number rarely lie , and the number bring on by the 2011 Insurance Institute for Highway Safety ( IIHS ) say cherry - brightness cameras do indeed save lifetime .
Red - wakeful camerastake photos of people running violent lights . The survey showed intersections with cerise - light cameras see a drop cloth in the bit of trespass . Consequently , the number of accident goes down , and as the number of accident strike down , the number of fatalities drops as well .
While the logic is square - forward – fewer violations , fewer chance event , and fewer deaths – detractors say the manipulation of the television camera can move away from the original safety intent and tincture into a revenue - yield tactic for the 500 - plus city across the country now using them . Indeed , one study from the University of Southern Florida College of Public Health claims the television camera can , under specific circumstances , increase the number of accident and potential related to fatalities .
Yet since the first crimson - light camera were installed more than a decennary ago they ’ve helped trim down the numeral of accidents at the carrefour where they ’re used as well as other areas of large urban center . While their ultimate role and presence can be fence , the results of the IIHS study show they are effective .

How many lives saved?
mostly speaking , red - light camerasare part of a connect system represent of three main components : the camera , a trigger and the stop lights themselves .
Atrigger , usually an induction coil , is embedded in the roadway at the overlap lay off line . When the signal is red , or even sometimes yellow depend on the residential area , electricity is run through the curl . This creates amagnetic fieldthat reacts with a car ’s metal deal . change in the field , such as run a red visible light while it ’s on , head trip a switch . This switch , in turn , triggers two of four camera generally mounted at each corner of the intersection . The camera fool photos of the violator ’s licence collection plate and/or the driver ’s font . The photograph is swear out and a ticket is sent to the traffic scofflaw .
Recent advances in technology are doing away with induction trigger and integrating more engineering into the system . Some cameras now keep a never-ending video surveillance of an overlap and bed when someone run a red light . tot to this is the ability to calculate the vehicle ’s speed giving the dominance the opportunity to represent on , and ticket , two possible encroachment .
According the IIHS subject area , red - light camera saved the lives of more than 150 mass over the five - year period of the subject , which rivet in 13 major city in the United States . The study sum up that if the 99 turgid city in the country had installed the cameras the number of life saved would have jump to more than 800 .
In more specific term , the study found the cameras reduced the rate of fateful ruby - light run crashes by 24 per centum , and had a confirmative effect of reducing all fatal crashes at signalized carrefour by 17 pct .
Some subject area have show exceptions to the IIHS results . As mentioned on the first page of this article , a account by the University of Southern Florida College of Public Health , and publish in the 2008 Florida Public Health Review , said red - light cameras could get more stroke than they prevent . Though drawing from the termination of a 2002 IIHS crimson - light photographic camera survey , the authors concluded that the state ’s older drivers often could not respond quickly enough to halt at lights and this reduced reaction time , coupled with a red - visible radiation cameras split up - minute amphetamine , could result in more crash as old driver ’s attempt to make degenerate stops , as well as a higher cost to the public in the terms of property going , tickets and higherinsurancerates .
The USF study instead suggested reengineering crossing , increasing the time yellow light are on , and other methods for reducing signalized intersection crash . They also questioned the results based on the IIHS ’s close affiliation to the auto policy industry .
letter regarding the USF study , and the 2002 IIHS written report , both reenforcement and condemn both reports , their sources , methods , analysis and demonstration .
The idea that red - light cameras save life is not in interrogation . No matter how many way the numbers are looked at or translate – the fact is that some people are walk and driving the streets today that may not have otherwise thanks to their mien .
