The Brunswick Forest traffic light in Leland is on a superstreet design that manages traffic more efficiently than traditional full-movement signals, said James Dunlop, congestion management engineer for the N.C. Department of Transportation.
What the superstreet design does is time the lights to optimize traffic flow.
“Regarding the specific signal timing issues on U.S. 17 near Brunswick Forest, the superstreet design manages traffic more efficiently and safely than traditional full-movement signals. Even with turning right and then waiting for the U-turn signal, the movement towards the south (in this case) is usually quicker with the superstreet than waiting for the signal to cycle around to serve the side street turns. Drivers may perceive that it’s taking longer, though, and get frustrated with the signal timing. To properly coordinate the signals (mainly for U.S. 17 traffic) the green for the main street must be held during the signal cycle, so that the signals can turn in sequence. That’s why the red may seem to hold ‘with no traffic out there,’ but the flip side of that would be the red coming up on the main street more often, stopping the higher volume of traffic. So often, the answer to ‘the signal timing isn’t working’ is that it really is in an optimum pattern. However, that means that certain traffic has to be held longer than some drivers would like.”
