Last week, Dallas officials reviewed the numbers and decided that a quarter of the cameras they had installed to catch motorists running red lights were too effective. So they shut them down.

They are not alone. Faced with data showing that drivers pay attention to cameras at intersections — resulting in fewer ticketable violations and ever-shrinking revenue from fines — municipalities across the country are reconsidering red light cameras, which often work too well.

At the heart of the discussions taking place in city councils and county commissions is tension between the twin benefits that were touted when local governments began installing cameras about a decade and a half ago. Officials were promised that the cameras — which take snapshots of busy intersections, capturing the license plates of any cars that are running the light — would simultaneously save lives and generate millions of dollars in extra fines.

The first half of that equation is arguably true: A federal study found a small but measurable reduction in injuries nationwide in accidents at intersections monitored by cameras, though there was an increase in some kinds of collisions.

It is the second half of the equation that may be beginning to collapse. As drivers learn where the cameras are, they are more careful. Fewer of them run red lights. Local governments collect fewer fines.

Fewer violations = less revenue
Sometimes, as in Dallas, cameras generate so little revenue that they can’t even pay for themselves.

Citywide statistics obtained by NBC affiliate KXAS-TV found that red light cameras do reduce accidents. That is a good thing.

But they do it by reducing red light violations, by as much as 29 percent from month to month at particularly busy Dallas intersections. On the face of it, that, too, is a good thing — but not, necessarily, if you rely on traffic fines to make up a healthy chunk of your budget.

Dallas lawmakers originally estimated gross revenue of $15 million from their 62 cameras this fiscal year, which ends June 30. But City Manager Mary Suhm estimated last week that the city would fall short by more than $4 million.

So last week, the city turned off about a quarter of the least profitable cameras, saying it couldn’t justify the cost of running them.

Safety benefits questioned
Dallas was just following the lead of several other cities that have shut down red light cameras.

City officials in Charlotte and Fayetteville, N.C., recently turned off all of their red light cameras, concluding that a state law diverting much of the revenue they generate in fines to schools meant their general funds were actually losing money, NBC affiliate WNCN of Raleigh reported.

In Bolingbrook, Ill., meanwhile, officials ended their red light camera program after statistics showed a 40 percent drop in ticketable offenses.

Nor is money the only reason cameras have been removed. In Lubbock, Texas, the City Council shut down all its cameras last month, citing a report that showed statistically significant increases in rear-end collisions at intersections, including those with cameras.

Rear-end collisions, in fact, have been cited in numerous reports and lawsuits questioning the benefits of red light cameras. Opponents claim that the cameras actually create more hazardous conditions.

“When people know there’s a red light camera, they change their driving behavior, and they slam on their brakes trying to avoid a ticket,” said Tom McCarey, an activist for the National Motorists Association. The association, which is based in Waunakee, Wis., calls itself a 6,000-member group “dedicated to representing and protecting the rights and interests of North American motorists.”
