?? about red light cameras in Phoenix
You know Duker that has a definite ring of truth to it. As I stated in a previous post I have a hard time effectively stopping or clearing the intersection on changes now in heavy vehicles. This has never been a problem till just recently. You might as well quit wasting you're time on bbcrud. He's not giving your facts due consideration-if he were he'd have come around by now.

I live near one of the most dangerous intersections in the Phoenix area. The problem there has not been the length of yellow. (The problem has been identified in other areas though)
Making longer yellows is the answer for people that would try to stop if they could do so safely. This, however, is not a flat, single-dimensional, issue.

Yellow lights intervals, the panacea for all red light running issues.
Duker's Washington info is flawed and that's the only current thing he's come up with.
scholarbb - What facts did I not give due consideration to? Point them out then tell me what's wrong with my rebuttal to them? Please? Show me where every installed RLC is a bad idea and adjusting all yellow light intervals in the best remedy to innocent people being injured or dying at the hands of a careless driver.
By the numbers
● 35 mph: common speed limit for city streets.
● 51 feet per second: distance a vehicle can travel at 35 mph.
● 1.5 seconds: time it takes for quicker drivers to react (and hit the brakes).
● 77 feet: distance a vehicle traveling at 35 mph would travel before the driver hits the brakes.
● 3.7 seconds: total time it takes for vehicles traveling at 35 mph to stop (including a driver's reaction time), under ideal conditions.
● 189 feet: distance it takes for vehicles traveling at 35 mph to stop, under ideal conditions.

Maybe add a 50% safety buffer to this formula to allow for slower reaction times.
(Then install RLCs to catch the buttheads that still run lights!)

Here's how cameras can be used properly.

5 seconds is more than long enough for anyone who is actually paying attention to what they're doing (which should be driving) to come to a full, safe stop. Yellow means slow down, not try to race the light. Some people seem to have forgotten that.
Also, anyone who pays attention knows that the little "DON'T WALK" signs blink 13 times at major intersections before going solid. At the moment they go solid, the light changes from green to yellow. So not only do you have the 5 seconds of yellow, but you have the approximately 10 seconds of flashing "DON'T WALK" to warn you as well.
Ya know what's the funniest about this? All intersections in Phoenix with RLC's have big signs well before the intersection pointing out that the intersection has an RLC. So if people get popped for running a red light, it's their own fault for being stupid.
Want to get rid of RLCs? Stop running red lights. All of a sudden, those cameras become useless.

Since you don't live here, and it doesn't appear you've ever been here, you can't fully grasp just how easy a RLC ticket is to avoid and how well the system has been designed. The RLC tickets in Phoenix are impossible to beat in court if you were driving your own car. And you'd realize that anyone who is still running red lights at those intersections is absolutely retarded.
Back to the original question (I didn't see anyone point this out)

Even harder to beat when you been dead 5 years
Are your RLCs' any different than the rest of the countries? Lets assume they are.

City of Phoenix Aggregate Conclusions
The effects of red light cameras are assessed at 10 intersections in Phoenix equipped with
RLCs. The final results are based on the comparison group method results, which is the best
method available for the Phoenix data. The results for target approaches are:
• Angle crashes decreased by 42%
• Left-turn crashes decreased by 10%
• Rear-end crashes increased by 51%
• The estimated net crash benefit is $4,504/year for the 10 target approaches
The estimated impacts on all approaches are less than those on target approaches. The results
for all approaches (including both RLC and non-RLC approaches at RLC intersections) are:
• Angle crashes decreased by 14%
• Left-turn crashes decreased by 1%
• Rear-end crashes increased by 20%
• The estimated net crash benefit is - $324,836/year (i.e., negative, meaning more costs than benefits) for the 10 intersection approachesSpillover effects do not appear to be present. The net crash benefit on the targeted approaches
is relatively small because the RLCs in Phoenix contribute more to reducing angle and leftturn PDO crashes than to reducing fatalities and injuries associated with these crashes. In
addition, a few intersections dis-benefited significantly from the installation of RLCs and
these intersections heavily weighted the “average” benefit for the 10 RLC intersections.
Ok lets get back on topic

You are absolutely correct. He's going to end up paying more in the long run. And statue of limitations doesn't apply here. Did he receive a ticket in the mail? Yes? Then he's been cited/charged well within any statue of limitation that may actually exist.

2 does the red light camera have a picture of the drivers face? Unobstructed? If not the ticket will be thrown out.

I put up the stage for country thunder 3 years in a row and did the same thing up here for twin lakes
Oh and its pretty easy to avoid an RLC. Good driving skillz and a license plate cover that obliterates its view from angles

From the above results, the effects of RLCs on safety in Scottsdale are summarized as
follows:
1) Similar to previous studies and results for Phoenix, angle and left-turn crashes are
reduced and rear-end crashes increase.
2) The magnitudes of reduction or increase for each crash type on target approaches are
slightly greater than those on all approaches, indicating the spillover effects are present,
but relatively smaller than the effect on target approaches.
3) The crash net benefit is relatively large because the RLCs in Scottsdale contribute more
to reducing the costs of fatality and injury crashes associated with angle and left-turn
crashes than to increasing the costs associated with PDO rear end crashes.

The RLCs in Phoenix and Scottsdale are effective on target approaches, but the
magnitude of effectiveness in Scottsdale appears to be greater than in Phoenix. However,
they are statistically similar—that is, the statistical variability surrounding the estimated
benefits for the two cities is large. Crash severity is affected by RLCs, and the extent to
which severity is reduced for angle and left-turn crashes determines whether the RLC
program yields a net positive benefit. Increases in rear-end crashes as a result of RLCs
tend to yield increases in property damage only crashes, and thus do not significantly
impact the economic analysis.

I dont know the laws in arizona But there are lots of resources on the net.
On a personal note Yes ive been to arizona, no i wouldnt want to move there.
I put up the stage for country thunder 3 years in a row and did the same thing up here for twin lakes
Oh and its pretty easy to avoid an RLC. Good driving skillz and a license plate cover that obliterates its view from angles

In short: Your narrowsightedness and fear of the government is all too apparent. If you can't see the huge benefits RLCs have over the disadvantages, then you should just give up now.

But the bad news for Retting doesn't end there. Curious about some of Retting's crash conclusions, the National Motorists Association's Jim Kadison secured accident data for the red-light-camera intersections Retting used in his latest Oxnard report. Retting had estimated that the use of red-light cameras had resulted in a tiny 3 percent increase in rear-enders at all signalized intersections. But after expanding the definition of an intersection to include 100 feet into the approaches, where rear-end accidents would logically occur, Kadison found that during the time of Retting's study, rear-end crashes at red-light camera intersections increased from 18 (before installation) to 156, for a total rear-end accident increase of 767 percent.
When I called Retting to needle him about the inconsistencies in his studies, he grew peevish. "The studies speak for themselves. . . . You can look at it any way you like, I have nothing to apologize for." Somehow, he seemed to discount the criticism, since I was not at his "professional level" and had no grasp of logistic regression models. "If you don't have the ability to appreciate the logistic regression model," he condescended, "it's really a waste of time." Perhaps so. But I can appreciate Greg Mauz's assessment of Retting's reports: "Swiss cheese doesn't have as many holes."
Retting, to be sure, isn't the only fuzzy mathematician in the automated enforcement arena. Police departments, who are coached by their contractors to preach the safety gospel every chance they get, tend to advertise success by displaying the declines in violations, while failing to produce numbers that prove cameras reduce accidents. When I called the D.C. police for accident statistics, spokesman Kevin Morison said, "We don't have comprehensive data on accidents by intersection at this point." He then referred me to Lockheed Martin IMS, whose spokesman, Mark Maddox, proceeded to refer me back to the D.C. police. When I told him the police had referred me to him, he sniffed, "Obviously the numbers speak for themselves." Maybe they would, if we knew what they were, I said. "We're not in the accident monitoring business," Maddox explained. "We don't have that ability, no." Odd that a company whose raison d'etre is supposedly reducing accidents has no way of knowing if accidents are being reduced.
