Detection and enforcement of failure-to-yield in an emergency vehicle preemption system
First Claim
1. A system for detecting and enforcing violation of traffic laws, the system comprising:
- a transmitter wirelessly transmitting a trigger signal;
at least one image capture device capturing a plurality of images within a view area of the image capture device;
a controller unit in communication with the transmitter and the image capture device, the controller unit receiving the trigger signal and in response, transmitting an image capture command to the image capture device for initiating capture of the plurality of images, the controller unit further tagging a portion of the captured images, the tagged portion including images associated with a violation of a traffic law; and
a processing unit receiving the captured images and analyzing the tagged portion of the captured images, the processing unit automatically issuing a citation for the violation of the traffic law associated with the tagged portion.

Abstract
An intersection controlled by an intersection controller receives trigger signals from on-coming emergency vehicles responding to an emergency call. The intersection controller initiates surveillance of the intersection via cameras installed at the intersection in response to a received trigger signal. The surveillance may begin immediately upon receipt of the trigger signal from an emergency vehicle, or may wait until the intersection controller determines that the signaling emergency vehicle is in the field of view of the cameras at the intersection. Portions of the captured images are tagged by the intersection controller based on tag signals transmitted by the vehicle or based on detected traffic patterns that indicate a potential traffic violation. The captured images are downloaded to a processing facility that analyzes the images and automatically issues citations for captured traffic violations.

12. In a system for detecting and enforcing violation of traffic laws, a controller unit in communication with a vehicle and an image capture device, the controller unit comprising:
-
a receiver wirelessly receiving a trigger signal from the vehicle; means for determining, based on the trigger signal, whether the vehicle is in a predetermined surveillance zone; means for actuating the image capture device in response to a determination that the vehicle is in the predetermined surveillance zone; means for tagging a portion of the captured images, the tagged portion including images associated with a violation of a traffic law; a data store storing the captured images; and means for transmitting the stored images to a processing unit, the processing unit analyzing the tagged portion of the captured images and automatically issuing a citation for the violation of the traffic law associated with the tagged portion. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A computer-implemented method for detecting and enforcing violation of traffic laws, the method comprising:
-
wirelessly receiving a trigger signal from a vehicle; determining, based on the trigger signal, whether the vehicle is in a predetermined surveillance zone; actuating the image capture device in response to a determination that the vehicle is in the predetermined surveillance zone; tagging a portion of the captured images, the tagged portion including images associated with a violation of a traffic law; storing the captured images; and transmitting the stored images to a processing unit, the processing unit analyzing the tagged portion of the captured images and automatically issuing a citation for the violation of the traffic law associated with the tagged portion. - View Dependent Claims (20, 21, 22, 23, 24, 25)
