When red-light cameras are installed at an intersection, the number of rear-end accidents typically increases as drivers unexpectedly slow down instead of speeding up at yellow lights.
The cost of these accidents is borne by just about everyone, except the authority profitably operating the red lights. (To be fair, some statistics also show a decrease in right-angle collisions, which is kinda the point of the red-light rules to begin with.)
That seems only like a temporary problem until people get used to actually stopping at red lights, as they are supposed to. After the initial acceptance phase, it should minimise accidents over the longer term.
Unless there is a warning of how long is left on the yellow light, it’s an unsolvable problem because there is an asymmetric risk of stopping vs accelerating

This just sounds like everyone is speeding and/or distracted.
The lights should be designed so that if you don't have enough space to stop with a mild deceleration you should just go through. If a mild deceleration get you rear ended then of course that's an unsolvable problem

>speeding up at yellow lights
I remember reading somewhere accelerating at orange light is actually a ticket-able offense?
My memory may be outdated or only local to my jurisdiction but my understanding is that yellow means “do not enter the intersection” where “intersection” begins before the box, usually with some alternate street indicator, like broken white lines turning to solid, at a braking distance that accounts for posted speed limit and yellow light duration.
