Abstract

A distributed individual vehicle information capture method for capturing individual vehicle data at traffic intersections and transmitting the data to a central station for storage and processing is provided. The method includes capturing individual vehicle information at a plurality of intersections (122) and transmitting the individual vehicle information from the intersections to a central station (124). Consequently, the individual vehicle information is available to be stored and processed by a device at the central station (126). Traffic intersection equipment for capturing individual vehicle data at traffic intersections and transmitting the data to a central station for storage and processing is also disclosed. The equipment includes a traffic detection device (159) for capturing individual vehicle data at an intersection (158) and a network connection to a central station (174). The traffic detection device (159) is operably configured to transmit to the central station (174) the individual vehicle information.

Claims

1. A method comprising:

receiving information related to an individual vehicle at a remote detection zone by a processor at a central station, the information including an image scheduled, by the processor at the central station, to be acquired using an image acquisition system and received from the image acquisition system, data received from a vehicle detection sensor, and data received from a traffic signal, where the individual vehicle is associated with the remote detection zone, and the remote detection zone is one of a plurality of remote detection zones from each of which information related to individual vehicles is received at the central station;

combining the image received from the image acquisition system, the data received from the vehicle detection sensor, and the data received from the traffic signal to produce a record related to the individual vehicle;

storing the record related to the individual vehicle at the central station;

analyzing a set of individual vehicle data and signal state data to determine whether a number of traffic violations has increased over a time period to form a set of results, the set of individual vehicle data comprising the record related to the individual vehicle, the signal state data received from the traffic signal; and

making the stored record related to the individual vehicle and the set of results available to internal or external applications.

2. The method of claim 1, wherein the received information related to an individual vehicle includes at least one of individual vehicle speed and individual vehicle classification.

3. The method of claim 1, wherein the received information related to an individual vehicle includes at least one of individual vehicle violation detection and individual vehicle time-stamped position.

4. The method of claim 1, wherein the information related to the individual vehicle includes individual vehicle contact closure information.

5. The method of claim 1, wherein analyzing the set of individual vehicle data and signal state data to determine whether the number of traffic violations has increased over the time period comprises:

comparing individual vehicle data and signal state data for a first period of time with individual vehicle data and signal state data for a second period of time to determine whether the number of traffic violations has increased over the time period.

6. The method of claim 1, wherein the record is a record of the individual vehicle'"'"'s travel up to and through an intersection.

7. The method of claim 1, further comprising predicting a path of travel of the individual vehicle travel up to and through an intersection.

8. The method of claim 1, further comprising at the central station, determining if a traffic violation is likely to occur.

9. The method of claim 1, further comprising at the central station, determining if a safety hazard is likely to occur.

10. The method of claim 1, wherein analyzing the set of individual vehicle data and signal state data to determine whether the number of traffic violations has increased over the time period comprises:

comparing the set of individual vehicle data and signal state data with a model set of data to determine whether the number of traffic violations exceeds a number of violations expected based on the model set of data.

11. A method comprising:

receiving, by a processor at a central station, information related to a first vehicle approaching an intersection and an emergency vehicle approaching the intersection;

receiving, by the processor at the central station, traffic signal status for the intersection;

receiving, by the processor at the central station, a status of the emergency vehicle from the emergency vehicle via a traffic control computer;

predicting a violation by the first vehicle based on the traffic signal status and the information related to the first vehicle; and

communicating the predicted violation to the emergency vehicle wherein the information related to the first vehicle approaching the intersection is recorded by and received from a sensor located proximately to the intersection, wherein the information related to the first vehicle comprises a location, a travel path, a speed, and an acceleration of the first vehicle, and wherein the predicting the violation by the first vehicle comprises;

determining whether a red light violation will occur based on the location, travel path, speed, and acceleration of the first vehicle.

12. The method of claim 11, further comprising analyzing the traffic signal status in conjunction with the information related to the first vehicle and the emergency vehicle.

13. The method of claim 11, wherein the information related to the first vehicle includes detections events of the first vehicle travelling through a first detection zone.

14. The method of claim 11, wherein the information related to the emergency vehicle includes detections events of the emergency vehicle travelling through a second detection zone.

15. The method of claim 11, further comprising predicting travel paths of the first vehicle and the emergency vehicle.

16. A method comprising:

receiving, by a processor at a central station, information related to a first vehicle approaching an intersection and a second vehicle approaching the intersection;

predicting travel paths of the first vehicle and the second vehicle by the processor at a central station;

receiving, by the processor at the central station, traffic signal status for the intersection and a status of the second vehicle;

predicting a violation by the first vehicle based on the traffic signal status and the information related to the first vehicle; and

delaying a planned change of status of a traffic signal based on the predicted violation wherein the information related to the first vehicle approaching the intersection is recorded by and received from a sensor located proximately to the intersection, wherein the information related to the first vehicle comprises a location, a travel path, a speed, and an acceleration of the first vehicle, and wherein the predicting the violation by the first vehicle comprises;

determining whether a red light violation will occur based on the location, travel path, speed, and acceleration of the first vehicle.

17. The method of claim 16, wherein the information related to the first vehicle includes detections events of the first vehicle travelling through a first detection zone.

18. The method of claim 16, wherein the violation prediction is based on the location, travel path, speed, or acceleration of the first vehicle.
