Salem -- Smile-- you're on candid [red light] camera

Statesman Journal--

Police Chief Gary Moore announced Wednesday that Salem police have chosen Redflex Traffic Systems, a Scottsdale Arizona company, to place red light cameras at Salem's busiest and most dangerous intersections.

" The Redflex cameras would take still pictures of rear license plates and the faces of oncoming drivers, and 12 seconds of video per incident in which a motorist is alleged to have run a red light. This evidence would allow police to determine whether a violation has taken place and identify the driver. "

Redflex would install and maintain all video equipment at its own costs, process and Mail citations, and could assist in collections. The company in return would receive a portion of each traffic fine.
Under the proposed plan, as many as eight Salem intersections would get red light cameras.

" Although the company has been chosen, a public hearing will be held within the next couple of months to get residents’ comments on the company’s proposal, assistant city manager Linda Norris said. The City Council has the final say on whether to implement the cameras. "

the claim about red light cameras, is that they reduce accidents by photographing the car & driver in the act of running a red light.
In fact, according to a June 2, 2004 report from Virginia Secretary of transportation Wellington W. Clement, suggest that red light cameras actually increase the risk of traffic accidents.[source]
Additional concerns for establishing adequate yellow interval for traffic signals, not using the program to raise revenue [of course they would never do that], and avoiding software or hardware errors in the operation of the system.
Conclusion of the study was the number of crashes attributed to red light running has decreased, although the number of rear end crashes has increased.
