Machines
Traffic signals are machines. They have at least two and often more computers inside a box near the signal that are programmed to turn the light bulbs on and off. Because of their complexity, they can fail in a varied number of ways. Some fail into a state where they flash red or yellow rather than control traffic. Other ways include failing in a totally dark state. More ominious is the programming. Improper programming or a glitch that modifies the program can allow the signal to continue to operate even though it no longer is following the intended operation.
Another machine
Now add another machine. This machine is designed to recognize when a vehicle has passed a particular point after the signal has turned red. This machine is as or more complex than the traffic signal. It involves computers, sensors, cameras, wiring and all other other accompanyments of a complex device. It too can fail.
My experience
I am expert in the operation of traffic signals. For twelve years I supervised a network of fifty traffic signals. I became expert not only in maintaining the signals, but in the operation of the hardware and software that define the signals. I became expert at signage and many of the engineering requirements necessary for proper traffic flow. This experience is invaluable in assessing the proper application of criminal law when a client has been charged with signal or sign issue.
My approach
If retained on a red light camera citation my first task is to analyze the operation of the traffic signal. This means I must document the physical structure, the programming and how traffic reacts to the signal. I must compare the on-street programming to best practices to see if the programming is proper.
I then analyze the camera computers to try to determine if they are properly positioned, programmed and responding to the traffic flow.
At that point I can provide you with an understanding of your case. Give me a call.
