Did Univeristy student in Columbus RLC "violation" times review video or just used "time into red"????
Recently a report came out of Columbus on RLC. A Univeristy student used data "provided" by Redflex and the city that "40% of those caught by cameras missed by at least three seconds." http://www.dispatch.com/content/stories/local/2012/01/15/red-light-offenses-arent-all-close.html
Quote: He studied six years of records kept by the Department of Public Safety and Redflex Traffic Systems, the Arizona company that operates Columbus cameras.
“In my opinion, they’re blatantly running a red light,” Brunner said.
About half the drivers caught by red-light cameras entered intersections less than a second after signals turned red, Brunner’s study found.
(Also mentioned in the article was the fact that Amber was increased at another intersection that resulted in a 40% drop in "violations").
[He goes on about less crashes where he doesn't even break out RLV crashes from the angles. Think he just trusted what was given to him by the vendor and city? The last time a Redflex city tried to claim LESS crashes was Chicago. Lets just say the city's claims were less than complete. http://www.myfoxchicago.com/dpp/news/metro/red-light-cameras-chicago-crashes-accidents-20100607
So what wasn't mentioned was what did the NON camera intersection do and what was the "defintion" of a crash: type, dollar amount, distance, reportable or not. see: http://www.banthecams.org/1946-six-examples-of-misleading-the-public-safety-claims-by-towns-who-use-ats.html It might be another vendor, but the games are the same.)]
The last time someone looked closely at time into red was the TTI study in 2004. http://www.thenewspaper.com/news/02/243.asp
In that Study the VAST MAJORITY of the "violations" were under 1 second. See Chart below.
Even a 2001 CA State Auditor report found 77% of RLC tickets were for split second violations. http://www.thenewspaper.com/news/29/2934.asp http://www.thenewspaper.com/news/01/116.asp http://www.thenewspaper.com/rlc/docs/02-ca-audit.pdf
What isn't mentioned in the Columbus article is whether the student REVIEWED EVERY SINGLE VIOLATION in video or NOT. Or did he just take the vendors "time into red" as "proof".
You see when the 2004 study was done by TTI, citing for stopping on the stop line and right turns on red were not as commonly done. Now most vendors do it routinely. Reports of Redflex doing this started showing up in 2005. http://www.thenewspaper.com/news/02/225.asp (IN fact the earliest report of citing for stopping on the stop line was 3/2006 that I could find. http://www.thenewspaper.com/news/10/1040.asp)
A RLC ticket will have time into red on it. Like this one below for stopping over the stop line. http://www.thenewspaper.com/news/36/3687.asp
I bring this up for one reason, if the students study INCLUDED right turns on red and stop line "violations" IT WILL SKEW THE PLUS 3 second NUMBER!
Most Right Turns on red are well over 3 seconds in to red!

In fact at another Redflex town, Grand Terrace, CA. www.highwayrobbery.net had this to say on "late times"
City of Grand Terrace Docs Set # 2
"Late Time" Graphs
The City provided bar graphs of Late Times.
These graphs track violations recorded, not tickets issued.
Where there is a large number of long Late Time violations in a curb lane, it is believed to indicate heavy ticketing on right turns.
(The curb lane will be the lane with the highest lane number.)
This is a sample.

So did he review EVERY SINGLE VIDEO, or just take the vendors "time into red" as "evidience"?????
