Traffic light question answered

A long time ago, I asked my first in a small series of vexing questions about Waxhaw.
I've always considered this a vexing Waxhaw question if there ever was one, but can anyone explain why there's no left turning light to turn onto Broome Street from 75?
Well, I finally got an answer and it's simply this: because NC DOT says we don't need one.

As I mentioned in an earlier post, NC DOT recently did a count to determine if the need for a dedicated left turn light for eastbound traffic was needed. I ended my post with what essentially was a gloomy predictions of the results, which turned out to pretty accurate.

Sean Epperson of NC DOT emailed to say that after performing the traffic count on September 22, they have concluded that a dedicated left turning light for eastbound traffic into the 16/75 intersection is not warranted. Per their calculations, the time that the eastbound traffic would save would get shoved onto north and southbound traffic, thus making the point moot as far as NC DOT is concerned.

One positive change for eastbound traffic is that the 6' x 6' inductive loop will be replaced with a 6' x 25' loop. (For more information on how this works, see here.) During the count, some instances of eastbound traffic through the intersection were not detected by the already existing smaller 6' x 6' loop, so installing a larger 6' x 25' loop should resolve that issue. This work has not yet been scheduled.

While monitoring traffic that day, Sean also made some changes to the timing of the traffic light in an effort to further improve the efficiency of the signal. So hopefully the combination of these changes will minimize delays for eastbound traffic through the intersection. We'll have to wait and see.
