Photo Enforcement Vans for Speeding
From Suburban Journals – News:
A very good article on the technology and process of using photo enforcement vans to catch drivers speeding. I believe right now, Illinois is limiting the use of these vans to construction zones. Here are some interesting details:
In two hours one van recorded more than 66 vehicles exceeding the speed limit, at $375 a ticket, that works out to $25k an hour!
A typical photo enforcement van uses two cameras and a radar speed detector to monitor passing vehicles. For those vehicles exceeding the set speed limit, the van snaps four photos as the vehicle travels through the photo zone. Drivers usually receive a speeding ticket in the mail a few weeks later.
Each photo is marked showing the speed of the vehicle, the time of day, location, posted speed limit and other essential details.
The vans currently use 2.1-megapixel cameras, enough to print out a high-quality 5-by-7 photo. The next generation of photo van cameras will take a 7-megapixel image, providing even more detailed pictures of speeding drivers.
