As much as I don't like the "red light cameras" in boulder that get people during the yellow caution lights (even my friend who is a cop has had three tickets in a patrol car and has had to pay them, and I've gotten a few), this may be a good idea if its in construction zones, but I think only when people are actively working or it is an unsafe area for higher speeds. Highway 66 has been under construction for a VERY long time and near I-25 there have been fatal accidents. I drive through there twice a week in my work truck. Its road rage central and people are always passing the cars illegally that are going FASTER than the work zone speed limit without regard of the "fines doubled" signs. But some "construction areas" like Prospect road just west of I-25 earlier this year, it always had signs it was a construction area but people were never working, so it was pretty hard to drive 35 through that stretch.
I have a progam on my GPS unit that alerts me to speed cameras and red light cameras just to "remind me" but I still try to follow the speed limit, epseically in construction areas. But I hope it does not turn into something that is abused like the red light cameras in Boulder. Those are just stupid and nothing more than a way to generate money. I would much rather see more troopers doing more over time in construction areas, or doing something like the photo radar vans that Boulder Police has, rather than a fixed unit that would be snapping pictures of every motorist. Officers and Troopers use thier discression when writing tickets, and thats not something that would be done with a photo unit obviously, unless they had a complex program for it.
They do need to find ways to slow down people in active construction zones, though.
