Are red light cameras saving lives? The data says yes.
In Nassau County, accidents at intersections with red-light cameras were down 26 percent in 2016, compared with the number of crashes in the 12-month period before the cameras were installed at each intersection. Crashes with injuries were down 39 percent, head-on collisions declined 84 percent, side-impact collisions dipped 1 percent and rear-end accidents were down 34 percent.
Both Nassau county and Suffolk county are authorized to install cameras at 100 intersections. Nassau has them at 86 intersections, with the number increasing gradually since 2010 and the number of cameras at some intersections increasing, too.
Accidents for all of Nassau have declined, too, but not as much as at the red-light camera intersections, where 5 percent of the county’s collisions occur. According to preliminary figures, total accidents in Nassau County in 2017 were down 12 percent compared with 2010, while auto fatalities declined 20 percent and accidents with injuries declined 11 percent.
County officials say they believe the annual total of miles driven in Nassau has increased. And to show cameras do work to improve habits, the officials point to data showing infractions generally decline at an intersection a few years after cameras are installed.
Mixed results in Suffolk: In Suffolk County, the news is more mixed because the data is compiled differently.
The county began installing cameras in 2010, and had nearly maxed out its allotment by 2014. In 2016, total collisions at red-light intersections in the county were 1.5 percent higher, compared with the annual average for the three years before the program began, 2007-09. However, accidents with injuries declined 1.5 percent. Dangerous right-angle collisions were down 23 percent, but rear-end collisions were 35 percent higher. That’s a daunting number, but the data suggest, and county officials believe, that new driver distractions like smartphones are causing the increase in rear-end collisions, not late braking to avoid red-light camera tickets.
Suffolk’s rear-end collisions on all roads are up 23 percent compared with 2009, and up a nearly identical 22 percent at red-light-camera intersections in that span.
Related considerations: Many drivers don’t focus on driving as they talk on and play with phones and attend to navigation systems and other gadgets. There are critics that claim yellow-light times were reduced to induce violations, however, officials in both counties categorically deny it has ever happened.
