So a driver may observe the intersection in Condition A and might think that is also the mode of operation in Condition B or Condition C, when they are actually turning.

I observed my favorite FYA and noticed 3 different patterns.
Surprise! Not all FYAs are equal.
And not all FYA intersections are the same.

ACHD recently sent a notice that heavy fog may interfere with the sensors. Okay. And they are testing spending THOUSANDS $$$ more to use radar sensors..
At what point of additional cost does ‘computerized traffic control’ become nonsense?

It would be better if ACHD spent their “computerized” efforts timing our lights (adjusting more frequently as needed) to minimize stopped traffic on primary routes (helps our air quality for one).

So for now, do I get a green arrow, or not, in foggy morning traffic if the sensor doesn’t detect my vehicle?
By the way, it’s FOGGY and I can’t see oncoming traffic or pedestrians very well.
“Gun it and make that flashing light!”

Now I would like to see right turn only lanes in multi-lane intersections. Nothing more aggravating than a driver having lane options at a red light selecting the right lane to await green while cars behind want to turn right.

I think the answer lies in education of drivers. Be it public service spots on tv, a short video of traffic law changes when you renew your license. It ain’t that complicated but people need to know how to react at these things.

It makes me nutty at how some drivers react to something so simple.

Problem #1 is ACHD does not measure success or failure by the safety of our roads. Examples are everywhere but mostly in the form of stupidly high speed limits. High collision speeds convert mistakes into deaths.

(Eastie, that’s twice we agree this year. You’ve come a long way!)

Note: The ACHD press release stated, “If [IF] the new signals perform as expected, increasing safety while reducing delay,”

IF???????
How about WTH? IF?!

Based on their rationale, the engineers already did determine it IS safer when they started changing the lights- back in 2009 and 2010.
IF?
That’s like saying, “So IF no one dies from smoking in the first 2 years, we’ll keep selling them.”
Okay.

But then,,,, the enlighted (pun intended) people in Oregon came to a different conclusion a few years ago.

“Oregon transportation researchers have found that the signals pose serious safety risks to pedestrians.”
http://www.oregonlive.com/commuting/index.ssf/2013/04/oregon_traffic_study_widesprea.html

To pedestrians. Too bad! No one cares about pedestrians…

Well if a driver moves into the intersection thinking they found ‘a hole’in oncoming traffic and then quickly realize a pedestrian is in the crosswalk blocking the left turn- the turning vehicle will come to a stop— RIGHT in front of the oncoming traffic because it was only a small ‘hole’ in traffic. Collision!
Speed limits where these are used???

As for our old drivers, a study in Illinois agreed “It is also recommended that when FYAs [flashing yellow arrows] are implemented, efforts be made to educate not only the driving public at large, but OLDER drivers specifically to further improve safety for drivers making left turns at signalized intersections.”

The Illinois study showed no safety improvement for older drivers… why is that?
If blinking yellow arrows (FYA)fit with the “driving fundamentals that have been around as long as cars” as Concerned Neighbor implies, then old people should have a better response to the new signals- they have the most ‘experience’ with the driving fundamentals.

Remember, we have been using these for only a few years with any kind of density. Final Results?

IF….
It doesn’t take a PhD to recognize a dangerous situation.

“Yellow lights, as symbols, have never meant: “You can go but you don’t have the right of way”.”

“Before the new lights went up at 121 and 56, police worked about an accident a month there. Now that the flashing yellow arrows are in operation, accidents have quadrupled — averaging four accidents a month.”

“The new flashing yellow arrows are still causing confusion and leading to accidents…”

It has scrapped all its traffic lights and road signs in a radical experiment designed to make the streets safer. Yesterday, the local council said the scheme was a complete success…”
