of signal state data and analyze 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.

6. The integrated traffic control and individual vehicle data collection and analysis system of claim 5 further comprising:

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

7. The integrated traffic control and individual vehicle data collection and analysis system of claim 1 wherein:

the individual vehicle data collection and analysis application is further configured to collect concurrent individual vehicle data corresponding to multiple approaches of an intersection and analyze 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

the traffic control computer is further configured to communicate one of the collision and the traffic violation to a vehicle approaching the intersection.

8. The integrated traffic control and individual vehicle data collection and analysis system of claim 7, further comprising:

an image capture system;

wherein the individual vehicle data collection and analysis data analysis system is further configured to characterize 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

wherein the image capture system is configured to capture an image of the intersection in response to characterization of the concurrent individual vehicle data as falling within the known classification.
