Traffic signal

[wanderer2575]

Diagonal span wire with two all-direction thru fixtures and a left turn fixture between them.  This used to be a fairly common setup in the metro Detroit area but this is the only one I've seen still existing.

Eastbound US-10 before M-115 west of Farwell, MI.  Good thing there's a green THRU arrow here in case you have any doubts:  /s

I am very, very sure I've never seen anything like this.

Did you look at previous dates?  It's even weirder.

2014 — Keep Right, seems appropriate

2018 — Now let's add the THRU arrow, for whatever reason

I expected it to be a relic from some previous configuration.  But no, it was added.  Cray-cray!

Revisiting this one because I just now noticed that the unnecessary green arrow is preceded by this equally unnecessary matching assembly:

That one doesn't strike me as weird, just because I'm used to seeing that sort of thing in Mexico.

But all of this shows that they really want traffic to not make the mistake of either veering left of the median.  Well, if that's the case, then just put up flashing yellow beacons next to the overhead Keep Right sign—not a green arrow.

Why not just make the yellow traffic delineator cones start earlier instead of at the gore? Seems like a less expensive and less complicated solution.

Avondale, AZ: Buckeye Rd at Avondale Blvd (115 av). This intersection was converted from 5 section PPLT to protected only. Strangely, there appeared to be an interim phase from at least June 2016 to at least November 2016 where the tower was replaced with an FYA assembly, but with the FYA being covered up, leaving just the RYG arrows operating in protected only mode. I'm not sure why they felt the need to cover the FYA when it could just be permanently inactive (as is the case with several installations in Peoria). Eventually it was replaced with a standard three section RYG arrow assembly. All done with no change to the mast arm. A right turn arrow tower was also installed for the southbound approach (from the tracks), with a U turn conflict, as U turns are not prohibited from eastbound. Though actual conflict seems unliekly, as there is no median, thus the demand for U turns would be negligible in theory.

Late edit: I also found this one while google exploring, however I didn't want to make a double post, so I'm editing to add, even though it's completely irrelevant to the above. It's a regular intersection with a diagonal railroad crossing, where one set of left turns does not conflict with the tracks at all. Despite that, the left turns are median separated AND separately gated from the thru lanes. Theoretically, the left turns could proceed without conflicting with the train, however it is still gated, likely to prevent thru traffic from cutting the line thinking they can beat the train. (Dysart / Waddell, Surprize, Az)

In contrast, another diagonal crossing (59/glendale, glendale, AZ) where left turns could theoretically proceed without conflicting with the train, however this crossing is ungated. When the train arrives, the signal goes into four way flash mode, meaning that turns not conflicting with the train are theoretically legal. For some odd reason, there's a few crossings along Grand Av (US-60) in Phoenix that are ungated, despite being very high traffic. One (27/thomas/grand, not pictured) recently had gates installed by 2024.

Double-red left and right turn signals

Double-red left and right turn signals

Wow... it looks like a temporary setup but still... can't say I've ever seen that for all turn signals

[jakeroot]

Double-red left and right turn signals

It's also not compliant, as there aren't two primary heads for one of the turns. There is a near-side left turn signal, but in that position, it would only be supplemental to the primary heads.

Tangentially: that is at the site where the new training facility for the Carolina Panthers was being constructed. new exit on 77, new local roads, etc. But then the city of Rock Hill and the team's owner had a disagreement over funding, so the half finished building was torn down. Absolute waste of tax money, and a huge local controversy. The Panther's owner is basically a local villain now.

Double-red left and right turn signals

Looks like the other approach has a right green arrow. I assume that's for when they build the other connecting road and it goes from a T-intersection to a four-way?

[kphoger]

Uggh.  This crosswalk signal now displays both a steady green ball and a flashing yellow ball at the same time—on all signal heads, in both directions.

That violates the MUTCD, right?

Sounds like something in the controller went kaput and the conflict monitor unsuccessfully tried to throw it into flash mode as a result.

You don't suppose the city just decided drivers need to be more careful, so they just added flashing lights?

Second a faulty controller. We had a tropical storm a couple years ago and one intersection had both regular mode and flash operating at the same time.

OK.  I just reported it to the city, and asked them to let me know if it's not a city installation.  Thanks.

That's so weird. Is there any video of that?

Tacky.


Signals aren't going up, but have been removed as part of Lakeland,  FL plan to eliminate some intersections traffic lights as no longer warranted.

Just aren't urgent about removing the poles and mast arms.

Weird that they wouldn't just leave them in place as a 4-way red flasher, since there are stop signs there anyway.  That would allow them to reactivate them in the future if necessary.

They were left as four way flashers for a long period after the deactivation.   They should have just added one section heads as permanent flashers.

About 20-some years ago, they did the same thing in downtown Youngstown, OH, while in Erie Pa, they just zipped up the deactivated signals in "body bags" and called it a day.

Glendale, AZ has a few lights that've operated in permanent flash mode since at least 2008. They're both near a stadium, so it's possible that they actually operate during events, but I havent been able to confirm that.
93/Hanna Ln: https://maps.app.goo.gl/VMB9f6mGztSn2cQA6
Upon satellite inspection, the light seems to have been built in 2004, and an auxiliary parking lot constructed around 2009, though its been gated off in every GSV capture. Most recently it got replaced with an apartment complex, but the light still operates in flash mode.

93/Entertainment Blvd: https://maps.app.goo.gl/WgADhJfPHLUZp6ni8, also constructed in 2004.

Also in the area is a "Right on red arrow after stop", which is interesting because a simple red circle would suffice, but I guess they wanted to emphasize against the thru movement, as the road then a private farm road.

Costs more money to send a crew out to change signal heads and replace them with single flashers, than it would to just put the intersection into four way flash until the bulbs burn out. Though eventually they would need to remove the signal heads, but by then it's someone elses budget problem.

The current scene on US 1 in Maryland where 2 new side by side signals are being put up, resulting in 4 layers of signals:

Old signals are now gone.

Over a month ago, I visited Madison, Wisconsin, to film some of the traffic signals there. Among them were ULTRA RARE 3M pedestrian signals! There were four intersection with them, and two of those featured a separate countdown section.

Nice!!!

SN: seems like Madison doesn't give you a lot of time to cross the street.

[riiga]

Very cool! Green for walk (when on a dedicated signal) is quite uncommon in the US, is it not? As well as that countdown time with blinking hand?
