Red Light Camera Short Yellow Photo Enforced Intersection

If you want to demonstrate the exact timing, you need to run a stopwatch on the entire sequence, then go back and capture the first frame of video where it goes yellow and note the time. Note the time again at the first frame of red light, and use the difference between times to identify the true length of the signal, eliminating your reaction time. You said yourself, it takes a human one second to recognise a signal change.

I timed the steady yellow signal in your video by downloading, viewing and replaying using a video editor with an electronic stop watch. The steady yellow interval was 3.137 seconds. You were nine tenths of a second late starting the stop watch and about four hundredths of a second late in stopping it. I used to time the signals the same way but found out video was much more accurate. Most cities don't use video to check the timing so they are off too. theticketdoctordotnet.

@MrBFagel Thats a good idea you have there. What was your results for yellow lights with cams vs yellow lights without?

For the sake of accuracy, you're better off just letting the stop light run once it's green, then take a freeze-frame shot of the time when it hits yellow, same on red, and subtract.

watching the video, your timing is about 1 second+ late.

@westonmwhite timing is on. You can go try it.

@djrichardblanc

No, your timing in starting the clock was a second late. I would say from estimating, it was probably a 3 second yellow, which is still pretty ridiculous. Your point is noted that the yellow is ridiculously short. But it is slighting longer than what you were indicating here.

BIG BROTHER is not only watching, but broke.
