Non-violation event filtering for a traffic light violation detection system
First Claim
1. A traffic light violation recording system comprising:
- at least one violation prediction image capturing device, said violation prediction image capturing device providing a plurality of violation images showing a vehicle approaching a traffic signal;
a violation prediction unit, responsive to said at least one violation prediction image capturing device, for generating a prediction that said vehicle approaching said traffic signal will violate a red light phase of said traffic signal; and
a non-violation event filter for determining whether said vehicle is performing a non-violation event.

Abstract
A system and method for detecting and filtering non-violation events in a traffic light violation prediction and recording system, including at least one violation prediction image capturing device, such as a video camera, and a violation prediction unit. The prediction unit generates a prediction reflecting a probability that the vehicle will violate a red light phase of the traffic signal. A non-violation event filter determines whether the vehicle approaching the traffic signal is actually performing a non-violation action. Non-violation events may include a variety of actions performed by the vehicle, and are fully configurable to meet the needs and policies of various specific intersections and jurisdictions. When the non-violation event filter determines that the vehicle is performing a non-violation action, resources that may have been allocated to recording the non-violating vehicle may be released, and a determination may be made that additional resources need not be allocated to such recording.
