Traffic signal

[kphoger]

Yes, a green ball plus green left arrow would suffice.

At any rate, it looks very Missouri to my eyes.

the traffic light at this intersection looks a little strange to me

This existing doghouse signal in Atlanta was modified to have a flashing yellow arrow.
Looks like they replaced the green arrow with a bimodal green / flashing yellow arrow.

Atlanta has a good few of those. I believe Minnesota uses them some as well.

First used in Minnesota.  Eau Claire WI also uses them.

Some of the Atlanta ones aren't even bimodal - that is, the flashing yellow section can't ever be green.

Greetings from San Francisco!

I saw this bicycle signal on the north approach to the Golden Gate Bridge.  There was some maintenance equipment on the east sidewalk, but even more on the west walk.  The views are better on the east anyway.

Also in Sausalito, I found a deactivated traffic light where they just turned the heads away.  If they were covered up, the hoods are long gone now.

Nice find! Can't imagine California has too many abandoned traffic lights left standing like that.

Unusual left and green arrows in the middle instead of a green ball.  The left and right heads display both a ball and arrow that is also odd as there are no separate signals here or any protected turns.

Also never seen before detector loops like this being completely round.

Wow, really? These are crazy common where I'm from (WA). I think they're common in the West, generally.

Are they normally square back East?

[SignBridge]

Loops are normally rectangular shaped here on Long Island. 

[ErmineNotyours]

I finally got a chance to photograph an old style weigh station messaging signal sign.  New installations have variable messaging, and even tells the driver the weight.  This one is northbound U.S. 101 heading in to Raymond, Washington.  Additionally, due to limited space, it's mounted behind the driver, so it's mirrored for viewing in the rear view mirror.  The scale house is normally boarded up, but one window was left uncovered.  I could see inside and saw a calendar for 1997.  It probably doesn't get used much.

Detector loops arranged in a square layout (technically an octagon, but with much smaller sides at the corners so that the overall appearance is a square) is still very common in Nevada. It's only been in the last 5-10 years or so that new and reconstructed loops are being installed as circles.

I think square loops may have been a bit better in detecting lighter vehicles (like motorcycles favoring one side of the lane), but my understanding is that the corners on the loops were more susceptible to damage under repeated vehicle loads over time and/or as asphalt pavement deforms.

[Rothman]

NYSDOT has a policy of replacing all loops wirh video detection.  Certain Regions are more aggressive than others in implementing it.

[SignBridge]

Nassau County DPW on Long Island is no longer installing detector loops. All new and rebuilt signals have motion detectors mounted on the mast-arms.

However in contrast to that modern practice, I have not yet seen a single flashing-yellow arrow on a Nassau County signal, though NYS DOT Region-10 is putting in a lot of them on state highways.

Double green balls on the four-section signal on this approach in Guerneville, California - it appears this approach was split phased initally with left and right arrows, and then it got changed to a fully permissive setup some time later.

The fact that CalTrans or someone stuck the yellow reflective tape on the heavily faded backgrounds there is kind of amusing.

The fact that the mast-mounted signals on the one side there are all 12 inch while the rest mostly have 8 inch mast-mounted signals makes me think that side originally used arrow indications in all signals before being changed, I'm guessing to accomodate a pedestrian phase better.

^^ Traffic can't go straight, so I think flashing yellow arrows would be more appropriate.

Old 8in pedestrian signals got replaced with 12in heads instead of actual ped signals.
https://maps.app.goo.gl/S2z28BibXSgAWwwP7
Also having 12in heads with no overheads just looks cool

Very California-like.

Not pedestrian signals, those were actually just 8-inch side mounted signals, used for both traffic and pedestrians.

Since it's oneway they now technically acting as ped signals

Found these left turn signals with an unusual lens layout.
