A study released by the state shows mixed results at a New Brunswick intersection where a camera has been in place for over a year.

According to the New Jersey Department of Transportation, New Brunswick has one red light camera installed, located at the intersection of Easton Avenue and Park Boulevard. This intersection is the turn to access the emergency room of Saint Peter's University Hospital from Easton Avenue.

According to the report, in the year prior to the installation of the cameras, a total of seven accidents - two right angle crashes and five same direction crashes -  were reported at the intersection, at a total cost of $51,800.

In the year following the installation, same direction crashes decreased, dropping from five to one, and right angle crashes increased from two to three.

Accident costs following the camera installation totaled $86,900, according to the report.

By comparison, at the intersection of Easton Avenue and Albany Street, where a camera is not present, four right angle crashes were recorded in the year prior to the installation of the red light camera program, and three were noted in the year following.

At that same intersection, 11 same direction crashes were noted in the year prior, and eight in the year following.

Cpt. J.T. Miller of New Brunswick Police Department said the camera program is too limited in New Brunswick to make any decisions on how effective it has been.

"In the report for New Brunswick (you're) talking a difference of one accident," he said. "That's a 33 percent increase (but only) one accident."

The state report suggests the same for the program statewide, and recommends continued use and monitoring of the cameras.

New Brunswick has done research of other intersections to see where cameras could possibly be used, Miller said. He declined to disclose where those other intersections in New Brunswick are.

According to a report by NJ.com, the study shows that an overall increase in accidents was observed at two dozen intersections throughout New Jersey where the cameras are located.

The total number of crashes statewide increased from 577 the year before the cameras went up to 582 the year after, according to NJ.com.

That small increase brought with it a $1.2 million increase in "crash severity cost" which looks at multiple bills resulting from crashes, including property damage and emergency response, according to the news agency.

The 24 intersections observed had at least one year of data as of Dec. 31, 2011. Since that time, the number of intersections in New Jersey with red light cameras has risen to 85, according to NJ.com.
