Watch out and maybe slow down a little.

Get ready for a smarter speed camera. 

Corridor averaging uses multiple Automatic License Plate Recognition, or ALPR, cameras posted at multiple points along the road. Your license plate is captured and recorded again and again as you drive past more cameras, each taking a picture with a time stamp. With some simple distance and time math, an average speed is computed, and possibly a ticket sent to your home address.

These cameras have already been in use in parts of the United Kingdom since 2004, and testing is being conducted stateside, with Montgomery County, Maryland, introducing them in 2012. The county changes the location of the cameras regularly and posts that information online.

While many people dislike the surveillance aspect of these plate-recognizing, speed-monitoring cameras, the corridor averaging system has 30 percent decrease in deaths and serious injuries, according to a study done by the Insurance Institute for Highway Safety.
