I just sat at the Wake Forest Road & Six Forks Road intersection for a whole cycle and I'd say about 50%+ of the drivers in the dual left turn lanes didn't pay any attention to the guide lines and sometimes were in the other lane's turning path......

You can't fix stupid. Regardless, the point being that the number of turn lanes equals the number of thru lanes.

I wish they would stop putting them on Erwin Rd in Durham!

Unfortunately, I predict Raleigh won't ever embrace this huge aesthetic improvement to intersections as a priority.

They all replied how expensive it is, so I say let private citizens sponsor an upgrade to the intersection of their choice.
I believe Durham has a mix of Wire fixtures (most of the signals on 15-501) and Pole mast fixtures (most of the fixtures around Southpoint Mall). From an aesthetic standpoint, I like black pole mast fixtures and streetlights better. I would prefer roundabouts to signalized intersections where possible, but as evidenced by the one on Hillsborough Street in Raleigh, it wouldn't work out.

I think the problem with the Hillsborough traffic circle is that it's too small and the topography screws up the approach from Oberlin. Drivers on Hillsborough can bomb through very quickly, whereas from Oberlin, you have to go more slowly. If the circle were bigger and drivers approached at the same (reasonable) speed, I think it would work better.

They are also installing roundabouts at Brooks Avenue, Dixie Trail, and Rosemary/Shepherd Streets.

We'll see how that goes.

To a degree....I see the efficiency argument for the damned yellow blinking arrows for left turns. I do think they still throw people off when the light for the thru-traffic is red but but the arrow is blinking yellow....turning left at a red light has always been illegal so I think that still throws a little people off.

What angers me to no end is when there is a TON of oncoming traffic, the left turn lane is backed up.....and you go the whole cycle with NO left turn right of way (green left-arrow)...just the damn yellow blinker. People turning left often have to wait 2 or 3 cycles before maybe 1 or 2 cars can actually turn left safely...often when the left turn lane is 10+ cars deep. Give us a green arrow..even if it's just for 10-15 seconds!

I see this regularly in Chapel Hill turning off 15-501 to Culbreth.

Depends what the left turn and oncoming thru traffic movements are at that intersection - usually there are reasons why there isn't a protected left for that movement. I live near an intersection where everybody wants a protected left for this one side street but apparently the left turning volumes don't meet warrants for putting in a protected left.

Yeah, those are useless. Even more so when the blinking yellow is the last light on the signal (no green whatsoever ).

Here's a scenario where a blinking yellow would be a GREAT idea, and it's the exact opposite you describe.

If, say, there's an intersection where you want to make a left turn/U-turn, and there is no traffic coming opposite you for a good 30 seconds at minimum... but you can't turn left because all you get is a solid red arrow.

The intersection at Louisburg and Spring Forest/Kyle is what I describe. To make matters worse, that light is programmed for the shortest left-turn phase I've found in the entire county.

The flashing yellow arrow is a pretty new thing so they've probably only implemented it at signals where changes needed to be made anyways etc....

The flashing yellow is simply a new display for solid green ball, left turns permitted but yield to oncoming traffic.

I think they decided that people are too stupid to discern the difference between solid green ball left turns from protected green arrow left turns.

Almost all of Atlanta's intersections allow lefts on solid green ball with yield.

NC historically didn't allow many lefts outside of the protected phase.

So the flashing yellow is an improvement.
