Personally, as a driver encountering this kind of signal for the first time (at William and Caroline), I was confused. My first assumption, based on its general location, was that the signal was a malfunctioning pedestrian signal. If I recall correctly, this lit portion of the signal is the lower of two boxes that looks similar to a pedestrian signal. Perhaps when I see both the top and bottom boxes lit while the system is working, it will become more clear.
