Red light for red-light cameras?

[Martin Cassini]

A meta-analysis by the Institute of Transport Economics in Norway found that red-light cameras (RLCs) lead to an overall increase in accidents of about 15%. Rear-end collisions went up by about 40%, right angle collisions down by about 10%. It concludes: "RLCs may reduce crashes under some conditions, but on the whole they do not seem to be a successful safety measure."
