Props to DPL for the quick turn-around!
I've noticed that they have simply removed the signal heads at a few places. Montcalm and Madison used to have a signal but that has been removed (probably ok due to the curent circulation patterns around GCP.
Also, (for instance) McGraw at I96 used to have a signal, but that has been replaced with stop control. If there isn't a warrant for a signal, then technically, based off the michigan manual for uniform traffic control devices, they should be removed so I really don't have a problem with it.
I attribute the fact that so many people run red lights to the fact that are are so many unwarranted signals in the city. One of the major rules for traffic control devices is that they supposed to serve a believable cause (basically saying you cannot sign a freeway with a design speed of 80 mph for 25 mph). If you were to get a ticket for running a light after stopping, I think, with the proper data, you could probably make a case for the signal being illegal.
