Optical Speed Bumps Tested In Oregon To Slow Drivers Down
Oregon engineers are testing optical speed bars to slow traffic down. It's basically an optical illusion used to get speeders to step on their brakes and slow down. The speed bars are being tested at the intersection of Oregon 211 and Dubarko Rd. Studies have shown to decrease the average speed at problem intersections by up to 5 mph depending on the location. It's a low cost alternative to getting drivers to slow down. The speed bars make a driver think they are going faster than they actually are. Each bar is a foot wide and 18 inches long, they are spaced at gradually decreasing intervals to create the illusion.
