Automated, i.e constant monitoring, is slightly different than ad-hoc police enforcement, as drivers learn which lights are continually monitored will change behavior, in those locations. Just like known "speed traps" cause people to slow down, or if you use Waze you will slow down if police are reported on the app.

So I have no doubt that automated enforcement will change behavior, I still opposed automated enforcement on a number of grounds, privacy / constitutional / abuse concerns / etc.

Further I would have to look deeper into the implantation, but I know more than a few studies on Red Light cams have shown that while they will reduce intersection crashed, often then INCREASE rear end crashes as people slam on the breaks when the yellow comes on making the intersection not really "safer" it just changes the location of the wreck.

Now for a city like NYC rear end may be safer over all given the high levels of pedestrians I dont know...
