So I find this interesting; and, I'm glad they provided at least this statistic:

   Vehicle crashes near cameras declined 3.9%
   Crashes with injuries near cameras declined 13.4%
If that's the case, I'm pleased. That's a noticeable decline. I wonder what else could be done to safely reduce the number of crashes, while still allowing drivers the freedom to drive.

Another interesting piece:

Referring to 'The Busy Crossing', "This is the kind of location one might expect for a speed camera. They target busy crossings near some of the city's most dangerous boulevards. These cameras are more common than the "speed traps" but they issue far fewer tickets."

I imagine knowing that there is a speed camera near a given light reduces the amount of people willing to test that. When it comes to traffic lights and busy crossings, I think this is a good thing; and not having very many tickets there should by no means be indicative of the systems failing. In fact, I would argue they might be working. You'd have to do a blind test of some sort with unmarked cameras (that don't give out tickets either) at other locations; but ... that's most likely illegal. (IANAL)

And then regarding this:

"Almost half of the city's speed cameras are mobile — mounted on NYPD vehicles, they watch different spots for a day or two. Officials won't say how those spots are picked, though school principals and community groups can make requests. The mobile cameras each issue just a few tickets a day; as a group they issue only 11.5% of all tickets."

That's to be expected. It's a camera mounted to a police vehicle. People tend to act more civil on the road and more accurate to the rules when there's a police officer around.

Personally, I'd love to find out the statistics around red-light cameras, as well. I imagine they might be even more useful in quelling negative activity (though they probably won't bring in as much money as speeding cameras)




There's a study on red light cameras in Chicago that shows some interesting data about what affects they have on driving behaviour and accident rates

Or perhaps it's just the old phrase "Lies, damned lies, and statistics" that is appropriate once again?

That was absolutely brilliant! Thank you for sharing!
