Same TTI Researcher DESCREDITED in 2008 TX DOT Report, does another RLC "report" claims they "work".

(BAN THE CAMS WILL POST MORE INFOR ON THE FLAWS OF THIS REPORT AS THEY BECOME KNOWN)

Add this one to the list of desperate reports by the scamera side claiming rlc "work".

Here we have a TTI study that claims they work.  http://tti.tamu.edu/2011/08/01/safety-benefits-of-red-light-cameras/#comment-263 

Troy Walden July 2011 http://tti.tamu.edu/wp/wp-content/uploads/2011/07/Evaluation_of_Photographic_Traffic_Signal_Enforcement_Systems_in_Texas.pdf

WHAT IS REALLLY INTERESTING IS THAT Troy Walden who did this "report" is the SAME RESEARCHER WHO DID THAT TTI REPORT in 2008 Claiming RLC "work".

HIS REPORT WAS UNDERMINDED BY THE HOUSTON RICE UNIVERISITY RLC REPORT!

Here are a few "highlights" of what was PULLED THEN!

The Rice-TTI dataset also throws doubt on the conclusions of the TxDOT-TTI study (WALDEN). Increases in Houston collisions documented by Rice-TTI mysteriously became decreases in collisions in the TxDOT-TTI report (WALDEN) , as follows:

•Monroe at Gulf Freeway East Service Road: a 913% increase became a 41.7% decrease
•Hollister at Northwest Freeway: a 747% increase became a 60.5% decrease
•FM1960 West at Tomball Parkway: a 307% increase became a 44% decrease
•Richmond at Dunvale: a 103% increase became no change
•South Sam Houston Freeway at Telephone Road: a 164% increase became a 19.3% decrease
•East Freeway North Service Road at Normandy: a 52% increase became a 25% decrease
•North Freeway West Service Road at West Rankin Road: a 18% increase became a 32.7% decrease

In other cases, decreases became more pronounced and increases lessened. To cite just one example, a 217 percent increase in accidents in the red light camera approach of Scott Street at South Loop East North Service Road in the Rice-TTI report became a 50.1 increase in the TxDOT-TTI report. In general, far fewer collisions were reflected in the data used in the TxDOT-TTI report. Since Houston's results comprised more than one-half of the statewide results, it is unclear how TxDOT and TTI could have concluded a statewide reduction in accidents without data manipulation in at least one of the TTI reports.
