SYOSSET - A study by the Insurance Institute for Highway Safety has found that cities that shut off red-light cameras had a 30 percent increase in fatal crashes from people running red lights.
The researchers looked at red-light camera programs in 79 large U.S. cities and concluded "there are hundreds of people walking around who wouldn't be here if not for red-light cameras."
Dawn Nappi, whose daughter Angelica was killed in a traffic accident, says one large study can't tell you all you need to know.
She had supported red-light cameras for years until other recent data released by Suffolk County found that rear-end accidents increased at some intersections with red-light cameras.
"Is it about saving lives or is it about raising money?" asked Nappi.
Suffolk Legislator Tom Cilmi wants to temporarily suspend Suffolk's red-light camera program until it's all figured out. He also says he would like to increase the length of time that all lights at an intersection stay red.
"Sometimes there's traffic rushing through to get through before the light turns red," says Cilmi.
Robert Sinclair, of AAA, says all the data could be skewed because there are more drivers on the roads.
"We are seeing a general upward trend in accidents and deaths because gasoline being so cheap and so many more people driving," says Sinclair.
