Ban the Cams note:   RLC Vendors (and Cities) routinely use short ambers to keep the violation rates high enough to stay profitable. 

Simply CHANGING AMBERS CAN RADICALLY ALTER THE VIOLATION RATES!  LOOK AT HOW MANY OCCURED under .25 seconds, almost 50% in this Texas study a few years back.  IN GA longer AMBERS were required at ALL RLC intersections.  The change has caused a number of GA towns to drop the RLC. 

Too bad the Florida Legislature DIDN'T put in the MARK WANDALL SCAMERA ACT  a requirement for longer ambers (as well as a citizens vote).

Analysis: Loma Linda yellow lights were illegally short

LOMA LINDA - Nearly 2,000 people received unjustified red-light tickets here in 2006, according to an analysis of city documents.
From the time the city installed red-light cameras in December of 2005 until November of 2006, three intersections had yellow lights set 0.3 seconds shorter than California's legal minimum, the documents show.

The editor of a website devoted to tracking red-light cameras received the documents under a public records request and posted them at www.highwayrobbery.net.

Extrapolating data from March and October of 2006 - the only months released before the change - suggests that about 1,890 drivers received tickets for running a red light by 0.3 seconds or less.

But City Manager Jarb Thaipejr said the city has always followed state requirements.

"Why would we not?" he asked. "I can't speak for what a website says."

Mayor Rhodes Rigsby said he was not aware of any violation but that, in general, he trusted the website and has has taken its advice in the past.

He also said he distrusted the company that operates the cameras and will stop using them when the contract with Redflex expires in December.

"I as the mayor am apologetic to the community for the Redflex camera business that we were associated with," he said. "I hate these cameras more than anyone else in Loma Linda."

He said the city could not refund the fines because its camera-generated profit for the past five years totalled less than $500.
The too-short lights were for eastbound Barton Road at Anderson Street and Barton Road at Mountain View, plus east- and westbound Redlands Boulevard at Anderson Street.

The 45 mph speed limit at these locations means a light must remain yellow for at least 4.3 seconds, according to a Caltrans formula that was also mandatory in 2006. The light was set to 4.0 seconds until November 2006. The lights have since been further lengthened.
