Traffic signal

[hotdogPi]

What is going on here? Loring St. at Salem St. in Lawrence MA.

2020 GSV shows flashing yellow, looking in-person a few months ago shows flashing green (Massachusetts old standard so not actually a malfunction), but now both green and yellow are flashing, and not at the same rate. To the left of the camera is a non-malfunctioning flasher, but I can't remember if it's green or yellow.

You'll have to click to open Flickr if you want to see the video play.

Could it be similar to this signal that I encountered in Randolph in August 2024? In my case, it reset itself once a train tripped preemption, not sure if activating the pedestrian phase would temporarily fix it. Might be an MMU malfunction, or something else entirely that is malfunctioning in the controller (maybe load switches or wiring?) but not entirely sure.

Here's a weird signal that I noticed.  Particularly the signal face on the mast arm.  Pasadena, CA:

https://www.google.com/maps/place/Pasadena,+CA/@34.1445637,-118.1229389,3a,24.9y,9.7h,92.89t/data=!3m7!1e1!3m5!1sNpda3q7ew-C-3xejSL2LWA!2e0!6shttps:%2F%2Fstreetviewpixels-pa.googleapis.com%2Fv1%2Fthumbnail%3Fcb_client%3Dmaps_sv.tactile%26w%3D900%26h%3D600%26pitch%3D-2.892983366214068%26panoid%3DNpda3q7ew-C-3xejSL2LWA%26yaw%3D9.704873725676594!7i16384!8i8192!4m6!3m5!1s0x80c2c2dc38330b51:0x52b41161ad18f4a!8m2!3d34.1476527!4d-118.144302!16zL20vMG16d3c?entry=ttu&g_ep=EgoyMDI2MDMwOS4wIKXMDSoASAFQAw%3D%3D


Why is it necessary to show green orb and straight arrow on the same signal face at the same time?  I am familiar with the "custom" of displaying a green arrow instead of a green orb on one (or more of the signal heads) to indicate that a left or right turn is not permitted, but seeing both seems quite odd.  The opposite view (i.e. southbound) with one signal face being RYG and the other being RYGA is far more common.

Definitely not something I've ever seen before.

VA Beach has them along nearly every street that crosses 21st & 22nd Streets (one-way pair that leads from/to I-264).

https://maps.app.goo.gl/PohqjmwweDSqtzMG9?g_st=ac

The exception is Pacific Ave, which has just the arrow.

I guess they really want to emphasize that the turn is not allowed. But yeah I don't see the need for the orb on the same signal. The arrow by itself, plus the no turn sign, is more than enough.

My initial guess was that it was once a left turn arrow before the street was one-way, but the signal is actually new enough you can see on GSV that it was one-way long before the signal was installed. So my second guess is someone thought a left turn was needed here and ordered a four-aspect head, and then when the installers saw it on the truck and were like "umm...ok??" they wired it up like this instead of sending it back and getting the correct three-aspect head.

They seem to be all around Pasadena, but I don't think they are present anywhere else in Southern California.  (Certainly not to the same degree.) They seem to be at any intersection with a one-way street that does not involve a turning arrow.  So they are common around Union, Green, Mentor, and Hudson, but less common on the one-way pairs around the 210 freeway (and the 710 stub freeway).

Here's another weird signal display in Baltimore:

So this is the intersection of Edmonson and Franklin in West Baltimore.  Part of US 40.  The heavy flow of traffic makes the right from Edmonson to Franklin, and they currently get a green right arrow.  Edmonson eastbound traffic also gets a green (straight arrow) at the time of this exposure. 

But what is the red light for?

Here's another exposure where the different signal heads are doing different things.  Why is the right one yellow?

If you back up a couple hundred feet from that intersection, there is an overhead "changeable" sign.  Looks like there are certain times of the day the changeable sign indicates the left center lane is a right turn only lane (and thus on the doghouse you lave a red ball with a green right arrow).

In the 2nd photo, the left center lane changeable sign may either indicate a thru only lane or a thru/right option while only the curb lane may turn right (on red ball/green arrow only).

But overall, it looks like that left center lane is normally a 3rd right turn only lane, and only certain hours of the day, it is a 2nd thru only lane (hence the lack of street arrow markings in that lane)

[CoreySamson]

There's a new flashing red right arrow traffic signal for right-turning traffic in Atoka, OK on US 69/75 at Court St here:
https://maps.app.goo.gl/MnNphzvzFivjHECc6 (GSV came in a bit too early for it to be installed; notice the spot for wiring on the right side of the horizontal pole)

The signal looks like a normal Oklahoma signal, but has two red faces, arranged horizontally. There was also a regulatory sign on the pole beside the sign, but I couldn't read it.

Someone REALLY screwed up.

[wanderer2575]

^  Are the bottom two signal sections a yellow right arrow and a green right arrow for when southbound 59 has a protected left-turn phase?  If so, I'm guessing it was someone's (mistaken) notion of how to arrange the signal sections so the red ball applies to both thru and right-turn movements.

[SignBridge]

Definitely not MUTCD compliant.

Well my question would be why were those right-turn bays closed in the first place. But obviously it is intended to be permanent. Maybe the City intends to convert that area to paved walkway or grass or whatever.

Thought about u-turn signals: I feel like the u-turn arrow lens can be hard to discern at a distance and can appear as a faulty solid RYG signal.

When they're used at RCUTs where the only 'left' movement is a u-turn, why not simply use a left arrow?

I would personally question why this would be a major concern. It may appear faulty from a distance, but it wouldn't by the time you're close enough for it to matter. Plus, with other markings and signs in place, I don't think there would be any doubt what movement the U-turn signal is for. Even if it was hard to make out the arrow.

Thought about u-turn signals: I feel like the u-turn arrow lens can be hard to discern at a distance and can appear as a faulty solid RYG signal.

When they're used at RCUTs where the only 'left' movement is a u-turn, why not simply use a left arrow?

Not really a *major concern*, but it seems like a left arrow would be adequate in this situation.
