WAKE COUNTY, N.C. (WTVD) -- The NC Department of Transportation (NCDOT) is leading the effort in creating the nation's first design that aims to improve traffic flow at busy intersections.
NCDOT says the dynamic left-turn intersection will vary the number of available left-turn lanes using dynamic signal phasing to reduce travel delays. The design will use a pair of LED-powered overhead signals that activate or deactivate the rightmost left-turn lane, depending on the time of day and traffic conditions.
