Last week, the Insurance Institute for Highway Safety published findings that red-light-running violations had declined at intersections with the cameras in Arlington, Va, reports a story in today’s Wall Street Journal.
The study is consistent with other studiesshowing that the cameras make intersections safer, said Anne T. McCartt, co-author of the report and senior vice president for research at IIHS, which is funded by the insurance industry.
“But other researchers question the use of violations as a measure of safety. ‘As soon as you hear them talk about violation rates, these people are trying to obfuscate the fact that accidents don’t go down,’ said Declan O’Scanlon, a New Jersey state assemblyman and an opponent of the cameras.

“The gender of a male CEO’s children is significantly linked to the salary of
his employees, according to new research from Aalborg University economics professor Michael Dahl, University of Maryland Smith School of Business professor Cristian Dezso and Columbia Business School professor David Gaddis Ross. Presented Friday at the annual American Economic Association meeting here, the analysis suggests some explanations for the linkage, but doesn’t draw absolute conclusions.
