* Camera installation is usually accompanied by shortening the yellow light period to increase revenue, which leads to more accidents.
* Most red light camera tickets are for rolling right turns on red. Such a violation rarely leads to accidents. These tickets are more for revenue than safety.
Did you read the article?
The problem is that the speed limit doesn't correlate with accidents. The speed variance (or spread) however does correlate with accidents.
So, what the article says, very politely, is that the schmucks who regard the speed limit as an actual limit cause more accidents than the people driving at the consensus average.
And, just so you know, most people don't object to red light cameras for public safety. There are dangerous intersections where a red light camera would be quite appropriate.
However, much like speed limits, red light cameras seem to grow on revenue producing intersections with low fatality rates but a mis-engineered light sequence while somehow missing intersections which actually are low-volume but very dangerous.
Traffic citations should have the ultimate goal to increase the level of safety on roadways. Revenue should play no part in it.
A better proposal would be to remove all fines and court costs associated with a traffic citation and change the penalty to only be demerit points on the offender's drivers license. If they accumulate enough points, then their license is suspended. If they're caught driving on a suspended license, they're arrested and go to jail pending a hearing.
That is a bad idea, because then the traffic arrangements will drift to be optimized for revenue generation, not safety nor fluent traffic.
That's not what the article is saying. The best way to put it is to say that "people are going to run red lights anyway, so make the yellow light longer so that less people will run red lights".
Ticket them and make money for the municipality. Don't engineer new solutions that cost tax payers money and make rodes less safe for people not in cars.
