Here's a question about turning:
I thought I heard the city was getting new signals that had turn-left-on-green yield. They would be catching up with the rest of the large cities. I have driven in every major city, from east to west and north to south. I would like to hear from you.
Here's the expert on that one, Smokey.
“An interesting question,” says Oklahoma City traffic engineer Stuart Chai. “There are new standards for permissive (yielding) left turns at signalized intersections that vary depending on roadway conditions
“Generally, if there's a dedicated left turn lane, the current standard is to use a flashing yellow arrow. If the arm on the traffic signal is just long enough to reach to the edge of the separate lane from which left turns are made, it is possible under such circumstances to use a five-section left turn head with an R10-12 sign (the ‘left turn yield on green' followed by an illustration of a green circle (representing a green ‘ball' indication.).
“Here is a link to where you can find this discussed in the Manual on Uniform Traffic Control Devices (MUTCD), 2009 Edition, with Revisions 1 and 2. Note, however, that the left turn yield on flashing arrow sign that Oklahoma City and some other cities are using is not in the manual. The manual is silent on them at this time. This is covered in Section 4D.20 (http://mutcd.fhwa.dot.gov/htm/2009r1r2/part4/part4d.htm).
“There are many instances of traffic signals set up with signals and signs for permissive left turns in Oklahoma City that have been out there for many years. It is not a new practice but it is also not one that can be used everywhere either. It is used with discretion bearing safety in mind.
“Not every intersection lends itself to this form of signal control,” Chai says, “which is why it isn't seen everywhere.”
In another area, here's some good news for those traveling this northern route.
NW 150, between May and Portland (State Highway 74), has had a silt fence erected and possibly some utility line relocation recently. Is this two-lane road going to be widened soon?
Those in the know say the answer is a firm “yes,” Mel.
In December, the project was awarded to those who will do the work.
It will involve widening NW 150 to four lanes between May Avenue and Portland Avenue.
Work on the project began Jan. 21.
Officials say crews currently are relocating a water line near the roadway. You can expect traffic lane shifts to begin in the next few weeks as the roadway portion of the project begins.
By the way ...
Here's some more good news.
Crews should keep lanes in both directions open while the work progresses. Expect the work to continue through the end of the summer.
Enjoy your week and drive safely.
