I think you may want to read the article again.

The mandated increase in signal time created dramatic and instant results. In 2008, Lasercraft issued an average of 1,559 citations each month. In January, that number dropped 80 percent to just 313. Norcross also saw an 80 percent drop in violations.

According to a 2001 report by the Office of the U.S. House Majority Leader, the findings in Lilburn and Norcross are not coincidental. The report argued that changes in national signal timing guidelines systematically reduced the amount of warning time available to motorists. It argued further that those with a financial incentive in using enforcement to deal with the additional violations created may have played a role in the changes(view report).

How about eliminating the arbitrary reduction in yellow light timing which was conducted with a financial incentive.

I read the article and did not see anything in it about what the original time was (nor the altered time) when compared with the time calculated by the traditional formula.

I have read several threads about Red Light cameras posted here and it seems like most of the posters are totally unaware that a formula exists and should be used with or without red light cameras.
