I can agree with having them to deter blatant running of red lights. I used to see that in other towns other than my own, and it was REALLY bad. So bad that if you were smart, you would not take off at the green light until you were sure some jackwagon wasn't going to come blasting through the intersection on a red light.
However, many times these are just a revenue generator, as the lights are purposely set to have a very short caution. Many people get caught here as the speed limit is 45, and there is not enough time to stop before the intersection, and the light turns yellow just as they hit the intersection. They then get their picture taken, video has been recorded, and a ticket is automatically sent. Most drivers have no intention to run a red light, and it's not really a fair shake.
