Why are there 2 rows of squares painted on the end of White Road?

Here’s the complete question: Why are there two rows of squares painted on the end of White Road? They follow the lane of traffic in one direction for a while, then move to the other lane. Who painted these and why?

And here’s the answer: The painted rows of squares are called speed reduction markings, said Jessi Booker, assistant division traffic engineer with the N.C. Department of Transportation.

“This application was included in the 2009 Manual on Uniform Traffic Control Devices. Speed reduction pavement markings are installed at increasingly shorter intervals to give drivers the perception that their speed is increasing,” Booker said. “These markings were installed on White Road at an unexpected curve to help reduce driver speeds at this location.”

    They should be removed. They cause more of a distraction than help anyone. Stupid idea. I am sure the bureaucrats can point out an expensive study that showed it worked somewhere else. Bureacrats will spend money anytime they can, nickel and dime at a time.

    I’ve never heard of any accidents happening at this curve, maybe the squares will help keep it that way.

    An area that REALLY needs this type of speed reducing thing is the southeast corner of Middle Sound Loop Road where the road suddenly takes a sharp left. I’ve seen cars and SUV on their sides and roof multiple times after losing control at that corner. At the very least, there needs to be more prominent yellow arrow signs indicating the road turns left. Last time I went through that area, there was essentially nothing to show the road had a sharp turn.
